Comparison of simulation results using HYDRUS-1D and model in CGMS for selected region GRID50 of the Czech Republic

Original language description

CGMS (Crop Growth Monitoring System) developed by JRC is an integrated system to monitor crop behaviour and quantitative crop crop yield forecast that operates on a European scale. To simulate water balance in the root zone the simulation model CGMS-WOFOST(Supit a Van der Gott 2003) is used that is based on water storage routing. This study was performed to assess a possible impact of simplifictions of the water storage routing based model on simulated water regime in the sil profile. Results of CGMS-WOFOST are compared with results of a more precise Richrards equation based HYDRUS -1D (Šimůnek et al. 2005). 16 scenarios are simulated using HYDRUS-1D. Each scenario represents a single soil profile presented in the selected cell of GRID 50 in the CzechRepublic. Geometry of the soil profiles, material (texture) definition, root distributions, measured daily rainfall, calculated daily evaporation from the bare soil surface and transpiration of crop canopy were defined similarly to CGMS-W
