- | The correlations between different drought indicators (e.g. SPI, SPEI) and the number of drought impact occurrences in Germany and England suggested that droughts propagate on different timescales through the hydrological system. The aggregation period of such drought indicators in combination with the occurrence of impacts might be a good first estimator of available water storage (and storage characteristics such as depletion rate and maximum storage) in regions with different geology. | + | The correlations between different drought indicators (e.g. SPI, SPEI) and the number of drought impact occurrences in Germany and England suggested that droughts propagate on different timescales through the hydrological system |

Kirchner (2009) presented a elegant method to derive a dynamic catchment storage solely from streamflow data. If the drought propagation and impact occurrence timescales in southern Germany are different from those in southeast England, then also differences in catchment storage between the two regions should be explorable. If so, different drought impact categories, but also the geology can be used as an explanation for different drought propagation timescales (e.g. Stoelzle, 2014). | Kirchner (2009) presented a elegant method to derive a dynamic catchment storage solely from streamflow data.
