 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 Water • Environment • Health.

MIKE11 has long been known as a software tool with advanced interface facilities. Since the beginning MIKE11 was operated through an efficient interactive menu system with systematic layouts and sequencing of menus. It is within than framework where the latest ‘Classic’ version of MIKE 11 – version 3.20 was developed.

The new generation of MIKE11 combines the features and experiences from the 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.

Modules

The computational core of MIKE 11 is hydrodynamic simulation engine,and this is complemented by a wide range of additional modules and extensions covering almost all conceivable aspects of river modeling.
