Quantification of the impact of rainfall-runoff events on nutrient loads from the watershed
STREITOVÁ, Eva
This diploma thesis deals with clarification of an influence of rain discharge events on nutrients loss from drainage area and which rain discharge events are the main cause of the loss. Within the scope of this the influence of these episodes on drainage area of the Jenínský brook will be quantified, more specifically sub-drainage area J2. The thesis describes not only the circle of water in the nature, specification of rain drainage events origin, but also the very factors which influence the water drainage and the loss of nutrients caused by the drainage. Furthermore, the basic nutrients which appear the most often and in the biggest quantities in our waters are described, these being nitrogen and phosphor and last but not least what is described here is the total loss of nutrients in water during rain drainage events. The description of a drainage area itself and a water intake profile J2 follows. The water intake profile J2 was the source for processing the results. The results were processed by several computational methods, which were compared to each other in the end. The loss during 5 extreme rain events was calculated and so was their percentage representation in the total annual losses and the consecutive evaluation of the results.
Influence of rainfall drainage events on nutrients loss in river basins
STREITOVÁ, Eva
The aim of this bachelor thesis is to clarify the influence of rainfall drainage events on nutrients loss in river basins and which of these rainfall drainage events are the main reason for the loss. This thesis describes the elemental nutrients ( nitrogen and phosporus belong here) occuring the most often and in the biggest amount in our waters. The thesis also describes their occurence in waters and follow-on eutrophication of waters. Further, the factors influencing the drainage during the rainfall event are defined. These factors determine, by their activity, what aliquot part of rainfall drains on the surface, when and in which sequence the individual aliquot parts of rainfall come to river basin, whether water runs off the surface quickly or whether it soaks into the soil. These processes implicate the well-known cycle of water in the nature, which is consequently described in this thesis.
