Drought monitoring and declaration in India are challenging due to requirement of multiple drought indices representing meteorological, hydrological, and agricultural droughts that are often not available in near real-time. In addition, the current drought monitoring efforts do not consider groundwater storage variability. To overcome this, we deve...

Despite the implications of meteorological drought propagation to agricultural, hydrological, and groundwater droughts, the focus of previous studies has been primarily on meteorological droughts in India. We use the well‐calibrated and evaluated Variable Infiltration Capacity‐ Simple Groundwater Model (VIC‐SIMGM) to simulate soil moisture, runoff,...

Rapid groundwater depletion due to anthropogenic pumping for irrigation poses enormous challenges on socio‐economic, agricultural, and financial spheres of India. However, the role of groundwater depletion on flood potential in India remains unexplored. We examine the role of changes in terrestrial water and groundwater storage on flood potential u...

Human activities associated with intensive irrigation, reservoir storage, and groundwater pumping have substantially altered the hydrological cycle, environment, and regional climate in India. However, the role of human activities on water budget and droughts remain mostly unexplored. We use calibrated and evaluated Community Water Model (CWatM) to...

Plain Language Summary Reservoirs are the prime source of water during droughts. However, water supply from reservoirs depends on how much water reservoirs have. Reservoirs lose significant amounts of water through evaporation. Hence, understanding reservoir droughts by incorporating evaporation information—will help water managers to better regula...

This paper provides a review and summary status of the research underway by the NASA Terra Aqua Suomi-NPP Land Discipline Team to provide continuity of global land data products from the NASA Moderate resolution Imaging Spectroradiometer (MODIS) to the Visible Infrared Imaging Radiometer Suite (VIIRS). The two MODIS instruments on the NASA Earth Ob...

Reservoirs play a crucial role in regulating water availability and enhancing water security. Here, we develop NASA’s Visible Infrared Imaging Radiometer Suite (VIIRS) based Global Water Reservoir (GWR) product, consisting of measurements of reservoir area, elevation, storage, evaporation rate, and evaporation loss for 164 large global reservoirs....

Global reservoir information can not only benefit local water management but can also improve our understanding of the hydrological cycle. This information includes water area, elevation, and storage; evaporation rate and volume values; and other characteristics. However, operational wall-to-wall reservoir storage and evaporation monitoring informa...

Drought is among the costliest natural disasters that affect the economy, food and water security, and socioeconomic well‐being of about 1.4 billion people in India. Despite the profound implications of droughts, the propagation of meteorological to hydrological droughts in India is not examined. Here, we use observations and simulations from a wel...

Groundwater is a vital resource to support food and freshwater security in India. Changes in climate and anthropogenic activities affect groundwater storage. Here, we examine the role of precipitation and policy changes on groundwater storage in western India (WI) using observed well data from Central Groundwater Board (CGWB) and satellite data fro...
