How do you identify backswamp areas on a map?

Backswamp areas can be identified on a map by looking for low-lying regions adjacent to rivers or streams, often depicted as floodplains. These areas typically have contour lines that are closer together, indicating a gentle slope, and may also be marked by symbols representing wetlands or water bodies. Additionally, topographic maps may show elevation changes that highlight depressions where water can accumulate. Environmental maps may also indicate these areas with specific shading or color coding.
