In the past along the larger regulated watercourses small streams were established by abandoned river sleeves, primarily for the purpose for propulsion of mills. With the time when the mill began to abandon, the maintenance of the watercourses was also interrupted. Today there has been a tendency to regenerate those streams. The problem is the change in the morphology of the main watercourse, which today do not provide the side streams a sufficient supply of water. For this purpose, the intake facility must be designed in such a way that the condition of the water economy will be met for continuous and sufficient inflow.
In the thesis, solving the problem is presented on the example of an 11-mlinski stream along the Mura River. To determine the most optimal shape of the intake facility, a 2D hydraulic model was established using the HEC-RAS software. Accessible input data was pre-processed and prepared in ArcGIS software. Four different examples of the intake facility were analyzed and compared with the situation at the present time. For each arrangement, the impact on the provision of a continuous inflow during the low water level of the Mura River and the impact on the flood safety during high waters were verified. Due to the planned use of hydromechanical equipment a scenario was analyzed for the case of operational gates and for the case of machinery defect. In order to prevent flooding along the 11-mlinski stream, the gates at the intake facility needs to be managed. For this purpose, rules on maneuvering the gate was made and the establishment of a flood facility was proposed.
