The thesis presents flash floods phenomenon and the differences between flash floods and
other types of floods. Flooding is usually caused by intense or long-lasting rainfall event.
These kinds of events are more often in the last years and climate changes could cause
even more natural disasters.
Flash floods are quite known phenomenon in Slovenia which is situated in many upper parts
of river basins. Flash floods and erosion are most common in northwestern hilly landscape of
Slovenia where is also measured the biggest amount of annual precipitation.
Flash floods are often accompanied by landslides, erosion, mud and debris flows. These
processes can cause even bigger damage than just flash flood only. Because of a rapid and
short-term event of flash flooding is quality forecast very important to reduce the damage.
Quality forecast depends on several different factors which all should be considered. In the
last years is popular use of remote sensing systems for more accurate flood forecasts.
The thesis also presents different types of flood protection which are used to reduce the
damage caused by flash flooding. With flood protection such as appropriate statutory
regulations for building on zones at high risk of flooding, a higher number of rain-gauges,
weather radars, satellite systems and quality structural measures we can achieve faster and
more accurate flood forecasts and measures in time.
