In this study, the main purpose are to davelop new approach for water management and control in open channel network in lowlands. water quality and self-purification function are investigated trough field survey in open channel systems in Saga area. Two approach for improving water quality are evaluated by using newly developed computer model. The first approach is a dilution method of inducing clean water from a main river. The second one is to improve the water quality by controlling biological reaction. For improving water quality directy in Saga creeks, it is clear that the dilution method is an appropriate application. Also, combined systems of the dilution and reduction method should be selected from the view point of integrated water quality management. A policy analysis is applied to Ushizu area as a case study from the view point of the integrated water management. The results of the case study show that it is possible to do a small scale policy analysis in Japan. Simple sets of measures can improve some of the water related problems considerably.

本研究的主要目的是为低地明渠网的水管理和控制提供新的途径。通过野外调查研究了萨嘎地区明渠系统的水质和自净功能。利用新建立的计算机模型对两种改善水质的方法进行了评价。第一种方法是稀释法，从主要河流中引入清洁水。二是通过控制生物反应来改善水质。为了直接改善佐贺溪的水质，稀释法显然是一种合适的应用方法。从水质综合管理的角度考虑，应选择稀释法和还原法相结合的系统。从水资源综合管理的角度出发，以九州地区为例进行了政策分析。案例研究的结果表明，在日本进行小规模的政策分析是可能的。一些简单的措施可以大大改善一些与水有关的问题。
