Collaborative Research: Scaling Theories of Hydrology, Hydraulics and Geometry of River Networks

无资料流域预报是流域水文学中一个经典的悬而未决的问题，在全球气候变化的背景下，流域水文预报对区域水文预报具有越来越重要的意义。解决这一问题的基本方法需要对水文通量尺度、网络几何及其相互关系的经验和理论问题有深入的了解，这构成了这里提出的研究的主要焦点。拟议研究的三个广泛但具体的目标是发展和测试空间变异性的尺度理论，包括：(1)河流流域的水文学通量；(2)基于链接的三维河网几何描述；(3)为选定的几个流域建立和使用适当的数据库，以检验理论假设和预测。从1991年7月开始，这一总项目的一部分由美国宇航局提供三年的部分资金。这一点如附录四所示。NSF的预算补充了NASA提供的资金。

Prediction from ungauged basins (PUB) is a classic unsolved problem in river basin hydrology which has increasingly important implications for making regional hydrologic predictions due to global climate change. The basic approach towards a solution of this problem requires a deep understanding of empirical and theoretical issues surrounding scaling in hydrologic fluxes, the network geometry and their interretionships, and constitutes the main focus of the research proposed here. The three broad but specific objectives of the proposed research are to develop and test scaling theories of spatial variability, (i) in hydrologic fluxes in river basins, (ii) in link based descriptions of three- dimensional channel network geometry, and (iii) to establish and employ appropriate data bases for a few select basins for testing theoretical hypotheses and predictions. A portion of this total project was funded in part for three years by NASA beginning July 1991. This is shown in Appendix IV. The budget for NSF complements the fund provided by NASA.
