Flow separation at water intake is the main cause of head loss and flow discharge reduction. &#10As a result, study of shape and size of separation is very essential when designing an optimum water intake. Water intake is normally built with a 90 degree angle to the main channel flow direction. However, the flow structure in this type of water intake consists of large separation size along wit...

weirs have widely been used for the flow measurement, flow diversion and its control in the open channels. attempts have been made to study flow over different shapes of normal weirs, side weirs and oblique weirs. this paper is connected with the development of the discharge coefficient measurement. in the present study four different weirs in different height are considered for validation purp...

an optimal design and fabrication of compressors requires flow investigation through the compressor components. flow field inside the volute is fully three dimensional and turbulent. better understanding of flow mechanism leads to improve the volute design procedure. in this research the experimental and numerical flow investigation through a radial flow compressor volute are performed to recog...

existence of capacity drop phenomenon, as the difference between pre-queue and queue discharge flow rates, has been one of the controversial concepts of traffic engineering. several researches have focused on capacity drop existence and also its estimation issues. this paper aims to estimate capacity drop based not only on a comparison between breakdown and queue discharge flow rates, but also ...

this study proposed a new discharge estimation method using a mean velocity formula derived from chiu’s 2d velocity formula of probabilistic entropy concept and the river bed shear stress of channel. in particular, we could calculate the mean velocity, which is hardly measurable in flooding natural rivers, in consideration of several factors reflecting basic hydraulic characteristics such as r...

Abstract Gabion weirs are environment-friendly structures widely used for irrigation and drainage network purposes. These structures' hydraulic performance is fundamentally different from solid weirs' due to their porosity the existence of a through-flow discharge. This paper investigates reliability suitability number Machine learning models estimation gabion weirs. Generally, three Boosting e...

During the summers of 1987 and 1988, 15 dye-tracer tests from a total of eight injection points were conducted in the ablation area of Midtdalsbreen, a northern outlet of Hardangerj0kulen, southern Norway. The spatial and temporal patterns of water discharge, shapes of the dye-return curves, through-flow velocities, dye-recovery rates, dispersivities, and velocity/ discharge relationships sugge...
