ABSTRACT Groundwater level fluctuations are caused by spatial and temporal superposition of processes within and outside the aquifer system. Most of the subsurface processes are usually observed on a small scale. Upscaling to the regional scale, as required for future climate change scenarios, is difficult due to data scarcity and increasing complexity. In contrast to the limited availability of system characteristics, high-resolution data records of groundwater hydrographs are more generally available. Exploiting the information contained in these records should thus be a priority for analysis of the chronical lack of data describing groundwater system characteristics. This study analyses the applicability of 63 indices derived from daily hydrographs to quantify different dynamics of groundwater levels in unconfined gravel aquifers from three groundwater regions (Bavaria, Germany). Based on the results of two different skill tests, the study aids index selection for different dynamic components of groundwater hydrographs.

比较水文地质学——对邻近观测井地下水动态的参考分析

摘要 地下水位波动是由含水层系统内外过程的空间和时间叠加引起的。大多数地下过程通常是在小范围内观察到的。由于数据稀缺和日益复杂，难以按照未来气候变化情景的要求升级到区域尺度。与系统特征的有限可用性相比，地下水水位线的高分辨率数据记录更普遍可用。因此，利用这些记录中包含的信息应该是分析描述地下水系统特征的数据长期缺乏的优先事项。本研究分析了源自每日水文过程线的 63 个指数的适用性，以量化来自三个地下水区域（德国巴伐利亚）的无承压砾石含水层中地下水位的不同动态。基于两种不同技能测试的结果，该研究有助于地下水水位线不同动态分量的指标选择。
