Scarcity of in-situ observations coupled with high orographic influences has prevented a comprehensive assessment of precipitation distribution in the high-altitude catchments of Indus basin. Available data are generally fragmented and scattered with different organizations and mostly cover the valleys. Here, we combine most of the available station data with the indirect precipitation estimate...

A multidisciplinary study involving lithofacies analysis, palynofacies, and palynology is presented for the Muarádzi Sub-basin. This sub-basin part of Moatize-Minjova Basin (MMB), an important Karoo aged coalfield in Mozambique. total 99 core samples from 3 coal exploration boreholes (DW11, DW21, DW141) were analysed all successions assigned a Lopingian age based on palynology. According to dat...

The paper evaluated the potential of groundwater pollution in the Densu River Basin of Ghana. Groundwater is an important resource in this basin currently supporting domestic, agricultural and industrial activities. The significance of water resources and the potential for groundwater quality to deteriorate due various anthropogenic activities within the Densu River Basin has necessitated this ...

The supply and demand of ecosystem services their mutual feedback are important for the formulation basin ecological environmental policies. Simulation spatial flow can clarify division areas support policy development. This paper takes Jinghe Basin in Loess Plateau China as case-study area to simulate soil conservation service on different scales. results showed that (1) erosion situations imp...

Soil conservation and control of erosion is a basic problem in all countries. The goal of this research is to estimate erosion and sediment yield in Ekbatan Dam drainage basin by Erosion Potential Method (EPM), using Geographic Information System (GIS). The basin is located in Hamedan Province, west of Iran, in a cold and semi- arid region, with an average annual rainfall of 334mm. The study ar...

The process of precipitation – runoff of each basin, is influenced by hydrologic, geomorphology conditions, geological formation and vegetation. There are different methods in drainage basins. One way to estimate the runoff height is Curve Number (CN) method. That reperesents the hydrological behavior of basin. data were collected for statistics of climate and then topographic map of 1: 25000 a...

The European Water Framework Directive (WFD) introduced an integrated perspective in water resources management, based on an approach where the river basin is the management unit and the active involvement of all affected parties by its river basin management plan is clearly encouraged. The integrated perspective is required to develop sustainable resource management strategies adapted to the i...

Large-scale changes in land use are occurring in many tropical regions, with significant impacts on nitrogen and phosphorus biogeochemistry. In this study we examine the relationships between land use, anthropogenic nutrient inputs, and riverine nutrient exports in a major agricultural watershed of the Pacific coast of South America, the Guayas River basin of Ecuador. We present comprehensive n...
