Table C - 1. Water Quality (WQ) Parameter by WQ Library: Temperature Simulation Module, Nutrient Simulation Module I (NSMI), and General Constituent Simulation Module (GCSM). The Parameters are identified by the group, the name or definition, and the units. Each parameter includes the default base value (or default method selection) and theta (Ѳ). Theta (Ѳ) indicates that the parameter is a temperature-dependent coefficient (specified at 20 degrees Celsius).
