Jordan River Water Quality Modeling: Application and Simulations

The Jordan River system exhibits significant portions that have been indicated as impaired for different water quality constituents. Consequently, the goal of this study involves evaluating the water quality performance and studies of the Jordan River under existing and futuristic conditions, incorporating land use and climate change projections.

Full Abstract
Significant portions of the Jordan River system are indicated as impaired for different water quality constituents under the “Utah’s 2016 Integrated Report”. At the same time, while previous models have been developed for remediating such impairment, involving the Qual2K Steady-State TMDL February 2007 and August 2009 Models for the Jordan River, further analyses appear needed for investigating the water quantity and quality performance of the Jordan River under existing and futuristic conditions. For this exercise, a major water resources model framework has been developed for investigating the water quantity and quality characteristics of the Jordan River system subject to historical and futuristic development, environmental, and climatic projections. This framework involves DHSVM (Distributed Hydrologic Soil-Vegetation Model) for simulating the non-urban characteristics of the Jordan River Watershed, the SWMM and GoldSim models for simulating the stormwater and urban water quality/quantity of the Jordan River Watershed, and then the WASP (Water Quality Assessment Simulation Program) models for simulating the water quality characteristics of the Jordan River. Under this framework, several simulations are planned for investigating the water quality performance of the Jordan River subject to existing and futuristic climate change projections that are represented by the Representative Concentration Pathways (RCPs) followed by existing and futuristic land use/development scenarios. Such simulations, involving the historical baseline period followed by a futuristic period, provide insight regarding the water quality performance of the Jordan River, with analyses over identifying potential water quality impairment along the system. The objective of this presentation involves discussing the motivation and fundamentals of the Jordan River water quality model (WASP), along with the model setup, water quality constituents simulated, calibration approaches, calibration periods, and the historical baseline/future simulations planned for the project. The presentation first involves general description of the water quality standards for selected water quality constituents by the State of Utah, including discussions of the Jordan River impairment (locations of impairment, constituent impaired, etc.). Then, previous model development, particularly for the WASP Jordan River models, for the Jordan River are assessed, which sensitivity analyses and the calibration approaches, along with analyses of the measured water quality data. This presentation then describes the application of such previous Jordan River model development, which serve as the basis for the extended historical and futuristic simulations planned for the project/research work.
