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

未测量流域预测（PUB）是流域水文学中一个经典的未解决问题，在全球气候变化背景下对区域水文预测具有越来越重要的意义。解决这一问题的基本方法需要深刻理解围绕水文通量尺度、网络几何及其相互关系的经验和理论问题，这是本文提出的主要研究重点。拟议研究的三个广泛而具体的目标是发展和测试空间变异性的标度理论，（一）在河流流域的水文通量中，（二）在三维渠道网络几何形状的基于链接的描述中，以及（三）为几个选定的流域建立和使用适当的数据库，以测试理论假设和预测。整个项目的一部分从1991年7月开始由NASA资助，为期三年。如附录四所示。NSF的预算是对NASA提供的资金的补充。

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.
