Denmark occupies a total area of some 43,000 km. Most of the c ountry consists of Quaternary deposits overlying Cretaceous chalk, limestone, and Tertiary sand and clay. The topography is low-lying, reaching a maximum of 172 m above sea level. The combination of lo w topography and widespread, consolidated, and unco nsolidated aquifers ensures a plentiful and easily accessible water resource. Gr...

The alluvial plain of Sarvestan bears the sole source of potable water in Sarvestan county, Fars Province, Iran. In recent years, due to extended heavy pumping, the groundwater storage has been reduced continuously. The UNGWM (United Nation Ground Water Model) is used to evaluate the hydraulic characteristics of the Sarvestan aquifer and its future response to various regimes of recharge and di...

Crystalline aquifers of semi-arid southern India represent a vital water resource for farming communities. A field study is described that characterizes the hydrodynamic functioning of intensively exploited crystalline aquifers at local scale based on detailed well monitoring during one hydrological year. The main results show large water-table fluctuations caused by monsoon recharge and pumpin...

In India, electric utilities are owned and operated by the government. This paper explores whether these utilities have functioned to maximize social welfare and whether electricity pricing, through the provision of agricultural subsidies, has been manipulated for political purposes. We first explore the benefits of electricity subsidies to the agricultural sector between 1995 and 2004. A simpl...

The integration of the Strapdown Inertial Navigation System and Global Navigation Satellite System (SINS/GNSS) has been implemented for land-based gravimetry and has been proven to perform well in estimating gravity. Based on the mGal-level gravimetry results, this research aims to construct and develop a land-based SINS/GNSS gravimetry device containing a navigation-grade Inertial Measurement ...

B Alluvial aquifers are largely used as groundwater resource since large flow rates can be obtained due to infiltration from the neighboring river. Reductive conditions in the infiltration flow path, caused by the...

While the sustainability of resource depletion is a longstanding environmental concern, wider attention has recently been given to growing water scarcity and groundwater depletion. This study seeks to test the substitutability assumption embedded in weak sustainability indicators using a case study of Californian water supply. The volume of groundwater depletion is used as a proxy for unsustain...

Understanding runoff generation and dynamics is the basis for water resource management, while water isotopic ratios are a potential tool for studying the mechanism on a large scale. In this paper, spatial variations of δ18O and δD of river water and their sources within a large region of the Tarim River were investigated. The results showed obvious spatial variations of both water isotope valu...

anthropogenic alterations have affected urban hydrology in india and have generated a wide range of hydrological problems. such alterations include increase in directly-connected impervious cover thus reducing natural groundwater recharge. in the past urban runoff was largely viewed as a nuisance, but within the new paradigm of sustainability, this water is recognized as a potential resource. t...
