Vyhodnocení ohroženosti pozemků vodní erozí ve vybraném území
Kramář, Radim
The diploma thesis is focused on the evaluation of vulnerability of land to water erosion in the sub-basin of the river Bystřice with the hydrological order number 4-15-01-0402-0-00. The work contains research dealing with soil erosion and erosion protection. Part of the thesis describes the basin of interest on the basis of a site survey and available literature. The principle of erosion risk evaluation is calculation of the universal USLE Wischmeier-Smith equation factors and the determination of the average long-term loss of soil caused by water erosion. Partial analyzes are performed using GIS tools and LS converter 1.0 and Usle2D programs. Appropriate anti-erosion measures are proposed if necessary. The measures are based on the results of the evaluation corresponding to the conditions and possibilities of the area of interest. Part of the thesis contains mapping documentation created by the ArcGIS program.
Sledování kvality vody toku Trnava
Kramář, Radim
The bachelor thesis deals with monitoring water quality in the river Trnava within the year 2014. The first part consists of a literature overview relating to the issue of surface water and the characteristics of the monitored watercourse. The second part presents the techniques of monitoring and evaluation of results. During monitoring, the following water quality parameters were measured in the field: pH, dissolved oxygen, conductivity and temperature. Simultaneously water sample was taken for chemical analyses in a laboratory, in which the content of sulphate, nitrate nitrogen and total phosphorus was determined. The obtained values were evaluated according to CSN 75 7221 Classification of surface water quality and also compared with the values of permissible pollution of surface water Environmental Quality Standards in Government Regulation no. 61/2003.
