在冬季，从Leschenault河口的潮汐外流形成一个浮力剪切分层羽在Koombana湾的每一个出局潮。在密集的现场计划收集的测量的基础上，在羽流中的湍流和当地卷吸到羽流检查。水平分离的传感器之间的相干测量用于检查湍流的各向异性。粘性和浮力对湍流的影响进行了研究，使用的活动图，这也是混合效率和总混合的指标。Osspeak-Cox模型进行了测试，发现是有效的羽。
In winter, tidal outflow from the Leschenault Estuary forms a buoyant sheared stratified plume in Koombana Bay on each outgoing tide. The turbulence in the plume and the local entrainment into the plume are examined based on measurements collected in an intensive field program. Coherency measurements between horizontally separated sensors are used to examine the anisotropy of the turbulence. The effects of viscosity and buoyancy on the turbulence are studied using an activity diagram which is also an indicator of the mixing efficiency and total mixing. The Osborne-Cox model is tested and found to be valid in the plume.
