Spill of Soluble, High Density, Immiscible Chemicals on Water

摘要

A computer program for simulating the spill of heavy (rho greater than 1), immiscible chemicals into rivers and streams is presented. The information provided by the model includes the length and width of the on-bottom contaminated area, the cup-mixing concentration profile at the spill site, and the dissolution lifetime of the chemical. If preferred, the mass of chemical remaining on bottom at any time may be obtained in addition to the cup-mixing concentration information. Inputs into the program include general spill and stream information and pertinent chemical and physical properties of the substance spilled. Verification of the model via comparison with data obtained from both laboratory simulations and documented spills is also presented.
