The main goal of the TRANSCAT project is to create an operational and integrated comprehensive Decision Support System (DSS) for optimal water management of catchments in borderland regions. The analysis of system requirements was followed by the analysis of possible architecture of the complex system and its appropriate design. The core of the proposed(More)
The main goal of our system is to provide the end user with information about an approaching disaster. The concept is to ensure information access to adequate data for all potential users, including citizens, local mayors, governments, and specialists, within one system. It is obvious that there is a knowledge gap between the lay user and specialist.(More)
Floods are the most frequent natural disasters affecting the Moravian-Silesian region. Therefore a system that could predict flood extents and help in the operative disaster management was requested. The FLOREON system was created to fulfil these requests. This article describes utilization of HPC (high performance computing) in running multiple(More)
Geoinformation technology, particularly GIS and digital terrain models, is commonly used at present in order to derive parameters of basins and flow paths. These parameters are subsequently used to create spatially based rainfall-runoff models. In line with the development of geoinformation technologies such models can be derived both in 2D and 3D formats.(More)

Soil is one of the most important natural sources on earth. The same way as all parts of the environment, and the global ecosystem generally, it suffers from several kinds of human activities in the landscape. One of the most serious environmental problems of our present days is accelerated soil erosion and related processes. In the past, the most of soil(More)

Soil erosion is one of the main environmental problems of this time. Erosion in its recent accelerated form is the reflection of the human activities in the landscape. Soil erosion is a complicated process. Its behaviour and final rate are results of an interaction of whole group of factors. One of these factors is the character of land cover whose main(More)
Natural disasters have occurred for a very long time, virtually on all continents, and it is obvious that in the areas where human’s social, economic and cultural activities are concentrated, their impacts are more severe. The Laboratory for Modelling and Simulations of Hazardous Situations, operating at the VSB-Technical University of Ostrava, works on a(More)
GIS are used for the rainfall-runoff model development and determining its parameters. GIS data comprise soil layer, topography including three dimensional data, and land cover data. Rainfall estimations from remote sensing radar measurements and historical records of rainfall measurement are applied together with hydrometeorological ground station(More)
