美国陆军工程兵团（USACE）溶解气体减排计划（DGAS）正在研究减少与下哥伦比亚河和斯内克河水电站大坝泄漏相关的溶解气体过饱和（DGS）的方案。为了解决DGS暴露的复杂性，为USACE的瓦拉瓦拉和波特兰地区开发了气体传输、气体混合和动态气泡创伤的数值模型。这些模型耦合流体动力学，温度，DGS生产，DGS运输和鱼类分布信息与动态气泡创伤死亡率模型，这将提供一个估计的累积死亡率在鱼类种群通过哥伦比亚和蛇河大坝。
The U.S. Army Corps of Engineers (USACE) Dissolved Gas Abatement Program (DGAS) is studying options to reduce dissolved gas supersaturation (DGS) associated with spill at hydroelectric dams on the Lower Columbia and Snake rivers. In order to address the complex nature of DGS exposures numerical models of gas transport, gas mixing, and dynamic gas bubble trauma were developed for the Walla Walla and Portland Districts of the USACE. These models couple hydrodynamics, temperature, DGS production, DGS transport, and fish distribution information with a dynamic gas bubble trauma mortality model which will provide an estimation of cumulative mortality in fish populations passing Columbia and Snake River dams.
