The aim of ISMOP project

2

The use of numerical models to predict the state of the levees Visualization of test results Analysis of the measurements with the use of computer simulations Fast and secure transmission of data Massive collection of data in contunuous mode Implementation of the selected scenarious of flood wave

The idea of the project is a systematic approach to the issue of monitoring the static and dynamic behavior of the levee in real time.
