| 2 | 基于学习的沿海管理显示文摘许多国际捐助机构,包括Sida,都在促进边学习,边完善的沿海管理方式。它的假设是沿海管理起源在于公共政策的实验,并应该以此种方式进行限定和评价。本文通过对重新构建美国70年代和80年代初期沿海管理基础概念对这一途径进行了讨论。这些假设在由美国国际开发署(USAID)资助的始于1985年的3个试验项目中得到了应用。这导致了以参与性和事件驱动为特征的在沿海管理中的国家行动以及国家和区域研究机构的建立。所有这3个试验项目都成功地实现了在由培训和计划行动向当今国家管理机构正式组成部分的转换,并且,它们在实施期间内也得到了足够的资助。本文同时介绍了在实施基于学习的沿海管理方法中所学到的教训。 | Stephen B.Olsen James Tobey Lynne Z.Hale 徐尚平 | 1998 | 人类环境杂志1998，27，8： | 1 |
| 3 | Numerical analysis of synthetic granulate deposition in a physical model study显示文摘The current study focuses on the application of a three-dimensional numerical model for the prediction of morphological bed changes.The sediment deposition in a reservoir during a 10-year-fiood was investigated and the results of the simulation were validated with data derived from a physical model study.Because of the small grain sizes in the prototype,synthetic granulate was used in the physical model.The numerical computation domain was a reproduction of the physical model,including the grain sizes and the density of the particles,in order to ensure comparability.The CFD code SSIIM,which solves the RANS-equations in three-dimensions,was used for the simulations.The sediment transport in SSIIM is divided into suspended sediment transport,computed by solving the convection-diffusion equation,and bed-load transport,calculated by an empirical formula.The results of the numerical simulation correspond well to the results of the physical model study.The simulated location and the pattern of the sediment deposition in the reservoir are an accurate representation of the observed distribution in the physical model. | Gabriele HARB Stefan HAUN Joséf SCHNEIDER Nils Reidar B.OLSEN | 2014 | International Journal of Sediment Research2014，29，1： | 0 |
