An intimate understanding of open channel hydraulics and the interaction between acting forces of water and resisting forces of soils is essential for a robust understanding of scour, erosion, and sedimentation.  Additionally a good understanding of how land uses influence hydrology, hydraulics, and consequently channels is necessary for a robust understanding of channel morphology.  Mr. Braithwaite has developed a keen understanding of channel morphology processes through continuing education, attendance of conferences, reviewing and applying approaches described in numerous papers in peer reviewed journals, textbooks, and design guidelines.  Given this background, Mr. Braithwaite is familiar with qualitative, quantitative, empirical, and deterministic approaches to evaluate channel morphology and is not beholden to any particular approach.

Example Project

Pebble Project, Illiamna, Alaska

PHI was retained to provide guidance and senior review of channel morphology studies supporting fisheries studies being conducted for the environmental baseline document (EBD).  Duties included assisting with identification of study approach, data requirements, and analysis methods plus critical review of data, analysis, and reports as appropriate to improve the integrity and defensibility of the channel morphology component of the fisheries studies.
