We want to find out if and how experimentally accessible hard and soft information can be combined into a physics-based quantitative representation of field-scale soil hydrology, given the situation that process models, material properties, forcings, and observations are all incomplete and inaccurate to some degree.We approach this along three synergistic lines: (i) hydraulic experiments at a fully controlled artificial and at a natural test site, (ii) high-precision GPR- and TDR-measurements, (iii) constructive inversion and data assimilation.

我们想知道，在过程模型、物质特性、强迫和观测都不完整和不准确的情况下，是否以及如何将实验上可获得的硬信息和软信息结合到基于物理学的野外尺度土壤水文学的定量表示中。我们沿着沿着三条协同路线进行：（一）在完全受控的人工和天然试验场进行水力试验，（二）高精度探地雷达和时域反射测量，（三）建设性反演和数据同化。
