Featured Series –  SWAT Applications for Emerging Hydrologic and Water Quality Challenges

This is the final installment of a recurring series of papers published during 2017 focusing on the Soil and Water Assessment Tool (SWAT). Merwade et al. provide an excellent overview of the featured series and conclude, “Overall, this featured series gives a glimpse of a wide variety of SWAT applications, ongoing developments, and future capabilities. All the studies in the series reinforce the versatility of SWAT, which will continue to grow and meet the future needs of the user community to address emerging challenges in the hydrologic modeling community.” A few representative papers from the papers in this issue follow.

Pyo et al. developed a multi-objective decision support system for allocating best management practice (BMP) type and placement by coupling the SWAT with an algorithm that minimizes total phosphorus yields.

Habicht et al. used SWAT to investigate how natural gas development could impact streamflow, sediment, total nitrogen, and total phosphorous loadings in the upper Delaware River Basin.

Cibin et al. used SWAT to quantify ecosystem services of bioenergy-based land use change and estimate the potential changes of ecosystem services due to climate change projections.

Panagopoulos et al. used a revised SWAT model with improved biofuel crop representation to address the water quality implications of increased biofuel production.

Other Technical Papers

McMillan et al. evaluated the applicability of the Bank Assessment of Nonpoint source Consequences of Sediment (BANCS) model to the northern Gulf of Mexico coastal plain.

Zhou et al. incorporated root distribution into a soil moisture-based index and evaluated its performance for agricultural drought monitoring.

Dudley et al. developed a logistic regression approach for forecasting the probability of future groundwater levels declining and tested the approach in different climatic regions and aquifers of the United States.

Shen et al. created a screening method able to quickly and inexpensively estimate overtopping risk across a collection of bridges based on current streamflow conditions.

Danner et al. modeled current reservoir operations under plausible future hydrologic conditions.

Fedorchak et al. evaluated the influence of eight stormwater user fees on sources of revenue for two Virginia municipalities.
