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

Assessing the demand for hydrological drought insurance in irrigated agriculture
Agricultural Water Management, 2022 Concerns about hydrological drought risk and irrigation water supply reliability have grown in recent years due to the increasing demand for water for irrigation and other uses, and the decline in water availability due to climate change. Hydrological drought insurance hedging against water supply gaps can be a key instrument for adapting irrigated ...

Perspectives of Hydrologic Modeling in Agricultural Research
, 2021 For decades agricultural research was done in the field or laboratories, but with the rise of computer science, hydrologic modeling became another essential tool for environmental impact studies. Many types of models can be used, each with its strengths and weaknesses in terms of accuracy, speed, and amount of input data needed.
