南水北调西线工程可调水量分析

在受水区缺水形势严峻的情况下，引水工程可调水量的确定主要与三个因素有关：一是引水河流及引水坝址径流量；二是坝址上下游用水要求；三是引水水库工程规模。在考虑各种因素影响后，提出各引水坝址可调水量占坝比径流量的比例在70％左右比较合适，按现阶段推荐的两种方案，可调水量可达160亿－170亿m^3.

本文将人工神经网络应用于二滩水电站以上支流鱼河的降雨径流预报，通过建模、计算、比较和分析可知，其非线性映射能力、自学习能力和灵活性，均能较好地反映降雨径流之间的非线性的、复杂的转换关系，结合流域水文特性并合理处理建模数据，值得进一步深入研究。     

川中丘陵区一种新型小流域径流输沙模型的建立与应用

径流输沙模型对定量评价水沙的输出响应具有重要的意义。本研究在已有研究成果的基础上，通过对四川盐亭县林山西沟小流域的径流、泥沙进行现场观测与分析，提出含沙量单位线的定义及其确定方法，建立了适应该小流域的径流输沙模型。并应用实测资料进行比较，表明模型的模拟结果可靠，模拟过程确定性系数达0．8以上，为川中丘陵区小流域径流输沙过程的预测预报提供了一个新方法。

1960年以来渭河下游河道的自动调整作用

1960年以来，渭河下游河道来水来沙条件和边界条件都发生了较大的变化，河道纵横剖面形态针对这些变化进行了相应的调整，通过分析河相关系、主槽面积、河底高程以及弯曲系数的调整规律，对渭河下游河道的自动调整作用进行了研究。     

贵州省枯季径流特性初步分析

在无资料地区以降水径流法推求径流资料系列时,除了要有年径流统计参数外,还应有其枯季径流和最枯月径流的有关指标,而由于受气候、下垫面条件(地形、植被、岩溶等)差异的影响,各地枯季径流特性各异。本文通过贵州省86个县、市、区气象站及45个水文站(控制集水面积由几十~上万km2)建站至今的实测资料分析,得出了贵州省各个地区枯季的时段、各站枯季径流统计参数、最小月径流模数和多年平均最小日均流量模数的关系,对了解贵州省的枯季径流特性和在无资料地区径流设计中都具有参考价值。     

Simulation Modeling of Runoff,Groundwater Flow and Sediment Transport into Kastoria Lake,Greece

Kastoria Lake is located in northwestern Greece. The whole basin of the lake is about 253 km². For the computation of the surface water volume inflowing into the lake from the main streams of the sub-basins located around Kastoria Lake, a rainfall-runoff sub-model is used. A quasi-three-dimensional simulation model of the Kastoria basin aquifer is also realized, in order to estimate the groundwater contribution to the volumetric budget of the lake and the whole basin as well. For the computation of sediment load inflowing into the lake from the main streams of the sub-basins, the rainfall-runoff sub-model is combinedwith a soil erosion sub-model and a sediment transport sub-model for streams. A GIS was developed in the hydrologic basin with all data needed for parameter identification and model application. The data base was enriched by a series of on site measurements of water discharge made in all main streams for one whole hydrologic year. By means of the resulting mathematical sediment model, those sub-basins, which deliver most sediment load to the lake, are identified. On the basis of this identification, a series of control measures, for the reduction of sediment inflowing into the lake, at certain places of the above mentioned sub-basins is proposed.
