Amethod has been developed to simulate the long-term migration of radionuclides in the near-surface of a river catchment, following their release from a deep underground repository for radioactive waste. Previous (30-year) simulations, conducted using the SHETRAN physically based modelling system, showed that long-term (many decades) simulations are required to allow the system to reach steady ...

Despite recent progress in terms of cheap computing power, the application physically-based distributed (PBD) hydrological codes still remains limited, particularly, because some commercial-license are expensive, even under academic terms. Thus, there is a need for testing performance free-license PBD simulating complex catchments, so that and reliable mechanistic modelling alternatives might b...

The SHETRAN physically-based distributed rainfall-runoff modelling system gives detailed simulations in time and space of water flow and sediment and solute transport in river catchments. It is therefore a powerful tool for studying hydrological and environmental impacts associated with land-use and climate change. A Graphical User Interface (GUI) has been developed that allows a catchment data...

Abstract The knowledge of spatio-temporal dynamics soil moisture within the catchment is very important for rainfall–runoff modelling in flood forecasting. In this study comparison between remotely sensed and estimated from SHETRAN hydrological model was performed small flashy Jičinka River (75.9 km 2 ) Czech Republic. Due to a relatively coarse spatial resolution satellite data, data were down...

Recent extensive water quality surveys in Ireland revealed that diffuse phosphorus (P) pollution originating from agricultural land and transported by runoff and subsurface flows is the primary cause of the deterioration of surface water quality. P transport from land to water can be described by mathematical models that vary in modelling approach, complexity and scale (plot, field and catchmen...
