Management of the Headwater Area of Jihlava River
 Sviták, Jan ; Syrovátka, Oldřich (advisor) ; Duchek, Stanislav (referee)
This Bachelor work deals with the management of the headwater area of the Jihlava River. The work is based on the detected state of the headwater area of the Jihlava River, which is currently very ecologically unstable from the reasons of the improper regulations and agricultural interventions. This situation is described and evaluated in the work. On the base of the results such corrective measures are suggested, which lead to ecological stability increase in the headwater basin, especially regarding drainage conditions. This measures can serve as the base for the initiation and realization of comprehensive landscape adjustments. For these purposes the management of the individual municipalities will be asked for their opinion regarding the realization of the comprehensive landscape adjustments.

Formování odtoku v revitalizované podhorské pramenné oblasti v Senotíně
 Tesař, Miroslav ; Syrovátka, O. ; Lichner, Ľ.
The purpose of the Senotín pilot project (1993–2000) was to determine methods of revitalisation of a sub-mountain headwater area (0.38 km2) in the Novobystřická Vysočina Highlands (610–725 m a. s. l.). Seven underground clay shields stopped pipe drainage, and four balks prevented surface and subsurface runoff. These adaptations improved the water retention capacity of the whole catchment, as demonstrated by the formation of runoff in the revitalised area. A typical rainstorm (amount 15 mm, duration 5.6 hours, max. intensity 1.8 mm/20 minutes) and consequent runoff was analysed, along with the role of soil in runoff retardation and water retention. The time course of the contributing area was also quantified. The contributing area was formed in the surface soil layer with a thickness of about 40 cm. Runoff retardation lasted two hours after the rain began. Retention reached 98% of the total rainfall. Runoff lasted for 85 hours.
