The work was performed as part of a study to evaluate water regulation alternatives that could minimize negative impacts and increase ecological benefits of dam operation. We used a one-dimensional model (HEC-2) to estimate the ordinary high-water profile and water surfaces at various discharges and management options, by river mile. Maps of these data were then created with a geographic information system, along with maps of land elevations, both above and below the surface of the river, lands controlled by the managing agency, and levees. The ownership and easement, ordinary [...]
