Description Suspended solids, H,chlorides, DO, BOD, PO3-d4 -P, NO3- -N and NH+d4 -N were estimated at 12 stations along a 70 km stretch from the mouth of the river Narmada during March, May, June and August 1979. Tidal range of over 1 m observed at a point 52 km upstream was due to the piling up of fresh water, and some intrusion of sea water occurred at 44 km upstream in early June when riverine flow had decreased considerably. Significant penetration of saline water was observed only up to 20 km during March. The water column was well mixed vertically with the absence of any significant stratification. High H of fresh water influenced the H of the estuarine region which varied considerably over tidal cycles. The estuarine zone was characterized by high, tide dependant, suspended load which decreased appreciably in fresh water region. High overall DO and low BOD indicated the absence of gross organic pollution in the estuarine and riverine zones. NO3u- -N decreased in the downstream direction while PO3d4- -P showed an increase; NH+d4 -N concentration indicated natural background levels
