An application of data mining for the determination of flooded areas was published in the Journal Geodetski vestnik (no. 54/2010-4). This paper analyses the usefulness of these results for further ...analyses of hydraulic parameters. The velocity and discharges were computed for six locations. The study showed that the flooded areas determined by satellite images can be used for further analyses. Nevertheless, other layers have to be sufficiently precise, especially the digital terrain model (DTM). DTM 12.5 was used. The study showed that DTM 12.5 is not precise enough. The observed area is very rough and the hydraulic parameters (cross sectional area of flow, wetted perimeter, hydraulic radius, river-bottom slope, flow velocity, discharge) cannot be detected with sufficient precision. Consequently, the calculated hydraulic radiuses, velocities and discharges are out of expectations. In the first part of the article, some basic information about remote sensing and its techniques is presented. Some practical examples of their usage (especially satellite images) for the observation of natural disasters are also given.
This book (‘(Irresponsible responsibility’) features thirteen chapters written by nearly thirty specialists in natural disasters. The chapters deal with various topics ranging from earthquakes, ...landslides, avalanches, and floods (with an emphasis on the extensive floods in September 2010) to protected forests, drought, and education about natural disasters.

Slovenia is endangered by floods. Frequent intensive rainfall and heavy rains, a large proportion of mountainous and hilly regions, and numerous populated narrow valley bottoms are the primary ...reasons for this threat. Floods endanger about seventy thousand hectares of lowlands, and torrential flooding endangers a further three thousand hectares. Due to this enormous threat, Slovenia has more than one hundred years of experience in the field of flood prevention, while only more recently has the awareness developed in the European Union that flood prevention is cheaper in the long run than simply dealing with the consequences of floods. This fact is reflected in the increasing number of laws passed to deal with this danger, and for this purpose maps of flood hazard and flood risk are very important and are presented in the book.
