Experimental data observed from culvert hydraulic model to investigate the influence of various headwall/wingwall combinations

This dataset contains the observed experimental results from a model study to investigate the hydraulic improvements, under inlet control, that can be obtained by installing a headwall/wingwall combination inlets. The experimental model was undertaken at the University of Pretoria Waterlab.
The dataset contains the measured flow (m3/s) vs the measured upstream head (m) for three different inlets, namely a 90 degree inlet, a 45 degree inlet and a 30 degree inlet. The dataset forms underpinned a dissertation on improvements to the hydraulic performance of culverts under inlet control conditions through the optimisation of inlet characteristics.

本数据集汇集了针对在入口控制条件下，通过安装挡墙/翼墙组合入口所能获得的液压改进的模型研究观测实验结果。该实验模型在南非比勒陀利亚大学水工实验室进行。数据集内包含了针对三种不同入口（即90度入口、45度入口和30度入口）所测得的流量（立方米每秒）与上游水头（米）的对应关系。该数据集为通过优化入口特性来改善涵洞在入口控制条件下的水力性能的论文提供了理论支撑。
