Data Acquisition & Telemetry


Early flood warning system in place for Strand residents

April 2002 Data Acquisition & Telemetry

Cape Metropolitan Council is using high technology solutions to predict potential disaster situations in their water management programme for Strand and adjoining low-lying areas.

Consulting engineers Stewart Scott Consultants were responsible for implementing the control and prediction system. They selected a system from CS System Solutions, which included a new Adroit scada system to be installed at the disaster monitoring room at Strand fire station. The Adroit scada is connected to several outstations via a Motorola Moscad radio telemetry system. The Adroit scada in turn connects to the central station via an RS232 Modbus communications link.

Information from the rainfall and river level gauges at the outstations is transmitted back to the central unit and this information is displayed, collected and manipulated within the Adroit scada system. CS System Solutions used Adroit's open database connectivity tools to log the rainfall and river level information to a MS SQL database at regular intervals. This was done to provide long-term data collection in an open tool that allows integration and interrogation, using other packages and over a network.

The Adroit scada also uses the SQL database to interface with a flood prediction algorithm that was developed by Stewart Scott Consultants. The algorithm takes the current data together with a 2-hour history and predicts the expected river levels taking the terrain and water run off data into consideration.

The results of this algorithm are then available as a graphical trend display from within the Adroit scada. The algorithm also calculates a severity index of 0-10. This value is displayed and in the case of potential flooding, alarmed on the Adroit scada mimic screens. The alarm alerts the monitoring staff at the disaster monitoring room to the potential flood situation. They are then able, through a prepared method of notification, to timeously warn residents in low lying or affected areas downstream of the monitored river points.

With extensive experience in water monitoring systems, Adroit Systems' scada was considered the best choice for this vital installation in Cape Town.
