Sample interview questions: What are some of the challenges in managing water quality in river deltas, and how would you address them?
Sample answer:
Challenges in Water Quality Management in River Deltas:
- Saline intrusion: As sea levels rise due to climate change, saltwater moves further upstream into deltas, affecting freshwater availability and ecosystem balance.
- Nutrient pollution: Agricultural runoff, sewage discharge, and industrial effluents contribute excessive nutrients to delta waters, leading to eutrophication and algal blooms.
- Sedimentation: Degraded riverbanks and increased erosion from upstream sources result in excessive sediment loading, clogging waterways and smothering aquatic life.
- Habitat degradation: Alterations to river flow patterns, construction of dams and levees, and urbanization can disrupt natural habitats and affect water quality for sensitive species.
- Climate change: More frequent and intense storms, rising temperatures, and changes in precipitation patterns can alter water quality dynamics and exacerbate existing challenges.
