This paper presents the SWAT-MOEA, a user-friendly standalone tool, which couples the Soil and Water Assessment Tool (SWAT) with a Multi-Objective Evolutionary Algorithm (MOEA) to determine Pareto optimal solutions for sustainable watershed management within a reasonable timeframe. The SWAT-MOEA is unique compared with existing tools in that it is publicly available for download along with a manual, it is user customizable, and can be used for studies of varying spatial scales from field to very large watersheds and daily to annual temporal scales. This integration enables simultaneous optimization of multiple objectives for existing SWAT projects. The tool identifies the placement of management strategies that achieve optimal trade-offs among competing objectives. Key SWAT-MOEA features include the ability to create and execute management practices directly through the SWAT-MOEA interface and to select objectives that reflect regional priorities. Results are stored in Excel for efficient display. SWAT-MOEA creates and stores Pareto graphs and geospatial maps of suggested solutions. A case study in the Fort Cobb Reservoir Experimental watershed located in Oklahoma is provided to demonstrate its use.

Future TP loads could change by −8% to +140%, with decreases attributed to LULC transitions from high-use fertilizer agriculture to low/medium density residential classes. Projected TN loads are more consistent, with simulated changes of −1% to +26%. Among LULC transitions, the largest increases in TP and TN are caused by potential urbanization of freshwater wetlands. This study provides knowledge relevant to regions undergoing similar urbanization trends, enabling managers to make better land development plans with water quality considerations.

A comprehensive framework is introduced, which includes a pre-release model categorizing reservoirs based on system characteristics and simulates multiple operational scenarios. Using historical data and simulations for 11 reservoirs managed by the USACE Louisville District, the effectiveness of different operational policies is evaluated. Key findings indicate that pre-release operations, particularly with a 72-h lead time, significantly improve reservoir flood control by reducing end-of-flood water levels and shortening the recovery times for design seasonal flood events. A 24-h pre-release policy is identified as a practical solution, offering substantial improvements with low adverse impacts, making it suitable for regular implementation. Additionally, other operational strategies are assessed, and pre-release is suggested as the optimal approach for facilitating the transition of reservoirs from single to multi-purpose functions. This study underscores the importance of integrating flood forecasting with reservoir operational strategies, advocating for the refinement of release policies to account for unique reservoir conditions.

To that end, we couple streamflow forecasts from the NWM to a gradient-boosted decision tree algorithm (LightGBM) trained on 5+ years of high-frequency monitoring data to forecast in-stream turbidity levels in the Catskill Mountains, NY, USA. Results indicate LightGBM models are capable of relatively skillful predictions, which enable robust forecasts for 1–3 days lead times. LightGBM models offer improvements over a simplified linear model across the entire forecast horizon, and more spatially complex models are more resilient to error at shorter lead times (1–3 days). Moreover, interpretation of model features emphasizes high flows as a driver of turbidity in the region. Results suggest that interpretable, flexible, and efficient machine learning algorithms can produce capable water quality forecasts from streamflow forecasts and expand understanding of process dynamics.
