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.
Soil water retention : a basis for landscape revitalization
Syrovátka, O. ; Šír, Miloslav ; Tesař, Miroslav
The purpose of the pilot project Senotín is to create theoretical and methodological basis of revitalization of submountain headwater area, which was drained, ploughed and damaged by unsuitable agricultural practices.
