A Geographical Information System (GIS) based method is proposed and demonstrated for the identification of sediment source and sink areas and the prediction of sediment yield from watersheds. Data from the Haharo sub-catchment having an area of 565 km<Superscript>2</Superscript> in the Upper Damodar Valley in Jharkhand...</superscript>

A GIS-based method has been applied for the determination of soil erosion and sediment yield in a small watershed in Mun River basin, Thailand. The method involves spatial disintegration of the catchment into homogenous grid cells to capture the catchment heterogeneity. The gross soil erosion in...

This study introduces a continuous simulation model dealing with the reconnaissance estimation of sediment yield from a hydrological basin. Based on this model, historical precipitation data of the Mornos River Basin in western Greece, were analyzed. The analysis allowed to establish a...

Rainfall has a considerable role in soil erosion and can be used to determine the rate of soil erosion at different areas. In general, the erosivity factor is represented by erosivity indices that are based on rainfall characteristics and drastically varies from place to place. However,...

Modeling efforts on Nestos river are presented. First, the Soil and Water Assessment Tool (SWAT), within a GIS interface (version AVSWATX), was applied to the lower Nestos River basin in Northern Greece. The model was calibrated and verified with the use of field data collected at four...

Border areas comprise inevitably problematic fields especially when the countries are bound to share common water resources. The conflict potential is rather high and quite often countries are directed to the negotiation table in order to form tranboundary agreements. These agreements aim to the...

The lagoons of N.E. Greece, located on the western side of NestosRiver, and of N.W. Greece, located at the lower reaches of Kalamas River, are among the most important shallow, semi-enclosed ecosystems in Northern Greece. The temporal variability of nutrients at both lagoonal systems shows the...

Estimation of uncertainty using agronomic models typically requires a Monte Carlo study with a large number of simulations. Parallel computation dramatically speeds repetitive computation of this sort. The use of a Beowulf cluster parallel computer offers a low cost method of parallel computing...

In Jakarta, climate change has been detected through rising air temperatures, increased intensity of rainfall in the wet season, and sea level rise. The coupling of such changes with local anthropogenic driven modifications in the environmental setting could contribute to an increased...
