Hu, Y., Long, C.M., Wang, Y.C., Kerkez, B. and Scavia, D.* (2019). Urban Total Phosphorus Loads to the St. Clair-Detroit River System. Journal of Great Lakes Research (in press).
We analyzed the spatial and temporal dynamics of total phosphorus loads from the urban areas in the Detroit River watershed, and used a calibrated storm water management model (SWMM) to explore options for reducing loads around metro Detroit.

Scavia, D*, Bocaniov, S.A., Dagnew, A., Hu, Y., Kerkez, B., Long, C.M., Muenich, R.L., Read, J., Vaccaro, L., Wang, Y.C. (2019). Detroit River Phosphorus Loads: Anatomy of a Binational Watershed. Journal of Great Lakes Research (in press).
The focus of this paper is the Detroit River and its watershed, a source of 25% of the total phosphorus (TP) load to Lake Erie. 54% of the load comes from Lake Huron, and nonpoint sources contribute 57% of the TP load and 50% of the dissolved reactive phosphorus load, with the remaining balance from point sources.

Hu, Y*., & Beattie, S. (2018). Role of Heterogeneous Behavioral Factors in an Agent-Based Model of Crop Choice and Groundwater Irrigation. Journal of Water Resources Planning and Management, 145(2), 04018100.
An agent an agent-based model is developed using a two-stage optimization strategy with the goal of optimizing the decision making of heterogeneous farmers on crop choice and groundwater irrigation.

Hu, Y., Scavia, D., & Kerkez, B*. (2018). Are all data useful? Inferring causality to predict flows across sewer and drainage systems using directed information and boosted regression trees. Water research, 145, 697-706.
Our approach, based on Directed Information (DI) and Boosted Regression Trees (BRT), is evaluated by fusing measurements and the outputs of a numerical sewer model to predict flows across sewer and drainage systems.

Hu, Y*., Quinn, C. J., Cai, X., & Garfinkle, N. W. (2017). Combining human and machine intelligence to derive agents’ behavioral rules for groundwater irrigation. Advances in water resources, 109, 29-40.
An agent-based model is developed based on the behavioral rules represented by directed information graphs and modeled by boosted regression trees, and coupled with a physically-based groundwater model to investigate the impacts of agents’ pumping behavior on the underlying groundwater system in the context of coupled human and environmental systems.
