Land Use/Land Cover Changes and Groundwater Potential Zoning in and around Raniganj coal mining area, Bardhaman District, West Bengal - A GIS and Remote Sensing Approach
Land Use Land Cover Groundwater Zoning
2015/8/6
The Raniganj area has a long history of coal mining starting from 1744. This has resulted in major change in land use pattern and high groundwater abstraction leading to drinking water crisis especial...
Changes in runoff regime. The Lomnice catchment case study
Bilan model hydrological regime mass curve method water balance
2015/3/13
Water distribution in landscape is essentially influenced by the nature of the catchment rainfall-runoff process. Firstly, this paper presents an analysis of trends in the rainfall-runoff regime of th...
Annual changes in the chemical composition of stream water in small catchments with different land-use (Carpathian Foothills, Poland)
river water chemistry water pollution nutrient compounds flow tendency
2015/2/4
The aim of the study was to identify the factors that influence annual changes in the chemical composition of stream waters. The research area was located in the marginal zone of the Carpathian Foothi...

Changes in streamflow and sediment discharge and the response to human activities in the middle reaches of the Yellow River
Changes in streamflow sediment discharge
2011/1/7
The changes in streamflow and sediment discharge in the middle reaches of the Yellow River are a focus. In this paper, based on the precipitation, streamflow and sediment discharge series data (1950–2...
Streamflow sensitivity to climate and land cover changes: Meki River, Ethiopia
climate land cover changes
2010/12/22
Impacts of climate and land cover changes on streamflow were assessed using a hydrological modeling. The precipitation runoff modeling system of the US Geological Survey was modified in order to consi...
A Finite Element Aquifer Model which takes into Account Elevation Changes of the Aquifer
Finite Element Aquifer Model Elevation Changes Aquifer
2009/10/29
A finite element formulation for confined aquifer flow, which takes into
account elevation changes of the aquifer is presented. The middle surface of
the aquifer is assumed not as a horizontal plane...
Changes in the Flexural Strength of Ice under Radiation Decay
Flexural Strength Ice under Radiation Decay
2009/10/26
The strength of an ice cover significantly affects the timing and severity of
breakup on northern rivers. During the pre-breakup period, thermal and radiative
warming is known to significantly decre...
Difficulties in Deducing Temporal Changes in Precipitation Chemistry from Snow and Ice Cores:The Spatial Variability Problem
Temporal Changes Precipitation Chemistry Snow and Ice Cores Spatial Variability Problem
2009/10/26
Depth profiles of chemical impurities found in snow and ice have usually been
interpreted simply in terms of temporal changes in atmospheric concentrations
of the species of interest. Measurements o...

Streamflow Simulation Climatic Inputs
2009/10/26
Sensitivity of streamflow simulations to changes in temperature and precipitation
were evaluated for a small basin (A - 53 km2) characterized by low
evapotranspiration and high conversion of precipi...
Changes of Ionic and Oxygen Isotopic Composition of the Snowpack at the Glacier Austre Okstindbreen,Norway,1995
