D-Flow 1D Pipes

This programme uses the complete de Saint Venant Equations, thus including backwater and transient flow phenomena. It models a wide variety of cross sections and manhole shapes (including user-defined ones) and allows you to build up your own cross section and manhole database. It is specially designed to handle large and complex sewer networks on an ordinary PC, where the computation time is only linear with the size of the network and independent of its complexity. The hydrodynamic 1D/2D simulation engine has an automatic drying and pressurised procedure and handles real supercritical flow and is always 100% mass conservative. It uses a self-selecting time step so your computer will not crash and accuracy is guaranteed. All possible boundary conditions can be specified by you or are automatically applied. You can specify virtually any type of hydraulic structure, such as single or multiple stage pumps, weirs of any shape, rectangular and circular gates, culverts and basins. All structures handle free, submerged and transient flow conditions.

The D-Flow 1D Pipes programme includes rainfall runoff inflow, dry weather flows and the processes for various types of paved areas, such as streets, roofs and parking lots. You may define your own time and spatially varied rainfall pattern, or historical data of storm events and long time series with or without dry periods. Detailed infiltration as a time-dependent process following the HORTON equation is also available. Real-time control options, including PID control, are available for all structures and are ideal for complex centralised control systems using rainfall predictions. Sediment transport computation shows where sediment might be deposited; interfaces completely with the D-Flow 1D Open Water programme to provide an integrated model of the urban water system and its environment.

Programmes

SOBEK allows you to simulate the interaction of water and water related processes in time and space. The suite is mostly used for the modelling of integrated water systems for water management, design, planning and policy making. SOBEK consists of a number of well-tested and validated programmes, which are linked to and integrated with one-another. These programmes are:

D-Flow 1D Open Water
D-Flow 1D Pipes
D-Flow 2D Overland
D-Rainfall Runoff Open Water
D-Water Quality 1D
D-Real Time Control.
