AB  - Nowadays, rapid growths of urban areas and associated land use/land cover (LULC) 
      changes notably affect the surface runoff response to rainfall in urbanised 
      catchments. This effect of urbanisation on surface runoff is frequently addressed 
      since it relates to the increasing incidence of pluvial floods worldwide. Studies 
      on this issue commonly assess runoff changes over several most recent decades. 
      However, human-induced factors likely resulted in increased surface runoff and 
      associated flash floods in rural catchments even in the past centuries. Such 
      long-term changes have been rarely studied and thus are not well documented. This 
      paper aims to fill this gap and assess the surface runoff response to LULC 
      changes in a small catchment in southwestern Slovakia over more than two 
      centuries. To meet this goal, we applied the Soil Conservation Service Curve 
      Number (SCS-CN) method. We mapped past (1784) and present (2018) LULC classes 
      based on historical maps and modern remote sensing data. Then, we estimated 
      surface runoff depths for specific design rainstorms for both periods by 
      executing CN method equations in the ArcGIS environment. Results revealed 
      significant changes in surface runoff conditions between evaluated periods. In 
      total, surface runoff magnitudes increased by ~230 and ~ 130% for 40- and 65-mm 
      design rainstorms, respectively, compared to 1784. Moreover, surface runoff 
      values show different spatial patterns on historical and present-day output 
      raster images revealing spatial redistribution of runoff-enhancing and 
      runoff-preventing areas during the evaluated period. Although both 
      infiltration-enhancing and runoff-enhancing effects of LULC changes were 
      identified, the latter effect associated with urbanised lowland areas was 
      recognised as prevailing at present. In contrast, runoff-promoting conditions 
      were associated with hilly vineyard areas in the past. These findings likely have 
      important implications for understanding the past and present LULC-based controls 
      of surface runoff generation and flash floods initiation.
