stream bank stability assessments and possible erosion mitigation measures will be evaluated, even along those . used with gabion walls, sand-cement bag revetments and other precast retaining wall systems. Typically, the Bulkheads can be constructed out of sheet pile, sheet metal or timber and are most useful at the

Locate the bridge foundation on bedrock when possible, or below the depth of scour, and use stream bank protec- tion measures such as riprap. include simple log sills, gabions, masonry retaining walls, or con- crete stem walls with footings. Some simple bridge foundation details are shown in Figure 10.2.
gabion walls. A crib wall, concrete or timber, is a gravity retaining structure that consists of interlocking concrete or timber elements. Each crib unit is filled with BMP Objectives. Perimeter Control. Slope Protection. Borrow and Stockpiles. Drainage Areas. Sediment Trapping. Stream Protection. Temporary Stabilizing.
When vegetation is not an option, a rock facing is recommended. Galvanized welded-wire units function as the construction form and also provide the long-term facing stability. Welded Wire rock faced retaining wall systems work when your site requires a retaining wall for grade separation. Welded wire basket forms are
Tosomeen designed this structure as a retaining wall. Steel anchors bolt the log wall into the vertical em- bankment and provide security to the wall until the vegetation is established. In addition, the most criti- cal point at the bottom of the live crib wall is secured with a solid riprap toe. To remedy the stream's four- foot drop in
Description. A log retaining wall and rock cascade built across the bed of the creek to control an retaining wall. The rocks forming the cascade should be at a slope of 1 vertical to 8 horizontal and should finish flush with the top of the log retaining wall. Lay rocks to encourage the stream to flow towards the centre of the
Diverse fields of stream restoration, mine reclamation and stormwater 8) Utilize log cribbing and rip rap as additional barrier to tailings Stabilizing tailing retaining wall with stream restoration trechniques. WSW added a vane arm and bank stabilization from stream restoration techniques to protect the retaining wall.
The most common civil engineering use of gabions was refined and patented by Gaetano Maccaferri in the late 19th century in Sacerno, Emilia Romagna and used to stabilize shorelines, stream banks or slopes against erosion. Other uses include retaining walls, noise barriers, temporary flood walls, silt filtration from runoff,
Where are you? Where I am from (Dallas TX) railroad tie walls rot and shift. And due to the wood treatment chemicals in the ties there are environmental regulations which limit disposing of rotted ties. I would not bring railroad ties onto my property, especially near a stream. In Dallas "gabion walls"
Adjacent to highways, streams, runways, and other structures and land developments, segmental and mechanically stabilized earth retaining wall systems are solving many grade-separation, slope stability, and erosion control problems. Retaining wall manufacturers provided the following project summaries demonstrating
Stream channel erosion problems vary widely in type and scale and there are many different structural stabilization techniques which have been employed with varying degrees of effectiveness. The purpose of this specification is merely to point out some of the practices which are available and to establish some broad

STEP 3 Cover the bottom and the sloping sides of the stream bed with inch of crushed pea gravel. .. We may need to do something like this, but using logs we find on the.
Big precast concrete blocks provide big advantages. By Fernando Pagés Ruiz. Bob Hampton builds neighborhoods with rolling hills, trees, meandering streams and small ponds. Sculpting these bucolic subdivisions requires extensive use of retaining walls, shore liners and detention cells. Faced with a
The Stream Killers. Dams and Log Jams; Channeling and Wetland Drainage; Eroded Soil and Silt; Fertilizers and Animal Wastes; Pesticides; Waste Oil; Coal Mine Sediments and .. Straight walls (breakwalls, wavewalls, retaining walls) are expensive to construct and maintain; they are unsightly and generally short-lived.
Log jamming. This is a fairly new technique that is slowly gaining popularity among stream restorers. It works in much the same way as riprapping, only that in this case, log jams are used. The logs are carefully positioned along the bank to act as a buffer zone and to prevent soil from eroding. Stormwater management.
Gabion Retaining Wall. Practice 513 Moderately eroded stream banks may be repaired with minimum regrading, and the installation of live stakes, a Sheet piling may be preferred in areas where aesthetics are not important, and where space limitations prohibits the construction of a timber or concrete wall. All structural
PROTECTION EROSION REPAIR. Traditional methods of controlling erosion have relied on “hard” structural practices such as covering banks with interlocking concrete blocks and building retaining walls. However, these techniques often have negative impacts on streams. In many. BANK PROTECTION EROSION REPAIR
