The sea-ice module in Delft3D, which is a flexible integrated modelling suite for hydrothermodynamics, morphology (waves, water quality) and interactions between these processes. Numerical results A special version of Delft3D On the basis of the field data in a GIS project "Teletskoye Lake" the digital elevation model (DEM) of the lake basin was built (Marusin K.V.) To simulate the physical and chemical processes in Teletskoye Lake, data on the morphometric characteristics of its basin are required A number of 1DV-models for physical and chemical processes in deep stratified reservoirs have been developed in IWEP SB RAS (Zinoviev A.T.).
In the 90’s Teletskoye Lake was considered as one of the reservoirs analog of the designed Katun reservoir in the environmental assessment study of the Katun hydroelectric power plants project. The Teletskoye Lake ecosystem is complex and has been studied in many major national and international research programs. For the development of methods for mathematical modeling of deep stratified reservoirs, we experimentally and theoretically studied the thermal and gas regimes in Teletskoye Lake - a unique natural reservoir in the south of Western Siberia. This requires the implementation of the correct setting of simulation (specified description of effective turbulent exchange, the formation of density stratification (thermocline and thermal bar), density flows, seiche fluctuations, etc. One of direction of solving the problem is to develop mathematical models of hydrological and physico-chemical processes for assessing and predicting the state of ecosystems in large lakes and reservoirs. In terms of climate change and increasing human pressure on water bodies and their watersheds urgent task is to improve water and environmental monitoring of the environment.
