Freshwater resources and healthy coast lines are the basis of ecotourism in the Caribbean islands. The vulnerability of these islands to natural and human-induced disasters and their inability to cope with the problem necessitate the understanding of the hydrological processes and responses of the watersheds to various stressors. The main objective of this study is to characterize, model and analyze...
Soil water infiltration is one of the most important processes affecting the volume, transport route and water quality of agricultural drainage. Tillage method and depth have also effects on the ability of soil to store water and the furrow irrigation hydraulics of irrigated fields. A study was conducted to evaluate the effect of tillage method and depth on furrow irrigation hydraulics and soil water...
Awash River Basin is one of the twelve basins of Ethiopia which is highly utilized and the first basin to be introduced to modern agriculture. A study was conducted on water allocation modeling of Awash River Basin, Ethiopia, using MODSIM, a river basin management decision support system (DSS) designed as a computer-aided tool for developing improved basin wide planning. This study was conducted to...
Tillage practices and depth of plow play an important role in altering the porosity and infiltration capacity of soils and hence surface runoff and soil water availability. A study was conducted to evaluate the effect of tillage method and depth on grain yield and irrigation water use efficiency (IWUE) during the dry season at Dire Dawa, eastern Ethiopia. Treatments for this study included were chisel...
The provincial wetland (“status quo”) maps of the Prairie Pothole Region, Central Canada, do not adequately depict wetland resources and properties. Using satellite remote sensing data from both LANDSAT Enhanced Thematic Mapper Plus (ETM+) and RADARSAT-1 Synthetic Aperture Radar (SAR) results in a more complete picture, although using both sources together is better than when either source is used...
Information on suspended sediment load is crucial to water management and environmental protection. Suspended sediment loads for three major rivers (Mississippi, Missouri and Rio Grande) in USA are estimated using artificial neural network (ANN) modeling approach. A multilayer perceptron (MLP) ANN with an error back propagation algorithm, using historical daily and weekly hydroclimatological data...
