Influence of Landscape and Climate Changes on the Maximum Discharge of Small Catchment Areas

The safety of hydraulic structures in small catchment areas is addressed. A procedure for assessing the influence of climate and landscape changes on the maximum discharge that determines the sizes of structure elements is developed. The data from a network weather station and the landscape characteristics of the catchment area were analyzed using statistical methods and geoinformation technologies. The main results are the increase in the maximum daily precipitation and landscape changes over the past decades and their influence on the maximum discharge obtained using probability theory and runoff theory.
