Density-flow regime of Franklin D. Roosevelt Lake
A correlation of 2-yr data describing the thermal regime of Lake Roosevelt and comparisons with Yih's theoretical work and Debler's laboratory studies shows excellent agreement regarding the position of the interfacial layer between the upper relatively stagnant zone and the region of the primary flow transport. This agreement, however, could easily lead to conclusions regarding the entire flow regime that cannot be supported. Further study of the temperature data and confirmation by velometer shows the location of a second, lower interface that roughly conforms to the one above but showing waves of instability. It is apparent that more complex theory will have to account for the variance between dynamic and static equilibrium. The study indicates that information on refined mass transport relations is necessary for heat budget studies. The study also indicates that projects or operational concepts involving storage or release of cool water are made difficult because density currents tend to bypass cooler masses. The dynamic equilibrium prevents the formation of normal density currents and, as a result, Lake Roosevelt fills with cool water by displacement from the North without any significant horizontal distribution.
