Codes for Steady-State Bedrock Channel Width

The codes predict bedrock channel width at steady state when the bed and bank lowering rates balance the uplift rate, from measurable physical parameters, including uplift rate, water discharge, sediment supply, grain size, rock strength, and bank angle. The "codeforlocalwidthvariation" code predicts width at cross-section scales, representing at-a-station hydraulic geometry, while the "codefordownstreamvarition" code predicts width at drainage basin scales, representing downstream hydraulic geometry.本套代码基于可测量的物理参数（包括抬升速率、水流量、沉积物供给量、粒度、岩石强度以及岸坡角度），在河床与岸坡下切速率与抬升速率达到平衡的稳态条件下，预测基岩河道的宽度。其中"codeforlocalwidthvariation"代码用于预测断面尺度下的河道宽度，表征站点内水力几何形态（at-a-station hydraulic geometry）；而"codefordownstreamvarition"代码则用于预测流域尺度下的河道宽度，表征下游水力几何形态（downstream hydraulic geometry）。
