The surface run off is likely to be greatest on a sloped area (30 deg-45deg) where we have least forest cover or an area where deforestation has occurred during heavy rainfall. This sloped area could be of an hill or edging flanks of a plateau........
Surface runoff will likely be greatest in urban areas with large amounts of impervious surfaces like concrete and asphalt, as these surfaces prevent water from infiltrating into the ground. Additionally, areas with steep slopes and compacted soils are also prone to high surface runoff during heavy rainfall events.

Runoff
Rainfall refers to the precipitation of water droplets from the atmosphere to the ground. Runoff, on the other hand, is the movement of excess water on the ground surface due to factors like saturation or impermeable surfaces. Essentially, runoff is the flow of water that occurs after rainfall.
Urban areas typically have the greatest amount of surface runoff due to extensive impervious surfaces like asphalt and concrete, which prevent water from infiltrating into the ground. This leads to increased runoff during precipitation events, contributing to flooding and pollution of waterways.

Runoff and rainfall are closely related hydrological processes. When rainfall occurs, some of the water infiltrates the ground, while the excess flows over the surface as runoff, especially in areas where the soil is saturated or impermeable. The amount of runoff generated depends on factors such as the intensity and duration of rainfall, land use, and soil characteristics. In general, higher rainfall amounts can lead to increased runoff, particularly in urbanized or deforested areas.
In areas where there is no snow, runoff will come from rainfall. However, not all rainfall will produce runoff because storage from soils can absorb light showers. Infiltration excess overland flow more commonly occurs in arid and semi-arid regions, where rainfall intensities are high and the soil infiltration capacity is reduced because of surface sealing, or in paved areas. When the soil is saturated and the depression storage filled, and rain continues to fall, the rainfall will immediately produce surface runoff. Urbanization increases surface runoff, by creating more impervious surfaces such as pavement and buildings, that do not allow percolation of the water down through the soil to the aquifier.
Runoff is water that cannot soak into the ground and instead flows across Earth's surface
That is called runoff, which occurs when water flows over the ground surface instead of infiltrating into the soil. Runoff can be generated by rainfall, snowmelt, or irrigation.
