Introduction

As you work through this lesson, you will understand the management strategies for the non-karst portion of karst catchments based on the vulnerability of the downstream karst unit.

What are karst catchment areas?

Karst catchment areas are comprised of all lands contributing surface runoff and/or diffuse recharge to the karst system, including upstream non-karst areas.

When and how are karst catchment areas identified?

Karst catchments are delineated during karst inventories. Dye tracing can be used to determine subsurface flow paths, particularly in cases where subsurface hydrological connections cross surface drainage divides.

What is the main management objective for the non-karst portion of a karst catchment?

To maintain the water quality and quantity of streams that sink or lose water into downstream karst units.
