Sediment Resuspension and Transport in Water Distribution Storage Tanks

Sediment resuspension as a water quality regulator in lakes

Opportunistic pathogens relative to physicochemical factors in water storage tanks.

Household water in Oman, as well as in other countries in the region, is stored in tanks placed on house roofs that can be subjected to physicochemical factors which can promote microbial growth, including pathogens and opportunistic pathogens which pose health risks. Water samples were collected from 30 houses in a heavily populated suburb of Muscat. The tanks used were either glass reinforced...

A model of sediment resuspension and transport dynamics in southern Lake Michigan

A quasi-three-dimensional suspended sediment transport model was developed and generalized to include combined wave-current effects to study bottom sediment resuspension and transport in southern Lake Michigan. The results from a threedimensional circulation model and a wind wave model were used as input to the sediment transport model. Two effects of nonlinear wave-current interactions were co...

Sediment Issue Measuring Contaminant Resuspension Resulting from Sediment Capping

Fish facilitate wave resuspension of sediment

The resuspension of sediment by waves or currents is a major cause of turbidity in many shallow waters. Here we show that bottom-feeding fish greatly facilitate this process by reducing the erosion resistance of the sediment. We use a fish-removal experiment from a large Dutch lake to show that the absence of fish makes sediment resistant to wind effects, and we use controlled lab experiments t...
