WebContour lines form a V-shape on the map, pointing upstream. By counting the number of lines that cross a certain segment of a stream, multiplying this by the contour interval, and dividing that quantity by the length of the stream segment, one obtains an approximation to the stream gradient. Web22 mrt. 2024 · Water balance is expressed as: P = Q + E (+/- change in storage) where P = precipitation Q = run-off E = evapotranspiration Rivers will always have a regime which they follow, in that some months the discharge of the river will be higher than others.
Web1. 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.
