摘要

The 1D model package STRIVE is verified for simulating the interaction between ecologicalnprocesses and surface water flow. The model is general and can be adapted and furtherndeveloped according to the research question. The hydraulic module, based on the Saint-Venantnequations, is the core part. The presence of macrophytes influences the water quality and thendischarge due to the flow resistance of the river, expressed by Manning’s coefficient, and allowsnan ecological description of the river processes. Based on the advection–dispersion equation,nwater quality parameters are incorporated and modelled. Calculation of the water quantitynparameters, coupled with water quality and inherent validation and sensitivity analysis, is thenmain goal of this research. An important study area is the River Aa near Poederlee (Belgium), anlowland river with a wealth of vegetation growth, where discharge and vegetation measurementsnare carried out on a regular basis. The developed STRIVE model shows good and accuratencalculation results. The work highlights the possibility of STRIVE to model flow processes, waternquality aspects and ecological interaction combined and separately. Coupling of discharges, waternlevels, amount of biomass and tracer values provides a powerful prediction modelling tool for thenecological behaviour of lowland rivers.
