Sample interview questions: How do you assess the impact of agricultural drainage on wetland ecosystems?
Sample answer:
Assessing the Impact of Agricultural Drainage on Wetland Ecosystems
1. Hydrologic Alterations:
- Quantify changes in water levels, flow rates, and timing of water flow using piezometers, stream gauges, and hydrographs.
- Assess the impact on wetland hydrology, vegetation, and wildlife habitat.
2. Water Quality Degradation:
- Analyze changes in nutrient concentrations (nitrates, phosphates), sediment loads, and dissolved oxygen levels using water sampling and monitoring.
- Identify sources of agricultural runoff and assess the effects on wetland water quality and biota.
3. Habitat Loss and Fragmentation:
- Map changes in wetland area, connectivity, and vegetation cover using aerial imagery, remote sensing, and field surveys.
- Evaluate the impact on wetland habitat for wildlife, including nesting and foraging areas.
4. Biogeochemical Processes:
- Measure changes in rates of organic matter decomposition, greenhouse gas emissions, and nutrient cycling using gas flux chambers and laboratory analyses.
- Assess the impact on wetland carbon sequestration an… Read full answer
