A flood protection master plan was prepared to provide recommendations and preliminary designs for managing flood risk, designing and implementing a flood warning system, and developing a watershed plan to enhance and protect water sources in Aqaba, Jordan. As part of the master planning process, hydrologic, hydraulic and sediment transport analyses were performed. The sediment transport analysis used the U.S. Army Corps of Engineers (USACE) HEC-6 model 1) to identify locations of potential general scour or deposition, and 2) estimate sediment yield for Wadi Yutum and its major tributary, Wadi Titin. The sediment transport analysis predicts the bed elevation change caused by the 100-year flow hydrograph is not significant; however, a substantial sediment yield from the Yutum/Titin watershed is predicted. Flood mitigation measures were examined, including alternatives that could reduce the sediment yield from the upper parts of the watershed. Additionally, localized scour near major bridges across the wadis is estimated to be significant.
