Abstract
Field measurements were conducted to investigate hydraulic environmental changes caused by destratification systems. The measurements were designed to observe the following three points: 1) spatial distribution of flow field using a ADCP equipped to a boat. 2) time series of current profile at stations near bubblers. 3) water temperature monitoring to observe thermal stratification. These observations revealed interesting behaviors of intrusion. The depth of intrusion responses to diurnal changes of surface water temperature because of the entrainment around water surface. Flow volume of intrusion was influenced by all the bubble plumes and their accompanying current.
