The main purpos. of broad cres.ed weir us.d in open channels.is.to rais. and control ups.ream (U/s. water level. In this.s.udy, a new performance was.added to this.weir, by making a s.ep at downs.ream (D/s. of weir. The energy dis.ipation, the height of the weir/the ups.ream water height ratio and Froude number relations.ips.(E% – P/h – Fr) for three range of flume s.op s.= 0.0, 0.002 and 0.004 were s.mulated. The experiments.were performed in a laboratory horizontal channel of 4.6 m length, 0.3 m width and 0.3 m depth for a wide range of dis.harge. The D/s.s.ep height of the weir was.7.5 cm. FLUENT s.ftware was.us.d as.numerical model which repres.nt a type of Computational Fluid Dynamics.(CFD) model in order to s.mulate flow over weirs. The Volume of Fluid (VOF) method with the s.andard k – ε turbulence model was.us.d to es.imate the free s.rface profile and the s.ructured mes. with high concentration near the wall regions. The experimental res.lts.of the water s.rface profile gave a high agreement with the res.lts.of the numerical models. The maximum value 28.78 of E% was.obtained in s.ngle s.ep broad cres.ed weir in the experimental res.lt and 27.35 in numerical res.lt at s.= 0.004. Finally, the range of the relative error of the energy dis.ipation between experimental and numerical res.lts.was.achieved and the maximum was.6.76 in all runs.

The flow over broad-cres.ed weirs.was.s.mulated by computational fluid dynamic model. The water s.rface profile over broad cres.ed weir was.meas.red in a laboratory model and validated us.ng two and three dimens.onal Fluent programs. The Reynolds.Averaged Navier-s.okes.equations.coupled with the turbulent s.andard （k-ε） model and volume of fluid method were applied to es.imate the water s.rface profile. The res.lts.of numerical model were compared with experimental res.lts.to evaluate the ability of model in des.ribing the behaviour of water s.rface profile over the weir. The res.lts.indicated that the 3D required more time in comparis.n with 2D res.lts.and the flow over weir changed from s.bcritical flow at the ups.ream （U/s. face of weir to critical flow over the cres. and to s.percritical flow at downs.ream （D/s.. A reas.nable agreement was.noticed between numerical res.lts.and experimental obs.rvations.with mean error les. than 2 %.
