Quantifying Water Quantity and Quality Interactions between Streams and Alluvial Aquifers

 

 

 

Problem Statement:

Conjunctive management of surface water and ground water has become increasingly important as water supply and water quality issues intensify.  However, water law and environmental policies regulate surface water and ground water separately.  Water resource managers are becoming more aware of the importance of the hydrologic connection between surface water and ground water, especially in stream/aquifer systems.  Future water and environmental professionals must possess the capabilities to analyze interconnected hydrologic systems.  Quantifying the degree of interaction between streams and aquifers is important in arid locations for the administration of surface water and ground water rights.  Even in areas with excess precipitation and surface water flow, excessive withdrawals of cleaner, more potable ground water supplies are depleting aquifer storage and nearby surface water reservoirs.  The fate of many rivers, lakes, and wetlands are at the mercy of future economic development and ground water pumping.  Water quality exchange between a stream and aquifer is becoming even more important for developing integrated watershed models capable of simulating all hydrologic pathways of contamination, especially for the development of total maximum daily loads (TMDLs).
