	[[File:04_G_Messungen_03.jpg\|200px\|thumb\|right\|Picture 4: Measuring pendulum in Edertal dam]]Geodynamic measurements are used to ascertain the emission, propagation and impact of vibrations caused by construction work and operation at and on waterways. Vibrations in waterways are generated for example when installing sheet piling, during loosening and demolition blasting, during chiselling work, during surface and in-depth compaction of the ground, from propulsion systems of vessels, from vessel impact when mooring and from stationary systems such as pumps and machines, together with the flow forces, e.g. at locks.

[[File:04_G_Messungen_01.jpg|200px|thumb|right|Picture 2: Measuring system installed in the bottom of a drained lock chamber]]Standard measurements include the loading tests on piles and anchors as stipulated in the standards. Measurements are also carried out at slopes, retaining structures and foundations for the preservation of evidence and when using the observational method. Measurements at structures, foundation elements, in the ground and on models can be useful for design in cases where neither theoretical principles nor practical experience is available to provide reliable, economic solutions for geotechnical problems in waterways engineering.
