What is a Sediment Dam (Flood Rake)?
A sediment trap is a structure built to control sediment transport in rivers and regulate water flow. These structures slow down the water speed, allowing sediment to accumulate and thereby helping stabilize riverbeds.
Manufacturing Features
- Material Use:
- Steel: Steel construction provides high strength and durability. Corrosion-resistant coatings extend the lifespan of steel structures.
- Concrete: Concrete can be used in conjunction with steel. Concrete enhances the robustness of the steel structure and provides resistance to water pressure.
- Geosynthetic Materials: Geosynthetic materials can also be used for erosion control.
- Design and Construction:
- Engineering Design: Hydraulic and structural engineering calculations determine the water flow rate, volume, and sediment carrying capacity.
- Modular Structures: Steel construction can be designed as modular structures, making assembly and disassembly easier.
- Foundation Work: Ground improvement and reinforcement work are carried out to create a solid foundation.
- Installation:
- Site Preparation: Necessary adjustments are made in the riverbed, and the structure’s foundations are excavated.
- Steel Assembly: Steel parts are assembled according to the predetermined design, using welding and bolted connections.
- Concrete Pouring: Concrete is poured in necessary areas to increase the durability of the steel construction.
Application Areas and Advantages
- Erosion Control: Sediment traps are used to prevent erosion along riverbanks.
- Sediment Management: They control sediment accumulation and maintain the depth of riverbeds.
- Flood Prevention: By regulating water flow, they reduce the risk of flooding.
- Protection of Wildlife: They protect river ecosystems and improve water quality.
Other Names and Known Applications
- Flood Dike: A term used for structures with similar purposes and structural features.
- Flood Rake: The name given to smaller-scale sediment traps, especially used in stream beds.
Example Applications
- River and Stream Rehabilitation: Sediment traps are used for erosion control and sediment management.
- Water Management in Urban Areas: Used in urban streams to reduce flood risks.
- Protection of Agricultural Lands: Sediment traps are built to protect agricultural lands from flooding.
Conclusion
Tekmetsan has added a new one to its works with the Sediment Traps application completed in Kastamonu, Turkey. Sediment Traps are essential structures for water management and environmental protection, and steel constructions enhance their durability and longevity. When proper design and manufacturing techniques are employed, these structures effectively provide erosion control, sediment management, and flood prevention. Although these structures may have various names, they all serve similar functions and contribute significantly to water management and environmental protection.
