　NILIM 2.0 is an update model of NILIM 1.0, which calculates flood behavior caused by undrainage with Sewage Pipe Network Model and Floodplain Mesh Model (2-D).
　We enable it so that it could interactions between water inside and outside of levees using the Channel Model, Levee Breaking Model and etcetera.

Considering drainage into and overflow from Sewages 　It is able to deal with levee breaking, riverine overflow and overflow from sewage system. It is also able to seal with combinations of them. more information	Reproduce water flow inside and overflow from sewage 　As to water flow inside sewages, it can deal with both open water flow and pressure flow, enabling you to reproduce a sequence of water behavior, which overflow from sewage onto the ground. more information
Modeling various structures on floodplain 　You can place various kinds of structures on the Floodplain model. more information	Various kinds of figures facilitate you to see analysis results 　It shows kinds of information such as flood conditions, water levels inside sewages and water levels of rivers, in comprehensible figures more information
