HOW MISAPPLICATION OF THE HYDROLOGIC UNIT FRAMEWORK DIMINISHES THE MEANING OF WATERSHEDS

Water resources in the future: problems and solutions. The present water crisis has many components of an environmental, economic and social origin: overuses of water, pollution, changes in availability, and water mismanagement are some of the current problems. To cope with these problems and enhance strategies for long term management, the following programs and approaches are presented: a A watershed approach, integrating research, monitoring, data base and management; b An improved water governance system based on participation of stakeholders and the public and private sector; c Strategic studies considering water and the economy, water and metropolitan regions, water and energy; d A framework for international cooperation on shared watersheds; e An economic evaluation of water resources services surface and underground, lakes, rivers and reservoirs. Introduction: the main causes of the water "crisis". According to some specialists, the water crisis in the 21st century is much more related to management than to a real crisis of scarcity and stress Rogers et al. Nevertheless, according to other specialists, it is the result of a set of environmental problems aggravated by economic and social development problems Gleick, According to these authors, a consolidated data base transformed into a management tool can be one of the most effective forms of confronting the problem of water scarcity, water stress and deteriorating quality.

Definitions, strengths, and limitations of watersheds

Hydrologic units provide a convenient but problematic nationwide set of geographic polygons based on subjectively determined subdivisions of land surface areas at several hierarchical levels. The problem is that it is impossible to map watersheds, basins, or catchments of relatively equal size and cover the whole country. The hydrologic unit framework is in fact composed mostly of watersheds and pieces of watersheds. The pieces include units that drain to segments of streams, remnant areas, noncontributing areas, and coastal or frontal units that can include multiple watersheds draining to an ocean or large lake. Nonetheless, hydrologic units and watersheds are commonly treated as synonymous, and this misapplication and misunderstanding can have some serious scientific and management consequences. We discuss some of the strengths and limitations of watersheds and hydrologic units as spatial frameworks. Using examples from the Northwest and Southeast United States, we explain how the misapplication of the hydrologic unit framework has altered the meaning of watersheds and can impair understanding associations between spatial geographic characteristics and surface water conditions.
