PREDICTING THE CLOGGING OF STORM WATER INFILTRATION SYSTEMS

渗透系统广泛应用于城市和农村地区的雨水可持续管理。它们也是大型雨水收集设施的组成部分。然而，它们往往因堵塞而失效（入渗介质被径流中的泥沙填满），这一现象尚不清楚。本项目的目的是开发一种新的雨水入渗系统堵塞预测方法。将进行广泛的一维和二维实验室实验计划。在渗透系统中发生的单元过程的模型将被定义/开发并构建到一个基于物理的渗透系统模型中。该模型可用于雨水排水和收集系统的可靠设计，为澳大利亚干旱和人口稠密地区的人们带来重大利益。

Infiltration systems are widely used in sustainable management of stormwater in both urban and rural areas. They are also an integral part of large stormwater-harvesting facilities. However, they tend to fail due to clogging (infiltration medium gets filled by silt from runoff), and this phenomenon is far from being understood. The aim of this project is to develop a new prediction method of clogging of stormwater infiltration systems. Extensive 1D and 2D laboratory experimental programmes will be carried out. Models of unit processes that occur in infiltration systems will be defined/developed and built into a physically based model of an infiltration system. This model could be used for reliable design of stormwater drainage and harvesting systems, bringing major benefits to the people of drier and more populated areas of Australia.
