Satellite-based estimates of groundwater depletion in India

  title={Satellite-based estimates of groundwater depletion in India},
  author={Matthew Rodell and Isabella Velicogna and James S. Famiglietti},
Groundwater is a primary source of fresh water in many parts of the world. Some regions are becoming overly dependent on it, consuming groundwater faster than it is naturally replenished and causing water tables to decline unremittingly. Indirect evidence suggests that this is the case in northwest India, but there has been no regional assessment of the rate of groundwater depletion. Here we use terrestrial water storage-change observations from the NASA Gravity Recovery and Climate Experiment… 

Groundwater Storage and Depletion Trends in Tamil Nadu State, India

Groundwater irrigation is the most predominant method used across India. The south Indian state of Tamil Nadu is one of the largest producers of agricultural products, and is largely dependent on

Groundwater Storage Changes in China from Satellite Gravity: An Overview

An overview of GWS changes in three main aquifers within China using GRACE data is presented, and a comprehensive accuracy assessment using in situ ground well observations and hydrological models is conducted.

Satellites measure recent rates of groundwater depletion in California's Central Valley

In highly‐productive agricultural areas such as California's Central Valley, where groundwater often supplies the bulk of the water required for irrigation, quantifying rates of groundwater depletion

Remotely sensed groundwater storage variations in Hai River basin, China

It can be further inferred that intensive abstraction in summer may alters specific yield, which is a commonly used parameter for validating GRACE-derived groundwater storage, which stands for terrestrial water storage and soil water storage, respectively.

Monitoring Groundwater Storage Changes Using the Gravity Recovery and Climate Experiment (GRACE) Satellite Mission: A Review

The GRACE-based groundwater changes revealed significant aquifer depletion over large regions, but were also used to estimate groundwater-related parameters such as the specific yield, which relates groundwater level to storage, or to define the indices of groundwater depletion and stress.

Groundwater storage and depletion trends in the Loess areas of China

Groundwater is the essential source of drinking and irrigation water supplies in most parts of the world. The Loess area is one among the largest manufacturers of agricultural merchandise in China

GRACE Detected Rise of Groundwater in the Sahelian Niger River Basin

West African regions along the Niger River experience climate and land cover changes that affect hydrological processes and therewith the distribution of fresh water resources (WR). This study


Groundwater is one of the most valuable sources of fresh water in many places worldwide, especially in regions with low pluviometric indices such as northern Chile. Thus, it is mandatory to monitor

Applying satellite‐derived evapotranspiration rates to estimate the impact of vegetation on regional groundwater flux

Freshwater resources are at a premium across the world, including many water‐limited areas across Australia. Ongoing water level decline in some groundwater systems suggests that the rate of loss may



Estimating groundwater storage changes in the Mississippi River basin (USA) using GRACE

Based on satellite observations of Earth’s time variable gravity field from the Gravity Recovery and Climate Experiment (GRACE), it is possible to derive variations in terrestrial water storage,

Remote sensing of groundwater storage changes in Illinois using the Gravity Recovery and Climate Experiment (GRACE)

Regional groundwater storage changes in Illinois are estimated from monthly GRACE total water storage change (TWSC) data and in situ measurements of soil moisture for the period 2002–2005.

Water resources and climate change: An Indian perspective

In recent times, several studies around the globe show that climatic change is likely to impact significantly upon freshwater resources availability. In India, d emand for water has already increased

An analysis of terrestrial water storage variations in Illinois with implications for the Gravity Recovery and Climate Experiment (GRACE)

Variations in terrestrial water storage affect weather, climate, geophysical phenomena, and life on land, yet observation and understanding of terrestrial water storage are deficient. However,

Water resources of India

The paper presents availability and demands of water resources in India as well as describes the various issues and strategies for developing a holistic approach for sustainable development and management of the water resources of the country.

Relations between precipitation and shallow groundwater in Illinois

Abstract The statistical relationships between monthly precipitation (P) and shallow groundwater levels (GW) in 20 wells scattered across Illinois with data for 1960–84 were defined using

One million year old groundwater in the Sahara revealed by krypton‐81 and chlorine‐36

Measurements of 81Kr/Kr in deep groundwater from the Nubian Aquifer (Egypt) were performed by a new laser‐based atom‐counting method. 81Kr ages range from ∼2 × 105 to ∼1 × 106 yr, correlate with

Multi‐sensor analysis of water storage variations of the Caspian Sea

We perform a multi‐sensor analysis of water storage and surface height variations of the Caspian Sea, from mid‐2002 through 2006. Data from three satellite missions (GRACE, Jason‐1, and Aqua) are

GRACE Measurements of Mass Variability in the Earth System

Geoid variations observed over South America that can be largely attributed to surface water and groundwater changes show a clear separation between the large Amazon watershed and the smaller watersheds to the north.

Acceleration of Greenland ice mass loss in spring 2004

The rate of ice loss increased by 250 per cent between the periods April 2002 to April 2004 and May 2004 to April 2006, almost entirely due to accelerated rates of ice Loss in southern Greenland; the rate of mass loss in north Greenland was almost constant.
