In the table below data for precipitation and runoff both in depths of cm are given for June during ten years from 2010 to 2018. Develop a linear equation relating precipitation and runoff.
The annual peak flow data were recorded between 1980 and 2021 at a particular section of a river. Annual peak flows have been transformed into log values and the following statistics are obtained. Mean of log transformed peak annual flows = 3.525 Standard deviation of log transformed peak annual flows = 0.178 Skewness of log transformed peak annual flows = -0.235 a. Estimate the 2% AEP peak discharge by assuming that the annual peak flow data follows Log-Pearson type III distribution. b. Estimate the 2% AEP peak discharge by assuming the peak flow data are lognormally distributed. c. Compare the peak discharge obtained from two methods (l.e. Log-Pearson type III distribution and Lognormal distribution).
Route the following flood hydrograph using Muskingum method through a channel reach for which K = 22 hours and x = 0.25. Plot the inflow and outflow hydrographs on the same graph sheet and determine the peak lag and attenuation from the channel reach. The outflow discharge at t =0 was 40 m°/s.
Recorded flow data from a 7 sq. km. catchment due to a 1 hour rainfall event is given in Table 2. The base flow is 0.14 m³/s. Assume that the uniform rainfall over the catchment area was 39 mm. If the o-index of the catchment area is 21 mm/hr, calculate the ordinates of 1 hour unit hydrograph in Table 2.

Flow rate in a stream discharging water shed runoff is 50 cubic meters per second after five days without rain. The flow rate in the stream reaches half that amount after 20 days without rain. Determine the equation of basal flow hydrograph. Find the amount of flow rate after a period of six months in the watercourse.
