A realistic depiction of the network performance can only be attained by considering demands to be pressure dependent. In this context, the assumption that all demands are fully satisfied regardless of the pressure in the system becomes unreasonable and represents the main limitation of the conventional demand driven analysis (DDA) approach to WDS modelling. When a network is lacking in pressure, not all consumer demands will be met in full. In water distribution systems (WDSs), the available flow at a demand node is dependent on the pressure at that node. ![]()
