Pipe networks are comprised of not only pipes, but manholes, junctions, drop structures, inlets, outlets, pumps, and other controls, all affecting the flow of water. Modelling these networks is challenging due to: 1. The wide range of complex hydraulic phenomena that influence the flow and how to represent this complexity and the associated energy losses within a 1D solution, along with the interaction of pipe network flows with above ground flooding at inlet/outlet locations. 2. The physical complexity of the pipe network, and the oftentimes poor data quality, or lack of data, making construction of models difficult. As citywide urban stormwater pipe networks can be made up of 10’s of thousands individual elements, manual quality control checks of urban pipe network datasets can therefore be very onerous and time consuming. The first part of this webinar discusses the key hydraulic calculations and capabilities that are needed to replicate real-world flow behaviour in pipe network systems. The second part focuses on GIS tools for: maximising workflow efficiency during the data quality control review; automated data correction options; and efficient hydraulic results checking for 1D stormwater pipe network and 2D above-ground inundation models.
