Abstract: This paper presents the results of a series of experiments on “Dam Break” for the purpose of providing data to serve as a comparison for a numerical model. A typical process of “Dam Break”, in which water flows under extreme conditions, was simulated in a tank divided into two parts and equipped with a watergate at the hydraulics facilities of the CITEEC (Research Center in Civil Engineering) in La Coruna (Spain). As the watergate opens, the water flows from the full part of the tank into the empty area. The experimental design allowed us to measure depths and water velocity throughout the whole process, from the opening of the gate until the water reached a state of relative calm to obtain data on the temporal evolution of the flood to be compared with those acquired numerically. The “Dam-Break” process was simulated by setting several depths of water in the downstream tank allowing the free flood of water in the first series, while in the second series an obstacle was added to the experimental design in the downstream tank. The entire process of controlling the instrumentation and data acquisition was monitored by software.
