WebMar 2, 2024 · 5. Factors affecting Hydrograph a. Shape of Basin. In the fan-shaped basin, the time taken for water to reach the outlet from remote parts is almost similar. so, it is distributed over a short time and has a high peak. In the elongated basins, the time taken to reach output from remote parts is different. WebThe main factors affecting hydrograph shape are: 1) Drainage characteristics: basin area, basin shape, basin slope, soil type and land use, drainage density, and drainage network topology. Most changes in land use tend to increase the amount of runoff for a given storm (e.g., Chow et al., 1988; Singh, 1989; Bras, .1990). WebWhat factors influence the shape of a hydrograph?
