Determination of soil loss from erosion rills by method of digital photogrammetry and method of volumetric quantification
This article presents the first results of the research focused on the recording of rill erosion, and its evaluation using the outputs of the two methods that can be used to determine the soil yield. The consequences of erosion have been documented on a selected pilot site, both as a direct method of volume quantification (using an profile meter – so called soil erosion bridge) and with the use of unmanned aircraft in close-up photogrammetry (UAV).
This article describes part of results of the project “QJ1520268 The new procedures of optimization systems integrated protection area in the context of their economic sustainability“. The aim is effectiveness assessment of the designed measures in the Litava basin in hydrological model created in software HEC-HMS (Hydrology Engineering center – Hydrologic modeling system).
This paper deals impacts of building of water reservoirs on land use changes in floodplains and adjacent areas of three reservoirs in southern Moravia – Nové Mlýny, Vranov, Brno. To monitor the development of land use the old topographic maps were used.
Potential of the nature-friendly measures application for water retention in the landscape and improvement of the ecological status of water bodies
An analysis and assessment of the nature-friendly measures potential for water retention in the landscape were carried out as a part of the work on the concept of protection against drought impacts in the Czech Republic.
The aim of the project “QJ1520268 The new procedures of optimization system integrated protection area in the context of their economic sustainability“ is to create a design optimized system of anagement of water and soil resources in the long term, including balancing the soil‑plant‑atmosphere system and also in order to reduce the impact of climate change on agricultural ecosystem, which is highly topical issue today.
A complex system of flash flood and erosion protection measures was designed for almost 80% of the Czech Republic. It is made mainly from natural water retention measures on agricultural land and water courses.
Under the project New procedures of optimization of integrated protection area systems in the context of their economic sustainability, analysis of plans of collective equipment was done within the complex process of land consolidation based on data from all branches of the State Land Office in the Litava basin.
