What is meant by "Altered riparian boundaries"?

The term "altered riparian boundaries" refers to adjustments in land boundaries that occur as a result of shifts in the location of water bodies, such as rivers and streams. These adjustments can happen due to natural processes like sediment deposition or erosion, which can cause water bodies to change course over time. When a river alters its path, the adjacent land boundaries must also be reevaluated to accurately reflect the new positions of the neighboring waters.

This option specifically addresses the concept of land size adjustments based on the new location of the water body, indicating that ownership rights and land designations may need to change as a result. While erosion and other factors can contribute to these shifts, the fundamental aspect of altered riparian boundaries focuses on how land use and property lines adapt to the dynamic nature of waterways.
