Topographic data play an important role in the hydrodynamic modelling of flood events. An accurate and precise digital elevation model (DEM) with a bathymetric description of the river channel is often required. DEMs can be derived from various data sources, e.g. ground surveying or remote sensing techniques.
Informatics, cartography in water management
The database of water resources protection zones (OPVZ) was established at the T. G. Masaryk Water Research Institute, p.r.i., approximately in 2004. In the following years, a number of partial updates took place.
Possibilities of using old topographic maps from the years 1763–1768 for evaluating the development of water bodies and the potential for their renewal
Potential of water areas restoration is a hot topic in present landscape planning. The focus is usually on water areas from mid-19th century where their location is quite good due to maps’ positional accuracy. Yet, we can also use older Austrian military survey from 1763–1768, which enables us to locate dams of water areas and assess potential for restoration of these areas.
Water towers – research project mapping the development and a form of tower water reservoirs on our territory
The paper presents a summary of input information about the research project Water towers – identification, documentation, presentation, new use. It deals with the development of tower water reservoirs in the present territory of the Czech Republic from the beginning of their creation to the present.
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.
This article aims to present to the general public the results of the assessment of the ecological status/potential and chemical status of surface water bodies categories “river“ and “lake“ for the period 2013 to 2015 in the Czech Republic. The assessment was carried out in 2017 by the Water Research Institute of T. G. Masaryk, p. r. i.
Airborne laser imaging (LiDAR) has been carried out throughout the Czech Republic, enabling the creation of raster of digital model of terrain. This material is widely used in various fields. From the point of view of hydrology demands, however, the shortcoming of this technology resides in the absence of accurate/complete channel topography due to the absorption of the near-infrared laser beams by water.
The article presents the results of a Project TD020113. This project was focused on the estimation of future water withdrawals in the Czech Republic between 2030 and 2050. We analysed four possible social-economic pathways of the Czech society.
River Basin Management Plans data processing enables obtain not only detailed summary of results, but also appreciates relations between partial results and their significance to achievement of specified objectives.
Process of implementation of Directive 2007/60/EC on the assessment and management of flood risks in conditions of the Czech Republic
The purpose of the Directive 2007/60/EC on the Assessment and Management of Flood Risks (Flood Directive) is to prevent or reduce negative consequences of floods by preparing flood risk management plans.
Surface water body typology category river in the 1st and 2nd cycle of River Basin Management Plans and its consequence to ecological status assessment
Surface water body delineation and setting a typology are one of the initial steps during Water Framework Directive implementation (WFD) . The first delineation and typology was prepared in 2004–2005 for the first plans, but all the results were significantly changed in the second cycle 2009–2010.
Reporting of River Basin Management Plans under Water Framework Directive in 2016 in the Czech Republic
In 2015 the River Basin Management Plans (RBMP’s) for the 2nd planning cycle under Water Framework Directive were designed and approved. According to the Directive the copies of the RBMP’s were sent to the Commission by 22. 3. 2016.
Water planning is a systematic conceptual activity which implements the requirements of the Water Framework Directive.
Ponds are an important and organic part of the landscape in the Czech Republic through ages. They are spread over most of the area of the republic and have different functions besides the one which is historically the most important – fish farming.
The article deals with the development of agriculture bare soil surface using the stereophotogrammetric method. It describes and compares the development of selected soil characteristics investigated on four types of field cultivation.
One part of the project “Strategy for protection against negative impacts of floods and erosion phenomena by naturefriendly measures in the Czech Republic“ was assessment of actual runoff conditions in the Czech Republic by runoff curve number method.
Article introduces presentation portal “Voda v krajině“ (www.vodavkrajine.cz) as an information source about natural water retention measures.
In this article results of analysis of future water withdrawals from water resources for public water supply systems are summarized.
Summary Flood risk of levee protected areas stems from the possibility of levee failure due to overtopping, breaching or uncontrolled seepage. In most cases, levee breaching leads to highest damages as such events occur suddenly and can hardly be forecasted. In this article, levee failure is referred to levee breaching only. Whenever levees break during… Read more »
The National Spatial Data Infrastructure and the Reflection on the expected Role of Cartography and GIS Products provided by the T. G. Masaryk Water Research Institute, p. r. i.
The article shows the case of the best practice in the interdisciplinary management of the Spatial Data Set within River Network Section Model based on excellent cooperation of T. G. Masaryk Water Research Institute, p. r. i., with the Czech Office for Surveying, Mapping and Cadastre and the Czech Hydro-meteorological Institute.
The estimation of the extent of inundations is enabled by methods of physical and mathematical modelling which have been developing for many years. Increasing accuracy, related to precise measurements, demands higher computing capacity and more time.
