The Sewer block library of SIMBA has been completely redesigned: SIMBA 5.0 now provides the choice between two approaches of sewer system modelling concepts, differing in their level of complexity. – Now you can choose between hydrological (simplified) and hydrodynamic (detailed) sewer system modelling approaches – it is even possible to combined these two within one model:

Generic blocks:

• Input of rainfall data files, including non-uniform distribution of rainfall across the
       sewer network
• Specification of dry weather flow properties – globally and individually for
       sub-catchments
• Definition of sub-catchments, including inflows from extraneous sources
• Integration of arbitrary rainfall runoff and surface runoff models for pervious and
       impervious areas
• Dedicated input and output blocks for long-term simulations
• Easy integration of sewer system, WWTP and river models: Truly integrated
      simulation
• Integration of control

Blocks for simplified (hydrological) modelling of sewer systems:

• Translation of flows and pollutants within the system
• Model block for five different types of storage and overflow structures (according to
       German A128 guidelines)
• Pollutants originate from three sources: dry weather flow, rainfall runoff,
       extraneous inflows
• Any number of pollutants
• Complete mixing of pollutants with optional sedimentation in on-line tanks
• Generic script for easy generation of reports and graphical outputs
• Very fast simulation with discrete time steps

Blocks for complete hydrodynamic sewer simulation:

• Based on the most recent version (Version 5) of the Storm Water Management
       Model (SWMM) of the US Environment Protection Agency
• User-friendly input of sewer systems
• Detailed hydrodynamic simulation of sewer systems by solution of the complete
       Saint Venant differential equations
• Modelling of wastewater and pollutant transport also within large sewer systems
• Simulation of any biochemical transformation processes by integration of SIMBA
       water quality models (FOX models in Petersen matrix notation) – fully integrated
       in hydrodynamic flow simulation
• Any number of pollutants
• Within each pipe: water and sediment phase can be modelled
• User-friendly interfaces to other SIMBA blocks
• Arbitrary inputs (inflows, control inputs)
• Arbitrary outputs (flows, water levels, concentrations, …)
• Display of results also by animated plan view and longitudinal profiles
• Hydrodynamic modelling of rivers, including arbitrary river water quality
       processes, also possible
