Travels Impacts of Bridge Closures 1: Lafayette Bridge Final Report
This study evaluates traffic reactions to two alternative construction plans of Lafayette Bridge crossing the Mississippi River in downtown Saint Paul, Minnesota. We calibrate a travel demand model previously developed and evaluate network performance in different construction phases of the two alternative scenarios. Most significant changes in traffic condition occur during the bridge closure ...
متن کاملInvestigation of the Impact of Bridge Structures on the River Route on the Hydraulic Behavior of the Flow (Case study: Velian River)
Introduction: As the main source of water and life for humans and other creatures, rivers may sometimes bring about destruction and irreparable damage. Therefore, it is necessary to study the hydraulic properties of the flow and the riverbed’s area to set a safe zone for human activities around it. On the other hand, constructions built along the river’s route such as bridges, weirs, superstruc...

متن کاملConstriction Scour In Pressurized Flow Condition (RESEARCH NOTE)
When depth of flow past a river bridge exceeds opening under the bridge, the flow under the bridge becomes pressurized. The water is directed downward and under the bridge deck, causing increase in velocity and shear stress on the bed thereby increasing bed scour. This is termed as Pressure Flow Scour. The present study investigates the phenomenon of pressure flow scour resulting from a submerg...
متن کاملThe effect of the geometry of the scour around bridge abutments in the river bend
Every year a large number of bridges flooding in the river just when they most need them there destroy all born. Carried out. In this study, the four fulcrum forms a semi-circular, trapezoidal, rectangular edges rounded rectangle 90 degrees at 70 degrees in Sagittarius with four different discharges depth of constant scouring around the abutment in pure water were examined. For material of flum...
