Abstract

Background and Objectives: Rivers run in a sinus curve pattern usually and have a direct pathway rarely. Joining LATERAL CHANNEL to main channel at a bend location changes completely the conventional FLOW PATTERN at river bend. Recent FLOW PATTERN not only is affected by centrifugal force and stream and spin wise pressure gradient but also by momentum of LATERAL CHANNEL flow. Exact recognizing of this phenomenon needs extended studies.Materials and Methods: In this study using SSIIM1 model the effect of three position of straight LATERAL CHANNEL that is connected to a U BEND at 45, 90 and 135 degree from the start of bend with a 90 degree confluence angle on flow velocity, variation of water surface elevation, shear stress distribution and helical flow strength was considered.Results: The results indicated by increasing the JUNCTION POSITION from 45 to 135 degree from the bend start, stream wise flow velocity near the outer wall of the bend increases maximum %56 while near the inner wall of the bend decreases %8.Conclusion: Maximum difference between the upstream and downstream flow depth around confluence area at 45 degree position was equal to %6.15 of tail water depth. For position of 135 degree from the bend start this difference was about %5.4 of tail water depth. Additionally the results indicated shear stress at confluence area increases %8 when the position of junction angle change from 45 to 135 from start of bend.
