1 Introduction
Basic information
Dam break flood modelling training using MIKE 11 modelling software package
was organised in July 2013, in Bobrovník, Slovakia. The training was part of EUfunded Programme for the Prevention, Preparedness and Response to Man-made
and Natural Disasters in the ENPI East Region (PPRD East). The training was
conducted by The Academy by DHI, represented by DHI Slovakia. Official training
language was Russian.
Participants
Together 12 participants were trained from Armenia, Azerbaijan, Belarus, Georgia,
Moldova, Ukraine, 2 participants from each country.
2 Training
2.1 Training overview
The training was carried out in following basic steps:

Introduction to 1D hydrodynamic modelling using MIKE 11 modelling
software tool

Basic practical example – river Hron

Presentation of participating countries on dams selected for dam-break
analysis, overview and evaluation of available data

Hands-on-job training: modelling of dam-break by individual country teams,
using relevant pilot river, dam and reservoir data

Presentations of dam-break analyses results by individual country teams

Week 1 Training overview
WEEK 2
Day 1 – Day 5: hands-on-job
Practical modelling of selected river reach and simulation of dam break situation
Study locality was selected by teams from participating countries.
Data were prepared in advance by client on the basis of guidance from DHI. Those teams whose
data were not sufficient for the whole dam break analysis were provided by set of data from river
Hornád, prepared by DHI.
Practical training work flow followed steps explained and exercised in week 1. Part of the second
week of training was excursion to dam Liptovská Mara. Technical concept of the dam and hydro
power plant were described by Slovak Water Management Enterprise staff. System of early
warning in case of crisis situations was presented as well.
Training was completed by presentations of teams from individual participating countries,
demonstrating achieved hydrodynamic modelling of dam break, results of numerical simulations
and dam break analyses.
The participants obtained official certificates of The Academy by DHI.

3 Summary and recommendations
Dam break flood modelling training using MIKE 11 modelling software package
was organised by The Academy by DHI. Together 12 participants from 6
individual countries successfully completed the training.
It is recommended that the participants will continue in further development of
their knowledge and expertise by practical hydrodynamic modelling or relevant
activities utilising results of hydrodynamic simulations, depending on their working
position.
