Multiobjective Optimization of Multireservoir System
In the present study, a detailed multiobjective nonlinear programming model is formulated and applied to a multireservoir system at upper reaches of Krishna river basin in Karnataka State,...
Applicability of Scour Equations in Tidal Areas
Bridge scour and waterway instability in the coastal region where waterways are subjected to tidal flow can be subjected to mass density stratification, water salinity, sedimentation (littoral...
Alachlor Transport in Laboratory Soil Columns
Spraying of agricultural chemicals result in their travel downward through the unsaturated zone and adsorption to the surrounding soil. Infiltration from rainfall and irrigation solubilize...
Engineering Aspects of Wetland Mitigation
Wetland mitigation demands a multi-disciplinary engineering approach, and a systematic collection, evaluation and analysis of data. The design of a constructed wetland addresses these...
Evaluation of Potential Impacts to Endangered Species that Use Wetland Areas: A Case Study
A proposed runway extension in an airport adjacent to a large riverine system and containing a small perennial branch of the riverine system would result in loss and modification of forested...
