HYDRAULIC MODEL OF HARCOV HISTORICAL DAM
Original language description
The article deals with increase of safety of dams in connection with increasing safety standards, and it focuses on intelligent and careful methods of saving their cultural and historical value. The example is the historical dam Harcov: here, the hydraulic solution allowed to increase the safety of the dam in agreement with technical norm TNV 75 2935 "Considering safety of dams in case of flood", and regulation No. 590/2002 Sb., about technical standards for dams, and at the same time, the original historical nature of the dam could be preserved. To evaluate the suggested change on the spillway, hydraulic physical modelling was used. The technique has its justification if complicated construction settings of safety spillways are tackled safety facilities of dams and their capacity and safety. In case of Harcov Dam, a new shape of the overflow surface with a low-pressure regime of water flow was designed for floods higher than Q(20) (20-years-flood). For evaluating the original and the newly designed condition of the safety spillway and objects related to Harcov Dam, a physical model at a scale M - 1: 20 was used which accurately describes circulation on this object. The capacity of the newly designed spillway is at surface level of safety limit water level 373,80 m a. s. l. 76,3 m(3).s(-1); that in sum with a bottom outlets is adequate to flow rate Q(10 000). The project documentation for reconstructing the dam will be properly solved on the base of results of the physical model research.
