Hydrological Measurement – Spring Containment

Project: Hydrological Measurement – Spring Containment
Location: Rindberg - Sibratsgfäll, Vorarlberg, Austria

Conceptual formulation
Three springs were contained in the village of Sibratsgfäll in the Bregenz forest. Various spring data has to be logged continuously in order to monitor water quality and discharges.

Solution
The springs were jointly contained in a Thompson weir. The amount of water discharged can be determined by continuously measuring the water level by means of an immersed probe. Conductivity measurement provides evidence of the catchment area of the springs and water quality. The quantity of precipitation is measured by an automatic rain gauge in order to observe the possible influence of precipitation on water quality.

Implementation
Spring data is transmitted to a central data acquisition unit in the village over a radio link. Together with the precipitation information measured there, this data can be retrieved thanks to remote data transmission. Measured values can therefore be analysed precisely and conveniently from the office using METWin analysis software.
