The Modeling and Organizational Structure behind the Columbia River Treaty
I
n January, Pete Dickerson covered the modeling and political aspects behind the Columbia River Treaty.
Pete went into the technical background behind a recent Army Corps of Engineers (USACE) flood modeling software called the Hydrologic Engineering Center Watershed Analysis Tool (HEC-WAT). HEC-WAT couples hydrology and hydraulics into one cohesive model. The watershed for this model spans the vicinity of the Columbia River, encompassing seven U.S. states and Canada. This new model was performed by in-house USACE staff.
Pete also shared some of the politics and the structure of the legislation and organizational chart.
See Pete if you are interested in more information about this project. While much of it is classified, some aspects are available to the public and engineering and scientific professionals.
