In this paper, field hydrological monitoring tests and an analytical solution for the aquifer response (i.e., groundwater head) to stream-stage fluctuations are presented through a case study of Yangtze River in Wuhan, China. A sinusoidal equation stream water level over time is proposed verified by results. Based on classical 1-D ground flow equations, new model was analyze confined fluctuatio...

Microscopic understanding of tree xylogenesis processes and their relationships with environmental factors is important for conservation. To assess the relationship between Euphrates poplar (Populus euphratica) radial growth on short time scales, micro-core samples were collected in lower Tarim River northwest China 2020. We analyzed intra-annual variation P. euphratica its environment. Our res...

Groundwater irrigation has been instrumental in enhancing food security and, arguably, in mitigating poverty in developing countries. Groundwater provides timely irrigation, leading to an increase in crop intensity and productivity (Food and Agriculture Organization 2003). But groundwater irrigation also contributes the most to the depletion of groundwater reserves. Countries with significant g...

Groundwater from the coastal aquifers north of Chennai is being pumped since 1981 to meet the increasing demand. Huge groundwater extracting in the coastal aquifers groundwater causes lowering of groundwater table which led to seawater intrusion. The objective of this study is to assess the behavior of this aquifer to seawater intrusion under different hydrological stresses by groundwater model...

Abstract This paper presents a novel approach for an improved estimate of regional groundwater storage (GWS) change in Northwestern India by integrating satellite-based Gravity Recovery and Climate Exchange (GRACE) gravity observation hydrological modelling satellite/in situ hydrometeorological data. Initially, GRACE observation-based terrestrial water (TWS) model-based TWS products were integr...

Since the beginning of 1980s, several regions in northern Sahara Algeria have been confronting rising groundwater. Among all these regions, Oued Souf Valley represented one most acute affected by this phenomenon. Due to natural topography and insufficient/weakness water management miscoordination between different sectors that are intensive exploitation deep groundwater reservoirs which returns...

Despite modeling groundwater as a common property resource, existing economic analyses find that the quantitative difference between competitive and socially optimal groundwater management outcomes is negligible. Thus, in contrast to the public perception of groundwater overextraction and resource depletion, there appears to be no economic rationale for groundwater management. In this paper, we...

Groundwater is an important source of potable water because it is abundant and readily available in many locations and often requires little or no treatment. In 1995, groundwater accounted for approximately 20% of potable water use in the U.S., and approximately 50% of the U.S. population relied on groundwater for their source of drinking water. In most European countries, groundwater accounts ...
