A Simulation Study of Fishway
The paper argues that modelling provides a convenient and cost eeective means of characterizing and predicting the behaviour of environmental systems disturbed by man. A series of modelling criteria are suggested that aim at compelling modelling to work with current data, explicitly represent the current understanding of a system, include considerations of variability and address predictive unc...

15 صفحه اولNumerical simulation of flow in a fishway of Karkheh-Hamidieh diversion dam and environmental considerations to investigate possibility of fishway use in Mazandaran Province
Pool and weir is a type of fishway that provides a route for fish to migrate to damupstream. The effective parameters for fish swimming include velocity, water depth andturbulence. Several rubber dams have been under construction in Mazandaran Province, butthe necessary structures have not been built around them yet. When constructing these rubberdams, numerical models can be used to evaluate f...
متن کاملAn Efficiency Analysis of a Nature-Like Fishway for Freshwater Fish Ascending a Large Korean River
Using traps and passive integrated transponder (PIT) telemetry, we investigated the effectiveness of the nature-like fishway installed at Sangju Weir on the Nakdong River, Korea. In 11 regular checks over the study period, 1474 individuals classified into 19 species belonging to 5 families were collected by the traps, representing 66% of the species inhabiting the main channel of the Nakdong Ri...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
