Final answer:
To correct erosion around a check dam, assess the area, reinforce with materials like rocks or sandbags, and monitor the structure. Preventative measures and consideration of the structural integrity are critical.
Step-by-step explanation:
The procedure for correcting erosion around the sides of a check dam includes assessing the area for any structural weaknesses or damages that have allowed erosion to occur. After identifying the problematic areas, one should reinforce the dam with additional materials such as rocks, boulders, vegetation, or geotextiles to protect the bank and prevent further erosion. It may also involve the strategic placement of sandbags to address active leaks, similar to how they are used to manage water flow around river levees as described in some of the provided figures. The repair process should aim to stabilize the structure and restore the integrity of the check dam while taking into consideration the hydraulic forces exerted by the water it retains. Additionally, regular monitoring should be implemented to ensure the longevity of the repairs and the overall health of the dam infrastructure.
Case Study Consideration
In relation to the Vajont Dam example, it's critical to assess the geological stability of the area around the dam to prevent catastrophic failures. Proactive measures should be taken before and throughout the life cycle of a dam to address any signs of instability within the structure or its immediate environment.
