Background
Hydrological monitoring infrastructure provides the technical base for managing rivers, rainfall, and water-related risks. Automatic hydrological stations measure river water levels and rainfall through installed sensors and transmit data for water-resource monitoring. Reliable hydrological data supports flood warning, reservoir operation, irrigation planning, and river-basin management in Cambodia.
The Ministry of Water Resources and Meteorology is the national institution responsible for water resources and meteorological services in Cambodia. Within the ministry, technical hydrology and river units maintain monitoring stations so that field instruments can continue collecting usable measurements. Station maintenance is a core operational function because blocked rain gauges, weak batteries, damaged components, or vegetation around sensors can reduce data accuracy.
In provinces such as Pursat and Battambang, water monitoring is relevant to upland catchments, agricultural areas, and river systems that require continuous observation. A functioning station network allows officials to compare field conditions across locations and maintain a data record for water management decisions.
Key Developments
On 5 May 2026, technical officials from the Department of Hydrology and River Works under the Ministry of Water Resources and Meteorology continued a field mission to inspect, repair, and maintain automatic hydrological stations in Pursat and Battambang provinces.
The mission covered five stations: Veal Veng station in Pramaoy village, Pramaoy commune, Veal Veng district, Pursat province; Tuol Kruos station in Charuk village, Pramaoy commune, Veal Veng district, Pursat province; Kanghot station in Tuol Andet village, Kantueu 2 commune, Banan district, Battambang province; Kranuong station in Ta Sanh village, Ta Sanh commune, Samlout district, Battambang province; and Samlout station in Svay Chrum village, Kampong Lpov commune, Samlout district, Battambang province.
Operational Implications
The technical work included replacing batteries and drying devices, checking and verifying data from water-level measurement equipment, and cleaning rainfall measurement devices to prevent drainage openings from being blocked by dust or leaves.
The team also cut tree branches and cleared grass around station areas. These tasks were intended to help the equipment operate properly and transmit data accurately and efficiently.
Institutional Role
The field mission demonstrates MOWRAM’s operational role in maintaining Cambodia’s hydrological monitoring network. Regular inspection and repair of field stations help preserve the continuity of water-level and rainfall records used by public authorities for water-resource management.
