Modeling Lakebed Hydrogeological Properties Effects on Lake and Groundwater Interaction (Case Study: Lake Urmia), M.Sc. Thesis Sharif University of Technology ; Ataie Ashtiani, Behzad (Supervisor)
Abstract
Lake Urmia water level fell dramatically from 2006 to 2014. Since then the declining trend of water level has stopped but the lake has remained in a critical situation. Moreover, Lake Urmia became supersaturated with total salinity averaging more than 350 g/l. Salt precipitation and dissolved materials brought by inflowing rivers have formed a layer of sediment with low hydraulic conductivity on the lakebed. We conducted a series of numerical simulation scenarios to study the groundwater flow pattern in the vicinity of the hypersaline Lake Urmia using COMSOL Multiphysics®. In the first step, we performed the simulations in steady-state conditions. Secondly, we simulated the lake level fall...
