    This research project aims to look into the hydraulics of culvert structures. A culvert is a structure which controls stream flow through and underneath a roadway and embankments.The verification of the effectiveness of theoretical equations and its coefficients is vital for adequate prediction of the effect on areas surrounding a culvert structure. There are numerous theoretical culvert equations that reflect culvert hydraulics. This research report will focus on the verification of three theoretical culvert equations used in the industry, as well as a study of application of two hydraulic programs. The culvert system can function under two hydraulic controls. This study is focused on the culvert system under inlet control and covers analysis of rectangular and square portal frame culverts. The study will involve building a physical model and obtaining/gathering data for theoretical, physical, and software model comparison of culvert hydraulics. The results of the study produce a number of discharge rating curves/performance curves for the culvert system; to aid in verification process. The study will give the ability to comment on the level of performance of the theoretical equations and of the software application in comparison to the physical relationship of head water level and flow rate of culvert structures. The study also focuses on the effect of the slope of the culver system on the discharge rating curves.
