2020年10月，威尼斯泻湖在其千年历史上首次暂时关闭。 Mo.S.E. 的第一次行动该系统是一套人工屏障，旨在在涨潮时将泻湖与大海隔离，防止威尼斯和其他泻湖定居点发生洪水。除了其历史价值之外，从水动力的角度来看，泻湖入口的关闭还导致了前所未有的情况。与 Mo.S.E.系统运行后，泻湖内将无法再记录显着的高潮，并且只能通过水动力模型来估计未受干扰的潮汐传播。当入口关闭并且潮汐传播的影响消失时，风对跨泻湖设置的作用增强并且变得更清晰可辨，从而允许对低到中等风速的风阻系数进行稳健校准。此外，Mo.S.E. 第一次关闭期间收集的数据。闸门允许评估通过关闭的闸门进入泻湖的真实闸门内渗透情况，并表明闸门操作也会产生一些向海扰动。
In October 2020, for the first time in its thousand-year-old history, the Venice Lagoon has been temporarily closed. The first operations of the Mo.S.E. system, a set of artificial barriers built to isolate the lagoon from the sea in case of high tides, prevented Venice and the other lagoonal settlements from flooding. Beyond its historical value, the closure of the lagoon inlets has led to unprecedented scenarios from a hydrodynamic standpoint. With the Mo.S.E. system operational, significant high tides can no longer be recorded within the lagoon and the undisturbed tide propagation can only be estimated through hydrodynamic modelling. When the inlets are closed and the effect of tide propagation nullified, the action of wind on cross-lagoon setup is enhanced and becomes more clearly recognizable, allowing for a robust calibration of the wind drag coefficient also for low to moderate wind speed. Furthermore, the data collected during the first closures of the Mo.S.E. gates allowed evaluating the real intra-gate infiltration entering the lagoon through the closed gates, and suggested that the gate operation produces some seaward disturbance as well.
