Abstract: The purpose of this Ecosystem Management and Restoration Research Program (EMRRP) technical note is to document the application and evaluation study of the Hydrologic Engineering Center-River Analysis System-Nutrient Simulation Module I (HEC-RAS-NSM I) model for the Lower Minnesota River. HEC-RAS is a one-dimensional (1D) riverine hydraulic model that can be used to analyze flows and sediment transport (HEC 2010a, 2010b). A new nutrient water quality module — NSM I — was developed for the HEC-RAS model. The NSM I was designed to simulate aquatic dissolved oxygen, carbonaceous biological oxygen demand, nitrogen and phosphorus cycles, and algae biomass with simplified processes and minimum state variables. The processes and formulations in NSM I is adapted, in part, from the Enhanced Stream Water Quality Model (QUAL2E) (Brown and Barnwell 1987), its improvements (Chapra et al., 2008), and the one-dimensional (cross sectionally averaged) hydrodynamic and water quality model (CEQUAL-RIV1) (EL 1995). The HEC-RAS-NSM I model could be utilized for US Army Corps of Engineer’s (USACE’s) water resources management and ecosystem restoration.
