摘　　要：由于阻力和渠道沿途配水引起流速变化,渠内水面高程沿程变化,引起配水不均。通常我们采用调整闸板高程改变闸孔面积的形式提高配水均度。基于水力学基本原理推导一种近似的水面曲线计算公式,为合理快速调整闸板高程提供依据。It can produce distributing asymmetry that water surface fluctuate with change of resistance and velocity of flow in channel. A practical way to solve this Problem is to adjust the high level of Floodgate board, based on hydraulic principle ,this text deduce formulas to calculate values of water surface level in distributing channel so that it is easy to adjust highness of Floodgate board,
