Current research focuses on predicting and mitigating the impacts of high hydraulic loadings on centralized wastewater treatment plants (WWTPs) under wet-weather conditions. The maximum permissible inflow to WWTPs depends not only on the settleability of activated sludge in secondary settling tanks (SSTs) but also on the hydraulic behaviour of SSTs. The present study investigates the impacts of...

The pressure changes in the liquid-filled fluid circuits of Hydraulically Interconnected Suspensions (HIS) often lead to vibration of the whole pipeline and associated structures and hence become a source of structural noise, which degrades ride comfort. This paper presents the numerical and experimental investigation into the vibration of this kind of hydraulic circuit. The one-dimensional wav...

The use of roller compacted concrete (R.C.C) without conventional cover in important hydraulic structures is investigated through laboratory observation of abrasion phenomena sujected to high velocity flow and floating particles. The main parameters affecting abrasion and erosion resistance of R.C.C. studied in the present study include: Mixed Hydraulic Mean Radius (which collectively repres...
