Project Description
Project Title: Floodplain Analysis and Conceptual Levee Alignment along the Gila River
Locaton: Duncan, Arizona
Description: NAU Crown Engineering performed a floodplain analysis of a 3.5 mile reach of the Gila River in Duncan, Arizona. The project’s objective is to provide insight on Duncan’s current risk of flooding based on updated topography and revised 100 year flow conditions. In addition, a levee alignment was proposed and analysed to see its impact on the floodplain. All analyses was performed with HEC-RAS and Civil 3D software and can be expressed through three essential models:
1- Effective Model- Replication model of original floodplain evaluation that was performed in the area. In the case of Duncan, The Federal Emergency Management Agency (FEMA), produced a series of floodplain studies that began in 1974 and were completed in 2007. Ultimately, the production of the effective model is to ensure that the initial floodplain study was correct and reproducible. The goal is to move beyond this model and create a modern version that is more reflective of new hydraulic/topographical conditions.
2- Corrected Effective Model- Using recent (2012) Lidar data of the area, an improved model of the study reach was developed. This model reflects how the Gila River currently behaves as opposed to the outdated effective model.
3- Proposed Conditions Model- Based on information provided from the Corrected Effective Model, a new hydraulic model was developed with the addition of a levee alignment. The goal of this model is to show the impact within the floodplain by assuming a levee placement with a specified height.

Bio: Phoenix, Arizona is where I was born and raised. I wanted a break from the hot temperatures of the Phoenix area, so I chose to earn my degree in civil engineering at Northern Arizona University. Since then, I have fallen in love with the cool temperatures and beautiful scenery of the Flagstaff area. Upon graduating, I would like to work in the fields of either transportation, water resources, or structural engineering. I like all of these fields in civil engineering and can’t wait to see what my future holds!

Name: Abdulaziz Ebrahim
Bio: I was born and raised in Kuwait. After I finished high school, I got a scholarship from the Kuwaiti Government to earn a bachelor's degree in Environmental Engineering in the United States. I moved to the United States in October of 2010 and spent my first year here studying English at the University of Central Florida in Orlando. I then moved to Northern Arizona University in 2012 to begin my undergraduate studies. My dream is to become a professional engineer.
