Abstract
Problem koji se javlja prilikom dimenzioniranja sustava površinske odvodnje je određivanje geometrije pojedinih kanala u kanalskoj mreži s optimalnim nagibom i poprečnim presjekom. Ovim radom će se za proračun koristiti softver za modeliranje tečenja u otvorenim vodotocima te se ispitati njegova prikladnost za rješavanje definiranog problema. Izračun otjecanja s pojedinačnih parcela je izračunano u diskretnim točkama na ušćima kanala IV. reda pomoću modela HEC-HMS. Na temelju topografije terena položena je mreža kanala III., II. i I. reda, pri čemu će se okvirno definirati njihov uzdužni nagib. Proračun se provodi promjenom dubine i nagiba kanala III., II. i I. reda sve dok se ne uspostavi tečenje bez uspora, tj. dok se ne optimizira geometrija kanala. Cilj rada je utvrditi da li su rezultati matematičkih modela pouzdani kada se on primijeni na složenu mrežu kanala koji imaju niveletu na različitim visinskim kotama.
Abstract (english)
Goal in surface drainage system dimensioning process is to determine the geometry of individual channels in the channel network with an optimal geometry and slope. Flow modeling software for open channels is used for the hydraulic calculations during which its suitability for the defined problem is evaluated. The calculation of runoff from individual plots was calculated at discrete points at the outlets of the detailed channels using the HEC-HMS model. Based on the topography of the terrain, approximate slope of the canals in the network is defined. The flow calculation is performed by adjusting the depth and slope of the channels until a flow without backwater effect is established, i.e. until the channel geometry is optimized. The aim of this paper is to determine whether the results of mathematical models are reliable when applied to a complex network of channels that have a inlets/outlets at different elevations.
