Answer and Explanation: Vegetation has a tremendous influence of preventing sediment loss by holding the soil together and dampening effects of weather. In vegetation type surfaces, the infiltration rate is higher because the leaves, branches, petals, and roots have the power to hold the water and prevent it from directly hitting the ground. How Does Sediment Affect the Ecosystem? Living and decaying roots create a network of well connected channels in the soil called macro pores. 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.

Data from Part I also show that the evaporation rate is at 30%. In these cases, the water table, below which the soil is saturated and possibly able to yield enough water that can be pumped to the surface, can be lowered by the excessive pumping.
