Hydrosim V Overview

Thoroughly updated and upgraded, the new Hydrosim V has a wider application and is more versatile, user-friendly and time-efficient than its predecessors. At the same time the program has retained enough of its previous features to enable users to upload their existing MS-DOS-based Hydrosim files without loss of continuity in ongoing projects.

The program can be used either as a standalone hydrological package, or integrated directly into the ModelMaker and PipeMaker suites. It is also fully integrated into IMQS (Infra-Structure Management Query Station).

Hydrosim V employs the kinematic method to compute overland runoff – generally accepted as being the most accurate mathematical representation of the rainfall-runoff process.

Design rainfall can be generated based on regionalised parameters, such as Inland/Coastal Region and Mean Annual Precipitation. Rectangular, triangular and Chicago-type synthetic storm patterns are available. Alternatively, the user can input coefficients from standard IDF curves for synthetic rainfall, or else a user-provided hyetograph.

The program can accommodate existing as well as new drainage elements. The required pipe diameters or flow depths in channels can be output in the case of elements that need to be designed, and the volume of temporary storage is given where an existing element is undersized and no overflows are allowed.

The dual drainage concept is modeled in the case of overflows, so that the user can determine the depth of flow in overflow channels for recurrence intervals in excess of the design recurrence interval adopted for the formal drainage system.

A reservoir routing option allows the user to insert one of more reservoirs at selected locations in the network, to model the effects of flood routing through detention storage.

The option of integrating Hydrosim V into ModelMaker enables CAD interfacing with plan data and screen input of topographical data such as catchment areas, overland flow lengths and slopes, as well as drainage element data.

Integrating Hydrosim V with PipeMaker extends the suite's capabilities to computing quantities for pipe networks.

Hydrosim V can handle a number of elements limited only by the hardware configuration.

Hydrosim V is fully integrated into IMQS where it forms the stormwater module alongside the existing WADISO water distribution and SEWSAN sewer analysis modules. This clearly offers significant benefits to regional authorities regarding stormwater management policies and their implementation.
