Abstract

Numerical modelling of ice growth and transport of matter in lakes, estuaries, or coastal seas can provide crucial input for improving the environment. In this paper, the goal is to model the thermal stratification and ice dynamics in Lake Teletskoye, which is located in the Altai republic of Russia. Lake Teletskoye is a deep lake with a maximum depth of 325 m. The Delft3D modelling suite is applied for simulation of the temperature stratification and the ice formation in Lake Teletskoye, which is the first Delft3D application of ice melt and growth in a deep lake. Modelling deep lakes requires a special approach for the computation of the density. In Delft3D the UNESCO equation is applied, which is less suitable for deep lakes. Therefore, Delft3D has been extended with the TEOS-10 and the Chen-Millero density formulas, which yield accurate model results for Lake Teletskoye.

热分层和冰动力学建模及其在俄罗斯阿尔泰共和国的捷列茨科耶湖的应用

摘要

湖泊，河口或沿海海洋中冰的生长和物质运输的数值模型可以为改善环境提供重要的投入。在本文中，目标是对位于俄罗斯阿尔泰共和国的捷列茨科耶湖的热分层和冰动力学进行建模。特列茨科耶湖是一个深湖，最大深度为325 m。Delft3D建模套件用于模拟Teletskoye湖中的温度分层和结冰，这是第一个Delft3D应用在深湖中融化和生长冰。对深湖进行建模需要一种特殊的密度计算方法。在Delft3D中，使用的是联合国教科文组织方程式，该方程式不适用于深湖。因此，Delft3D已使用TEOS-10和Chen-Millero密度公式进行了扩展，
