FIELD WATER MANAGEMENT SYSTEM

To provide a field water management system that can perform optimal water supply to the ground surface and underground based on the result of measurement through a measurement device.SOLUTION: A field water management system comprises a water management device that can manage water supply to a ground surface H1 of a field H and water supply to underground H2 of the field H; a water-level water-temperature sensor 20 movable to a first position P1 where the water level and water temperature of the ground surface H1 can be measured and a second position P2 where the water level and water temperature of the underground H2 can be measured; and a field management server that can control the water management device based on the result of measurement through the water-level water-temperature sensor 20. The field management server can execute, as a control mode for controlling the water management device, a surface irrigation mode for managing water supply to the ground surface H1 and an underground irrigation mode for managing water supply to the underground H2. Based on the result of water temperature measurement through the water-level water-temperature sensor 20, the control mode to be executed is determined.SELECTED DRAWING: Figure 3 【課題】測定装置の測定結果に基づいて地表面及び地下への給水を適切に行うことが可能な圃場水管理システムを提供する。【解決手段】圃場Ｈの地表面Ｈ１への給水、及び圃場Ｈの地下Ｈ２への給水を管理可能な水管理装置と、地表面Ｈ１の水位及び水温を測定可能な第一位置Ｐ１、並びに地下Ｈ２の水位及び水温を測定可能な第二位置Ｐ２に移動できるように構成される水位水温センサ２０と、水位水温センサ２０の測定結果に基づいて水管理装置を制御可能な圃場管理サーバと、を具備し、圃場管理サーバは、水管理装置を制御するための制御モードとして、地表面Ｈ１への給水を管理する表面灌漑モードと、地下Ｈ２への給水を管理する地下灌漑モードと、を実行可能に構成され、水位水温センサ２０による水温の測定結果に基づいて、実行する制御モードを判断する。【選択図】図３
