FLOOD RISK AND PLANNING OF RECREATIONAL TERRITORIES IN THE AKMENA-DANĖ RIVER BASIN OF WESTERN LITHUANIA / POTVYNIŲ RIZIKA IR REKREACINIŲ TERITORIJŲ PLANAVIMAS VAKARŲ LIETUVOS AKMENOS–DANĖS UPĖS BASEINE

Abstract

Abstract Intensive summer rain showers in 2005 and 2007 caused floods in most rivers of Lithuania. A large majority of the worst problems occurred in the basins of the Akmena-Danė and Minija rivers that are adjacent to the seashore. In many cases possible dangerous consequences can be avoided by predicting and forecasting spring floods caused by heavy rain or thawing snow. As a natural disaster, a high flood occurs unexpectedly and results in a rapid rise of river level, which can cause dam failure. It is especially evident when a high water level in the Baltic Sea caused by deep cyclones results in additional surplus of river level leading to extreme gauge readings in a theoretical aspect andto flooding of territories in a practical aspect. The current research focuses on the consequences of the past, present and future possible dam failure cases in the Akmena-Danė river basin. Modeling of possible impact to other dam-protected reservoirs is also analyzed in together with some other processes, including ...
