| Abstract: | The type of leakage network in water pipe network was introdued.The leakage volume model and estimation methods of pipe network node were analyzed.A new leakage volume estimation method was established based on the tool of GIS network.The study focused on pipeline networks topology relation.The amount of pipe network node leakage volume was estimated by using DEM to caculate network nodes elevation and the leakage model method.It was proved that it was an efficient way to estimate the amount of leakage based on GIS pipeline network nodes by example. |
| Keywords: | water pipe network leakage volume model network topology GIS digital elevation model(DEM) |
