Anchoring Debris Boom in a Calm River
How Do I Anchor a Debris Boom in a Calm River?
Question: I would like to find out from you what the procedure is in actually fitting the unit across a calm river with a width of 40 meters? What other equipment do I need to affix the boom on either side of the river bank? Does one need to have some sort of positioning stabilizer in the center of the total length to avoid extreme curving?
Answer: Thank you for asking. There are couple of different ways you could consider positioning your debris boom in a calm river. Depending on exactly how calm your river is and/or available equipment, different methods may work better than others (see all debris booms).
The two typical anchoring techniques used for this type of deployment include the following:
- Anchoring Directly to the Shore: This is done through piles. Ends of the booms can be tied to these pilings to keep them securely anchored while at work.
- Anchoring to the Water Bottom: This is achieved by putting rope above the debris boom and securing it with concrete bucket anchors placed on the water bottom.
Debris Boom Installation and Anchoring
How you anchor and how many anchor points are needed depends upon the water conditions, current, waves, in your area. Plans for anchoring are usually developed through conversation or exchange of information regarding the currents, waves, tides, and other conditions. Some typical anchoring procedures include the use of anchors, buoys, and ties (shown left).
Anchors are connected to buoys, which are then connected to the barrier. These anchors can be placed along the barrier at various points to help your containment boom stay in place. For a barrier or debris boom in calm river water, this is usually not necessary unless there is some kind of current.
