2 Hydrology 2
3 Basic Hydrology Low flows most common Flows that fill the stream to the banks and higher are much less common Filling the stream to the natural banks is approximately a 2 year flood 3
4 Culvert Hydraulics 4
5 Hydraulic Performance Overtopping Design Full 5
6 Fluvial Geomorphology The bankfull flow determines stream geometry Bankfull depth Bankfull width Meandering 6
7 7
8 Typical Meandering River Mississippi River Drainage Area 1,127,000 mi 2 Scale 1 in = 4 miles Tillatoba Creek Drainage Area 80 mi 2 Scale 1 in = 400 feet 8
9 Channel Forming Discharge Incipient motion 9
10 Bankfull Indicators Floodplain at the elevation of incipient flooding Highest elevation of depositional features in the active channel Break in bank slope and/or change in particle gradation (fine material is overflow and not bedload) Inundation features (benches) Rock staining, root hairs, lichens 10
11 Bankfull Channel Forming Discharge 11

13 Geomorphic Classification Variables d bkf bankfull depth w bkf bankfull width w 2bkf w bkf d bkf d bkf w 2bkf width at twice bankfull depth 13
14 A Laboratory Study of the Meandering of Alluvial Rivers. By J. F. Friedkin, Captain, Corps of Engineers 1 May If you can, let your river be a river!! Let it breathe and have some freedom! 14

17 17
18 P = sinuosity 18
19 Geomorphic Characteristics Width to depth ratio = w bkf / d bkf Sinuosity = S stream / S valley Entrenchment ratio = w 2bkf / w bkf 19
20 HOW STREAMS NATURALLY DISSIPATE ENERGY Longitudinal Profile 20
21 21
22 Past Stream Fixes 22
23 Illinois Indiana Planform Geometry 23
24 24
25 Stream Crossings have the Potential to Impair Stream Systems Focusing flows (too narrow a culvert) Increasing velocity (smooth surfaces) Overdesigned (too wide to transport sediment) Improper slope 25
26 Evidence of Stream Impairments Bank erosion Hanging culvert Scour pool Deposition Head cut 26
27 27
28 28
29 What to Remember: desirable geomorphic forms for high quality habitat Width to depth ratio < 40 Sinuosity > 1.2 Entrenchment ratio >
30 Common Stream Crossing Non Geomorphic Designs Overwidened Section Narrow Section Improper slope 30
31 Overwidened Stream Crossing 31
32 Geomorphic and Hydraulic Feedback of Overwidening Bridge section is wider than natural cross section Depth of channel forming flow under bridge is shallower than in natural channel Sediment competence and capacity under bridge is reduced Deposition 32
33 33
34 34
35 Geomorphic and Hydraulic Feedback of Slope Change Change to flatter slope results in slower velocity (Manning) Slower velocity results in larger depth (Manning) % decrease in slope greater than % increase in depth (Manning) Sediment competence and capacity under bridge is reduced Deposition 35
36 Deposition at bridge 36
37 Narrow Stream Crossing 37
38 Geomorphic and Hydraulic Feedback of Narrowing Hydraulic constriction backs up water upstream Larger depth upstream means slower velocities reducing competence and capacity (Manning) Slower velocities result in overtopping and/or deposition In crossing (pipe/bridge), higher velocities than natural (continuity, Manning) Water leaving pipe extremely aggressive resulting in scour downstream 38
39 Upstream deposition 39
40 Velocity distributions in a natural channel Higher velocity results in higher shear 40
41 Downstream erosion 41
42 42
43 43
44 Bridge Constriction Effects High Capacity Low Capacity Bank Instability 44
45 Attendant Issues Loss of floodplain to right of way Loss of riparian buffer Loss of substrate Stormwater runoff Disconnecting stream networks 45
46 Desirable Stream Crossing Geomorphically and ecologically transparent 46
47 Aquatic Organism Passage AOP 47
48 Changes in Fish Habitat Due to Disconnectedness 48
49 Potential AOP Barriers at Culverts Velocity Depth Jump Turbulence Length Lack of light Debris accumulation 49
50 Seasonal Movement 50
51 Culvert Assessment Protocols 51
52 52
53 End 53
54 Implementation Can Occur, but Most Likely Will Require Additional Structures Direct flow and sediment into the stream crossing Dissipate the flow downstream of the stream crossing Preserve low flow hydraulics 54
55 Example of stream crossing with structures to assist geomorphic continuum Twin 5 ft RCP 55
56 56
57 W-Weir 57
58 58
59 Direction of Guidelines 59
60 State of Washington Stream Simulation width = 1.2 W bkf + 2 ft culvert slope < 1.25 stream slope 60
61 Commonwealth of Massachusetts Habitat embed/open bottom 25% culvert diameter embedment openness ratio=area/length < 0.25 width = 1.2 W bkf similar low flow depth and velocity 61
62 Problems with these concepts limited geomorphic focus Crossing width > 1.2 W bkf primarily low flow habitat consideration 62
63 What to Remember: desirable geomorphic forms Width to depth ratio < 40 Sinuosity > 1.2 Entrenchment ratio >
64 Effect of These Criteria Utilize the geomorphic dimensions of the poorest habitat stream types (F, G) for the most valuable habitat stream types (C, E) Do not consider flood flows or floodplain drainage 64
