The use of SWAT+ model is increasingly prevalent in the simulation and evaluation of Nature-Based Solutions (NBS) at the catchment scale. Compared to the SWAT model, the SWAT+ model offers several advancements, including enhanced catchment configuration, improved representation of connectivity between man-made hydrologic systems and the catchment stream network, and new algorithms for implementing rule sets for management actions. In this presentation, we outline our methodology and present some preliminary findings from implementing SWAT+ in a South-Eastern Norwegian catchment. The catchment has a relatively large proportion of agricultural land based on Norwegian standards, with several natural lakes. Our modelling results underscore the importance of the spatial configuration phase, particularly in detailed spatial settings and HRU characterization, for simulating catchment-NBS interactions. We found that integrating reanalysis of spatial meteorological data in 1x1 km resolution could significantly improve streamflow simulation. In our case study, by using Met Nordic Reanalysis Dataset from Norwegian Meteorological Institute, the NS efficiency increased from -0.05 to 0.4 prior to any calibrations. Furthermore, we discuss challenges in simulating catchment-NBS interactions with SWAT+, particularly concerning “prospective impact evaluation” in the planning phase of constructed wetlands (design, placement, and optimization).

The impact of tillage-induced temporal variability of soil hydraulic properties on soil water regime was evaluated using measurements and modelling. The measurements were performed in a long-term tillage experiment representing conventional and soil-conserving tillage systems, including no-tillage. It was shown that accounting for the seasonal dynamics of soil hydraulic properties improves the SWAP soil water content simulation results.
