Modeling of Gravel Mining in the Rio Salado, Arizona
Publication: World Environmental and Water Resources Congress 2008: Ahupua'A
Abstract
Impact of sand and gravel mining on flood zone coverage and riverbed change of the Rio Salado, Salt River, Phoenix, Arizona were simulated using CCHE2D, a depth-averaged two-dimensional hydrodynamic and sediment transport model developed at the University of Mississippi. The bed material was treated as three layers on the channel bed with multiple grain-sized sediment mixtures. Changes in bed elevation were calculated by solving the sediment mass conservation equation. The calculated results showed that the two-dimensional model was applicable in simulating the impact of sand and gravel mining on flood zone coverage and channel geomorphology changes.
