AT - A - STATION HYDRAULIC GEOMETRY OF TARALI RIVER, MAHARASHTRA: AN IMPACT OF HUMAN INTERVENTION ON CHANNEL

The section of Tarali channel for about 4.325 km in direction upstream from its confluence with River Krishna has been studied through field survey carried out in 7 sessions for the present research work. Of the 90 cross - sections, 7 have been selected for the analysis of ‘at - a - station’ conditions from Dec 19 94 and April 19 97 survey session. In the discussions , set of seven scatter plot representing width, depth and velocity conditions for 94 and 97 survey sessions have been considered. The discussion focuses on how hydraulic geometry changes from one location to another location of the channel. Velocity and river discharge at selec ted cross sectional location are calculated using Manning’s formula of the open channel flow. The study also deals with the relationship between the measures of channel form and the proc esses operating in the channel.
