Hydrological Services Department


The Hydrological Services Department is responsible for the collection, processing and analyses of hydrological, hydrogeological, water quality data and other environmental information associated with the management of both surface and groundwater resources. The Department is also responsible for the operation and maintenance of hydrometric network and database, forecasting stream flows and river, lake stages, watershed modelling and hydraulic analysis of rivers, lakes and reservoirs. Furthermore, GIS and remote sensing are vital tools that the department uses to analyse geo-spatial and hydrometric dataset, delineate water catchments and monitor land use and land cover changes.  The department uses these monitoring data to model water quality and river flows to understand trends, patterns, and water balance in a river basin scale. The information obtained from the department is to ensure there is water security at sufficient quantity and desired quality for all in a sustainable environment.

Key Tasks

  • Water quality monitoring of all surface and groundwater resources through established water quality monitoring stations (reporting of SDG 6.3.2 indicator)
  • Development of hydrogeological and hydrological investigations to ensure that accurate and appropriate information are available for use in water resource management decisions.
  • Development of strategies for watershed protection and restoration to meet water supply and conservation goals and to ensure regulatory compliance with water laws or regulations.
  • Development of climate-related information for flood forecasting and early warning system and liaise with other relevant government institutions and environmental groups in the mitigation and adaptation of climate change.
  • Development of processes, guidelines, procedures, protocols, standards, and structures (including necessary management systems and technology tools) to establish databases, maps and records for all water bodies, ensuring their accuracy, security, integrity, and reliability.
  • Development of systems and processes for determining and mitigating point source pollution.
  • GIS and remote sensing tools for catchment mapping, delineation of river basins and the monitoring of land use and land cover changes
  • Collaborate with transboundary bodies and facilitate the process of data exchange from monitoring.
