Abstract (croatian)
STREAM 1D je računalni model za prognoziranje hidrodinamičkih procesa u izrazito uslojenim uvjetima. Procesne jednadžbe izvedene su iz zakona očuvanja mase i količine gibanja za jednodimenzionalno i nestacionarno tečenje dva sloja plitkih voda različitih gustoća u koritima proizvoljne geometrije. Numerički algoritam implementiran je u Python 3.6 programskom jeziku, a temelji se na metodi konačnih volumena, odnosno dobro uravnoteženoj Roevoj Q-shemi. Model je detaljno validiran usporedbom s terenskim mjerenjima za slučaj dvoslojnog tečenja na ušću Rječine. U ovome su radu prikazane mogućnosti modela u prognoziranju duljine prodora slane vode uslijed konstantnog protoka rijeke. Uz kalibrirani koeficijent trenja na razdjelnicu među slojevima, poklapanja numeričkih rezultata i izmjerenih vrijednosti su zadovoljavajuća.
Abstract (english)
STREAM 1D is a computational model for simulating hydrodynamic processes in highly stratified conditions. Governing equations are derived from the conservation laws for mass and linear momentum, for one-dimensional and time-dependent shallow water flow of two-layer of different densities and in channels with irregular geometry. The numerical algorithm is implemented in Python 3.6, and is based on the finite volume method, or more precisely on a well-balanced Q-scheme of Roe. This model was thoroughly validated by comparing the results with field measurements of two-layer flow in the Rječina River Estuary. In this work, we present the model’s capability to predict the salt-water intrusion length under constant river flow. When the interfacial friction factor between the layers is calibrated, the agreement between the numerical results and measured values is satisfactory.
