<p>Prof. Intze, University of Aachen, was about 100 years ago the initiator and designer of nearly 30 masonry gravity dams in Germany, which are still in operation. According to the German dam standards all dams have to be monitored and rehabilitated to find any safety deficits.</p><p>Nearly all dams were rehabilitated due to ageing and uplift problems. The methods used are described. Now these dams should be able to serve another 100 years for water supply, energy production, flood control and recreation.</p>
