Comparing WAAs in the same hydrogeomorphic wetland class at the same point in time. Comparing WAAs in different hydrogeomorphic wetland classes at the same point in time. The assessment procedure described in this article is being published as a WRP technical report. A variety of assessment models are being developed for use with the assessment procedure and will be published as WRP technical reports. These will be published in the form of guidebooks for each hydrogeomorphic class, and case studies of regional hydrogeomorphic subclasses.
Case studies represent the application of the hydrogeomorphic approach to a regional subclass.
Case studies scale assessment models and FCIs to the regional hydrogeomorphic subclass, using reference wetlands. Case studies are being conducted for a variety of regional hydrogeomorphic subclasses, and will provide a template for applying the hydrogeomorphic approach to additional regional subclasses.
