Into a stream, with no trace of salt initially, a salt with a concentration of 20 mg/cc is introduced at a constant rate of 2 litres per minute. The samples collected at a downstream section sufficiently far away indicated an equilibrium salt concentration of 0.05 ppm. Determine the discharge in the stream from this data.

The following data pertain to streamflow in a river at a given gauge station. The rate of rise in water surface elevation = 10.0 cm/h. the normal discharge for the river stage obtained from the steady flow rating curve = 150 m3/s. slope of the river bed = 3 x 10-4. Assume the velocity of the flood wave to be 2.5 cm/sec, compute the river discharge.

A drainage basin has an area of 210 km2. The average depth of rainfall received by it during a monsoon period is computed as 65 cm, while the runoff measured at its outlet during the same period is estimated to be 5.68 x 107 m3. Compute the depth of runoff. What percentage of rainfall has become runoff? If all this runoff volume is stored and used to irrigate a crop which requires 60 cm of water, how many hectares can be irrigated?
