WebMay 9, 2024 · The size of catchment has a definite effect on the runoff. More the area, more will be the runoff. So also, the shape will have a definite effect on the runoff. In case of a fan-shaped catchment area, the base period of the resulting hydrograph will be less and thus more peak flow may be expected. What factors affect the slope of a slope? WebMar 22, 2024 · A variety of physical & human factors affect runoff (the flow of water over the Earth’s surface). These are summarised below. Physical Factors. Time of year. In temperate climates, where seasonal change is evident, runoff levels can vary greatly throughout the year. In summer, runoff levels can be low due to a reduction in rainfall.

Slope shape effect on runoff and soil erosion under

WebTemperature, wind and humidity also affects the runoff. If the temperature is low and the ground is saturated and frozen, it gives rise to greater runoff. However, if the whole of the stream freezes, the peak floods will be reduced. On the other hand, high temperature and greater velocity give rise to greater evaporation loss and reduce runoff. WebJun 1, 1992 · The results (August 1987 – December 1988) confirm the contrast in runoff and soil losses according to slope orientation (2176 g/m 2 south-facing plot and 352 g/m 2 north-facing plot). This different erosive response is mainly due to: a) the state of the vegetation and soil development before the fire, b) chin s gallery
