Abstract

This study presents the development of LuKARS 2.0 on an hourly scale. The model concept was modified in comparison to the original model from Bittner et al. (2018) by considering the interaction between matrix and conduit as well as possible surface water bypassing the spring. This allows a flexible conceptualization of binary karst systems characterized by a perennial spring and intermittent overflow. The aim of this study is to investigate the relevance of high-resolution hydrochemical data for the verification and selection of conceptual event-based karst models. The model was tested on the Baget karst system, France, whose recharge area shows the coexistence of karst and non-karst formations. The results of this study shows that despite different model parametrizations simulate the discharge at the spring with comparable accuracy, not all of them match the observed hydrochemical data.
