“…For 1D mathematical simulation of the stream-flow process morphological and geodetic data about the river bed and floodplain of the Ondava River was obtained from water board operator SWME. The necessary hydrological data about the flood wave propagation was achieved by Slovak Hydro-Meteorological Institute (SHMI) [11]. Next data, which was necessary for the hydraulic analysis was about parameters of the realized lateral spillway, which were obtained by own survey.…”

The contribution is dealing with run-off conditions on the lower part of the Ondava River as the capacity of the river bed is insufficient at high flow rates. The reason for the proposed research was the flood situations when protection dikes were breached. For mathematical modeling of flood wave progress, the HEC-RAS software has been applied coupling 1D and 2D modeling procedures. Results of the mathematical model of the surface water level regime in the Ondava River were compared with measured values and afterwards it was used to design further flood protection measures utilizing the existing drainage channel system and pumping stations, as well.

The article describes problems associated with the design of the flood protection measures for small settlements situated at the foot of a mountain. In recent years, these settlements have had problems with flood discharges due to the new development (concreted areas), land/soil management change (private owners farming on their own grounds and do not cooperate together), neglecting of maintenance of surface drains (or their full filling) and river bed channels of the small streams (often dried up during the year, overgrown with woody plants, covered with waste), and of course, also due to climate changes, where the flood discharges are revalued – they are increased. In addition, sub-mountain regions are also characterized by flash floods when a large amount of rainfall falls on a relatively small area with a steeper longitudinal slope. Since the creeks are small there, it could be said to be insignificant, no gauging stations are being built there, so the hydrological data necessary for the design of the flood protection measures are missing. In the article, the procedure of the flood protection measure design for a small sub-mountain area is described which resulted in the design of additional detention reservoirs, complementing the existing detention reservoirs. The HEC-HMS software was used for the hydraulic calculation and the GEOSTUDIO program was used to assess the bank slope stability of the proposed detention reservoirs.

The paper focuses on the impact of climate change on runoff in the Ipoltica River basin in northern Slovakia. The analysis is divided into two parts: the first part contains an analysis of predicted changes in short-term rainfall intensities at the Liptovská Teplička climatological station; the second part is focused on the impact of runoff on a small mountainous river basin. The predicted short-term rainfall intensities were analyzed using the Community Land Model, which is a Regional Climate Model. The analysis was performed in durations of 60 to 1440 minutes for a warm period. The focus was aimed at comparing changes in rainfall characteristics, especially changes in seasonality, the scaling exponents, and design values. The second part focuses on the impact of changes in short-term rainfall on changes in runoff. The estimation of predicted runoff changes was provided for the period 2070 - 2100. These results were compared with the results from actual observations. The design floods were calculated using the Soil Conservation Service - Curve Number method. The results show that the runoff will be affected by climate change. Hence, it is important to reevaluate the land use management and practices at the Ipoltica River basin.
