Projecting groundwater storage changes in California's Central Valley. [PDF]

Sci Rep, 2018
AbstractAccurate and detailed knowledge of California’s groundwater is of paramount importance for statewide water resources planning and management, and to sustain a multi-billion-dollar agriculture industry during prolonged droughts. In this study, we use water supply and demand information from California’s Department of Water Resources to develop ...

Spatio-temporal variability of groundwater storage in India. [PDF]

J Hydrol (Amst), 2017
Groundwater level measurements from 3907 monitoring wells, distributed within 22 major river basins of India, are assessed to characterize their spatial and temporal variability. Groundwater storage (GWS) anomalies (relative to the long-term mean) exhibit strong seasonality, with annual maxima observed during the monsoon season and minima during pre ...

Estimation of groundwater storage loss using surface–subsurface hydrologic modeling in an irrigated agricultural region [PDF]

Scientific Reports
In the Mississippi alluvial plain (MAP) area, the demand for groundwater resources from the alluvial aquifer for agricultural irrigation has led to significant reductions in groundwater-level elevation over time.

Improving the Accuracy of Groundwater Storage Estimates Based on Groundwater Weighted Fusion Model [PDF]

Remote Sensing, 2022
It is an effective measure to estimate groundwater storage anomalies (GWSA) by combining Gravity Recovery and Climate Experiment (GRACE) data and hydrological models. However, GWSA results based on a single hydrological model and GRACE data may have greater uncertainties, and it is difficult to verify in some regions where in situ groundwater-level ...

Flow and Storage in Groundwater Systems [PDF]

Science, 2002
The dynamic nature of groundwater is not readily apparent, except where discharge is focused at springs or where recharge enters sinkholes. Yet groundwater flow and storage are continually changing in response to human and climatic stresses. Wise development of groundwater resources requires a more complete understanding of these changes in flow and ...
