The cantonal discharge measurement station on the river Giessen in the canton of Thurgau required replacing. A measurement station was constructed at a new location to provide representative data from the entire drainage area with improved accuracy of measurement. As the river Giessen is a lateral tributary of the river Thur, a fish ladder also had to be provided.
Option study, construction project, invitation to tender up to and including implementation. In particular, calibration of the new measurement station by means of discharge measurements and numerical calculations.
