Methodology
Modelling Approach
Nutrient Runoff Cascade
Simulates forest sponge interception (Ia = 15mm) and landcover runoff metrics (Q = Σ Ci I Ai) to map nutrient loads delivered to basins during high-rainfall weather events.
Thermodynamics of Calcium-P
Calculates the Saturation Index (SI = log10(IAP / Ksp)) of calcium phosphate precipitation to assess the bio-availability of total phosphorus (TP) for algae consumption.
Stochastic Risk Forecasts
Executes a 1,000-trial Monte Carlo simulation to vary inputs (±10%) under weather extremes, estimating the statistical probability of Trophic State transitions and harmful blooms.
