Hydrology

The Sierra Leone Meteorological Agency (SLMet), in partnership with the Ministry of Water Resources, operates a comprehensive network of automated hydrologic and meteorological monitoring stations throughout Sierra Leone to provide critical water and weather information for effective water resource management. Our hydro-meteorological monitoring system, known as Hydromet, uses advanced remote data collection platforms that transmit real-time water level, rainfall, and environmental data via radio and satellite communications to support flood forecasting, drought monitoring, water supply management, and reservoir operations. This integrated approach combines meteorological observations with hydrological data to deliver timely information that helps communities, government agencies, and water managers make informed decisions about water security, flood preparedness, and sustainable water resource utilization across the country.
