Effectiveness to reduce runoff in a river basin containing irrigation tank systems laid on a plain was evaluated. The Shimizu River (CA=2.8km^2, L=2.5km) as a model on this research contains 14 irrigation tanks and their related channels. Surface area of all of the irrigation tank systems including related channels accounts for 23.7 percent of the catchments area.For the evaluation of effectiveness of irrigation tank systems, scenarios were considered as follows ;- both present irrigation tank systems and present water management for irrigation will be sustained in the future (Case A),- both all of the irrigation tank systems and their storage function will be abandoned (Case B),- present irrigation tank systems will be sustained, besides operation and management of the systems will be modified to reduce runoff in a river basin further (Case C).Based on precipitation data at Typhoon 15 in August and Typhoon 23 in October, 2005, runoff model of The Shimizu River was run by Kinematic Wave Method. For the Case B, temporary storage of rainfall upon the basin is not taken into account, because of loss of capacity on the irrigation tank systems.Although calculated peak discharge was 9.1m^3/s at Typhoon 15 and 10.1m^3/s at Typhoon 23 respectively on the Case B, calculated peak discharge was 4.2m^3/s at Typhoon 15 and 5.4m^3/s at Typhoon 23 respectively on the Case A. These results show that an effect on the Case A caused an about 46 through 53 percent decrease in peak discharge under a condition of precipitation on this research.For strengthening effectiveness to reduce runoff discharge such as the Case C, it was pointed out that selection of a suitable irrigation tank system taking into consideration arrangement and storage capacity would be important.

评估了减少含灌溉储罐系统的河流流域中径流的有效性。 Shimizu河（CA = 2.8 km^2，L = 2.5km）作为这项研究的模型，其中包含14个灌溉池及其相关通道。 Surface area of​​ all of the irrigation tank systems including related channels accounts for 23.7 percent of the catchments area.For the evaluation of effectiveness of irrigation tank systems, scenarios were considered as follows ;- both present irrigation tank systems and present water management for irrigation will be sustained in the future (Case A),- both all of the irrigation tank systems and their storage function will be abandoned (Case B),- present irrigation tank systems will be sustained, besides operation and management of the systems will be修改以减少河流盆地的径流（案例C）。基于8月15日在台风15和2005年10月台风23的降水数据上进行了修改，Shimizu河的径流模型由运动波波法运行。对于情况B，由于灌溉储罐系统上的容量损失，未考虑在盆地上暂时存放降雨量。尽管计算出的峰值排放量为9.1m^3/s在台风15和101m^3/s在typhoon 23上分别在案例B上的Typhoon 23分别在案例B上计算出4.2m^3/s的均为5.2m^3/S AT的结果。对案例A的影响在这项研究的降水状态下导致峰值排放的峰值排放量减少了约46％至53％。为了增强降低径流排放的有效性，例如CASE C，请指出，考虑到合适的灌溉水箱系统，考虑到考虑安排和存储能力，将很重要。
