Abstract

The accumulation of sediments in reservoirs has always been considered one of the main challenges to their sustainable use and long-term exploitation. Gate operation is utilized for sediment management, and one of the most common engineering techniques to ensure the proper functioning of the gates is pressure sediment flushing. The research aimed to improve sediment removal around gate structures by introducing a special structure. The positive results indicate the potential application of this method in various water projects like dams and canals. In this article, a new method is presented to increase the efficiency of sediment flushing around the gates. In this method, a structure consisting of two rows of parallel columns is installed at the upstream part of the bottom outlet to the tank floor. Three to six pairs of columns, with permeability of 60 %, 50 %, 42.9 %, and 37.5 % were installed in two parallel rows at relative distances of 2 and 4 from each other, and non-cohesive sand materials with an average size of 0.61 mm were deposited in the tank as sediment. The results show that the sediment flushing efficiency with the structure in the best case (permeability of 37.5 % and the relative distance between two rows equal to 2) is equal to 301.5 % compared to the case without the structure.

期刊介绍： Flow Measurement and Instrumentation is dedicated to disseminating the latest research results on all aspects of flow measurement, in both closed conduits and open channels. The design of flow measurement systems involves a wide variety of multidisciplinary activities including modelling the flow sensor, the fluid flow and the sensor/fluid interactions through the use of computation techniques; the development of advanced transducer systems and their associated signal processing and the laboratory and field assessment of the overall system under ideal and disturbed conditions. FMI is the essential forum for critical information exchange, and contributions are particularly encouraged in the following areas of interest: Modelling: the application of mathematical and computational modelling to the interaction of fluid dynamics with flowmeters, including flowmeter behaviour, improved flowmeter design and installation problems. Application of CAD/CAE techniques to flowmeter modelling are eligible. Design and development: the detailed design of the flowmeter head and/or signal processing aspects of novel flowmeters. Emphasis is given to papers identifying new sensor configurations, multisensor flow measurement systems, non-intrusive flow metering techniques and the application of microelectronic techniques in smart or intelligent systems. Calibration techniques: including descriptions of new or existing calibration facilities and techniques, calibration data from different flowmeter types, and calibration intercomparison data from different laboratories. Installation effect data: dealing with the effects of non-ideal flow conditions on flowmeters. Papers combining a theoretical understanding of flowmeter behaviour with experimental work are particularly welcome.
