英文摘要: Abstract(#br)The stream power law, expressed as E = KA m S n — where E is erosion rate [LT1 ], K is an erodibility coefficient [T1 L (12 m ) ], A is drainage area [L 2 ], S is channel gradient [L/L], and m and n are constants — is the most widely used model for bedrock channel incision. Despite its simplicity and limitations, the model has proved useful for topographic evolution, knickpoint migration, palaeotopography reconstruction, and the determination of rock uplift patterns and rates. However, the unknown parameters K , m , and n are often fixed arbitrarily or are based on assumptions about...
