URBAN INFRASTRUCTURE MODELLING

摘要

The practical application of a simulation modelling for large size urban drainage systems is subjected to a number of simplifying assumptions, constrains and bottlenecks which require a high level of user abstraction and interpretation on a side of project team and the client. A good technical formulation of project tasks as well as a proper schematisation of a system structure and process is the essential milestone for a successful completion of the project. In the same moment numerical modelling of water supply and water distribution systems has become a standard and an inevitable practice in any serious attempt of evaluating hydraulic, water quality, and economic aspects of these complex systems. Modelling capacity of well-suited models, featuring advanced technologies including linking the models to GIS systems and telemetry systems, accurate fire flow calculations, water quality analysis, and leakage reduction is incomparable with any alternative approach for these purposes. Hydraulic modelling of water supply and water distribution network is used for planning linking-up consumers to the network and evaluating the remaining capacity of the network, modelling of network's breakdown, modelling of various loading and operational states of the system including fire flow analysis, reconstruction of existing and planning of new pipes, pressure zone optimisation, leakage reduction and others.
