摘要: 大尺度流域的水文地质参数的分布特征是一个困难的研究课题.提出一个新的直接反演法用于推算大流域的含水层参数值的分布.此模型的有效性在日本关东流域的应用得到了验证.Abstract: As groundwater researchers know, it is difficult to obtain basin-wide, distributed hydrngeological data and aquifer parameter data, especially in a large-scale watershed. In this research, the direct inverse method is employed to resolve the problem of identifying distributed aquifer parameters in a basin. The direct inverse method is faced with the So-called ill-posedness problem that makes the equations yield no solution. In order to overcome this difficulty, the non-optimization solution scheme is adopted. This model is validated by an application in the Kanto Plain, Japan.
