“…The study is framed as purely theoretical as empirical data on microplastic emissions and concentrations were not available. The model is based on an existing hydrobiogeochemical multimedia model, INCAcontaminants [93], with a sediment transport module [95], a rainfall-runoff module [94], and the possibility to add direct effluent inputs from, for instance, WWTPs. It is a lumped model as it assumes homogeneous rainfall and temperature distributions.…”

Contamination with plastic debris has been recognized as one of today's major environmental quality problems. Because most of the sources are land based, concerns are increasingly focused on the freshwater and terrestrial environment. Fate and transport models for plastic debris can complement information from measurements and will play an important role in the prospective risk assessment of plastic debris. We review the present knowledge with respect to fate and transport modeling of plastic debris in freshwater catchment areas, focusing especially on nano-and microplastics. Starting with a brief overview of theory and models for nonplastic particles, we discuss plastic-specific properties, processes, and existing mass-balance-, multimedia-, and spatiotemporally explicit fate models. We find that generally many theoretical and conceptual approaches from This chapter has been externally peer reviewed.The original version of this chapter was revised. An erratum to this chapter can be found at DOI 10.1007/978-3-319-61615-5_14. models developed earlier for other types of (low density) particles apply also to plastic debris. A unique feature of plastic debris, however, is its combination of high persistence, low density, and extremely wide size distribution, ranging from the nanometer to the >cm scale. This causes the system behavior of plastic debris to show a far wider variety than most other materials or chemicals. We provide recommendations for further development of these models and implications and guidance for how fate and transport models can be used in a framework for the tiered risk assessment of plastic debris.

We describe the calibration and application of the Integrated Catchment Phosphorus model (INCA-P) to determine the key factors controlling run-off, sediment and phosphorus (P) losses from a small catchment in southeast Norway. The INCA-P model was parameterized for five land use categories: forest, grassland, urban areas and agricultural areas with and without autumn tillage. Monitoring data from the Norwegian Agricultural Environmental Monitoring Program were used for model calibration at the outlet of the catchment (Skuterud). Available measurements and local expert knowledge were used as reference data on sediment and P loss specific to land uses. We successfully applied the INCA-P model to Nordic conditions: the Nash-Sutcliffe (N-S) statistic, calculated for the calibration period, was 0.82, 0.71 and 0.67 for run-off, sediment and P losses, respectively. For the validation period, the sediment and P losses were slightly overestimated. Scatter plots of observed versus modelled values of run-off, sediment and total P losses indicated that in some cases, the INCA-P model did not adequately represent extreme situations. It is likely that the modelled system behaves in a different way under moderate and large rainfall events, and the model does not represent these. We applied the model to five land use change scenarios to evaluate the possibilities for reducing particle-bound P loads at the catchment outlet. Our results indicate that land use change can lead to more significant reduction in particle and P losses than changes in agricultural practices. The most favourable scenario for freshwater ecosystems would be afforestation: changing half of the agricultural areas to forest would reduce sediment and P losses by 44 and 40%, respectively. Changes in agricultural practice could also improve the situation, especially by reducing areas with autumn tillage to a minimum.

“…Models have been developed for flood flow forecasting (Bergström and Singh, 1995;Vehviläuinen, 2007, and references therein), as tools to better understand the hydrology of well-instrumented catchments Kavetski and Fenicia, 2011;Hrachowitz et al, 2013b) and for simulating pollutant transport and transformations in catchments and surface waters (Whitehead et al, 1998;Wade et al, 2002;Andersson et al, 2005;Andersen et al, 2006;Lindström et al, 2010). The Integrated Catchments (INCA) family of models are widely used for simulating the behaviour of nitrogen (Whitehead et al, 1998;Wade et al, 2002), phosphorus (Crossman et al, 2013a, b), sediment (Lazar et al, 2010), dissolved organic carbon (Futter et al, 2007(Futter et al, , 2009a) and a number of other solutes and pollutants in streams and rivers (Jin et al, 2011;Futter et al, 2012, and references therein). Here we present a new rainfall-runoff model, the Precipitation, Evapotranspiration and Runoff Simulator for Solute Transport (PERSiST) designed for use with the INCA family of models.…”

Abstract. Runoff generation processes and pathways vary widely between catchments. Credible simulations of solute and pollutant transport in surface waters are dependent on models which facilitate appropriate, catchment-specific representations of perceptual models of the runoff generation process. Here, we present a flexible, semi-distributed landscape-scale rainfall-runoff modelling toolkit suitable for simulating a broad range of user-specified perceptual models of runoff generation and stream flow occurring in different climatic regions and landscape types. PERSiST (the Precipitation, Evapotranspiration and Runoff Simulator for Solute Transport) is designed for simulating present-day hydrology; projecting possible future effects of climate or land use change on runoff and catchment water storage; and generating hydrologic inputs for the Integrated Catchments (INCA) family of models. PERSiST has limited data requirements and is calibrated using observed time series of precipitation, air temperature and runoff at one or more points in a river network. Here, we apply PERSiST to the river Thames in the UK and describe a Monte Carlo tool for model calibration, sensitivity and uncertainty analysis.
