1 Flood Fighting and Surveillance Don Moses Civil Engineer February 2016 US Army Corps of Engineers 1
2 Agenda Levee Design Common Failure Modes Surveillance/Inspection Flood Fighting 2
3 Levee Design Issues Slope Stability Thru Seepage Underseepage Critical Exit Gradient Berm Weight Overtopping Resistance Streambank Erosion Protection 3
4 Levee Components Riverside Natural Blanket Riverside Riprap Protection Riverside Impervious Face and Cutoff Random Fill Core Landside Seepage Control Berm Topsoil and Vegetative Cover Landside Toe Drain and Relief Wells 4
5 Underseepage Control Relief Wells 5
6 Failure Modes Overtopping Through Seepage/Piping Underseepage/Piping Slope Failure Riverside Erosion 6
7 Overtopping at Access Ramp (June 17, 2011) Low spots created by traffic Common to all levees Low spots created by levee foundation settlement Sand levee can not resist overtopping Clay levees are more resistant to overtopping but will eventually fail with sustained overtopping 7
8 L550 North of Hwy 136 8
9 Contributing Factors for Through Seepage Lack of Clay Riverside Face on a Sand Levee Animal Holes Undocumented non engineered levee penetrations Culvert Separations Culvert Pervious Bedding Exposed to River 9
10 Through Seepage/Piping Water Side Levee Land Side Water exiting on levee slope Burrows Animal Burrows - Beavers and Badgers Rodent Hole Rodent Caught in the Act 10
11 Failure Mode Through Seepage/Piping Drainage structures and other changes or transition areas (e.g., levee to floodwall) are potential weak points 11
12 Failure Mode Through Seepage/Piping 12
13 Contributing Factors for Under Seepage Geological cross section Remnant River Meanders Lack of Riverside Natural Impervious Blanket Damaged blanket from erosion or manmade excavation Animal holes Encroachments non engineered levee penetrations Encroachments landside ditch excavations Encroachments landside quarry excavations Inefficient relief wells and toe drains Historic levee loading Riverside erosion 13
14 Underseepage/Piping Water Flow Pipe Development (Movement of Material) Sand Boils with movement of material 14
15 Highway 2 (June 17, 2011) 15
16 Highway 2 16
17 Highway 2 3 Mile Setback 17
18 Highway 2 Sand Boils 18
19 Erosion & Landside Sandboils at Riverside Ramps 19
20 Same Location - After Water Receded 20
21 L575 Riverside swirl - indicates seepage through levee 21
22 L575 - Landside of Riverside swirl Water exiting after seeping through levee 22
23 L575 - Levee collapses on itself Cause by seepage through the levee
24 Failure Mode Slope Failure Water Water Riverside Slope Failure *Most Common Landside Slope Failure Note stakes and flagging 24
25 Failure Mode Slope Failure 25
26 Areas of Potential Erosion Riverside levees Riverside ramps Riverside fences Historic Borrow Pits Levee Alignment Floodplain Geometry Trees 26

35 Surveillance Activities Know failure modes and indications of distress EARLY IDENTIFICATION OF DISTRESS IS CRITICAL TO EMERGENCY RESPONSE (Repairs or Evacuations) 35
36 Walk the Levee Crest and Riverside Toe Riverside Issues Levee freeboard read staff gages Erosion High Water Velocities / Turbulent Flows Crest Issues Overtopping Cracking / Slides 36
37 Walk the Levee Crest and Landside Toe Landside Sideslope Thru Seepage / Piping Rodent Holes Crack / Slides Landside Toe and Adjacent Area Sand boils / Piping Slides Relief Wells and Toes Drains 37
38 Documentation Document conditions in the field Flagging, stakes, paint Photos, videos, daily reports & checklists Proper handoff to next inspection team and upward reporting Ask for assistance 38
39 Staff Gages Is the water level going up or down? Gage 1 - Just Downstream of Highway 1 Bridge Date Time Reading 1-Apr 8: Water Level 1-Apr 12: Apr 16: Apr 20: Apr 0: Increasing 2-Apr 4: Apr 8: Apr 12: Apr 16: Apr 20: is at a gage reading of 85.7 Top of water at this location Decreasing 39
