Regional approach to estimating groundwater resources.

Research output: Contribution to journalArticlepeer-review


The feasibility of making regional estimates of groundwater resources have been demonstrated in Minnesota. Data from three research approaches were used to estimate groundwater resources: (1) groundwater contribution to the streamflow; (2) 30-day low flow characteristics of Minnesota streams; (3) groundwater hydrographs. Comparison of results of the three methods shows that values derived from groundwater hydrographs and data on groundwater contribution to streams are relatively close. Values derived from low-flow data, however, were consistently smaller. This discrepancy is related to two factors: (1) the limited time for which records of low-flow measurement were available; (2) the severely limited accuracy of low-flow estimates. However, the use of all three methods in conjunction does provide meaningful estimates of groundwater resources.
