Modeling Projects MaxDepth staff have conducted lake, stream , and watershed modeling in support of FERC relicensing, TMDL analyses, and watershed restoration efforts. Model applications include SWAT analyses (with Dr. Kellie Vache) of the Tenmile Lake watershed (manuscript in review) and the Sprague River watershed. New aspects of the model calibration have included use of paleolimnology to provide hindcasts for altered watersheds. MaxDepth staff will also be applying QUAL2k to the Sprague River using recently compiled data sets regarding stream water quality collected by the Klamath Tribe, combined with detailed information on macrophyte and periphyton biomass and distribution. MaxDepth staff have applied the 2-d hydrodynamic model (CE-QUAL-W2) to Lemolo Lake to assess the complex mixing patterns created by two inlets of greatly different temperatures and three outlets from the impoundment. The results showed the sensitivity of the system to the geometry of the channel at the major inlet from the North Umpqua River in mixing with the warmer water from Lake Creek (the outlet from Diamond Lake). One of the most challenging applications of CE-QUAL-W2 we encountered was the calibration of the model to Odell Lake. Odell Lake is a elongate, deep (86 m) lake with a strong prevailing west-to-east wind that causes Odell Lake to experience internal seiches with an amplitude up to 25 m. The model successfully reproduced the observed conditions, which will allow us to compute the degree of internal cycling of nutrients in the metalimnion (AVI of model run). |
