Quantitative Vadose Zone Hydrology using Ground-Penetrating Radar and Data Assimilation

考虑到过程模型、材料特性、强迫和观测在某种程度上都是不完整和不准确的，我们想要找出是否以及如何将实验上可获得的硬信息和软信息组合成基于物理的野外尺度土壤水文定量表示。我们沿着三条协同路线来解决这个问题：(i)在完全受控的人工和自然试验场进行水力实验，（ii）高精度GPR和tdr测量，（iii）建设性反演和数据同化。

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.
