Bridges are crucial for transporting people and goods, but their failures can be catastrophic, resulting in loss of life property. This study assessed the flood stage selected bridges (Alaafin Avenue, Seven-Up, Oluyole) along Ona River, Ibadan, Nigeria, using a one-dimensional model called Hydraulic Engineering Center-River Analysis System (HEC-RAS). The requires two major input data: geometric...

An application is presented of a new methodology for the real-time operations river-reservoir systems. The based upon an optimization/simulation modeling approach that interfaces optimization with one and/or two-dimensional unsteady flow simulation model (U.S. Army Corps Engineers HEC-RAS). also includes short-term rainfall forecasting, and U.S. HEC-HMS rainfall-runoff modeling. Both forecasted...

The objective of this study was to assess the performance form-based and process-based models, local-scale reach-scale used examine bank retreat sediment transport in stream restoration. evaluated models were Bank Erosion Hazard Index (BEHI), Assessment for Nonpoint Source Consequences Sediment (BANCS), Stability Toe Model (BSTEM), HEC River Analysis System (HEC-RAS 1D). Model-to-model assessme...

Abstract A significant deficiency of most computer models used for stream floodplain analysis is that the locations of structures impacted by floodwaters, such as bridges, roads, and buildings, cannot be effectively compared to the floodplain location. This research presents a straightforward approach for processing output of the HEC-RAS hydraulic model, to enable two- and three dimensional f...
