Simulation of groundwater recharge from an aquifer storage recovery well under shallow water-table condition

A finite-element groundwater flow model, HYDRUS 2D, was used to simulate drawup and drawdown of piezometric pressure heads in the aquifer storage recovery cycles of varying buffer storage volumes and residence times in a highly brackish, semi-confined aquifer under shallow water-table condition.

Kosi embankment breach in Nepal: Need for a paradigm shift in responding to floods

The breach of the Kosi embankment in Nepal in August 2008 marked the failure of conventional ways of controlling floods. After discussing the physical characteristics of the Kosi River and the Kosi barrage project, this paper suggests that the high sediment content of the Kosi River implies a major risk …

Groundwater quality in the lower Varuna river basin, Varanasi district, Uttar Pradesh

The lower Varuna River basin in Varanasi district situated in the central Ganga plain is a highly productive agricultural area, and is also one of the fast growing urban areas in India. The agricultural and urbanization activities have a lot of impact on the groundwater quality of the study area. …

The importance of regulating transboundary groundwater aquifers

If the United States Supreme Court grants certiorari in a case between Mississippi and Tenessee, the court will have its first opportunity to determine if and how transboundary aquifers should be regulated. The applications of this case are far from surface level. Regulated groundwater allocation would protect environmental and economic …

RaPoPb isotope systematics in waters of Sambhar Salt Lake, Rajasthan (India): geochemical characterization

The Sambhar Salt Lake hydrological system, including river waters, groundwaters, evaporating pans and sub-surface brines, has been analyzed for the salt content (TDS) and naturally occurring radionuclides (210Po, 210Pb and 226,228Ra). The abundance of these radionuclides and their activity ratios show a wide variation in different hydrological regimes, which helps …

Indus Basin water resources

In this article the author advocates demand management for optimal adaptation to changes in water resources in the Indus Basin resulting from climate change.

Effects of hydraulic structures on changing flood zones in Kan river, Iran

Application of hydraulic structures may control the destruction rate of the flood but sometimes they have undesirable effects on some aspects of flood behaviours leading to detrimental outcomes. In the present study, an attempt has been made to investigate the effects of bridges, culverts, groins and drops on inundation extension …

Suyya - A great medieval hydraulic engineer of Kashmir

Pandit Kalhan's 12th century text, the 'Rajatarangini' (composed around 1148-1150 AD), which chronicles the history of Kashmir, describes a well conceived and maintained irrigation system. One of the most notable names recorded in the 'Rajatarangini' is Suyya. He is credited with "draining the water of the Vitasta River and controlling …

Factor analysis of hydrochemical data of Kumadvathi river sub-basin in Karnataka, India

Statistical factor analysis (FA) technique has been applied to chemical data of 125 bore well water samples from Kumadvathi river sub-basin to assess the un-usefulness of such techniques for interpretation of the hydro-chemical data. FA technique identified three factors, which account for 60% of the major ion variations observed in …

Assessment of peak maximum rainfall for estimation of peak flood for ungauged Lakya catchment - A case study

In water resources planning and management many problems are faced in estimation of flood flows in ungauged catchments. Researchers have been adopting different techniques in estimating flows from ungauged catchments for design and risk analysis of hydraulic structures. The important aspect in such situations is an assessment of Peak Maximum …

Predicting and mitigating the impacts of urbanization in a Himalayan catchment through catchment sensitive planning using topmodel, case study: Shimla

Emphasis has been laid since long on the need for integrated catchment management and impactof landuse on catchment hydrology; but the two disciplines have not been amalgmated for creating catchment sensitive 'City Landuse plans'. This study aims at (a) utilizing hydrological modeling to understand the dynamics of an urban Himalayan …
