Measurements of suspended sediments in the catchment area of the Kamniška Bistrica river

Erozija ter posledično transport rečnih sedimentov, je pomemben in stalno prisoten proces v vseh vodotokih. S transportom materiala je povezano nenehno spreminjanje in preoblikovanje same rečne struge ter njene okolice. Zaradi tega je spremljanje in poznavanje omenjenih procesov ključno za razumevanje in trajnostno upravljanje vodotokov. V okviru diplomske naloge sem obravnaval rečni transport sedimentov, najbolj pa sem se posvetil rinjenim in lebdečim plavinam. Konkretne meritve in izračune sem izvajal na vodotokih Kamniška Bistrica in Pšata.Erosion and consequently the transport of river sediments is an important and constantly present process in all watercourses. The transport of material is associated with the constant change and transformation of the river bed itself and its surroundings. Therefore, monitoring and knowledge of these processes are crucial for understanding and sustainable management of watercourses. As part of my thesis, I dealt with river transport of sediments, focusing mainly on bed load and suspended load. I have been performing measurements and calculations for these two types of sediments on the Kamniška Bistrica and Pšata watercourses. The main goal of my thesis was, in the scope of the computational part, to determine the impact of precipitation and water flows on the content of suspended solids in the river flow. As a result, I wanted to derive the equation, to connect the river flows with the amounts of suspended solids. So in the future, only by using these two formulas, each of the considered watercourses needs its own, we could estimate the suspended solids for these considered watercourses. Only river flow values would be needed as input. I also correlated the amount of daily precipitation and suspended solids in the same way, but it turned out to be less appropriate. Estimated suspended solid based on the derived equations should be regarded as rough approximation of the actual state in the rivers while continus measurements are needed to enhance these estimates. Bed load transport at the selected locations in the Kamniška Bistrica river was also evaluated
