This runoff combines to form channels, rivers and ends up into lakes, seas and oceans. As the roots absorb the excessive water, the overflow is decreased. This means that as the soil is covered by more vegetation, there is likely to be less runoff until the water capacity is achieved, and the surface starts allowing for more water to flow away from the plants. The removal of sediment deposits may be accomplished by a variety of mechanical and hydraulic methods such as excavation, dredging, siphoning, flushing, flood sluicing or by mechanical agitation or blasting of the sediments. How much infiltrates depends greatly on multiple factors. Vegetation contains roots that extend into the soil which create cracks and fissures in the soil, allowing for more rapid infiltration and increased capacity. The absorption rate depends on the moistness of the soil and roots. Vegetation intercepts rain, reducing its energy and preventing splash erosion. Use the following formula to calculate the amount of water after one inch of rainfall (in gallons) for each section: (0.623) x (square feet of surface area) x (% from lab demo*) = gallons of water.

This helps protect soil from erosion and reduces flash flooding. In the bare soil surface type, the runoff amount is 35% since more water infiltrates the soil because it lacks vegetation or nutrients. How does vegetation allow greater infiltration? This runoff. This term can be used in the estimation of water available for downward percolation through drainage, runoff, or returned to the atmosphere by the process of evapotranspiration. Retrieved from http://water.usgs.gov/edu/watercyclerunoff.htmlYong, R. N., Mulligan, C. N. & Fukue, M. (2006). The improved soil structure permitsincreased infiltration. In addition, vegetation can also create roots in the soil which establishes macro-pores that speed up infiltration and take up water. Additional materials, such as the best quotations, synonyms and word definitions to make your writing easier are also offered here. Impervious surfaces, such as parking lots, roads, and developments, act as a "fast lane" for rainfall - right into storm drains that drain directly into streams. How does afforestation help to control landslides?
