Abstract:

Physical and mathematical models were used to investigate the hydrodynamics of stratified flow within B. Everett Jordan Lake, to predict the temperature and dissolved oxygen D.O. regimes of the lake immediately upstream of the dam, and to estimate the temperature and D.O. content of the release. The hydrodynamic phenomena in the lake were significantly influenced by lake geometry, two highway crossings in the New Hope arm of the lake, and the relatively large quantity of flow contributed by the Haw River. The two highway crossings essentially divide the New Hope arm of the lake into three pools. The lower pool is influenced primarily by the Haw River, and the upper pool is influenced only by the New Hope River. The results of the numerical simulations indicate that the multilevel outlet works can be operated such that downstream temperature and D.O. objectives can be satisfied.
