Effects of surface runoff Erosion and deposition. Surface runoff can cause erosion of the Earth's surface; eroded material may be deposited a considerable distance away. There are four main types of soil erosion by water: splash erosion, sheet erosion, rill erosion and gully erosion. Splash erosion is the result of mechanical collision of ...
Oct 19, 2023 · Runoff is when water flows across the land and into waterways. It can be natural or human-made, and it can cause pollution and harm ecosystems.

Mar 22, 2021 · This can happen in two ways: Prolonged rainfall – moderate to high volumes of rainfall over a sustained period can eventually saturate the soil leading to runoff. Intense rainfall – heavy rain in a short period can bounce and then flow over the Earth’s surface as runoff. Vegetation cover. Vegetation can intercept precipitation and reduce ...
CHAPTER 8: Introduction to the Hydrosphere. (n). Introduction to Surface Runoff. If the amount of water falling on the ground is greater than the infiltration rate of the surface, runoff or overland flow will occur. Runoff specifically refers to the water leaving an area of drainage and flowing across the land surface to points of lower elevation.
Feb 26, 2019 · Surface runoff, or overland flow, is a fundamental process of interest in hydrology. Surface runoff generation can occur at multiple scales, ranging from small pools of excess water that propagate downhill to stream networks that drain large catchments. Accurate quantification of runoff is vital to clarify the mechanisms and effects of overland ...
