Impact of sensor placement in soil water estimation: A real-case study [PDF]
, 2022 One of the essential elements in implementing a closed-loop irrigation system is soil moisture estimation based on a limited number of available sensors. One associated problem is the determination of the optimal locations to install the sensors such that good soil moisture estimation can be obtained.

Predicting Playa Inundation Using a Long Short-Term Memory Neural Network [PDF]
, 2020 In the Great Plains, playas are critical wetland habitats for migratory birds and a source of recharge for the agriculturally-important High Plains aquifer. The temporary wetlands exhibit complex hydrology, filling rapidly via local rain storms and then drying through evaporation and groundwater infiltration.

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