Title

EFFECTS OF GROINS AND DROPS ON FLOOD DEPTH AND EXTENSION (CASE STUDY: TEHRAN KAN RIVER)

Pages

  109-119

Abstract

 In contrary to different benefits that a river may have for urban, industrial and agricultural sectors existed on neighboring areas, it may be supposed as a serious threat to the vicinity areas as well as structures constructed on it. The construction of unsuitable and ill-designed structures such as bridges, flood walls, GROINs and dikes may have significant effects on flood occurrence and exaggeration. The effects may be imposed through changing the cross sections, flow velocity, storage area, flow level and surface area. In the present study, the effects of GROINs and DROPs on inundation depth and extension have been investigated in a 7 Km reach of KAN RIVER, TEHRAN. The hydraulic analyses were made for floods with 5 to 700 years return periods using HEC-RAS computer software package in two situations of structures presence and absence. The results of the study revealed that the trend of changes occurred in flood depth and the type of hydraulic structures and channel geometric conditions affects area as well. The results also showed that the DROPs were more effective on flood main characteristics than GROINs. The non-significant effects of GROINs on flood area and significant role of DROPs on inundation depth was found to be as another finding of the present research.
