Although Czech sociology drew its inspiration from literature in the past, and, reversaly, literary science respected the development of mpdern sociolgy, no systematic work from the area of "sociology of literature" has ever been published, though there was one written. In 1940s Karel Krejčí wrote a short text under the title Sociology of literature and published it as an inhouse text in 1944. Krejčí holds a position, which is still up-to date, no matter how it might have been conditioned by his time: sociology of literature is an independent discipline, with a claim to have a place within the system of other sociological fields, that means, he holds a view now very often disputed alamode. The other evident merit of Krejčí´s book is the fact that it anticipated some themes, which were captured by sociological interest much later - especially the theme of so-called "popular literature", "colonial literature", and "literature for women".
The water structures Hričov - Mikšová - Považská Bystrica are a group of channel hydro power plants (HPP) on the Váh Cascade. Modelling methods verified on other channel hydro power plants are easily applicable in their case. In 2006 were by our department provided terrain measurements and hydraulic research on these water structure systems. The results of measurements were used for the better calibration of hydro dynamical model of these power plants. The presented paper describes this process.
