Comparison of the quality of thalweg lines extracted from data of DMR 4G, DMR 5G and its derivatives

ABSTRACT Determining the gradient of watercourses in the case of local applications is a common problem, which is most often dealt with by geodetic surveying. However, determining the gradient of all watercourses in the Czech Republic is a challenge. The use of geodetic methods on such a scale is usually unrealistic. Therefore, it is necessary to choose a different approach, such as the extraction of the gradient lines from other already existing elevation data. The DMR 4G and DMR 5G are elevation models currently… Read more »

Development of the RainWaterManager software tool

Rainwater management is currently one of the frequently discussed topics in the further territorial development of towns and municipalities. The same question is also addressed in the context of climate change and its effect on already existing urban areas. Currently, the most common solution for the disposal of rainwater is its drainage using sewage systems. In connection with climate change, this concept of rainwater management is beginning to show its disadvantages. Rainwater is quickly drained away, which negatively affects moisture conditions in the urban landscape. The consequence of this is its drying and overheating. Another disadvantage is overloading of sewer networks during extreme rainfall events. The solution to eliminate these disadvantages can be an effort to retain the precipitation at the point of impact. However, this concept brings with it a number of questions: What measures can be used for this purpose? What are the spatial requirements for creating these measures? What is the price of their implementation? Can local government demand implementation of these measures by private investors? the answers to these questions are often not trivial and depend on the specific circumstances and the number of assessed criteria. Some help in this regard comes from the RainWaterManager software. This tool helps to choose appropriate measures for rainwater management, to estimate its effectiveness, spatial and economic requirements, and shows how their implementation can be promoted.

Identification of non-point agricultural pollution using thermographic imaging

Water quality monitoring has a much shorter history in the Czech Republic (CR) than water quantity monitoring. Yet the quality of water resources is crucial for society, industry and agriculture.

Bathymetric measurement for determination of morphology of water reservoir bottom

Information and communication technologies are currently one of the decisive factors influencing economic and social development. Similar developments and trends in relation to information and communication technologies can be observed in the field of water management.
