Labe IV: Modelování pohybu vody a rozpuštěných látek ve vadózní zóně
České vysoké učení technické v Praze, Fakulta stavební ; Zumr, David ; Votrubová, Jana ; Sněhota, Michal ; Šanda, Martin ; Jelínková, V. ; Hrnčíř, Miroslav ; Dušek, Jaromír ; Dohnal, Michal ; Vogel, Tomáš ; Císlerová, Milena
Výzkumné práce vykonané ve třetím roce projektu týmem Fakulty stavební byly plynulým pokračováním aktivit z prvních dvou let řešení. V souhlase s metodikou byla pozornost zaměřena jednak na další vývoj simulačních modelů a vedle toho na měření a vyhodnocení hydraulických charakteristik. Pokračovaly experimenty určené na posouzení časoprostorové variability nasycených hydraulických vodivostí doplněných geofyzikálním měřením. Intenzivní zapojení studentů inženýrského i doktorandského studia do výzkumu umožnilo věnovat se v této fázi velmi podrobně možnostem zpřesnění popisu dynamiky proudění vody ve vadózní zóně, která je z hlediska transportních procesů determinující pro všechna řešení pohybu polutantů pod zemským povrchem.

Evapotranspiration of selected agricultural and forest species
Kučera, J. ; Urban, J. ; Trnka, Miroslav ; Fischer, Milan ; Krofta, K. ; Duffková, R.
The aim of this article is a comparison of evapotranspiration (ET) of different covers (turf grass, clover (Trifolium pratense), winter wheat (Triticum aestivum), hops (Humulus lupulus) and the high density poplar stand (J-105, Populus nigra x Populus Maximowiczii)) with the potential evapotranspiration (PET) and the general description the ET rates dynamic during the season. The second goal is to quantify the ratio of the transpiration and the whole evapotranspiration for the two contrasting cultures – the hops and poplars stand. The daily maximal sum of the grass ET reached, similarly like for the other species, up to 5–6 mm per day, which comprises 85–93 % of PET. Significantly higher ET was showed by the culture of clover. On the other hand, the lowest values were performed by the poplar stand in the first year after coppicing. The transpiration to evapotranspiration ratio resulted in 40–70 % by the hops and 80–90 % in case of the poplars.

Water balance in short rotation poplar coppice and reference grass-plot in conditions of Czech-Moravian Highlands
Orság, Matěj ; Fischer, Milan ; Trnka, Miroslav ; Hlavinka, Petr ; Kučera, J. ; Balek, J. ; Žalud, Zdeněk
This text presents results of a study focusing on differences of water balance between two contrasting cultures - short rotation poplar coppice and grass plot in conditions of Czech-Moravian Highlands. Actual evapotranspiration (by Bowen ratio energy balance method), precipitation and soil moisture in two layers (0 – 0.45 m and 0.45 – 0.90 m) were measured on both plots during seasons 2008 – 2010. The seasonal water lost through evapotranspiration was higher for the grass (560.4 and 508 mm for grass and 523.8 and 351.8 mm for poplar during growing season 2009 and 2010 respectively), but generally the observed amounts of ETa are comparable for both cultures and within the range of values described in literature. Results of soil moisture measurements expressed as soil water availability [mm] were compared with simulations obtained from water balance model SoilClim. The model a little bit underestimated the amount of available water in the system, since based on water balance closure we suggest that there is a higher water income than was recorded from precipitation. This extra water found in observed systems may be supplied probably by lateral underground water inflow from the upper fields.

Methods of the separation of the base flow and trends of nitrogen concentrations in this base flow
MAIEROVÁ, Monika
This Bachelor thesis is aimed to clarify the hydrological cycle, hydrological balance, groundwater hydrology, the selected basic baseflow separation methods of comparing them and last but not least, nitrogen cycle, nitrogen, nitrates, ammonia nitrogen and nitrogen in groundwater. In the work there is also closely analyzed the total, surface and subsurface outflow and the detailed division. The methods of the groundwater baseflow separation are described with regard to content of nitrogen compounds., which currently create the most common type of pollution of groundwater used as drinking sources.
