Hydrology and Hydraulic Study of an Existing Bridge on Veguitas River

Abstract

Abstract - This paper summarizes the hydraulic and hydrology studies perform to determine the capacity and replacement structure of an existing bridge. The studies will be performed at a Bridge in Veguitas River in the Municipality of Jayuya in Vegitas Ward. The bridge is affected by frequents rainfall events. For these research two models HEC- HMS, HEC- RAS developed by the US Army Corps of Engineer were used. The existing and two proposed condition were evaluated. For the proposed condition a single slab a bridge with two box culvert were modeled in order compare the behavior of the flow in the channel. Key Terms - NOAA Atlas 14, NRCS, HEC-HMS, HEC-RAS, Veguitas River
