TL;DR: In this article, the authors examined the economic costs of pumping replacement groundwater during drought and the potential loss of pumping capacity as groundwater levels drop in California's Central Valley, showing that places without access to groundwater and with uncertain surface-water deliveries during drought are the most economically vulnerable in terms of crop revenues, employment and household income.

TL;DR: Results show that adhesion properties governed by the electrophoretic mobility of purified C. parvum oocysts can be altered by the method of purification and that hydrophobicity can change as oocyst age.

TL;DR: Transport of Cryptosporidium parvum oocysts through three substrates was used to determine dispersion, retardation, and first-order decay parameters for the convective dispersion equation (CDE), suggesting oocyst may travel significant distances in both subsurface and overland flow.

TL;DR: In this article, a series of drought simulations were performed for the California Central Valley using computer applications developed by the California Department of Water Resources and historical datasets representing a range of droughts from mild to severe for time periods lasting up to 60 years.

TL;DR: A reservoir system analysis model that utilizes an LP solver is linked directly to a non-linear, three-dimensional, finite element groundwater model, a general-purpose model that can be applied to any basin with no code changes.
