Sekundarni naslov:	Sustainable measures to slow down the flow of water
Sekundarni povzetek:	This diploma paper discusses the hydraulic analysis in case of flooding in a given area of river Kokra. It discusses the problems of erosion processes that occur at the onset of high water. Hydraulic analysis of the area was made by using hydraulic tools HEC-RAS for flows Q5, Q20, Q50, Q100, Q500 and normal medium flow. With hydraulic analysis is in the foreground the calculation of velocity and shear forces that occur in the river and on floodplains. With the help of software tools ESRI ArcGIS and extension HEC-GeoRAS are, based on hydraulic analysis and taking into account the different return periods of high water, certain flood and erosion hazard maps. Based on erosion hazard map at a flow rate Q100, are located most critical points in this area. After carrying out a hydraulic analysis are also presented measures for improving the situation in the river and on floodplains next to it. The focus of the diploma is on the socalled sustainable measures, which at the same time with different requirements equivalent to take into account the environmental aspect.

Povzetek (ePrints):	V diplomski nalogi je obravnavana hidravlična analiza v primeru visokih voda na izbranem območju reke Kokre. Predstavljena je problematika erozijskih procesov, ki se pojavijo ob nastopu visokih voda. Hidravlična analiza obravnavanega območja je izvedena s pomočjo hidravličnega orodja HEC-RAS za pretoke Q5, Q20, Q50, Q100, Q500 in normalni srednji pretok. Pri hidravlični analizi je v ospredju izračun hitrosti in strižnih sil, ki se pojavijo v vodotoku in na poplavnih območjih. S pomočjo programskega orodja ESRI ArcGIS in programskega dodatka HEC-GeoRAS so na podlagi hidravlične analize in ob upoštevanju različnih povratnih dob visokih voda določene karte poplavne in erozijske nevarnosti. Na podlagi karte erozijske nevarnosti pri pretoku Q100, so locirana najbolj kritična mesta na obravnavanem območju. Po izvedeni hidravlični analizi so predstavljeni tudi ukrepi za izboljšanje stanja v samem vodotoku in na poplavnih ravnicah ob njem. Poudarek v diplomi je na t. i. sonaravnih ukrepih, ki hkrati z različnimi tehničnimi zahtevami enakovredno upoštevajo tudi ekološki vidik.
