River Flood Lines Prediction With 1D Open Channel Flow Model

Authors:

Abstract

Numerical modelling is becoming standard practice for river flood lines prediction among other procedures in flood mitigation planning. 1D open channel flow model has shown to be optimal for large scale natural watercourses modelling thus it was used for flood lines prediction in the entire Croatian region of Gorski kotar where total length of modelled watercourses amounted to 108 km. Software package Stripp12 used for river flow and flooding simulation was employed for unsteady water wave propagation simulations, as opposed to classic steady state simulations of peak discharge flow regime.
