Construction & Rehabilitation of Surface Water Monitoring Stations

 

The Construction and Rehabilitation of monitoring stations is done to ensure availability of regular data on water flows. The project will involve two activities – the first one involves automating 10 sites through installing multi-parameter telemetric stations which allow for water level measurements and other water resources data collected at remote or inaccessible points and transmitted real time to receiving equipment for monitoring.

The second activity: Rehabilitation of 60 Regular gauging stations begins with fulfilling two prerequisites (which have been carried out so far ):

These include Technical assessment and extraction of information from the Daily History (DH) files.

The major areas to focus on during the technical assessment are;

The assessment of the control itself, i.e. the hydraulic condition of the station and its ability to provide a unique (unambiguous) relationship between the stage (water level) and the discharge and to which extent the control (and thereby the stage-discharge relationship) will remain stable is the most important part of the assessment.

  1. Extracting necessary information from the DH files.

The actual rehabilitation of 60 RGSs will involve any of the following activities (based on a need by case basis):

Replacement of gauge plates

Installation of struts and gauge plates

Establishment of a benchmark

In all cases a cross-section and establishment of a benchmark (where not found) will be done

So far WRA has 220 RGS stations in place.
