20.500.12556/RUL-131133 Spremenljivost rečnih profilov vodomernih postaj porečja Savinje diplomska naloga Variability of the river profiles of the gauging stations in the Savinja River catchment graduation thesis V Sloveniji imamo vzpostavljeno hidrološko mrežo vodomernih postaj, s pomočjo katere spremljamo razmere v vodotokih skoraj v realnem času. Sočasno pa se na vodomernih postajah izvajajo tudi občasne meritve pretokov za potrebe izdelave in posodabljanje pretočnih krivulj. Ker se v zadnjih letih za ta namen uporabljajo sodobni akustični merilniki, nam le-ti omogočajo tudi hkratno merjenje geometrije prečnega prereza. V nalogi smo predstavili obdelavo podatkov meritev prečnih profilov in prikazali njihovo spreminjanje za sedem vodomernih postaj na reki Savinji. Primerjali smo spremenljivost površin prečnih profilov glede na geodetski posnetek prečnega profila obravnavane vodomerne postaje in nadmorske višine nivelete dna v izbranih točkah znotraj prečnega profila vodomerne postaje. Rezultati analiz prikazujejo nenehno spreminjanje prečnih profilov zaradi odlaganja in odnašanja sedimentov. Ugotovili smo, da je večina največjih sprememb posledica odlaganja materiala. Vseeno pa dobljeni rezultati kažejo, da se struga Savinje v obravnavanih prečnih profilih dolgoročno gledano vseeno poglablja. Slovenia has a contemporary hydrological network of water gauging stations that monitor the situation of the watercourse in near real-time. At the same time, the occasional measurements of discharge are conducted at these stations in order to create and update rating curves. Modern acoustic gauges which have been used in recent years also enable the simultaneous measurement of the geometry of the cross-section. The present work presents the data analysis of the measurements of cross-sections and the representation of the changes in seven water gauging stations on Savinja river. We compared the variability of the surface of cross-sections with respect to the geodetic image of the river profile of a chosen gauging station was compared and the elevation of the river bottom level at points within the cross-section of the water gauging station. The results of the analysis show constant changes of the cross-section due to the erosion and accumulation of sediments. We found that most of the largest changes are due to material deposition. However, the obtained results show that the Savinja riverbed is still deepening in a long-term perspective. rečni profili vodomerne postaje Savinja river profile water gauging stations Savinja true true false [T.
