Allan James_Geomorphic Continuity - Lower Yuba River Accord

Introduction
• Historical fluvial changes, drawn from and illustrated
by examples of newly developed cartographic and
aerial photographic data, are examined.
• The Lower Yuba River (LYR) is a poster child for
anthropogenic pg change. It is one of the most heavily
changed rivers known, due to hydraulic mining
sediment (HMS), dredging, and engineering works.
• Knowing the history of change is essential lto
understanding river dynamics as responses to a complex
of processes and trends.
