Use of bottom sediments 

In order to find out the method of evaluation of bottom sediments, it is necessary to ensure accredited sampling of sediments, analytical control of sediments with a focus on dangerous properties. Based on the results of the analyses, an expert opinion on

Mowing of aquatic vegetation 

Vegetation in the vicinity of water bodies affects light conditions by shading, reduces the supply of soil particles to the water environment by wind action, protects banks and drains nutrients.  In the case of water bodies with no or minimal water flow,

Water surface survey

In the process of planning the revitalization of water bodies, the first steps are to determine the current state and survey of the water body. The required data are, in particular: the total volume of sediment in situ, in the water area, or in the design

Natural water environment: Sediments in the hydrographic system II.

Human activity has a significant impact on the water environment and sediment dynamics. Direct human interference is mainly the mining of gravel and sand, either for the purpose of obtaining building materials or for the purpose of deepening the river-bas

Natural water environment: Sediments in the hydrographic system I.

We define sediments as solid mineral materials such as gravel, sand and also as particles of biological material the remains of fallen leaves. The dynamics of sediments consists of three processes: creation, or entry of sediments into the environment, mo
