Which mapping activity identifies land uses and drainage patterns?

• A. Watershed Mapping
• B. Stormwater Flow Tracing
• C. Visual Assessment Method
• D. Nutrient Monitoring

Answer: (A)

Mapping land uses and drainage patterns within a watershed helps you see how the landscape influences runoff, pollution sources, and how water moves across the land. Watershed mapping involves outlining the watershed boundary, identifying the drainage network (streams, rivers, channels), and documenting what the land is used for (urban areas, agriculture, forest, wetlands) across different parts of the area. This combination directly shows where different land uses are located and how water drains through those areas, which is exactly what’s being asked. Stormwater flow tracing focuses on following how water moves through specific channels after rainfall, which is more about flow paths than the broader pattern of land use and drainage networks. The Visual Assessment Method is about visually judging water quality indicators in the field, not creating a map of land uses and drainage features. Nutrient Monitoring measures nutrient levels in water, not the spatial layout of land uses or drainage systems.
