The Study of Effect of Dredging and Dike Construction on the Flow Hydraulic and Reduction of Flood in Downstream of the River (Case Study: Karun River Downstream Between Ahvaz and Farsyat) Original Article, C27 Monjezi R, Heidarnejad M, Asadi Lor M, Hoseini E. Journal. Civil Eng. Urban. 3(4):170-175. 2013 ABSTRACT:The aim of this study is to simulate a numerical model for flood spreading and to control it in Karoun River in the downstream of Ahvaz to Farsyat which is affected by dredging and the construction of dike. Using the HEC-RAS 4.1 software, one-dimensional flow model in this field was simulated. After entering the data to the model and calibration, the model was run based on selected design flow rates, and water levels were calculated and areas of flood spreading were defined. Then, the mathematical model was run based on the dredging and dike construction. Due to lack of efficiency of dredging operations for flood control and the lack of a suitable location for deflecting flow, the only practical and cost-effective method for controlling the flood of the Karoun River in the studied interval is to construct a dike with designed height.

Ancient Tunnel and Diversion Channel in Seleuceia Pieria: A Flood Diversion System near Antiochia in Turkey Original Article, C1 Alkan A,ÖZİŞ Ü. Journal. Civil Eng. Urban. 3(1): 01-05. 2013 ABSTRACT:The diversion system at Çevlik, near Antakya in Turkey, had the purpose to prevent the siltation of the antique harbour of Seleuceia Pieria. This 875 m long system consists of a dam, a short approach channel, the first tunnel, a short intermediary channel, the second tunnel, a long discharge channel. The construction began in 1.century A.D. during the reign of Vespasianus, continued under his son Titus and several successors, completed in 2.century A.D. during the reign of another roman emperor, Antonius Pius. The tunnels of simple horseshoe and trapezoidal cross-sections, with dimensions in the order of 5 to 7 m, have a capacity of 150 m3/s. The capacity of the open channel section is computed as 70 m3/s, corresponding to a peak flood discharge with average recurrence interval of about 10 years.
