Abstract

Estimation of ecological water demand of groundwater dependent ecosystems is essential in quantitative status assessment of groundwater bodies. In the Hungarian River Basin Management Plan a top-down approach was applied that — due to its resolution and data distribution — proved to be inaccurate in case of critical areas. A more sophisticated method was developed in cooperation with the Institute of Ecology and Botany of the Hungarian Academy of Sciences, which — as a bottom-up approach — is appropriate to calculate groundwater demand of habitats more precisely at regional or even local scale. Comparison of the methods is illustrated in the Nyírség-Lónyay and Rétköz groundwater body group.
