Guidelines for the Assessment of Groundwater Extraction Effects on Stream Flow - 2001

This technical guideline has been prepared to help the recognition of situations where significant stream depletion effects may occur and to provide tools that quantify the effects of groundwater abstraction on surface waterways. These tools apply to the assessment of single pumping wells, or small groups of wells by using the superposition of single well effects. The cumulative effects of large numbers of wells
is best dealt with through the preparation of regional groundwater flow models, which is beyond the scope of this guideline document.
