Keywords:

  • work of water - runoff generation, overland flow and erosion on hillslopes;
  • runoff, generated by three basic mechanisms;
  • conceptual structure - of rainfall–runoff processes;
  • subsurface pipe formation - delivering runoff rapidly, from slopes to channels;
  • infiltration, critical threshold - in understanding runoff generation;
  • factors, affecting infiltration - controls at surface–atmosphere interface;
