The natural factors that influence infiltration rate include soil characteristics, plant and animals, and topography. Man can modify these features to highly influence runoff. For instance, areas with grass/vegetation will reduce runoff by reducing speed of water on surface hence increasing percolation chances. On the other hand, bare lands will offer less resistance to water hence faster runoffs. In the event that rainfall produces much water to the land surface than it can be absorbed by the soil, the excess water will be left on the surface to flow down slopes as runoff. Wet areas with higher vegetation covers can have higher water tables that lead to faster saturations hence runoff. On soil characteristics, finer soils will reduce infiltration and increase runoff and vice versa. Still, the size of rain drops can help compact soil reducing runoff. Concerning plant cover, they increase infiltration rates in that they slow the pace of water falling to surface and reduce chances of faster runoff. Areas that lack vegetation are subject to flash floods whenever high precipitation takes place. In an incidence when there is a steep slop at headwaters, then more runoff is apparent. All this water will eventually reach the...
If the runoff is much, it means much water will reach the streams hence higher chances of flooding, if runoff is less, less water reaches streams hence less potential for floods. Remember the rate of runoff is a factor of topography where steep slopes have faster flows compared to gradual slopes.
It was then important to see the degree at which technology and training played a role in combating each fire. 1.2.4.Rationale of the Study What is that can be gained from this study? The reasoning behind such a study is born out of a need to provide better training for fire fighters so that fire management systems will improve and reduce the amount of loss due to the fire. By studying
Stream Degradation and King County' Salmon Population King County in Washington State is home to some of the most significant spawning beds in the nation for several major species of salmon, such as the endangered steelhead and Chinook (or King) species. As a result of Washington's urbanization over the preceding years and decades, the purity and integrity of King County's streams and rivers have been degraded and the waterways contaminated (Morley,
Certain traits must be present for any attempt at a shift in use of resources to work. First, the new use must hold the potential for greater income than what the people were doing. There must be some incentive for them to learn new skills First, such attempts must promise better returns than the alternative practice and second, they need to be evaluated for how they fit into the set of
His analysis is therefore a direct investigation of the contact between the two cultural identities and their specific characteristics. As opposed to this, Cronon uses an indirect argumentation to demonstrate the differences between the two cultures. He starts his discussion from a critique of Thoreau's view on the origins of the American civilization. Thoreau first advocated that the American land was a virgin territory when it was in the hands
Pastorilism The way humans eat affects the globe in many ways. The balanced ecosystem requires a homeostatic process that achieves cooperation and will allow the environment to thrive. It is possible that humanity may very well eat its way into extinction if certain practices are not curtailed. Smil (2013) wrote " this increased demand was met by a combination of expanded traditional meat production in mixed farming operations (above all
Loans needed to buy the equipment and seeds create indebtedness to Western banks. Western professionals are needed to intervene and to manage. The productivity of monocrops (e.g., rice or maize) undermines other native crops. Routledge writes, "The project destabilized traditional farming methods, which further rationalized the use of new technologies from the West, and the displacement of traditional foodstuffs by the HYVs" (316). The whole agro-food system has damaged
