Developing a geomorphological instantaneous unit hydrograph (GIUH) using equivalent Horton-Strahler ratios for flash flood predictions in arid regions

open access: yesGeomatics, Natural Hazards & Risk, 2020
The Horton-Strahler ratios are important to describe the stream network and to identify the hydrologic response of a basin using the GIUH concept. These ratios are often sensitive to the selected threshold area for the extraction of the stream network ...

California's Central Valley Groundwater Wells Run Dry During Recent Drought

open access: yesEarth's Future, 2020
Declining water tables are causing wells to run dry in California, but the prevalence and spatial distribution of wells that have run dry are not known beyond anecdotal and voluntary reports. Here, we apply a new, simple, and measurement‐driven method to

Hydrological processing of salinity and nitrate in the Salinas Valley agricultural watershed [PDF]

open access: yesEnvironmental Monitoring and Assessment, 2021
AbstractRegime shifts of major salinity constituents (Ca, Mg, Na, K, SO4, Cl, HCO3, and NO3) in the lower Salinas River, an agricultural ecosystem, can have major impacts on ecosystem services central to continued agricultural production in the region. Regime shifts are large, persistent, and often abrupt changes in the structure and dynamics of social-
