Tokyo Institute of Technology – WAter Reservoir Model (TITech-WARM)
TITech-WARM is a three-dimensional unsteady hydraulic model. After TITech-WARM was proposed as a numerical hydraulic model to solve a three-dimensional water flow in a river channel, TITech-WARM has been improved and applied to various types of water flow; saltwater intrusion into a river channel, transport of dissolved oxygen and assessment of hypoxia, wind-driven current and generation of thermal stratification in a lake, sediment transport in a water reservoir and so on.
