It is generally known that water supply systems consist of the following basic components: water source, water treatment plant, reservoirs, supply and main pipelines, and water supply network.

Depending on the terrain configuration and users distribution, the water supply network can usually be of branch type, loop type or combined. The water supply network in the urban areas is mostly a loop type network, whereas in the rural – outskirt areas, there is a branch type network.

Subject of this hydraulic analysis is to comprehend the influence of branch density in the branch water supply network on the size and distribution of water hammer in the network.
