    <subfield code="a">&lt;p&gt;Water used for different purposes is harvested in the watershed system; largely in the river&lt;br&gt;
basin system. To maintain the requirement of these purposes, both quantity and quality of&lt;br&gt;
water for ecological, social and economical development could be manage appropriately&lt;br&gt;
through integrated water resource management. However, scarcity and poor water quality are&lt;br&gt;
the major challenges of the world due to climate change and water pollutions. These&lt;br&gt;
challenges trigger further ecological, economical and public health impacts. In Ethiopia,&lt;br&gt;
evidence shows that upper Awash River sub-basin is the most impacted river basin that is why&lt;br&gt;
protection of both groundwater and surface water resources come to an essential approach&lt;br&gt;
through investigation of hazards, vulnerability and consequences of the water sources. This&lt;br&gt;
research is designed to identify vulnerable and risk of ground water pollutions so as to indicate&lt;br&gt;
the requirements of protection of vulnerable aquifer considering seven important factors of&lt;br&gt;
groundwater vulnerability as well as land use management. To achieve these objectives,&lt;br&gt;
digitized data for parameters and secondary data from concerned sectors have been collected.&lt;br&gt;
These collected data and Shape files have been analyzed using ArcGIS 10.2 software and&lt;br&gt;
SPSS version 24. Sensitive analysis, model validation, vulnerability index and risk index have&lt;br&gt;
been produced&lt;/p&gt;</subfield>
