Generation

# Watershed Boundaries Watershed boundaries, or drainage divides, are the topographic lines that separate areas draining to different outlets, following ridges and high elevation points where water flows in opposite directions. These boundaries are determined by analyzing terrain elevation data using the **steepest descent principle**, where water flows perpendicular to elevation contours toward lower elevations. The key formula for determining flow direction is: **Slope = ΔElevation / ΔDistance** or **S = (z₂ - z₁) / L** Watershed area (A) can be calculated using GIS tools or planimetry, and is essential for hydrologic calculations like the Rational Method: **Q = CiA** (where Q = peak discharge, C = runoff coefficient, i = rainfall intensity, A = drainage area).
