Basin‐scale dataset reveals widespread hydrocarbon venting at the seafloor in the northern Gulf of Mexico. Hydrocarbon release at the seafloor is related to the occurrence of the underlying Louann salt and the gas hydrate stability zone. ABSTRACT The release of hydrocarbons, pore water and fluidized sediments impacts seafloor morphology, marine ...

Retrogressive Thaw Slumps Produce a Changing Disturbance Regime for Arctic Stream Invertebrates
Climate change is causing permafrost to thaw, resulting in the formation of large craters in the ground called thaw slumps, which deposit sediments and nutrients into rivers and continually impact stream ecosystems over time. We returned to slump impacted streams 10 years after an initial sample period and found that slumps permanently change streams ...

Can Flash Flood Risk Index Be an Early Warning Signal of Flash Floods in Ungauged Basin?
ABSTRACT Flash flooding is amongst the most severe natural hazards, causing widespread socioeconomic impacts across both wet regions and drylands. In ungauged mountainous basins, effective risk warning based on hydrodynamic modelling is challenging due to sparse hydrological observations and complex terrain.

High‐Resolution Channel Geometry Reveals Contrasting Styles of Gravel River Adjustment
Abstract Rivers self‐organize to convey water and sediment, giving rise to robust downstream scaling between channel geometry and drainage area, underpinning landscape evolution models. However, these relations rely on limited observations per watershed. We quantify downstream changes in channel slope and bankfull width for six gravel rivers.

Stream network analysis and geomorphic flood plain mapping from orbital and suborbital remote sensing imagery application to flood hazard studies in central Texas [PDF]
The author has identified the following significant results. Development of a quantitative hydrogeomorphic approach to flood hazard evaluation was hindered by (1) problems of resolution and definition of the morphometric parameters which have hydrologic ...
