🎯 Purpose

The report provides a comprehensive review of tools used to model the fate and transport of nutrients (mainly nitrogen, phosphorus, TSS) within watersheds. Its primary goal is to guide decision-makers, researchers, and watershed managers in selecting and applying models appropriate to their data, objectives, and watershed conditions.

🔍 Evaluation Criteria

Each tool was evaluated based on:

• Purpose and application context

• Pollutants simulated (nutrients, sediment, etc.)

• Spatial and temporal scale

• Ease of use and user expertise required

• Data input needs

• Calibration/validation capabilities

• Strengths and limitations

✅ Key Findings

No one-size-fits-all tool/model selection should depend on:

• Project goals (screening vs. detailed simulation)

• Available data and resources

• User experience

• Geographic and temporal scope

• Simple models are good for screening and planning, while complex models support regulatory assessments, BMP evaluation, and long-term forecasting.

• Uncertainty analysis, model calibration, and validation are crucial for credible results.

🔄 Recommendations

• Match model selection with specific project needs.

• Improve documentation, transparency, and inter-model comparisons.

• Encourage the integration of real-time monitoring data, remote sensing, and machine learning to improve accuracy and usability.

• Support collaborative, cross-agency use of standardized tools for better regulatory and restoration planning.
