Sand capping effectively controls phosphorus release from lake sediment by slowing oxygen depletion. This method stabilizes phosphorus, making it less available and improving water quality.

Area of Science:

  • Environmental Science
  • Limnology
  • Water Quality Management

Background:

  • Lake sediment is a significant internal source of phosphorus, contributing to eutrophication.
  • Controlling internal phosphorus loading is crucial for restoring lake ecosystems.
  • The sand capping technique is a potential method for mitigating phosphorus release.

Purpose of the Study:

  • To experimentally evaluate the effectiveness of sand capping in controlling phosphorus release from lake sediment.
  • To assess the impact of different sand cap thicknesses on water quality parameters.
  • To develop an empirical model for estimating oxidation-reduction potential from dissolved oxygen.

Main Methods:

  • Experimental setup using acrylic columns with varying sand cap thicknesses (0, 40, 80 mm).

  • Monitoring of dissolved oxygen, oxidation-reduction potential, total phosphorus, and phosphate in overlying water.
  • Development and application of an empirical model relating dissolved oxygen and oxidation-reduction potential.

    • Main Results:

    • Sand capping significantly slowed down dissolved oxygen depletion in the overlying water.
    • Total phosphorus release from the sediment was effectively controlled by the sand cap.
    • Phosphorus was found to exist in a more stable form within the capped sediment.

    Conclusions:

    • Sand capping is an effective technique for reducing internal phosphorus loading from lake sediments.
    • The presence of a sand cap promotes the stabilization of phosphorus, limiting its bioavailability.
    • Consideration of sediment disturbance during field implementation is essential for successful sand cap construction.
