Research Perspectives in Hydraulics and Water Resources Engineering

Rama Prasad, S. Vedula9789810249298, 981-02-4929-2

This book contains ten state-of-the-art review articles on selected topics in hydraulics/fluid mechanics and water resources engineering, written by alumni of the Indian Institute of Science who hold senior academic positions in reputable scientific institutions and who are active in research. The articles have all been peer-reviewed. At the end of each contribution, a rich list of references is given, encompassing most of the work done all over the world on the topic of the article. The topics are of current interest to research workers in many countries.
Contents: Turbulent Jets: Application of Point Source Concept (B S Pani & S B Dugad); Velocity and Shear Distributions in Open Channels (K V N Sarma & B V R Prasad); Computation of Open-Channel Flows with Shocks: An Overview (S M Bhallamudi); Scouring Horseshoe Vortex (T Gangadharaiah et al.); Wastewater Renovation Using Soil-Aquifer Treatment System (C S P Ojha); Uncertainty Concepts in Stream Water Quality Management Models (P P Mujumdar); Water Resources and Their Management for Sustainable Agricultural Production in India (P B S Sarma); Remote Sensing Applications to Water Resources (D N Kumar); Modeling Reservoir Operation for Irrigation (S Vedula); Opposition to Large Dams in India: An Analysis (R Prasad).
