Evaluation of water regime monitoring in Roklan site
Čejková, E. ; Sněhota, M. ; Tesař, Miroslav ; Dohnal, M.
Contribution focuses on soil water regime in the mountainous site Roklan, which is located in the first zone of the National Park Sumava. Spruce monoculture forest in the location was devastated by bark beetle and then left to natural regeneration. The soil hydrological and meteorological monitoring is performed since 2011. Presented paper reports on soil hydraulic properties of the soil from the site. Then, the TDR water contents data collected in the site are compared with the water content data obtained by calculation from the pressure head data using the known water retention curves. The data for two selected rain episodes are presented in detail and results are discussed.

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.

The use of web 2.0 tools for supporting team collaboration
Dohnal, Martin ; Pavlíčková, Jarmila (advisor) ; Pecinovský, Rudolf (referee)
The purpose of the present thesis is to apprise a reader of issues of tools for supporting team collaboration via web 2.0. These tools allow workmates to effectively collaborate from different geographical locations without the need for organizing time-consuming and often unproductive meetings. For example, such tools support teams in the way that ensures an access to shared documents for all project co-workers. A theoretical part of the thesis aims to introduce select definitions of terms which relates to this tools -- the terms collaboration and web 2.0, and furthermore to give reader an overview of existing tools for supporting team collaboration. A practical part of the thesis is aimed at description of one particular tool in the form of instruction manual which can be used by students in the homework process. The practical part also includes realization of research on student's experience with introduced tools. The research has a form of questionnaire. Finally author evaluates results of the research.

Internal Audit and Risk Management
Luzumová, Martina ; Králíček, Vladimír (advisor) ; Dohnal, Martin (referee)
The goal of the thesis Internal Audit and Risk Management is to analyze Internal Audit in the selected company, to form the process for implementation of Risk Management System and to evaluate software solutions for Internal Audit and Risk Management in the company. The thesis is focused first on the historical development and the Standards for Internal Audit and Risk Management and on the interdependence of these disciplines with Corporate Governance. In the practical part is analyzed Internal Audit and Risk Management function and there are outlined possibilities of the software solutions in the company.

Simulation of water and heat transport considering preferential flow. Experimental site Na Lizu
Votrubová, J. ; Dohnal, M. ; Vogel, T. ; Tesař, Miroslav
Coupled water and heat transport in soil profile at the experimental site Na Lizu (Volynka headwater catchment, Sumava Mountains, southern Bohemia) is studied. The site is located on a mild slope cov-ered with grass. The soil is Cambisol developed upon biotite paragneiss bedrock. One-dimensional dual-continuum model with semi-separate flow domains representing the soil matrix and the network of preferential pathways (S1D) is employed. Hydraulic parameters of the model are set based on labo-ratory retention curve measurements and in-situ measurements of hydraulic conductivity. Thermal pa-rameters are estimated using methodology of Cote and Konrad (2005). Simulation is conducted for the summer season of 2009. The in-situ monitored precipitation and soil surface temperatures are used as the model upper boundary condition. Model performance was evaluated through comparison with soil water pressure and soil temperatures monitored in situ.
