Based on state-of-the-art software technology, WESTforIUWS allows for:

• Exploration of specific water quality scenarios developed by the system manager (e.g. flow diversions, introduction of tanks, changes in operation)
• Automatic optimization of the operating parameters
• Performing short-term and long-term evaluations
• Uncertainty and sensitivity analysis of the model to spot the most influential operating parameters and to assess the risk of non-compliance with regulations

Features:

• Plant layout set-up (unlimited size and complexity) using the extended model and components library (including components for sewer, WWTP and surface water)
• Dynamic and interactive simulation runs
• Graphic display of data during simulation runs
• Linking with GIS systems
• Model Editor
• Custom model development
• Full editing capabilities for the processes and components in the Gujer (Petersen) Matrix
• Parameter estimation
• Parameter estimation based on comparison of simulated data with measured values
• Multi-criteria optimization
• Scenario analysis
• Automatic execution of a set of simulations with different parameter values
• Parameter and range selection
• Parameter values can be manually placed, automatically spaced (linearly or logarithmically) or sampled from standard statistical distributions
• Sensitivity analysis
• Calculation of the absolute or relative local sensitivity of a variable towards a change in a certain parameter
• Calculation of global sensitivity by means of Monte Carlo simulation
• Automatic determination of the important model parameters
• Uncertainty analysis
• Automatic execution of a Monte Carlo simulation in order to evaluate uncertainty in the model predictions
