The Problem

Measured water levels are keystones for model calibration and flood forecasting.

Today, water level measurements systems rely on fixed gauging stations and even in large river systems exist only a few of them.

The System

The aim of G-WaLe is to develop and apply a mobile self-maintained water level measurement device using the Galileo commercial service.

The G-WaLe system consists of several self-contained mobile floaters with integrated GNSS receivers connected to a fixed housing.

Advantages

Simple and cost-effective floater units make it possible to install multiple measure-ment units.

High spatial and temporal resolution of water level profile.

High reliability due to redundant measurement units of the simple system.
