Water Quality and Sedimentation in Urban Tidal River

Abstract

Behavior of later Quality and Sediment in Estuary region is influenced by Floods and Tide, There is a complicated phenomenon. Estuary region is catchment area for run-off of rain fall, living waste water, and Basic flow of urban small riers is extremely small quantity.
There fore, precipitation and sedimentaion is easily in estuary region. Pollution load is on the increase in fooding.
This paper is result of investigation to use numerical analysis of a dementional unsteady flow equation and diffusion equation and datas of observation about behaviors of water pollution and bottom deposits at tidal reach in urban small river.
The following was clarified by this research about at area of sediment in quantitative with relation to tractive force
