MIKE 11 is a computer program that simulates flow and water level, water quality and sediment transport in rivers, flood plains, irrigation canals, reservoirs and other inland water bodies. MIKE 11 is a 1-dimensional river model. It was developed by DHI.
MIKE 11 has long been known as a software tool with advanced interface facilities. 
 Since the beginning MIKE 11 was operated through an efficient interactive menu system with systematic layouts and sequencing of menus. It is within that framework where the latest ‘Classic’ version of MIKE 11 – version 3.20 was developed. 
The new generation of MIKE 11 combines the features and experiences from the mike11
MIKE 11 ‘Classic’ period, with the powerful Windows based user interface including graphical editing facilities and improved computational speed gained by the full utilization of 32-bit technology.
