Overview

Numerical simulation evaluates grass carp habitat suitability near eco-revetment structure, indicating ecological improvements.

Key Points

  • The study aims to evaluate the impact of a new eco-revetment structure on grass carp habitat suitability in river ecosystems.
  • Conducted numerical simulation using large eddy simulation and fuzzy mathematics theory.
  • Assessed habitat suitability index (HSI) for different life cycles of grass carp in varying flow conditions and vegetation presence.
  • Analyzed flow characteristics and nitrogen phosphorus ratios in relation to habitat suitability.
  • The flow rate is crucial for juvenile grass carp habitat, with HSI in region B improving as flow velocity increases.
  • In vegetated regions, the proportion of low-suitability areas decreases, enhancing overall habitat suitability.
  • Spawning suitability zones are positively correlated with flow velocity, contributing to fish habitat quality.
