Applicability of the HEC-HMS model for continuous runoff simulations
Mogućnosti za primenu modela HEC-HMS za kontinualne hidrološke simulacije
Апстракт
To examine the applicability of the HEC-HMS software for continuous runoff simulations, efficiencies of three different HEC-HMC models are assessed. The first and the second models are lumped ones, based on deficit and constant loss model and (more complex) Soil Moisture Accounting (SMA) loss model, respectively, whereas the third model is the semi-distributed version of the first one. In this way, the impact of the increase model structural complexity and parameter spatial disaggregation on model's ability to reproduce observed flows can be estimated. The models are calibrated against flows observed at the Beli Brod stream gauge. Model efficiencies are quantified in terms of relative bias, correlation coefficients and Nash-Sutcliffe efficiency coefficients for both, flows and the logarithms of flows. Also, model performance is estimated by visual comparison between simulated and observed hydrographs. The results indicate certain HEC-HMS's disadvantages and limitations to the applicati...on for continuous runoff simulations.
U ovom radu su analizirane mogućnosti paketa hidroloških modela HEC-HMS za kontinualne hidrološke simulacije poredenjem rezultata tri različito postavljena modela sa osmotrenim hidrogramima. Modeli su formirani za sliv reke Kolubare do hidrološke stanice Beli Brod. Slaganje simuliranih i osmotrenih hidrograma kvantifikovano je preko nekoliko pokazatelja kvaliteta modela. Rezultati u ovom radu ukazuju na neke nedostatke i ograničenja HEC-HMS-a u primeni za kontinualne hidrološke simulacije.
