What is one method to determine surface drainage characteristics?

Identifying watershed and seasonal fluctuations is a key method for determining surface drainage characteristics. By analyzing the watershed, one can understand how water flows across the land, which is crucial for assessing drainage patterns. This involves looking at the topography, soil types, and land use in a given area to predict how rainfall and runoff will behave throughout different seasons. Seasonal fluctuations provide insight into periods of high water flow versus dry spells, allowing for a more comprehensive understanding of how drainage systems might function over time. Such analysis is fundamental in effective land management, infrastructure planning, and environmental protection, as it helps to anticipate potential flooding or erosion issues.

Other methods mentioned, like mapping urban developments, while useful for urban planning, do not directly inform about surface drainage. Assessing local wildlife and evaluating landscape aesthetics focuses more on ecological and visual aspects rather than hydrological patterns, thus making them less relevant for understanding surface drainage specifically.
