Abstract
defining the relevant flood waters for proportioning hydro-technical structures and
protection against flood waters.
Due to changes of natural factors and changed conditions under the influence of
anthropogenic factors taking place at already constructed hydrotechnical structures,
redefinition of flood waters is an extremely important measure in forecasting floods and
timely undertaking of corresponding activities for prevention or reduction of their
consequences.
Presented in this paper are the results of the hydrological analysis of the Kalimanci dam
basin carried out for the purpose of redefining flood waters. The analyses of the physicalgeometrical
characteristics of the drainage area carried out by use of DTM (Digital
Terrain Model) and application of SWAT (Soil & Water Assessment Tool), a
hydrological analysis module from the Geographic Information Software (GIS), are
presented further in the text. Flood waters with different return periods will be redefined
by use of statistic methods based on data from measurements of Bregalnica river flow
(1961-2005) and Kamenichka Reka river flow (1986-2005). Shown further in the
paper will be the results of the calculation of the maximum flood waters (MPFMaximum
Probable Flood waters) in the basin. MPF will be calculated by taking into
account a series of data on maximum annual daily rainfall, measured at the dam itself,
in the period 2005 to 2017. The results of these analyses will be presented in a tabular
and graphic form.
