Post-Fire Erosion Following The Czu Lightning Complex Fire: Quantifying Hillslope Erosion And Providing Guidance Towards Improving Post-Fire Response, Matthew C. Crockett, Matthew Crockett
Master of Science in Environmental Sciences and Management Projects
The size and severity of wildfires have increased in California during recent decades. This trend is highlighted through the CZU Lightning Complex fire of August 2020 which burned over 86,000 acres in the Santa Cruz mountains of California. The fire greatly impacted the Little Creek watershed, a roughly 1,300 acre watershed that exists largely within Cal Poly San Luis Obispo’s Swanton Pacific Ranch (SPR). The current trends of California’s increased wildfire regime are expected to continue, raising concerns regarding the direct and secondary effects on forest watersheds and the effectiveness of current post-fire erosion control management. Accelerated rates of erosion …
Post-Fire Response Of Little Creek Watershed: Evaluation Of Change In Sediment Production And Suspended Sediment Transport, Andrew Wood Loganbill
Post-Fire Response Of Little Creek Watershed: Evaluation Of Change In Sediment Production And Suspended Sediment Transport, Andrew Wood Loganbill
Master's Theses
The Little Creek watershed was assessed to identify changes in event-based suspended sediment export and determine the factors contributing to sediment production the first year following the Lockheed Fire in 2009. The amount and volume of near-stream sediment sources were found to decrease, while an increase in hillslope sediment production was documented. High intensity, short duration rainfall (up to 87 mm/hr for 10 minute duration) initiated extensive rilling and minor channel-derived debris torrents originating from the upper south facing slopes. Rainfall simulations, hillslope erosion plots, and soil infiltration tests indicated that fire produced soil water repellency, the lack of ground …
