Introduction The Nile River the longest river in the world has been serving as a source of life to the people living in its basin for centuries. Throughout the course of history, the Nile has supported livelihoods and played a considerable role in enriching diverse cultures within its basin. Hence, the Nile has been the centre of attention of explorers, tourists, researchers and historians for ...

MODSIM 8.0 is a generic river basin management decision support system for analysis of long term planning, medium term management, and short term operations on desktop computers operating under MS Windows 2000/XP. MODSIM is free from expensive licenses for proprietary software since all components are developed from native code or shareware under the MS .NET Framework. MODSIM includes a powerfu...

correct estimates of the risk of erosion at improve land management advice plays an important role. in this study, erosion risk zoning in the kan basin with area about 20571 ha in the northwest of tehran by using the experimental model mpsiac and geographic information system (gis) were investigated and by using the base maps and gis, layers of information were prepared. after collecting, prepa...

The Great Lakes-St. Lawrence River basin community is challenged in achieving a basin that thrives ecologically, economically and socially. Although natural science, social science, policy, and law literatures offer insight into understanding and developing policies for the Great Lakes-St. Lawrence River basin, these literatures are constructed in disciplinary silos. Scenario analysis supports ...

Large-area hydrologic modelling can play an important role in policy planning related to water and land management issues. Models are often required to assess the impacts and risks of management alternatives on the availability and quality of water in large and complex river systems. This paper describes the Hydrologic Unit Model for the United States (HUMUS): a decision support system designed...

The lunar semidiurnal influence is already known for tidal rivers. The moon also influences inland rivers at a monthly scale through precipitation. We show that, for some non-tidal rivers, with special geological conditions, the lunar semidiurnal tidal oscillation can be detected. The moon has semidiurnal tidal influence on groundwater, which will then export it to streamflow. Long time series ...

East Asian summer monsoon (EASM) precipitation received by northern China over the past 800 thousand years (ky) is characterized by dominant 100-ky periodicity, mainly attributed to CO2 and Northern Hemisphere insolation-driven ice sheet forcing. We established an EASM record in the Late Miocene from lacustrine sediments in the Qaidam Basin, northern China, which appears to exhibit a dominant 1...
