Abstract

U ovom diplomskom radu obrađena je hidrologija potoka Jaševice u zadanom profilu Tomići 1. Na
topografskoj podlozi mjerila 1:25 000 definiran je sliv i glavne fizičke značajke sliva. Na razmatranom
slivu Jaševice nema nikakvih meteoroloških i hidroloških mjerenja. Za proračun su, kao ulazni podaci,
korišteni podaci za meteorološku postaju Sisak preuzeti od DHMZ-a i podaci s hidrološke postaje
Gvozd na vodotoku Trepča čiji je vodni režim sličan režimu Jaševice. Obrada meteoroloških podataka
se sastoji od određivanja prosječne godišnje oborine, definiranja maksimalnih intenziteta oborina
različitih povratnih razdoblja za različita trajanja kiše prikazanih kao PTP krivulje. U hidrološku
obradu uključeni su podaci s – u hidrološkom smislu sličnoga sliva Trepče – na osnovi kojih su
definirani: otjecajni koeficijent srednjih voda, prosječni mjesečni i srednji godišnji protok, krivulja
trajanja protoka. Velike vode definirane su maksimalnim protocima i hidrogramima izoliranih velikih
vodnih valova različitih povratnih razdoblja. Maksimalni protoci definirani su na temelju iskustvenih
izraza (metoda V. T. Chowa, Srebrenovićeva formula za male slivove i metoda „četiri koeficijenta“), a
kao mjerodavni usvojeni su prema metodi V. T. Chowa. Hidrogrami izoliranih velikih vodnih valova
definirani su prema metodi R. D. Goodricha. Male vode određene su orijentacijski, a godišnji pronos
nanosa određen je prema Flemingovoj formuli. Na kraju su izvedeni odgovarajući općeniti zaključci o
vodnom režimu Jaševice.

Abstract: The subject of the hydrology of Jaševica stream in default profile Tomići 1 is addressed in this
graduate work. The previously mentioned area and its main features were defined on the topographic
basis in scale of 1:25000. In the analyzed basin Jaševica no previous meteorological and
hydrological measurements were taken. The input data that was used for calculations is the data for
meteorological station Sisak provided by DHMZ and data from hydrological station Gvozd on the
stream Trepča. The processing of meteorological data consists of average annual
precipitation, defining the maximum intensity of precipitation of different return period for
different periods of rain, PTP curve. The data used in the hydrological data processing are – from
hydrological sense similar to the catchment area of Trepča stream – on the basis of which were
determined: runoff coefficient, average monthly and annual discharge, flow duration curves. High
waters are determined by the maximum flow rates and hydrographs of isolated large water waves of
different return periods. Maximum flows are determined on the basis of empirical expressions (Chow's
method, Srebrenović formula for small catchment area and “four coefficients” formula). The
hydrographs of isolated large water waves are determined by the method of R. D. Goodrich.
Small waters are shown approximately, while the annual sediment transport is determined by the
Fleming formula. Finally, general conclusions are drawn about the water regime of Jaševica stream.
