UCODE
UCODE_2005 and six post-processors are included in this distribution. These programs can be used with existing process models to perform sensitivity analysis, data needs assessment, calibration, prediction, and uncertainty analysis. Any process model or set of models can be used; the only…

Multi-Model Analysis (MMA)
The Multi-Model Analysis (MMA) computer code can be used to evaluate results from alternative models of a single system using the same set of observations for all models. As long as the observations, the observation weighting, and system being represented are the same,…

MODSIM
MODSIM is a comprehensive, generalized river basin management decision support system (DSS) under continuous development and enhancement since 1979 at Colorado State University. MODSIM is designed to be flexible and robust, allowing a wide range of analyses from short-term daily operations requiring hydrologic flow routing…

RiverWare
RiverWare® is a general river and reservoir modeling tool for operational scheduling and forecasting, planning, policy evaluation, and other operational analysis and decision processes. RiverWare has the capability to model: (1) Hydrology and hydrologic processes of reservoirs, river reaches, diversions, distribution canals, consumptive uses,…

The Water Rights Analysis Package (WRAP)
The WRAP modeling system simulates water resources development, management, regulation, and use in a river basin or multiple-basin region under a priority-based water allocation system. The model facilitates assessments of hydrologic and institutional water availability and reliability in satisfying requirements for municipal, industrial, and…
-
Diffusion Analogy Flow Model (DAFLOW)
The model provides a time series of discharge, flow area, top width, and tributary inflow at node points along a system of one-dimensional open channels. The time series of hydraulic variables can be used as input hydraulics by a transport model, such…

MOdel for Urban SEwers (MOUSE)
MOUSE is a comprehensive modeling system for analysis of urban drainage and sewer systems including links to GIS. MOUSE simulates spatial variations in flows, water levels, sediment transport and pollution in pipes and open drains. MOUSE can be used for the prediction of…

Physical Habitat Simulation (PHABSIM)
The purpose of the Physical Habitat Simulation System (PHABSIM) is to simulate a relationship between streamflow and physical habitat for various life stages of a species of fish or a recreational activity. The basic objective of physical habitat simulation is…

Hydraulic Models
Hydraulic models are mathematical models of a fluid flow system such as a water system, a sewer system, or a storm system, and are used to analyze systems’ hydraulic behavior. Hydraulic models illustrate the effects of changing demand and climactic conditions…

Water Quality Models
Water Quality Models included in this inventory are generally used in the prediction of water pollution using mathematical simulation techniques. In most cases, these models simulate runoff or streamflow and calculate the position and fate of water quality parameters. Some models described hereafter…
