To provide an agricultural field water management system capable of simply and accurately adjusting the installation height of a water level gauge and the installation height of a drainage device.SOLUTION: The agricultural field water management system comprises: a field water management device equipped with a remote control unit that remotely controls a water supply device and a drainage device so that a water level in each field equipped with plumbing equipment, which includes the water supply device, the drainage device, and a water level gauge, reaches a set level; and a terminal device equipped with a control information processing unit that exchanges control information including water supply and drainage for the field with the field water management device. The control information processing unit is configured to transmit drainage water level calibration information for matching the amount of deviation between the origin of the water level gauge provided in the field and the origin of a drainage weir to the field water management device. The field water management device comprises: a calibration processing unit that updates the drainage water level calibration information and stores it in a storage unit; and a lifting-height setting unit that sets the lifting height of the drainage weir based on the drainage water level calibration information and the set water level.SELECTED DRAWING: Figure 2 【課題】水位計の設置高さと排水装置の設置高さを簡単かつ正確に調節することができる圃場水管理システムを提供する。【解決手段】給水装置、排水装置及び水位計を含む給排水機器が設置された各圃場の水位が設定水位になるように給水装置及び排水装置を遠隔制御する遠隔制御部を備えた圃場水管理装置と、圃場水管理装置との間で圃場に対する給排水を含む制御情報を遣り取りする制御情報処理部を備えた端末装置と、を備え、制御情報処理部は、圃場に備えた前記水位計の原点と排水堰の原点とのズレ量を整合させる排水水位校正情報を圃場水管理装置に送信するように構成し、圃場水管理装置は、排水水位校正情報を更新して記憶部に記憶する校正処理部と、排水水位校正情報と設定水位に基づいて排水堰の昇降高さを設定する昇降高さ設定部を備えている圃場水管理システム。【選択図】図２
