BAER Scientists Assess the Oak Fire for Flooding Debris Flow Risks

Related Incident: Oak Post-Fire BAER
Publication Type: News

BAER Scientists and Specialists Assess the Oak Fire for Flooding and Debris Flow Risks

After a large wildfire, special actions are often necessary to provide for public safety and protect critical cultural and natural resources. Some fires create situations that require special efforts to prevent additional damage after the fire is contained. Loss of vegetation exposes soil to erosion; water runoff may increase and cause flooding, sediments may move downstream and damage houses or fill reservoirs and put endangered species and community water supplies at-risk. A Forest Service Burned Area Emergency Response (BAER) team is assessing federal lands burned in the Oak Fire, with the goal of keeping visitors and employees safe while recreating and working in the Sierra National Forest (NF). BAER team assessments focus on emergency actions that are necessary to protect human life and safety, property, critical cultural resources, and critical natural resources such as soil productivity, hydrologic function, and water quality. Emergency actions are intended to minimize any further damage during rainstorm events. BAER hydrologists, soil scientists, geologist, road engineers, recreation specialists, biologists, botanists, archeologists, and GIS specialists are currently assessing the condition and response of the watersheds within the Oak burned areas. These BAER scientists and specialists evaluate other critical values that could be at risk during major rainstorm events such as forest roads and trails, campgrounds, and other forest infrastructure.

BAER soil scientists evaluate the burned watersheds to determine post-fire effects to soil and watershed conditions. This includes testing whether the soil is hydrophobic – aka repels water. Post-Fire burned areas of hydrophobic (water repellent) soils can act as a “tin roof” by reducing infiltration capacity of soils, enhanced overland flow, and accelerated soil erosion.

This is important because the amount of hydrophobicity is an important component to determining how much increased water runoff we can expect after a fire. The hydrophobic layer is the result of a waxy substance that is derived from plant material burned during a hot fire. The waxy substance penetrates the soil as a gas and solidifies after it cools, forming a waxy coating around soil particles. Hydrophobicity repels water from soil and is considered when mapping watershed response to rainstorms after a wildfire.

Below, these three photos show Forest Service soil scientist Curtis Kvamme assessing soil hydrophobicity (water repellency) and changes to soil structure in a high soil burn severity (SBS) area of the Oak burned area. Curtis digs a trench and drops water on the soil at multiple depths to determine how deep and how strong the layer of water-repellant soil may be.

In the next two photos, Curtis captures high soil burn severity data in the Oak burned area using Survey 123 data collection program to evaluate and map the level of severity for this part of the fire.

In addition to the BAER team’s ground surveys of the Oak burned area, air reconnaissance flights are sometime critical for the BAER specialists to see an aerial overview of the burn area.

The photo below is an aerial view of a portion of the Oak burned area that was taken by Forest Service Geologist Yonni Schwartz during an air reconnaissance flight. The photo shows gentle valleys and ridges formed by fluvial erosion processes which shaped a relatively smooth landscape that is devoid of instable geological features.

Image showing an aerial view of a portion of the Oak burned area

To prepare for his geology and debris flow hazards assessment, Yonni first examined the coverages of bedrock and geomorphology on the Sierra National Forest by looking at GIS maps, before conducting in-person field verifications. Yonni also reviewed geologic maps to identify pre-fire slope failures, pre-fire slope, channel failure deposits, measurements of slopes, and geological units. His field verification of soil burn severity, notes of observations and photography were used for his geology assessment of the Oak burned area.

Yonni’s photo below shows a channel that is loaded with a thick layer of mostly fine sediments, that are lacking any surface rocky materials that could produce a hyper-concentrated sediment flow during a major rainstorm event.

Image showing A channel that is loaded with a thick layer of mostly fine sediments within the Oak burned area

This photo below is of the lower end of Snow Creek that is loaded with unsorted, unconsolidated rocky materials that is available to be transported downstream as a destructive debris flow during a major rainstorm event.

Image showing Lower end of Snow Creek with rocky material in Oak Burned Area

BAER Engineers evaluated roads and bridges within the Oak burned area for potential threats from flash flooding, sediment flows impacting drainage crossings and the overall infrastructure due to increased erosion, sedimentation, and water flows. They also determine whether road culverts within the burned area have sufficient capacity to pass post-fire modeled increased water and debris flows—in particular, they look to see if they are clogged, collapsed, or could get clogged after major rainstorm events. Roads are BAER critical values that need to be assessed for these threats. The BAER team will recommend emergency stabilization treatments and actions to minimize those threats.

The photo below is an example of several critical drainage crossings identified by BAER assessment team road engineers, hydrologist and geologist. They inspected these crossings to prescribe the most effective BAER treatment to protect the road prisms from washing away during major storm events.

Image showing Critical road drainage crossing assessed by BAER specialists in Oak burned area

This photo below is an aerial view above Forest Service roads 5S24 and 4S33. Both roads are below a high soil burn severity area of the Oak Fire that is expected to have a potential significant increase in water run-off. Consequently, predicted debris flows could exceed the capacity of current road drainage features. BAER stabilization treatments will be recommended and implemented to protect these roads for Forest visitors and employees traveling in the Sierra NF.

Image showing Aerial view above FS roads 5S24 & 4S33 in Oak burned area

In the next two photos below, Forest Service Transportation Engineer Marcos Rios is inspecting and evaluating risk at a Triangle Road bridge on Snow Creek. Marcos assessed the bridge to determine if it had capacity for potential increased stream and debris flows that is likely to come down the burned watershed during rainstorm events.

In the next two photos, Marcos Rios, BAER Team Leader Kendal Young, and Sierra NF Roads Manager Pablo Gonzalez, evaluate soil burn severity conditions along roads within the Oak burned area. The second photo shows Kendal and Marcos looking to determine if there is a BAER stabilization treatment that would prevent hazmat from a burned structure from reaching a creek.

Along with roads, trails are also a BAER critical value that need to be assessed for potential threats from flash flooding, debris flows impacting drainage crossings and the overall trail prisms and infrastructure due to increased erosion, sedimentation, and water flows. Forest Service Recreation Specialist Cori Hayth assessed trails within the Oak burned area.

The two photos below show portions of two trails Cori evaluated for the BAER team report and provided BAER emergency stabilization treatment recommendations to minimize threats from potential rainstorm threats.

Oak PostFire BAER Soil Burn Severity Map Released

OAK POST-FIRE BAER SOIL BURN SEVERITY MAP RELEASED

JPG Image showing Oak Post-Fire BAER Soil Burn Severity Map

On August 12, 2022, Forest Service BAER team specialists completed its field data gathering on federal lands burned by the Oak Fire. The post-fire map and the data display soil burn severity (SBS) categories of unburned/very low, low, moderate, and high.

The BAER team analyzed 19,480 acres and its burned watersheds for the different levels of SBS. Approximately 34% of the total acres are either unburned/very low or low SBS, while 45% are moderate SBS and 21% are high SBS.

The BAER team’s assessment shows the acreage for land ownership for the 19,480 acres to be:

  •   9,204 acres of Sierra National Forest (NF) land,
  • 10,221 acres of private lands; and
  •        55 acres of Bureau of Land Management (BLM) land.

The BAER assessment team used preliminary remote sensing data based on satellite imagery of the fire perimeter from August 5, 2022, with field-validated data collected over several days to produce the final Oak Post-Fire SBS map.

The BAER assessment team coordinates with other local and federal agencies such as county and state officials, California Office of Emergency Services (CALOES), Natural Resources Conservation Service (NRCS), National Weather Service (NWS), and USGS to share information about burned watershed conditions and their predicted response during certain rain events.

The SBS map product is an estimate of fire effects on soils and not a measure of direct effects to vegetation. SBS characterizes the soil surface and below-ground impact, whereas effects on vegetation are estimates of mortality based primarily on changes in vegetation canopy. The Rapid Assessment of Vegetation Condition after Wildfire (RAVG) program produces data describing post-fire vegetation conditions on federal lands. Changes in overhead and understory vegetation canopy are often used as initial indicators of overall vegetation burn severity, but do not necessarily coincide with SBS.

Changes in soil cover, water repellency, and soil physical/biological conditions guide the interpretations to determine the severity burn level of the soil. Water repellency can occur naturally in soil and may change as a function of fire. Fire can increase the strength and thickness (or depth) of water-repellent layers in soil, considerably affecting post-fire water runoff and possibly extending time for recovery of the burned area.

Soil burn severity indicators can be found within the Rocky Mountain Research Station’s General Technical Report 243 – Field Guide for Mapping Post-Fire Soil Burn Severity https://www.fs.fed.us/rm/pubs/rmrs_gtr243.pdf and are described below.

Low SBS generally occurs where surface organic layers are not completely consumed and are still recognizable. Structural aggregate stability is not changed from its unburned condition, and roots are generally unchanged because the heat pulse below the soil surface was not great enough to consume or char any underlying organics. The ground surface, including any exposed mineral soil, may appear brown or black (lightly charred), and the canopy and understory vegetation will likely appear “green.” Lower risk for accelerated runoff, erosion, flooding and debris flows is expected within and below these areas compared to moderate and high SBS.

In areas with moderate SBS, up to 80% of the pre-fire ground cover (litter and ground fuels) is consumed. Fine roots may be scorched but are rarely completely consumed over much of the area. The color of the ash on the surface is generally blackened with possible gray patches. There may be potential for recruitment of effective ground cover from scorched needles or leaves remaining in the canopy that will soon fall to the ground. The prevailing color of the site is often “brown” due to canopy needle and other vegetation scorch. Soil structure is generally unchanged. Where greater amounts of reduced soil cover and increased water repellency occur, increased overland flow of water from precipitation is expected, most notably in locations where the overstory canopy no longer exists.

High SBS occurs where all or nearly all the pre-fire ground cover and surface organic matter (litter, duff, and fine roots) are consumed, and charring may be visible on larger roots. The prevailing color of the site is often “black” due to extensive charring. Bare soil or ash is exposed and susceptible to erosion, and aggregate structure may be less stable. White or gray ash (up to several centimeters in depth) indicates that considerable ground cover or fuels were consumed. Sometimes very large tree roots are entirely burned extending from a charred stump hole. Soil is often gray, orange, or reddish at the ground surface where large fuels were concentrated and consumed.

Generally, there is 100% tree mortality in high SBS, and tree recovery will take many years without planting. In high SBS, the exposed bare soil is very prone to post-fire impacts. Rain events on damaged soil can cause excessive soil erosion, resulting in higher volumes of sediment delivery to adjacent creeks and rivers. There is increased likelihood for flooding and debris flows. These threats can individually or cumulatively increase the risk to human life and safety, property, infrastructure, and important critical natural and cultural resources.

The BAER team will use the Oak SBS data to analyze and model post-fire hydrologic response for each of the watershed to determine if there are any threats or risks to BAER critical values. The team shares its analysis with cooperating agencies who have the authority to work with private property owners downstream from the burned area that potentially may have post-fire threats from increased water and debris flows. The BAER team’s analysis and findings will be documented in an assessment report that will be posted to the Oak Post-Fire BAER InciWeb page after the report has been reviewed and approved by Forest Service leadership.

The Oak Fire SBS map can be downloaded at the “Oak Post-Fire BAER” InciWeb site (https://inciweb.nwcg.gov/incident/8325/) as a JPEG or PDF version under the “Maps” tab.

Forest Service BAER Team Begins Oak PostFire Assessment

Related Incident: Oak Post-Fire BAER
Publication Type: News

FOREST SERVICE BAER TEAM BEGINS OAK POST-FIRE ASSESSMENT

A Forest Service Burned Area Emergency Response (BAER) team has been established by the Sierra National Forest (NF) to begin a joint burned area assessment of the Oak Fire that recently burned on Forest Service and Bureau of Land Management (BLM) federal lands, and private lands. The Oak BAER team leader is Kendal Young, Forest Service Natural Resources Staff Officer, and Co-Team Leader is Marcos Rios, Forest Service Engineer. Personnel from California State Office of Emergency Services (CALOES) and Natural Resources Conservation Service (NRCS) are evaluating burned private and county lands and infrastructure.  CALOES and NRCS and the Forest Service BAER Team will be sharing information and data as they complete their assessments and subsequent reports. Forest Service BAER team assessments typically take approximately two weeks to complete.

In addition to working and coordinating with Sierra NF staff, NRCS and CALOES, the team is coordinating with the National Weather Service (NWS), US Geological Survey (USGFS), and other federal, state, and local agencies as they assess potential post-fire impacts to the burned watersheds.

BAER surveys are rapid assessments that evaluate the burned area to identify watersheds having increased potential for post-fire flooding, sediment flows and rockslides, and assist land managers prepare the burned area for the upcoming monsoon rains. The team focus is on potential emergency impacts to life, and safety on federal land but model hydrologic response throughout the burned area and share the team’s findings with the responsible downstream agencies.

BAER teams may consist of scientists and specialists including hydrologists, geologists, soil scientists, road engineers, botanists, biologists, archeologists, and geographic information specialists. BAER teams collect field data during their burned area surveys to analyze through GIS and computer models and present their findings along with recommended BAER emergency stabilization treatments in a BAER assessment report.

BAER teams utilize satellite imagery and specialist data to analyze and produce a runoff map that shows the levels of hydrological potential flows during rain events.  This is the first step in assessing potential watershed impacts from wildfires to any federal values that may be at-risk from potential increased flooding, sedimentation, debris flows, and rockslides.  BAER teams produce a report that describes potential threats associated with the burned area’s post-fire conditions sometimes including recommended emergency stabilization measures and actions.  BAER emergency response efforts are focused on the protection of human life, safety, and property, as well as critical cultural and natural resource values such as the water quality of streams and wetlands on federal lands.

BAER reports are shared with interagency cooperators who work with downstream private home and landowners to prepare for potential post-fire flooding and debris flow impacts.  Homes or businesses that could be impacted by flooding from federal land that resulted from wildfires may be eligible for flood insurance coverage from the National Flood Insurance Program (NFIP).  Information about NFIP is available through FEMA at www.fema.gov/national-flood-insurance-program, or www.floodsmart.gov/wildfires. Other flood preparedness information is available at www.ready.gov/floods at www.floodsmart.gov/.

BAER SAFETY MESSAGEEveryone near and downstream from the burned areas should remain alert and stay updated on weather conditions that may result in heavy rains and increased water runoff. Flash flooding may occur quickly during heavy rain events – be prepared to act.
