Research On The Assessment Of The Rainwater Of Utilize Potential And Application Model In Kenya

Kenya is located in East Africa,central trans equatorial,belonging to the tropical monsoon climate.The territory of lakes,numerous rivers,but the amount of water resource is limited,the shortage of water resources very prominent;and at this stage in Kenya's domestic water resources development and utilization of low level and utilization efficiency is low,and the water resource use planning is not comprehensive and other factors influence,that Kenya faces serious water shortage dilemma.As of the shortage of one of the regions of the water resources in the world,the problems of water resources is serious problems of Kenya's economic and social sustainable development one of the main problems.Therefore analysis and study of the potential of rainwater resources in Kenya domestic utilization based on,and puts forward the fit is actually The situation and demand of rainwater utilization mode,to improve the utilization of rainwater resources,to ease the contradiction between water resources shortage and social development is of great significance.So this article mainly through:(1)Select Kenya National 47 county has good representation of 47 rain station as the study of the basic information data and rainfall series data sources,using trend analysis and the method of mathematical statistics and Analysis on distribution of Kenya,the annual mean precipitation area,annual distribution,annual change characteristics of the precipitation,according to the partition principle and method of rainwater utilization,in 2010 as the base year divided rain in Kenya using key areas and rain the general area.(2)Analysis and evaluation on the potential of rainwater utilization in the key areas of the division of rainwater utilization.Through the potential calculation,it is concluded that the potential of rainwater utilization in the key areas of Kenya rainwater utilization can be approximately maintained at to 1.8 m3.(3)In the face hidden great utilization potential,combined with the Kenya domestic actual situation and different needs,the corresponding proposed for rural life water "roof initial abandon flow water storage tank,the roof initial abandon flow cellar water purifier water pump" and "catchment area slope yard/road)+water diversion canal(tube)sedimentation tank water cellar(reservoir)+water pump" three kinds of rainwater utilization mode,small scale agriculture of supplemental irrigation "catchment area(slope/road)+water diversion canal(tube)sedimentation tank reservoir water supply pipe irrigation system" and "artificial catchment surface sedimentation tank reservoir solar pump Field irrigation system" two kinds of rainwater utilization pattern and meet wild animals supplemented with drinking water of "natural catchment area+sink basin+Diversion Canal+reservoir water level+control device and the water trough" and "natural catchment area and pond" two rainwater utilization mode.(4)Through analysis of the expected benefits of Kenya's future implementation of the development of rainwater utilization project,Kenya rainwater utilization can effectively promote to improve the water quality of rural life,agricultural irrigation water source protection and wildlife protection,regional social and economic development and resource environment insurance protection water resources conditions.
