The present construction of a road way will link Hrastnik with Zidani Most to ensure the road
to carry heavy traffic. In regard to the construction plans made in the local community an
agreement have been reached for a possible reconstruction of an existing kayaking course in
2007. The paper presents three different solutions for the construction of the kayaking course
based on current worldwide trends.
The necessary data for calculating water surface profiles and discharges were collected. Onedimensional
and two-dimensional models were calibrated with the actual conditions. The
influence of the reconstruction of the course was examined for low and high discharges with
the probability of 10 % (Q10) and 1% (Q100). With the use of the two-dimensional model we
presented the velocity vectors and water surface profiles with different solutions and in
different discharges.
Three propositions for the reconstruction were made: the financially undemanding solution
(example 1), secondly, the construction of a new kayaking channel (example 2), and thirdly
the construction of a kayaking course of worldwide standards of the highest rank (example 3). The new kayaking course as a sport facility would contribute to the higher competition level
of the Hrastnik kayak paddlers and would make possible the organization of an European or
World championship. Thus, the kayaking course would also enhance the tourist awareness of
the town Hrastnik.
