ANALYSIS OF FLOW MEASUREMENT WITH ACUSTIC DOPPLER CURRENT PROFILER

V diplomski nalogi se osredotočamo na teorijo in prakso merjenja pretokov rek z uporabo akustičnega Dopplerjevega merilnika pretokov (ADMP). Metoda pridobivanja podatkov je enako pomembna kot podatki, ki jih potrebujejo institucije oziroma ljudje, ki se ukvarjajo z dejavnostmi in problemi, povezanimi z vodo. Na začetku na kratko predstavljamo konvencionalne metode merjenja pretoka. V nadaljevanju obravnavamo teorijo delovanja ADMP in programske opreme WinRiver II. Sledi obravnava meritve pretoka z ADMP na terenu in prikaz predstavitve podatkov v programski opremi. Metoda merjenja z ADMP ima prednosti in slabosti. ADMP je zmožen meriti rečni pretok v ekstremnih pogojih visokih voda, kar je zelo velika prednost napram konvencionalnim metodam, ki tega ne zmorejo. Poleg meritve pretoka predstavljamo tudi izračun pretoka suspendiranih sedimentov v vodnem telesu reke Save. Po pregledu podatkov na koncu predstavimo naše splošne ugotovitve, praktične nasvete, ki temeljijo na mnogih meritvah pretoka različnih avtorjev ter prikažemo in obravnavamo nekatere pomembnejših tabel iz programske opreme.In degree we are focusing on theory and usage of acoustic Doppler current profiler for measurement of river flow. Method of getting data is equally important as data, which are needed by institutions or people that are occupied with activities and problems concerning to water. In the begining we shortly presented conventional methods for measuring of discharge. In continuation we are discussing about theory of working of ADCP as well as software programme. Method of measuring with ADCP has got advantages and weaknesses. ADCP is able to measure river flow in extreme conditions of high waters, what is very big advantage in comparison with conventional methods, which can not do that. Beside flow measurement we also presented a calculation of suspended sediment discharge in water body of river Sava. In reviewing the data in the end we are presenting our general findings, practical advices, based on many discharge measurements made by different authors and surveing and discussing about some more important software programme tabulars
