Title

COMPARATIVE EVALUATION OF BRIDGES AND CULVERTS EFFECTS ON FLOOD DEPTH AND EXTENSION IN A REACH OF TEHRAN KAN RIVER

Pages

  64-67

Abstract

 Improper design and unsuitable application of BRIDGEs and CULVERTs may affect on flood occurrences through changing the river cross section, flow velocity, flood storage capacity, flow level and extension. In the present study the role of three BRIDGEs as well as three CULVERTs constructed in a reach of Tehran KAN RIVER with 7Km in length was studied for floods with 5 to 700 years return periods. The effects of studied structures on inundation depth and extension were studied for both the fictitious omission as well as present condition with the help of HEC-RAS software package. The results of the study revealed that each particular structure plays specific hydraulic role on floods having different return periods which is different from others. The results also verified that the CULVERTs have more effects on changing inundation depth and extension compare to BRIDGEs.
