KarstMod is a collaborative project developed by the French SNO Karst.

It provides a platform for global modeling of the rain-level-flow relationship in karstic basins. The platform provides a set of tools to assess the dynamics of the compartments considered in the model, and detect possible flaws in structure and parameterization. This platform is developed as part of the KARST observatory network initiated by INSU / CNRS, which aims to strengthen the sharing of knowledge and promote interdisciplinary research on karst systems at national level.
