Rational Method: In this method, the peak rate of runoff is given by the equation-. Runoff coefficient C is defined as the ratio of the peak runoff rate to the rainfall intensity. Values of C for different slopes and land use conditions, determined from field observations are given in Table 3.2. ADVERTISEMENTS: WebWhat I have done is the past is take a flowline, densify the vertices so there is one every 100 ft or so. Then lines to points and use lineae referencing to get a distance along line for each point. Then extract the Dem value to each point and you have distance and elevation aka x and y for your slope or gradient maths. 2. slowest penguin species
