A Framework for
Analyzing the Hydrologic Condition of Watersheds
by Bruce McCammon, John Rector, and Karl Gebhardt
The Bureau of Land Management and the Forest
Service have developed a national framework for comprehensive interdisciplinary
watershed analysis. Hydrologic condition analysis results in an
understanding of the interrelationships among meteorological, surface
and ground-water, and physical and biological factors that influence
the flow, quality, and/or timing of water. The magnitude, direction,
and rate of change are the expression of hydrologic condition. The
determination of hydrologic condition should focus on the analysis
of the factors that most directly influence changes in the specific
watershed of interest. The guidance outlines a process for identifying
the essential factors needed to describe hydrologic conditions with
the flexibility to address site-specific characteristics.
