Flash-flood Risk Assessment Map and Forecaster / Warning System

Keywords: geoinformatics, hydrology, soil science, GIS, flashflood, risk assessment, forecast, digital map

Occurrence and general characteristics of flash floods formed in the mountainous regions of Hungary are profoundly influenced by the changing climatic conditions of the region. Other factors like topography, soil, vegetation, are also important controls of runoff.

Rationalization of the spatial structure of supplier system using roads

Keywords: geoinformatics, transport organization, rationalization, software

This know-how is based on the GRASS GIS system for determining the time spacing between point-linked objects connected to a road network. The solution is suitable for determining how long it is possible to reach selected points (real locations) from one point to another so that the quality, capacity and speed of the road network can be freely parameterized. Each point can be assigned any amount of specific data that allows the meaning of the points to be freely modified, including their initial, intermediate, and endpoints.

Simulation of river processes and tectonic movements

Keywords: geoinformatics, geomorphology, hydrology, geological modelling, digitalizing

The computer-controlled sandtable is developed by the researchers of the Faculty of Sciences of the University of Pécs. It is used to reproduce hydrologic, tectonic and geomorphologic processes. The sand table is equipped with multiple electric engines which enable tilting along its longitudinal and transversal axes and compartments for vertical movements and 4 push-blades for lateral movement. Digital picture information is collected by 8 digital overhead cameras, 3 infrared and 2 time-lapse cameras.
