Overview

Randomized trial demonstrates karst distribution in a watershed, highlighting groundwater resource management.

Key Points

  • This study aims to investigate karst distribution characteristics under varying topographic conditions in a watershed to inform groundwater management.
  • Conducted 10 ERT survey lines across dip slopes, anti-dip slopes, and high-lying depressions in the Chenqi watershed.
  • Utilized 2D/3D ERT inversion and geological drilling for subsurface analysis.
  • ERT effectively detected heterogeneous and discontinuous karst features.
  • Karst water dynamics revealed conduit-type karst in middle slopes and runoff-dominated flow on dip slopes, while infiltration prevails on anti-dip slopes.
  • Average karst zone thickness ranged from 2.0 to 4.0 m, with a maximum of 12 m.
