“…These factors have impeded adequate assessment of trends in nutrient concentrations and loadings and effectiveness of management strategies designed to reduce eutrophication. For the Neuse, nutrient loading estimates derived from these concentration and flow data have been used to evaluate the success of management strategies to reduce oxygen deficits, algal blooms, and massive fish kills through targeted reduction Nutrient trends in a large estuary of a total maximum daily load for nitrogen (NC DENR 1999;Reckhow 2003;Wool et al 2003).…”

We used a decadal data set, with weekly to biweekly sampling in April-October and monthly sampling in NovemberMarch, to characterize climatic (hurricane-level storms, a sustained 3-yr drought) and anthropogenic influences on N and P concentrations and loadings to a large eutrophic, poorly flushed estuary, the Neuse Estuary of the Albemarle-Pamlico Estuarine System. Mass volume transport data were obtained with cross-estuary transect flow measurements taken near the entrance to the estuary. Although trends were minimally influenced by hurricanes, analyses were significantly affected by the sustained drought near the end of the study. As examples, decreasing trends in total N (TN), total P (TP), and bottom-water dissolved oxygen concentrations, and in TN loadings were significant considering all data, but these trends were not significant when the sustained drought was excluded from analysis. In addition, the trend in TN loading was especially sensitive to the initial sampling period. NH concentrations dramatically increased (overall by ϳ500%) as a ϩ 4 persistent trend regardless of attempts to control for climatic events. An increasing trend in NH also was documented ϩ 4 in an adjacent, rapidly flushed Coastal Plain estuary, the Cape Fear. The NH data suggest a regional-scale effect of high ϩ 4 inputs from inadequately controlled, increasing nonpoint sources. The fragility of TN loading trends, the striking increase in NH concentrations, and the lack of management emphasis on controlling nonpoint sources such as ''new'' industri-ϩ 4 alized swine production collectively do not support recent reports of achievement of a 30% reduction in TN loading to the Neuse. Nonpoint sources remain a critical target for reduction to alleviate the negative effects of cultural eutrophication in this system, as in many estuaries throughout the world.

“…Based on the prior experience and following earlier examples of successful coupling between WASP and other hydrodynamic models (Kim, Lim, and Cerco, 2011;Wool, Davie, and Rodriguez, 2003), a one-way offline (executed sequentially, where output from ROMS is passed to WASP for computation of variables) coupler was developed to study water quality of the bay. The hydrodynamic model setup was the same as in Defne and Ganju (2015) and spanned the entire bay ( Figure 1a), whereas only the subdomain covering Toms River embayment ( Figure 1b) was used to build the WASP grid (Figure 1c), which was built to demonstrate the functionality of the coupling with RWC.…”

“…With the addition of the wetting and drying capability , ROMS is suitable for modeling tidal dynamics and water circulation, temperature, salinity, and sediment transport in a shallow, back-barrier estuary. The Water Quality Analysis Simulation Program (WASP; Ambrose et al, 1988;Di Toro, Fitzpatrick, and Thomann, 1983;Wool, Davie, and Rodriguez, 2003), developed by the U.S. Environmental Protection Agency (EPA), incorporates watershed nutrient loading and internal nutrient cycling to calculate dissolved oxygen (DO), oxygen demand, nutrient concentrations, sediment, and phytoplankton dynamics and has been widely used for water-quality and TMDL assessment in rivers, reservoirs, lakes, and estuaries (Abdelrhman, 2015;Camacho et al, 2014;Franceschini and Tsai, 2010;Hosseini, Chun, and Lindenschmidt, 2016;Kaufman, 2011;Lindenschmidt, 2006 and references therein;Tetra Tech, 2012, 2015. WASP can receive hydrodynamic information from other models (EFDC, DYNHYD, RIVMOD, CE-QUAL-RIV1, SWMM) through a binary hydrodynamic linkage file; however, a coupling between ROMS and WASP was not available prior to this study.…”

The Regional Ocean Modeling System (ROMS) has been coupled with the Water Quality Analysis Simulation Program (WASP) to be used in a comprehensive analysis of water quality in Barnegat Bay, New Jersey. The coupler can spatially aggregate hydrodynamic information in ROMS cells into larger WASP segments. It can also be used to resample ROMS output at a finer temporal scale to meet WASP time-stepping requirements. The coupler aggregates flow components, temperature, and salinity in ROMS output for input to WASP via a hydrodynamic linkage file. The coupler was tested initially with idealized cases designed to verify the water mass balance and conservation of constituent mass using oneto-one and one-to-many connectivity options between segments. A realistic example from the Toms River embayment, a subdomain of Barnegat Bay, was used to demonstrate the functionality of the coupling. A WASP eutrophication model accounting for dissolved oxygen (DO), nitrogen, and constant phytoplankton concentrations was applied to explore the distribution and trends in DO and nitrogen in the embayment for the period of July-August 2012. Results of DO modeling indicate satisfactory agreement with measurements collected at in-bay stations and also indicate that this coupled approach, despite substantial differences in spatiotemporal discretization between the models, provides adequate predictive capabilities.

“…For example, distributed hydrological and hydrodynamic models, such as SWAT (Soil and Water Assessment Tool), HSPF (Hydrological Simulation Program Fortran), AGNPS (agricultural non-point source pollution model) and WASP (Water Quality Analysis Simulation Program), are all geared with management modules for the simulation and evaluation of management effects on flow, sediment and nutrients [2][3][4][5][6]. Although great achievements have been gained by these models, the complex model structures and interfaces have impeded their applications by inexperienced users.…”

Using distributed hydrological models to evaluate the effectiveness of reducing non-point source pollution by applying best management practices (BMPs) is an important support to decision making for watershed management. However, complex interfaces and time-consuming simulations of the models have largely hindered the applications of these models. We designed and developed a prototype web-based decision support system for watershed management (DSS-WMRJ), which is user friendly and supports quasi-real-time decision making. DSS-WMRJ is based on integrating an open-source Web-based Geographical Information Systems (Web GIS) tool (Geoserver), a modeling component (SWAT, Soil and Water Assessment Tool), a cloud computing platform (Hadoop) and other open source components and libraries. In addition, a private cloud is used in an innovative manner to parallelize model simulations, which are time consuming and computationally costly. Then, the prototype DSS-WMRJ was tested with a case study. Successful implementation and testing of the prototype DSS-WMRJ lay a good foundation to develop DSS-WMRJ into a fully-fledged tool for watershed management. DSS-WMRJ can be easily customized for use in other watersheds and is valuable for constructing other environmental decision support systems, because of its performance, flexibility, scalability and economy.
