The G-WaLe System

The G-WaLe system consists of several self-contained mobile floaters with integrated GNSS receivers connected to a fixed housing containing power supply system, data storage system and data transmitter.

  1. After being deployed, G-WaLe floaters remain anchored at a fixed position. The z-com-ponent of the measurement provides information on the water level at the floater position.
  2. The position of the floater is either stored internally or transmitted (via GSM; radio or satellite links) to a central (mobile or stationary) unit.
  3. Water Management institutions process the data to establish ad-hoc or short term water level forecasts.
  4. In case of critical situations, alerts are established and distributed (e.g. with the help of MIKE FLOOD WATCH von DHI).
