Abstract: The RECOVERY model was developed by Boyer et al (1994). The model is a PC-based screening-level model to assess the impact of contaminated bottom sediments on surface waters. Because of lack of spatial resolution capability, the RECOVERY model may not be appropriate for bays and estuaries where, generally, hydrodynamic dispersion and transport are important both in magnitude and spatial variations. Therefore, we have modified and implemented the original single-box RECOVERY model into a multi-box version, the Multi- RECOVERY model. Similar to the original RECOVERY model, the Multi-RECOVERY model is a PC-based with a Graphic User Interface (GUI) module to make the use of the model user-friendly. The program allows the user to generate and analyze, through GUI, recovery scenarios for remediation of contaminated sediments. The functionality of the implemented Multi-RECOVERY model (with ten boxes) is tested using a designed scenario and the sensitivity analysis for the Multi-RECOVRY model has also been executed. Simulation results for the Multi-RECOVERY model are compared and identified with those of the original RECOVERY model for a single-box case.
