River Training Work for Meandering Rivers
Introduction
River training work is the process of modifying natural rivers to prevent erosion and sedimentation by designing and constructing structures or modifying the river's course. The river training work is generally required when the river is meandering. In this article, we will discuss why river training work is required for meandering rivers.
Meandering Rivers
Meandering rivers are the ones that have a winding course. These rivers have a slow velocity, and their channel is wider than the straight rivers. The meandering rivers have a tendency to erode the outer banks and deposit the sediment on the inner banks, which results in a change in the course of the river. As a result, meandering rivers are more prone to flooding and can cause damage to the surrounding areas.
Why River Training Work is Required for Meandering Rivers
The following are the reasons why river training work is required for meandering rivers:
1. To Control Erosion
Meandering rivers have a tendency to erode the outer banks, which results in the widening of the channel. River training work is required to control erosion by constructing structures such as revetments, gabions, and groynes to stabilize the banks.
2. To Control Sedimentation
Meandering rivers tend to deposit sediment on the inner banks, which causes the channel to become shallower. River training work is required to control sedimentation by dredging the riverbed and constructing structures such as weirs and barrages to regulate the flow of water.
3. To Prevent Flooding
Meandering rivers are more prone to flooding as they have a slow velocity and a wider channel. River training work is required to prevent flooding by constructing structures such as levees, floodwalls, and floodgates to control the flow of water.
Conclusion
In conclusion, river training work is required for meandering rivers to control erosion, sedimentation, and flooding. The construction of structures such as revetments, gabions, groynes, weirs, barrages, levees, floodwalls, and floodgates can help in stabilizing the river and prevent damage to the surrounding areas.
