Abstract
The floods occurring in Europe recently confirm that some natural phenomena
are unexpected and very difficult to control. Despite this, the proper subjects of
infrastructure and scientific institutes try to find common decisions to minimize
flood risk levels as much as possible. Currently the European Commission is
reviewing legal documents and in the near future EU countries will have to
implement flood management directives.
This paper presents a developed mathematical model of flood control which
was applied for Kaunas hydropower system. The model consists of two parts:
water level calculation algorithms, which were developed using only operational
system data, and a risk based water level control model based on an optimization
algorithm and integrated risk parameters. The model helps to accept risk based
decisions during the flood period and offers alternatives of discharge and water
level control near the dam. As a result the flood control characteristics and
extreme scenarios are presented.
Keywords: risk based decision making, flood management, optimization model.
1 Introduction
Floods in recent years have brought huge economical losses and put a significant
number of human lives in big danger. In 2006, the European Commission will
review and negotiate six legislation acts and one of them is a flood management
directive. On 18/01/2006 the European Commission proposed a directive on the
assessment and management of floods [1]. Its aim is to reduce and manage the
risks that floods pose to human health, the environment, infrastructure and
property. Two trends point to an increased flood risk and to greater economic
damage from floods in Europe. Firstly, the scale and frequency of floods are
likely to increase in the future as a result of climate change, inappropriate river
