项目摘要

In these days, water resources managements on a catchment basis are very necessitated because of the growing importance of regional and environmental planning. Analyses on human activity effects on hydrological cycles were thus focused in this study. Two fundamental researches on basic movement of water in catchments were firstly performed such as :1) Mechanism of returning flow from agricultural water use (by Goto) ; A new hydrological simulation with meshed tank model was successfully performed to analyze several actual river systems, resulting in the accurate estimation of the total return flows. Snow melt factors were also included in this model.2) Unsteady flow simulation in rivers (by Kubo) ; The developed new skemes much reduced CPU-time consumption, enabling a long term calculation of actual large river systems. The developed method could estimate lead time of the flow released from resource reservoir at the water users in Tone-river to be used in their daily operations.The third research was on : 3) The management logic of actual water system operators (by Nakamura) ; Field studies were conducted on Naka-river agricultural water system and the operators' experience was formulated with the use of knowledge engineering language, PROLOG. With this language, a program was formulated including both the logic and the physical water flow in water systems. An overall simulation of a total system was thus performed.Methods developed by the above three researches will be useful in making the actual decision of operations, especially in the case of severe drought conditions on actual large rivers.

在这些日子里，由于区域和环境规划的重要性日益增加，以流域为基础的水资源管理非常必要。因此，本研究着重分析人类活动对水文循环的影响。首先对流域水的基本运动进行了两方面的基础研究：（1）后藤的农业用水回流机理研究，成功地利用网格水槽模型对几个实际水系进行了水文模拟，准确地估算了总回流量。该模型还包括融雪因子。2）河流非恒定流模拟（Kubo）;开发的新skemes大大减少了CPU时间消耗，使实际大型河流系统的长期计算成为可能。开发的方法可以估计提前时间释放的流量从资源水库在水用户在音河，以用于他们的日常业务。第三个研究是：3）实际的水系统运营商的管理逻辑（由中村），进行了实地研究中河农业水系统和运营商的经验，制定了使用知识工程语言，PROTECH。用这种语言，制定了一个程序，包括在水系统中的逻辑和物理水流。以上三项研究所建立的方法对实际调度决策，特别是在实际大江大河严重干旱情况下的调度决策具有一定的参考价值。
