| 内容記述 | The coastal lowland region around closed-off section of Ariake Bay where creek canal networks for irrigation are distributed, is divided into fi ve distinct areas; the area of Shiroishi Plane, the Kase-river-supplied area, the right bank of the Chikugo-river-supplied area, the left bank of the Chikugo-river-supplied area and the Yabe-river-supplied area under conditions of water sources. Seasonal and annual fl uctuation patterns of creek water quality in each area are summarized as follows; 1) The area of Shiroishi Plain: The values of concentrations of SS, COD, T-N, T-P and Chl-a in creek canal water show the highest values in the coastal lowland region. This area is apt to be insuffi cient irrigation water because the water sources are mainly restricted within small irrigation ponds. The farmers manage to be used the irrigation water as carefully as they could. Creek water is recycle used for irrigation water in many times so that long residence time of water in creek canals causes a deterioration of water quality. Therefore, nutrient concentrations in creek water are higher than those of other areas. Increasing of T-N during winter may cause to apply much fertilizer to the onion fi elds. 2) The Kase-river-sourced creek area: The sewage system was partly installed in this area. Water quality was not improved by installation of the sewage system. The treated water at the sewage treatment plant fl ows into not creek canals but the outside-creek river. It is considered that the infl ow volume of municipal drainage water decreased, and decrease of infl ows made the water shortage responding to declining of water quality. 3) The right bank of the Chikugo-river-sourced area: The creek water quality was comparatively clean. Unique phenomenon was observed that T-N concentration in the downstream side of the creek canal was lower than that in the intake point from the river which was water source. 4) The left bank of the Chikugo-river-sourced area: Nutrient concentrations in the creek water were comparatively high because of the high population density and no sewage system. 5) The Yabe-river-sourced area: Water source has been stable by the installation of water supply system from the Chikugo River in a dry spell from 1966. Suffi cient amount of water makes the residence time of water in creek canal shorter, and leads the water quality conservation in the creek canals. Both the reduction of infl uent nutrient loads and the development of stable water source are considered to be important to achieve the water quality conservation. There is the possibility that decreasing in volume of water by sewage treatment cause the deteriorating of water quality. The measurements of both the reduction of infl uent nutrient loads and the development of stable water source are requested. |
