Abstract

Weirs are common structure to regulate water surface and flow control in water conveyance channel and HYDRAULIC STRUCTURE. One of effective and economical method to increase the efficiency of weirs is utilization of LABYRINTH WEIRs which length of weirs increase with modification of plan form and therefore flow discharge will be increase. In this research, the discharge coefficient and the unit length discharge of LABYRINTH WEIR with linersemi circular and semi circular with radius of 11, 16 and 20 cm and cycle of 2 to 6 was experimentally investigated. Comparison of results showed that in all labyrinth FLOW DISCHARGE COEFFICIENT had increasing trend with increase of relative effective head ( HT / P ) then decrease for HT /P>0.37 due to collision of nape and with increasing HT / P , weir coefficient tend to broad crest weir because of local submergence. Comparison of results showed that the LABYRINTH WEIRs with circular plan have a better performance in comparison with liner-circular plans.
