Basin area, basin length, basin slope, and basin shape are the physical characteristics of watersheds, significantly affecting the characteristics of runoff and other hydrologic processes.
WebJan 15, 2024 · Does runoff increases as slope increases? Results show that runoff increased as slope gradient (ranging from 2.45 to 6.43 mm) reaching the critical point of 25% for slope, then runoff decreased with an increasing slope gradient from 25% to 40%. Which has more run off a steep slope or a gentle slope? Webvolume of runoff, while the expected increase in the peak flow for the local 100-yr event was only 26% for the same site. Although any increase in severe flooding is problematic and cause for concern, the much larger increase in annual runoff volume, and associated decrease in groundwater recharge, likely has a much greater effect on in-stream
