In typical midland catchments in moderate climate, groundwater flow in floodplains is mainly down-valley oriented. However, the hydrological functioning of floodplains is also linked to the presence or absence of major hydrogeological features, and depends on the connection of the local groundwater systems to different floodplain margins. The goal of this project is to elucidate the hydrogeological drivers that determine water and solute fluxes across and control the redox reactivity at floodplain margins. We determine the relative importance of the margins to the overall fluxes and solute turnover in the floodplain by geophysical and hydrogeological techniques. The results are a prerequisite for the interpretation of physical and biogeochemical data and feed into the stochastic groundwater models.

在气候温和的典型米德兰流域，洪泛区的地下水流主要是沿山谷向下的。然而，洪泛区的水文功能也与主要水文地质特征的存在与否有关，并取决于当地地下水系统与不同洪泛区边缘的连接。该项目的目标是阐明水文地质驱动因素，确定水和溶质通量和控制在洪泛区边缘的氧化还原反应。我们确定的相对重要性的利润率的整体通量和溶质周转在河漫滩的地球物理和水文地质技术。这些结果是解释物理和地球化学数据的先决条件，并输入随机地下水模型。
