This book incorporates selected topics on theory, revision, and practical application models for water supply systems analysis. A water supply system is an interconnected collection of sources, pipes, and hydraulic control elements (., pumps, valves, regulators, tanks) delivering consumers prescribed water quantities at desired pressures and water qualities. Such systems are often described as a graph, with the links representing the pipes, and the nodes defining connections between pipes, hydraulic control elements, consumers, and sources. The behavior of a water supply system is governed by: (1) the physical laws which describe the flow relationships in the pipes and the hydraulic control elements, (2) the consumer demands, and (3).
