Identification of unknown contaminant source(s) in terms of location and strength in space and time for remediation purposes have been central issues in environmental management.
The study prepares a landuse and landcover map of Devak catchment of Ujh river basin in Jammu for the years 1958, 1979, 1990 and 1998 using image processing and visual interpretation techniques.
The study applies a simple five-parameter model to simulate the daily runoff over a nine-year period of 1989-1997 at Tamavaram in Prakasham district of Andhra Pradesh on the Gundlakamma river.
The study suggests a procedure for estimation of baseflow index using the mean daily discharge data over a period of 4 to 6 years for three rivers between the Mahanadi and Godavari deltas.
