2 Why Do We Study Water Resources Management? -2

3 Water resources management Water resources management can be defined as a process that secures enough water of suitable quality to meet demand at all times, if this demand is reasonable and that there is no waste of water. More broadly, water resources management is an integral part of water governance, which refers to the range of political, social, economic, and administrative systems that are in place to develop and manage water resources, and the delivery of water services, at different levels of society (Rogers and Hall, 2003). Groundwater management is commonly divided into supplyside management and demand-side management. This division is more for technical and administrative purposes, however, since the two aspects are interdependent.

4 Groundwater is an essential element of the overall hydrologic cycle. It is inseparable from surface water resources because it provides baseflow and sustains aquatic life in surface water streams, lakes, and wetlands, as well as in the aquifer itself (such as in karst caves and conduits) The largest sources of fresh water lies under the Earth surface (groundwater) The groundwater resources has greater advantages over the surface water

5 Maximum development of groundwater resources for beneficial use involves planning and management of an entire groundwater basin (aquifers) For the good groundwater management we must know the groundwater flow movement, pollution control, water wells drilling and design, modeling, techniques for managing groundwater. In other words, we must understand the operation of groundwater basin.

6 Integrated Groundwater Resources Management -6

7 Course Objective: The course presents the fundamentals of groundwater hydrology since it forms the essential water resources in semiarid regions. The management of groundwater resource requires understanding of groundwater occurrence, groundwater movement, well hydraulics, well design, groundwater quality, and groundwater modeling. The course will give the environmental engineers the required tools and techniques for effective groundwater resources management. -7
