Abstract
This paper describes a set of field data suitable for the testing and comparative assessment of geomorphic flood routing methods. The data pertain to a particularly severe and unusually well-documented flood event: the Lake Ha! Ha! breakout flood of July 1996 in the Saguenay Region of Quebec. In this event, heavy rains combined with the incision of a new lake outlet caused a major flood, which significantly reworked the downstream valley. Published and unpublished data from multiple sources are assembled and co-registered in a common frame of reference. These data include vertical and oblique air photos, hydrological records, surface geology information, and digital terrain models of the pre- and post-flood valley topography. The spatial coverage encompasses the drained lake as well as the full length of the downstream valley. To meet the respective needs of two- and one-dimensional approaches, the topography is sampled on a Cartesian mesh as well as interpolated along evenly-spaced cross-sections. The data set described in the paper is provided in digital form in the electronic supplement to this special issue.
