ESM 222 Fate and Transport of Pollutants in the Environment Lab #7: Rate Limited Transfer of Mass Report due 05/30/08 Objective: Understand the use of numerical models for modeling rate-limited transfer of mass between environmental compartments. We will use EQC Level III. EQC Level II and III build on the equilibrium distribution model EQC Level I, but allow mass to transfer in and out of certain compartments at rates determined by the user, through external calculations. From the modeler’s website: “A Level III simulation describes a situation which is one step more complex and realistic than the Level I or II model. Like the Level II model, chemical is continuously discharged at a constant rate and achieves a steady state condition in which input and output rates are equal. The loss processes are degrading reactions and advection. Unlike the Level II model, equilibrium between media is not assumed…Mass balances are calculated for the four bulk media of air (gas + aerosol), water (solution + suspended sediment + biota), soil, (solids + air + water), and sediment (solids + pore water). Equilibrium exists within, but not between media. For example, sediment solids and pore water are at equilibrium, but sediment is not necessarily at equilibrium with the overlying water.” Methods: A) EQC Level III The EQC Level III model is available in the ESM 222 course folder: Courses\Spring2006\ESM222\Level III. Copy it to your H drive and use it there.
