Factors affecting the total outoff from the watershed and its individual components
MORAVCOVÁ, Lenka
This thesis is focused on the topic of total outflow from the watershed. In the first part water is divided into surface water, subsurface and groundwater, there is also described water circulation, hydrological balance, water retention and water accumulation, as well as characteristics of hydrographic network in the country. There are listed and explained outflow folders and measures to reduce surface runoff. In the second part of this work methods of separating the individual components of outflow, such as CN-method, Kliner and Kněžek method, model SMODERP, HYDROG model, GROUND and MGPM methods are described. In the conclusion it is explained that outflow from the watershed generates not only because of rainfall, but also due to geological, pedological, anthropogenic and other factors.

Base flow-separation method, factors affecting the incidence and size
VLASÁK, Ivo
This bachelor thesis focuses on hydrological cycle, hydrological balance and hydrology of underground waters. Underground waters holding in a river stream is one of the most important characteristics of hydrological mode of a river. Underground waters proportion is detected from a line of flow rate in the course of many years via so called separation of underground river stream. There are several methods of separation and problematics of these methods is described in detail in this thesis. What is mentioned further are the factors influencing occurance and size of an elemental outflow rate, these factors being in particular climate, geology,relief of land, vegetation and last but not least human aktivity. Outflow rate which comes through the cycle of underground waters can be considered as an elemental outflow rate. Outflow rate is a subject matter of a further chapter. Water flowing out in a form of an elemental outflow rate creates both surface and underground waters, which are constituents of a cycle of water in the nature, which is described in this thesis in a detail together with surface, underground and subsurface water.
