本powerpoint演示文稿首先简要概述了休斯顿市的供水系统。介绍了水质建模的主题，包括影响区地图——平均日需求、水龄结果——平均日需求、投诉和影响区，2005年，以及三卤甲烷形成结果——平均日。有关储罐建模的主题包括储罐混合——计算流体力学、减小入口直径改善储罐混合、最大化进水长度改善储罐混合、地表水和地下水填充时良好混合、关闭地下水供应时低于最佳混合、，当流量进一步减少并使用两个入口时，分层和混合不良。单向冲洗（UDF）的主题包括UDF观测和管道刻度。

This powerpoint presentation begins by providing a brief overview of the City of Houston's water distribution system. The topic of water quality modeling is presented and includes a map of zone of influence - average day demand, water age results - average day demand, complaints and zones of influence, 2005, and trihalomethane formation results - average day. Topics presented on storage tank modeling include storage tank mixing - computational fluid dynamics, reducing inlet diameter improves storage tank mixing, maximizing the inflow water length improves tank mixing, good mixing when filled by both surface water and groundwater, less than optimal mixing when groundwater supply is turned off, and stratification and poor mixing when the flow is further reduced and two inlets were used. The topic of unidirectional flushing (UDF) covers UDF observations, and pipe scale.
