GIS In Water Resources C E 394KImpact of Floods to the Bridge Deterioration Process – The case of Onion Creek Oscar Galvis Nov 22 th 2016
Problem: Floods Impact Bridge “Natural” Deterioration Overtopping Impacts on Piers and abutments And a lot more!
Methodology Bridge Deterioration Due to Floods Hydrologic Information Bridge Inventory HAND Analysis Assess Impacts on Bridges Estimate Economic Impact LIDAR Information
Case Study: Onion Creek
Inputs Bridge Inventory Lidar Information (Thanks to Lukas Godbout) Height of the Bridges Hydrologic InformationNHD flowlines Maximum flowWright et al. (2012) Potential Maximum Flow for 2100
Bridge Deterioration Due to Floods Overtopping Inundation height is 90% or more of bridge structure height Treatment: Replacement Erosion of Piers Base Inundation height between 70% - 90% of bridge structure heightTreatment: Increase footing depth
Results N
Results Bridge Height = 12 ft
Results Inundation Height based on Maximum Flow = 14.2 ft
Moving Forward Automate analysis for more catchments
Thanks you for your attention!Any questions?
