The proposed research will focus on theoretical and applied problems in inland and coastal waters, both natural (lakes, rivers, estuaries, fjords) and man-made (water filled mine pits, mine tailings ponds, reservoirs). Almost all water bodies are density-stratified, due to variations in temperature and/or the concentration of dissolved and suspended substances. This stratification inhibits the vertical movement of heat, salt, oxygen, nutrients and pollutants, and is thus of considerable environmental and economic importance. The applicants’ research is primarily directed to understanding processes that overcome density stratification and facilitate vertical mixing. The two main research areas are:

拟议的研究将侧重于内陆和沿海水域的理论和应用问题，包括自然水域（湖泊、河流、河口、峡湾）和人工水域（充水矿井、矿山尾矿库、水库）。由于温度和/或溶解和悬浮物浓度的变化，几乎所有的水体都是密度分层的。这种分层抑制了热、盐、氧、营养物质和污染物的垂直运动，因此具有相当大的环境和经济重要性。申请人的研究主要是为了理解克服密度分层和促进垂直混合的过程。两个主要的研究领域是：
