Appendix B. Explanation of Defaults and Alternative Values Representing Abiotic Characteristics of Aquatic Ecosystem

Abiotic characteristics of the aquatic ecosystem that are necessary for KABAM are defined in Table 4 of the model tool. These characteristics include concentrations of particulate organic carbon (XPOC), dissolved organic carbon (XDOC), dissolved oxygen (COX), suspended solids (CSS), water temperature (T), and % organic carbon (OC) content of the sediment. The model tool is populated with default values for these parameters, which can be altered based on the needs of the model user. Default values are based on the abiotic characteristics of the aquatic ecosystem and are designed to be consistent with the OPP standard pond scenario used in EXAMS. Brief explanations for these default values as well as guidance on selecting alternative values are provided below for each parameter.
