Annual extreme rainfall series of 1-3 day durations at stations located inside the Indus basin in India were subjected to statistical analysis in order to estimate point Probable Maximum Precipitation (PMP) and maximum rainfall of different return periods for the durations of 1-3 days.

Water quality of river Mandakini was assessed from Sati Anusuya to Karwi. Altogether 4 samples were collected from each sampling station and 5 sampling stations were selected for analysis. The quality analysis was made through the estimation of temperature, turbidity, DO, pH, EC, TDS, sodium, potassium, calcium, magnesium, carbonate, bicarbonate, chloride, sulphate, nitrate and phosphate.

Agricultural production from the deltaic regions is the highest in countries like India. Study of groundwater quality, which is a function of physical and chemical parameters of the geological formations, is important as it will affect the agricultural production.
