Measurement

Runoff measurement methods and techniques

Water levels and discharge are recorded through regular measurements made at permanent measuring stations and spot measurements at temporary points by the Swiss National Hydrological Survey (LH), a number of cantons, research institutes and private bodies. At times of flood peak discharge is recorded and during dry periods minimum discharge. A range of measuring instruments and methods are used depending on the different types of rivers and lakes and the enormous range of variation in results (from The Hydrology of Switzerland, 1999).

In this publication of the Federal Office for Water and Geology methods are described for the measuring water level and runoff from page 47 onward.
