Flood flows in inundated urban environment constitute a natural hazard. During the 1213 January 2011 flood of the Brisbane River, detailed water elevation, velocity and suspended sediment data were recorded in an inundated street at the peak of the flood. The field observations highlighted a number of unusual flow interactions with the urban surroundings. These included some slow fluctuations i...

A three-dimensional water quality model was developed for simulating temporal and spatial variations of phytoplankton, nutrients, and dissolved oxygen in freshwater bodies. Effects of suspended and bed sediment on the water quality processes were simulated. A formula was generated from field measurements to calculate the light attenuation coefficient by considering the effects of suspended sedi...

abstract settling basins are essential hydraulic structures which have to be designed and constructed at all river water intakes to remove most of suspended sediments which enters the intake by flowing water. there have been many techniques for designing these structures. to simplifying the design procedure, some of these techniques have been applied many assumption and some others are so compl...

abstract nowadays, measuring water quality is very important for comprehensive management of water resources. suspended sediment is one of the most important water quality factors which greatly affects environment health. however, its measurement needs too much time and money. it was therefore tried in the present study to assess the applicability of modelling relationship between suspended sed...
