从博恩霍尔姆盆地通过Stolpe海峡的高盐水团的地下流动对波罗的海中央盆地深层沃茨的更新起着重要的作用。为了确定是否旋转112层水力理论是一个合适的工具来描述这一过程，最大运输估计的气候数据的基础上，从博恩霍尔姆和格但斯克盆地已经建立。这些被发现大大偏离观测的现实，因此类似的水力考虑也适用于或多或少的天气场数据从芬兰的现场活动进行了通过在20世纪80年代中期。此外，在这种情况下，显着差异之间的计算运输能力和观察。由于它furthermorewas证明，所观察到的跨渠道水文结构的特点，可以解释使用的深水流量的摩擦平衡模型，它已得出结论，水力框架，虽然提供了一个上限的运输，是有限的使用时，处理斯托尔佩渠道溢出。虽然不能排除流入是无粘性的，但次最大，它更有可能是由摩擦和风强迫的综合影响的运输。
ABSTRACT The subsurface flowof high-salinewater masses from the Bornholm Basin through the Stolpe Channel plays an important role for the renewal of the Baltic Central Basin deep waters. In order to determine whether rotating 112 -layer hydraulic theory is an appropriate tool for describing this process, maximal-transport estimates based on climatological data from the Bornholm and Gdansk Basins have been established. These were found to deviate considerably from observational realities, and hence similar hydraulic considerations were also applied to more-or-less synoptic field data from a Finnish field campaign carried through in the mid-1980s. Also in this case significant differences were found between calculated transport capacity and observations. Since it furthermorewas demonstrated that the characteristics of the observed crosschannel hydrographic structure could be explained using a frictional-balance model of the deep-water flow, it has been concluded that a hydraulic framework, although providing an upper bound of the transport, is of limited use when dealing with the Stolpe-Channel overflow. Although it cannot be excluded that the inflow is inviscid, but submaximal, it is more likely that the transport is governed by the combined effects of friction and wind forcing.
