Abstract The steep, tectonically active terrain along the Central California (USA) coast is well known to produce deadly and destructive debris flows. However, extent which fire affects debris-flow susceptibility in this region an open question. We documented occurrence of postfire floods flows following landfall a storm that delivered intense rainfall across multiple burn areas. used inventory evaluate predictive performance US Geological Survey M1 likelihood model, tool presently underlies...

Abstract In a warming climate, an intensifying fire regime and higher likelihood of extreme rain are expected to increase watershed sediment yield in many regions. Understanding regional variability landscape response post‐fire rainfall is essential for managing water resources infrastructure. We measured resulting from sequential wildfire flooding the upper Carmel River (116 km 2 ), on central California coast, USA, using changes volume mapped reservoir. determined that after was 854–1,100...
Abstract Measuring river response to dam removal affords a rare, important opportunity study fluvial sediment pulses on large field scale. We present before–after/control–impact of the Carmel River, California, measuring geomorphic and grain‐size evolution over 8 years, six which postdated 32 m‐high (one largest dams removed worldwide) included 11 flow events exceeding 2‐year flood magnitude. find that reservoir‐sediment pulse following was relatively small (97 000 ± 24 t 4 years), owing...
Abstract Dam removal provides a valuable opportunity to measure the fluvial response changes in both sediment supply and processes that shape channel morphology. We present first study of river large (32‐m‐high) dam Mediterranean hydroclimatic setting, on Carmel River, coastal California, USA. This before‐after/control‐impact measured topography, grain size, salmonid spawning habitat throughout subsequent major floods. During removal, course was re‐routed order leave most impounded...
Abstract A 1200 m‐long river segment of Carmel River (California) was constructed to bypass trapped reservoir sediment when San Clemente Dam removed from the in 2015. Hundreds large boulders were used construct 53 steps an 800 reach project. Nearly all scattered new locations high flows 2017, and have been relatively stable since that time. We analysed causes incipient motion distance travelled for 226 randomly selected (0.5–1.8 m) impacted by a flood event winter 2019. Channel width, water...
Spawning gravel scarcity is a limiting factor for successful recovery of federally-threatened anadromous fish like steelhead central California. A BACI-experimental design using bed particle counts from 2013 through 2021 shows that spawning-sized (32–90 mm) diminished downstream the former San Clemente Dam site in 2017, following dam removal 2015. High flows 2017 transported pulse sand and fine-gravel filled pools runs throughout river below dam. The material 3 km closest to remained too...
