ASSESSMENT OF RIVER BANK FILTRATION POTENTIAL AT RIVERS GANGA AND INN

Abstract

In this thesis the main emphasis is on the evaluation of the riverbank filtration potential for the rivers Ganga and Inn using the software Pmwin. Regarding how the process of riverbank filtration works is described in general in the first chapter, and the corresponding governing equations, on which the software is based is described in chapter 2. Hence for the evaluation of the riverbank filtration potential, the software pmwin was used which is a freeware version 5.3, and which is also easily available on the net. The RBF potential for the different riverbank filtration sites in Austria and India were evaluated using the above mentioned software and corresponding calibration was done for both the models as explained in the chapters 3 & 4.AIso a time drawdown analysis was performed on well no "18" at Haridwar, India for estimation of the aquifer parameters. Similarly software named RAMA was developed, with the help of which we could obtain the output files for river conductance, river concentration, river stage elevation & river bed elevation respectively and as a result of which the analysis of a river section becomes comparatively easier. Finally the results of the RBF potentials for both the sites and for different conditions are presented in chapter 4, followed by conclusions and the further scope of study that is required with regards to the potential of riverbank filtration.
