Modeling the impact of small water reservoirs on flood events
Taufmannová, Alice ; Jeníček, Michal (advisor) ; Daňhelka, Jan (referee)
This paper deals with evaluating the impact of small reservoirs on flood events. The system of small reservoirs represents an effective part of integrated flood protection in the Czech Republic. Its realisation does not require a drastic impact on the environment. The small reservoirs could influence significantly the decrease of flood flows in the mountain catchments. Four small potential uncontrolled reservoirs were implemented to the headwater part of the Rolava river basin (126 km2) in the Ore Mountains. The relief of the Rolava river basin is heterogeneous with the upper headwater part characterised as flat plain and the middle part of the river flowing through a steep valley. The only option of the river to be flooded out during the extreme floods could appear in the lower part of the river basin. The Rainfall-runoff modeling was carried out in the model HEC-HMS (Hydrologic Engineering Center - Hydrologic Modeling System). The advantages of the model are its freeware availability, good arrangement and connection with GIS. The basin model of Rolava was calibrated using the known flood event in September 2007. The verification of the basin model ran on flood event in August 2006. The value of the efficiency criterion between the simulated and measured hydrograph was 0,86 and 0,89, which means successful...

Methods of modelling the runoff from snow cover. Case study: Headwater area of Bystřice River
Hasa, Martin ; Jeníček, Michal (advisor) ; Taufmannová, Alice (referee)
This bachelor thesis deals with the issue of modelling the runoff from melting snow. The main objective is to evaluate two basic methods: degree-day approach and energy balance method. Part of the thesis is the application of degree-day approach in the headwater area of Bystřice River in the Krušné Mountains. Degree day factors were calculated using air temperature and flow rates in the closure profile for the spring snowmelt period in years 2009 and 2010. Degree Day factors were used for modelling the runoff from melting snow. Study results were compared with the findings published in the literature. Key words: temperature index, degree-day approach, energy balance of snow cover, snowmelt modelling
