The feedback between varying ecohydrologic conditions and biogeochemistry in wetlands remains a significant challenge in environmental modeling. We explored the effect of climate and nutrient load on wetlands using a mechanistic biogeochemical model that integrates carbon, nitrogen, and sulphur cycles (BAMS4). The model was initially validated at site specific conditions and it was then extended to a spatial scale. Our results show a relative high resilience to climate change and variability with nutrient load.
