Recently, it has been understood that improvement of tertiaries and on-farm water management are most important for large scale paddy irrigation projects. The Miyata Yosui Land Improvement District (the Miyata LID) in Aichi Prefecture, located in central Japan is used as a case study in this paper. During the 1970s, rapid urbanization in and around the command area caused a ntimbei, of problems in the operation and maintenance of the irrigation system, including difficulty in recruiting OM workers, water contamination by trash and effltient fron)the expanding city area, decreasing income and increasing costs in running the LID.The Miyata LID and some other LIDs decided to rehabilitate their main facilities (including replacement of open ditches with pipelines) and install telemetric control and monitoring units with a centralizing control system. This system is not an optimizing water distribution system which automatically determined by computer when to irrigate and how much water sho … More uld be, applied linking soil water depression and meteorological data. Only major structures are controlled and monitored from the remote central site.The niodern system has made it easy to operate and maintain the canal system, and is labor conserving. The Miyata LID has been satisfied with its use of the pipeline system to prevent water contamination, however, some unexpected problems have arisen. Small gates/valves and many direct inlets which were not equipped with TC/TM units caused imbalances of water distribution in the system. The pipeline system brought about the loss of the reuse system of agricultural return flow. The available water source of return flow has been lost. These problems neccesitate additional OM workers. Also, as irrigation scheduling has not been altered, LID operators and farmers have still not reaped full benefit from the system. For the success of modernization, more attention should be directed towards institutional matters (soft ware) related to the new system (hard ware). Less

近年来，人们已经认识到，改善第三系和农田水管理是大规模水稻灌溉工程的最重要的。本文以日本中部爱知县的宫田洋井土地改良区为例进行研究。在20世纪70年代，指挥区及其周边地区的快速城市化造成了灌溉系统运行和维护方面的一系列问题，包括难以招募OM工人，垃圾和污水污染了水，宫田LID和其他一些LID决定修复他们的主要设施，（包括用管道取代明沟）和安装具有集中控制系统的遥测控制和监测装置。该系统不是由计算机自动确定何时灌溉、应灌水量的优化配水系统， ...更多信息 结合土壤水分亏缺和气象资料进行应用。只有主要的建筑物才能从远程中心站点进行控制和监控。niodern系统使运河系统的操作和维护变得容易，并且节省了劳动力。Miyata LID对使用管道系统防止水污染感到满意，但是出现了一些意想不到的问题。没有配备TC/TM装置的小闸门/阀门和许多直接入口导致系统中的水分配不平衡。管道系统带来了农业回流再利用系统的损失。已失去可利用的回流水源。这些问题需要额外的OM工人。此外，由于灌溉计划没有改变，LID运营商和农民仍然没有从该系统中获得充分利益。为使现代化取得成功，应更多地注意与新系统（硬件）有关的体制问题（软件）。少
