Despite causing serious or even irredeemable losses, floods should be viewed as natural phenomena of landscape evolution. In the past, floods formed part of relief development and the scope of flood plains and sediments characteristics prove that floods used to be locally even more severe. Cases of recent floods inundating broader areas than in the past could be attributed to locally retained water due to unsuitably situated facilities or to extreme precipitations (in a particular local river basin). It can‘t be confirmed that activities of men were generally the main cause of floods - the statement applies only locally. To prevent damage, it is vital to study flood causes and consequences on the regional level and to tackle the problems of local enormous erosion or overflow. In areas marked by significant property damage, it is necessary to find out whether it is caused by improperly situated facilities or relatively objective causes, like extreme discharge values
