0202034 Little The mixing mechanisms induced in water by bubble-plumes will be identified and incorporated into a coupled bubble-plume reservoir model for design and operation of hypolimnetic oxygenation systems.Field testing will be conducted using a linear bubble-plume diffuser in a small water supply reservoir in Virginia and using six circular bubble-plume diffusers in a mid-sized eutrophic lake in Switzerland. Oxygen transfer and plume induced mixing will be monitored before, during and after diffuser operation. In addition, biogeochemical fluxes will be monitored.This research will enable the development of the first scientifically rigorous coupled bubble-plume/ two dimensional reservoir model that includes mechanistic features of oxygen transfer, plume-induced mixing and the impact on biogeochemical fluxes, including SOD.

0202034 小 气泡羽流在水中引起的混合机制将被确定，并纳入一个耦合的气泡羽流水库模型hypolimnetic充氧systems.Field测试的设计和操作将进行使用线性气泡羽流扩散器在弗吉尼亚州的一个小型供水水库，并使用六个圆形气泡羽流扩散器在瑞士的一个中型富营养化湖泊。 在扩散器运行之前、期间和之后，将监测氧气传输和羽流诱导的混合。 此外，还将监测地球化学通量，这项研究将有助于开发第一个科学上严格耦合的气泡-羽流/二维储层模型，该模型包括氧转移的机械特征、羽流引起的混合以及对地球化学通量的影响，包括SOD。
