Fresh water is one of Earth’s most important resources and is used extensively for potable water supply, agriculture, industry, and recreation. Yet, at the same time, fresh water is a finite resource. Most is locked up in the polar ice caps and as glaciers and, for this reason, is largely unavailable for use. The remainder consists of groundwater and, to a lesser extent, surface water. Once considered separate entities, groundwater and surface water are now widely viewed as a single resource. This study focuses on the interaction between groundwater and rivers using the concept of transit times.
