Telemetry for Rainfall Stations
In early 2007, a field monitoring station with telemetric capabilities was established to collect rainfall and runoff data off a roof catchment located at the Water Research Laboratory. The data collection system enables hydrologic information such as rainfall depths and runoff volumes to be obtained during the occurrence of rainfall storm events.
Collected data was transmitted in real time via General Packet Radio Service (GPRS) to an internet server for storage. Based on the data transmission success rate, the system during the monitoring period was found to be highly reliable. Benefits of incorporating such a system into modern hydrologic data collection stations were evident, and operation of the field station can be monitored without having to be present at the site.
This new approach in collecting hydrologic data will be valuable for practical applications at remote locations and also minimising interruption during data collection exercises.
