WebSummaryPSYCHIC is a process-based model of phosphorus (P) and suspended sediment (SS) mobilisation in land runoff and subsequent delivery to watercourses. Modelled transfer pathways include release of desorbable soil P, detachment of SS and associated particulate P, incidental losses from manure and fertiliser applications, losses from hard standings, … WebJun 11, 2024 · Nitrogen (N) and phosphorus (P) are the two most important nutrients contributing to eutrophication, with the latter generally of most concern in freshwater systems. Excessive sediment accumulation in the substrates of rivers, lakes and aquatic habitats is also adversely affecting habitat suitability for certain rooted plants, including ...
