Abstract
Diplomsko delo predstavlja teoretične osnove analize krivulj upadanja, katere se uporabljajo za opisovanje dinamike upadanja pretokov. V prvem delu strokovne naloge je predstavljeno teoretično ozadje komponent hidrograma. Predstavljene so tudi metode upadanja pretoka ter nova metoda, s katero dobimo odzivnostno funkcijo porečij, katera odraža odzivnost povodja na spremembe zaloge vode v porečju. V drugem delu je uporabljena nova metoda. Izvedena je analiza na dveh eksperimentalnih porečjih hudournikov Mačkov graben in Kuzlovec, kjer so uporabljeni podatki padavin in pretokov. Naša naloga je bila določiti krivuljo upadanja za oba vodotoka in z oceno le-teh dobiti odzivnostno funkcijo ter ju primerjati. Z novim pristopom ponazorimo, kako lahko uporabimo časovno zaporedje spremenljivosti vodnega toka za razlago povezave med zalogo vode v porečju in pretokom v strugi vodotoka. Prav tako lahko funkciji nadalje uporabimo za karakterizacijo porečja ter za simuliranje celotnega spektra hidroloških pogojev. Še zlasti je nova metoda uporabna za natančnejšo oceno zaloge vode v prispevnem območju, čas upadanja pretoka ter odzivnost porečja na padavine.

Title:Methods for analyzing the discharge recession dynamics
Abstract:
Graduation thesis presents theoretical basis for classical hydrograph recession curve analysis which are used to describe the dynamics of discharge recession. The first part of the thesis presents theoretical background on assessing different components of hydrographs. A new method which foresees the extraction of catchment sensitivity function is presented. In the second part of the thesis, New method is applied on rainfall and discharge data from two experimental catchments, the Mačkov graben and Kuzlovec torrents. Our task was to determine the periods of discharge recession for both stream, to get sensitivity function and compare them. The new approach demonstrated how streamflow time series can be used to construct a storage–discharge relationship which could be used for catchment characterization and to simulate the entire spectrum of hydrological conditions. In particular, the method leads to possible further quantitative estimates of catchment dynamic storage, recession in different time scales, and sensitivity to rainfall inputs.

Keywords:hydrograph, discharge, recession curve, baseflow, sensitivity function
