Area of Science:
- Environmental Science
- Limnology
- Ecological Modeling
Context:
- Dynamic simulation experiments were conducted at the Taihu Laboratory for Lake Ecosystem Research.
- Water from Taihu Lake was used in an ecological tank to study algae growth.
- Algae growth was observed under varied conditions including temperature, sunlight, and nutrient levels.
Purpose:
- To develop a dynamic algae growth model for Taihu Lake.
- To incorporate nitrogen and phosphorus cycles into the algae growth model.
- To calibrate and validate the model using experimental results.
Summary:
- An advanced PHREEQC model was employed to simulate algae growth, considering nitrogen and phosphorus cycles.
- The model parameters were meticulously calibrated and validated against experimental data using the least square method.
