| dc.description.abstract | The development of the groundwater resources, understanding and knowledge of hydrology and hydrogeology systems is very crucial. For sustainable use of water resource, well documented groundwater level observations are needed to derive recharge rates and sustainable withdrawal amounts. Understanding the groundwater Evaporation, the amount of recharge and withdrawals is important for sustainable water use and effective management of groundwater resources. Although groundwater is routinely monitored in most of the world, relatively little information is available in Ethiopian highlands where groundwater irrigation could greatly increase food security. To obtain shallow groundwater monthly variation on the flood plain, I measured the Kunzila zuria plain groundwater levels were 38 hands dug wells and two deep wells over a 1year dry period in 2017 October to 2018 June. The groundwater table and flow of the plain predicted by geostatistical analysis ordinary kriging methods and surfers golden software using the inputs of measured shallow groundwater tables, also hydraulic conductivity and soil textures of the plain determined in situ and soil labs to selected five points near to Wdeh-5, West-1, Wlat-1, Wlat-7 and Wljo-2 in the study area to representatives it’s. The amount of water contributed to Lake Tana during the dry season from the aquifer were 77,818 m3/ year the groundwater flowed of the plain was slowly towards the lake by the gradient of 0.23%, but water passing the lakeshore was not a significant term in the water balance of the plain. At the end of the dry monsoon phase in June, the average groundwater table was at 5.92 m depth and the amount of water removed by evaporation during the dry phase was 737.2 mm. This is replenished through recharge during the wet phase of moisture in the soil water system and recharge to ground water so rainfall is the principal means for replenishment. | en_US |
