Exchangeable Phosphorus Pools and Equilibrium Characteristics for River Sediment as a Function of Particle Size

Abstract

The System-Wide Water Resources Program-Nutrient Sub-Model (SWWRP-NSM) represents a library of algorithms for simulating nutrient cycling, transformation, and flux in terrestrial and aquatic systems. One feature of SWWRP-NSM is the capability of simulating phosphorus (P) equilibrium fluxes between exchangeable particulate and soluble P pools in the aquatic water column as a function of particle size class. The objectives of this research were to quantify exchangeable particulate phosphorus (P) pools and equilibrium with soluble P as a function of river sediment particle size distribution for use in initializing model parameters for simulating P adsorption and desorption in river systems.
