Abstract

Abstract Assessment of Manning’s unevenness factor is of critical significance in hydraulic readings of open channel stream. Manning’s ( n n ) is obligatory for the computation of releases, water levels, and backwater curves, as well as plan curve additions. The correct value of Manning’s roughness coefficient ( n n ), i. H. a value that accurately reflects the observed data, is selected by the calibration process. The current study aims to calculate the Manning coefficient of the Dujila Canal due to this factor helps in developing water management systems, the Dujila Canal (a branch of the Tigris River) was modeled using the Hydrologic Engineering Center River Analysis System steady-flow model to guess the rate of Manning’s factor. The information was reserved for seven cross sections for calibration, then another cross section is applied for the verification process. A statistical test on the recorded data must be used to verify the calibration process. It uses the Root Mean Square (RMS) test. The outcomes show that the appropriate Manning’s ( n n ) rate was (0.025), providing a reasonable arrangement amid the designed and perceived sketches

瓦特/伊拉克杜吉拉运河曼宁系数的评估

曼宁不均匀因子的评估在明渠水力学读数中具有重要意义。曼宁（n n）是计算泄流、水位、回水曲线以及平面曲线附加值的必备项。曼宁粗糙度系数（n n）的正确值，即准确反映观测数据的值，由校准过程选择。目前的研究旨在计算杜吉拉运河的曼宁系数，因为该因素有助于开发水管理系统，使用水文工程中心河流分析系统的稳定流量模型对杜吉拉渠（底格里斯河的一条支流）进行建模，以猜测曼宁系数的比率。该信息保留给七个横截面用于校准，然后将另一个横截面应用于验证过程。必须使用对记录数据的统计测试来验证校准过程。它使用均方根（RMS）测试。结果表明，适当的曼宁（n n）率为（0.025），在设计和感知的草图中提供了合理的安排
