Hydraulics characteristics of tipping sediment flushing gate.
This paper highlights a preliminary study on the potential of a tipping flush gate to be used in an open storm drain to remove sediment. The investigation was carried out by using a plasboard model of the tipping flush gate installed in a rectangular flume. A steady flow experiment was carried out to determine the discharge coefficients and also the outflow relationship of the tipping flush gat...
متن کاملOne dimensional simulation of flushing sediment through reservoirs
Control of sedimentation in reservoirs of dams is considered to be one of the most important issues in exploitation of dams and increasing their useful life. Reservoirs act as traps for sediments and prevent transport of sediments to the river. The deposited sediments will decrease the capacity of the reservoirs so that they cannot be in use any more. Various methods are discussed in this study...
متن کاملAlteration of macroinvertebrate community in tropical aquatic systems in relation to sediment redox potential and overlaying water quality
INTRODUCTION Fresh water is an important driving force, cycling minerals and nutrients around the terrestrial environment and has been defined as those systems comprising human communities, socioeconomic interactions, and biophysical processes co-occurring in space and time. Evaluation of the biological community of a water body provides a sensitive and cost effective means of assessing stream ...
متن کاملStream Macroinvertebrate Response to Clearcut Logging
Why study response of stream invertebrates to watershed disturbances such as clearcut logging? Stream invertebrates can be excellent integrators of changes in such ecosystem phenomena as changes in the food base of ecosystems. For example, a number of invertebrate taxa appear to track changes in food resources (Hawkins et al. 1982; Fuller et al. 1986; Wallace and Gurtz 1986; Feminella and Hawki...
