A special issue of International Journal of Water
Water is vital for all of us. We depend on its good quality - and quantity - for drinking, recreation, use in industry and growing crops. It also is vital to sustaining the natural systems on and under the earth's surface. Groundwater is a hidden resource. At one time, its purity and availability were taken for granted. Now contamination and availability are serious issues.
One of the most commonly used forms of groundwater comes from unconfined shallow water table aquifers. These aquifers are major sources of drinking and irrigation water. They also interact closely with streams, sometimes flowing (discharging) water into a stream or lake and sometimes receiving water from the stream or lake.
An unconfined aquifer that feeds streams is said to provide the stream's base flow. In fact, groundwater can be responsible for maintaining the hydrologic balance of surface streams, springs, lakes, wetlands and marshes. This is why successful watershed partnerships with a special interest in a particular stream, lake or other surface water body always have a special interest in the unconfined aquifer, adjacent to the water body.
The source of groundwater (recharge) is through precipitation or surface water that percolates downward. Approximately 5-50% (depending on climate, land use, soil type, geology and many other factors) of annual precipitation results in groundwater recharge. In some areas, streams literally recharge the aquifer through stream bed infiltration, called losing streams. Left untouched, groundwater naturally arrives at a balance, discharging and recharging depending on hydrologic conditions.
The aim of this special issue is to preserve, enhance, and restore water quality through a comprehensive understanding of the hydrologic cycle, with particular focus on collaborative engagement between surface water and groundwater researchers, facilitating an increased knowledge of surface water and groundwater interaction.
