两个半云湖的盐度分层已被详细记录。我们提供了七年来关于在德国中部矿区 Merseburg-Ost 褐煤矿坑中形成的 Wallendorfer See 和 Rassnitzer See 的半混积湖盐度分层的现场数据。主要来自地下水流入，在两年的时间里有意引入淡水以更快地填充坑以接近最终水位之前，已经形成了盐度分层的半叠残湖。根据观察，盐度分层的变化可以用沉积势能来解释。淡水引入（封顶）以势能的形式进行量化。因此，盐度剖面的演变得到了解释，并且由于洪水过程，它们的残余形状也变得可以理解。根据对冬季深层再循环期间层结中沉积的能量的定量估计，可以对莫莫林尼亚的进一步演化做出前瞻性陈述。
Salinity stratification has been documented in two meromictic lakes in detail. We present seven years of field data on the salinity stratification of meromictic lakes Wallendorfer See and Rassnitzer See forming in the pits of the former lignite mine Merseburg-Ost in the Central German Mining District. Mainly from groundwater inflows, salinity stratified meromictic residual lakes had formed before freshwater was introduced intentionally over a period of two years to fill the pits more rapidly close to the final water level. From the observations, changes in the salinity stratification were interpreted in terms of deposited potential energy. Freshwater introduction (capping) was quantified in terms of potential energy. Thus the evolution of the salinity profiles was explained and their residual shapes became understandable as a consequence of the flooding procedure. Based on the quantitative estimates of energy deposited in the stratification during deep recirculation in winter, prospective statements could be made about the further evolution of the monimolimnia.
