Mathematical model of Fast High Volume Infiltration into subsurface

Managing fresh water resources has become critical worldwide. Large areas on earth are already dealing with the problems of water shortage and extreme periods of drought and rainfall. Storage of water into groundwater aquifers, which is available during excess supply, can be considered to be an efficient solution to this problem. Fast high volume infiltration (FHVI) is a technique to inject high volume of water into subsurface in a short span of time. During periods of heavy rainfall or dewatering of sites of construction large volume of water is available which can effectively be used in future if stored. Storage in groundwater aquifers has huge benefits but the conventional infiltration techniques cannot achieve FHVI. The present study tries to model models the FHVI process mathematically. The model results are compared with that of a numerical model and also an experimental field study.
