Hydrometric Networks

HLS are one of the few non-governmental organisations in the UK with the track record and capability to design, operate and maintain hydrometric networks. Our expertise is derived from the background and experience of HLS Directors and senior staff. This includes extensive project experience not just in the UK but also advising overseas governments in the Eire, India, Hong Kong and Malawi, as well as the Southern Africa Development Community (SADC). 

A key strength of HLS is that, as well as collecting hydrometric data, we also use it. Our hydrologists undertake a wide range of analyses, as described elsewhere on this site, enabling our clients to make informed and robust decisions. The close link between the hydrometric services team and our hydrologists provides direct benefits in the quality of our data and how it is interpreted.  

Our capabilities and experience extend to the following:

  • Review and audit of existing networks
  • Rehabilitation of measurement infrastructure and instruments
  • Calibration of flow gauge ratings
  • Specification and introduction of new technology, where appropriate
  • Design and development of surface water archiving, rainfall and flow data processing systems
  • Installation and commissioning of telemetry systems for rainfall, level and flow
  • Operation and maintenance of surface and groundwater hydrometric networks
  • Design of local flood warning, water quality and pollution warning systems
  • Routine monthly and annual quality control and data reporting
  • Training programmes and best-practice manuals for national hydrometric networks.
