Evaluation of Land Development Impact on a tropical Watershed Hydrology Using Remote Sensing and GIS
Water Resources GIS Remote Sensing
<
2015/1/5
Understanding how the land use change influence the river basin hydrology will enable planners to formulate policies to minimize the undesirable effects of future land use changes. Land cover changes ...
Support Soil Conservation Practices by Identifying Critical Erosion Areas within an American Watershed Using the GIS-AGNPS Model
T value water quality modeling
<
2015/1/5
Eroded soil from overland is one of the major nonpoint pollution sources in many watersheds. The subsequent sediment not only reduces conveyance capacity of streams and usable storage volume of reserv...

<
2015/1/4
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...
Estimating sediment yield using Agricultural Non-Point Sources (AGNPS) model: The effects of slope information from different GIS softwares
Geographical Information System GIS slope information Sediment yield AGNPS model tropical catchment
<
2015/1/4
This study compares the effects of slope information derived from three GIS software on sediment yield as estimated using AGNPS model. The three GIS software are IDRISI for Windows, ERDAS Imagine and ...
Diffused Interface Model to Prevent Ingress of Sea Water in Multi-Layer Coastal Aquifers
Diffused Interface Model Ingress Sea Water Multi-Layer Coastal Aquifers Aquifers water seawater hydrodynamic freshwater intrusion model
<
2015/1/4
In many regions coastal aquifers are major source of supply of water to various sectors. However, indiscriminate pumping from these aquifers leads to seawater intrusion which is difficult to contain. ...
Prediction of Ground Water Vulnerability using an Integrated GIS-based neuro-fuzzy techniques
Geographic Information System GIS Spatial Modeling Remote Sensing Fuzzy Logic Neural Networks
<
2015/1/4
There is a need to develop new modeling techniques that assess ground water vulnerability with less expensive data and which are robust when data are uncertain and incomplete. Incorporation of Geograp...
Spatial Variability of Groundwater Recharge - I. Is it really variable?
Spatial variability Groundwater recharge Sri Lanka
<
2015/1/4
The spatial variability of recharge is an important consideration in estimating recharge especially as all methods of estimating it are 'point' estimates and in most places recharge varies in space. T...
Spatial Variability of Groundwater Recharge - II. Factors Affecting Variability and Taking Account of it in Estimating Recharge
Spatial variability Groundwater recharge Sri Lanka
<
2015/1/4
The accompanying paper provided evidence to suggest that spatial variability of groundwater recharge is ‘true’ variability. This paper attempts to determine the major causes of such variability even a...
