Povzetek
Ob večjih reguliranih vodotokih so se v preteklosti po opustelih rečnih rokavih vzpostavljale mlinščice predvsem za pogon vodosilnih objektov. S časoma, ko se je mlinarstvo začelo opuščati, se je s tem prekinilo tudi vzdrževanje odvzemnih objektov in dolvodnih kanalov. Danes se je pojavila težnja po ponovni oživitvi in ovodenitvi mlinščic. Pogosto je problem sprememba morfologije ali poglabljanje glavnih strug, ki danes mlinščicam ne omogočajo več zadostnega dotoka vode. Zato je treba vtočni objekt oblikovati na način, da bo izpolnjen pogoj vodnega gospodarstva o neprekinjenem in zadostnem dotoku v oživljeno mlinščico. V nalogi je reševanje problema predstavljeno na primeru 11-mlinskega potoka ob Muri. Za ugotovitev najbolj optimalne oblike vtočnega objekta je bil s pomočjo programske opreme HEC-RAS vzpostavljen 2D hidravlični model. Dostopni vhodni podatki so se predhodno obdelali in pripravili v programski opremi ArcGIS. Analizirane so bile štiri različne ureditve zajetja in vtočnega objekta ter razmere primerjane s sedanjim stanjem. Za posamezno ureditev je bil preverjen vpliv na zagotovitev stalnega in neprekinjenega dotoka v času nizkega vodostaja Mure ter možnost vpliva na omejevanje odvzema in s tem na poplavne razmere v času visokih voda. Za preprečitev poplavljanja vzdolž 11-mlinskega potoka je na vtočnem objektu potrebna regulacija zapornice. Zaradi predvidene uporabe hidromehanske opreme je bil analiziran scenarij za primer ustreznega delovanja zapornic in za primer strojeloma. V ta namen je bil izdelan pravilnik o manevriranju z zapornico in predlagana vzpostavitev dodatnega visokovodnega zaporničnega objekta.

Modelling the multi-purpose intake of side channel on the example of the Enajstmlinski stream |
Sekundarni povzetek: |
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. |
