Abstract
Phosphorus (P) adsorption-desorption behaviors on the airborne dust have been investigated by using simulation with numerical modeling. Dust samples were collected during summer 2011 along coastline of Kuwait Bay. Dust storms results showed that substantial nutrients increase in Kuwait Bay which is led to, subsequently, frequent algal blooms and ecological stress. Numerous physical processes give rise to nutrient levels including sediment adsorption/desorption processes. This correlation was incorporated into a three-dimensional hydrodynamic model (Delft3D-FLOW) and a 3D water quality model (Delft3D-WAQ), originated by Deltares, the Netherlands and was linked to a sediment transport model. Simulations showed an enhanced prediction of dissolved phosphorus in Kuwait Bay during the last dust storm in 2011.
