Methods of the baseflow separation and trends of phosphorus concentrations in this runoff

The aim this bachelor thesis is to clarify the separation of streamflow at the individual components, describe their genesis, hydrological cycle and water balance. Furthermore, the thesis is specifically focused on the groundwater discharge component - baseflow . There are described some of the baseflow separation method. They are a method of empirical, methods based on graphical separation of streamflow hydrograph, methods that use a digital filter to separate the daily streamflow time series, methods that take into account of groundwater level or methods based on the analysis of natural isotopes and chemical substances and so on. There are many methods for the separation of the baseflow, and they are continously developing or are creating new and their results are often very different. There is also concentration of phosphorus and phosphates in groundwater and transfer of phosphorus by groundwater discharge into surface streams mentione
