Channel Changes And Flood Frequency On The Upper Main Stem Of The Nooksack River, Whatcom County, Washington, Roger G. Bertschi
WWU Graduate School Collection
This study focuses on three aspects of the hydrology of the lower Nooksack River that are of interest in understanding flooding processes and for planning: (1) a comparison of changes in channel locations and cross-sections at several points along the Nooksack, (2) the determination of distribution of surface sediment in exposed bars and banks, and (3) an estimation of flood frequencies by the Gumbel and Log Pearson methods. These aspects give a useful depiction of recent flooding and channel activity.
The Nooksack River channel has remained within a defined thalweg zone from 1906 to 1991, the period of map record. …
