Introducing node waterage as constraint of optimal operation and EPANET 2.
引入节点水龄作为优化调度的约束条件，以EPANET 2。

To calculate the waterage in the urban water supply and distribution network, a simplified and junction by junction algorithm based on the definition of the waterage itself is designed.
基于水龄的定义，设计逐节点遍历简化算法计算供水管网节点水龄。

For example, as the great ice sheets that covered North America during the last ice age steadily melted away, huge volumes of water flowed from them.
