Abstract

OVERFLOW IS ONE OF THE MOST COMMON HYDRAULIC STRUCTURES THAT WITH DIFFERENT OBJECTIVES IN WATER TRANSFER SYSTEM TO BE USED. THIS TYPE OF OVERFLOW WIDELY TO DIVERT THE FLOW AND CONTROL THE WATER LEVEL IN IRRIGATION AND DRAINAGE, FLOOD DIVERSION OF RIVER ENGINEERING PROJECTS AND URBAN DRAINAGE SYSTEMS USED. DUE TO THE EXTENSIVE USE OF SIDE OVERFLOW, THIS TYPE OF OVERFLOW SHOULD BE CHARACTERIZED SO THAT IT IS SUITABLE FOR WATER AND WASTEWATER TRANSPORT NETWORKS AS WELL AS DIVERSION OF RIVER SYSTEMS USED. SOME OF THESE CHARACTERISTICS CAN BE USED TO ACCURATELY MEASURE THE FLOW RATE OF WATER THROUGH THE APPROPRIATE CHANNEL AND ITS ABILITY TO LEAVE A SIGNIFICANT AMOUNT OF FLOW IN PLACES SUCH AS PROTECTIVE STRUCTURES USED, AMONG OTHERS. UNFORTUNATELY, COMMON SIDE WEIRS (SIMPLIFIED) NOT HAVING THE ABILITY TO SIMULTANEOUSLY SO THAT IF THE SPILL IS SMALL, ONLY SUITABLE FOR MEASURING THE FLOW AND IF THE OVERFLOW, BE CONSIDERED GREAT, JUST TO DRAIN FLOOD APPROPRIATE AND ACCURATELY MEASURE THE FLOW RATE IS REDUCED. THAT'S WHY FOR THE FIRST TIME, OVERFLOW EDGE IS PROPOSED. ACCORDING TO INVESTIGATIONS CARRIED OUT IN THE CONTEXT OF SUCH SPILLOVERS NO STUDY HAS BEEN DONE AND ONLY A FEW EXPERIMENTAL STUDIES ON THE NORMAL COMPOUND WEIR EDGE (WHERE THE CHANNEL WIDTH AND PERPENDICULAR TO THE DIRECTION OF FLOW ARE CONSTRUCTED) ARE PERFORMED. COMPLEX MODELS, A SIMPLE HYDRAULIC STRUCTURES THAT ARE GENERALLY COMBINED CROWN SHAPE OF A TRIANGULAR OPENINGS (AT THE BOTTOM) AND A RECTANGULAR OPENING (ON TOP) AND COMPOSITE SCORE OF HYDRAULIC WEIR FLOW MEASUREMENT OVER A WIDE RANGE FROM LOW TO HIGH WITH HIGH SENSITIVITY AND PRECISION NEEDED IN IRRIGATION CANALS OR LABORATORY FLUME. IN THIS STUDY, THE HYDRAULIC CONDUCTIVITY IN THIS TYPE OF OVERFLOW FLOW AND OVERFLOW BEHAVIOR AT DIFFERENT RATES AND DIFFERENT ASPECTS WILL BE DISCUSSED. RESULTS PRESENTED IN THIS STUDY, THE DESIGN OF THE CONTROLLER AND IS USED TO MEASURE THE FLOW. IN THIS PAPER, A SERIES OF EXPERIMENTS TO INVESTIGATE THE EFFECT OF LENGTH AND HEIGHT OF THE BOTTOM EDGE OF THE OVERFLOW WEIR DISCHARGE COEFFICIENT WAS DONE IN INK ON THE EDGE. THE GOAL OF THIS RESEARCH PROGRAM COMBINED OVERFLOW FLOW-3D MODELING AND SIMULATION AND MODELING TO OTHER WORDS SUCH AS NUMERICAL OVERFLOW AND TO OBTAIN RESULTS THAT ARE DIFFERENT IN TERMS OF SIZE AND HYDRAULIC.
