The project will focus on developing data collection and management, data analysis, and modeling tools that will improve our ability to predict the occurrence and onset of harmful algal blooms (HABs) in reservoirs in Utah and the Intermountain West and to assess the efficacy of reservoir management and nutrient control efforts to mitigate the negative impacts of HABs on public health and drinking water quality.

Dissolved organic matter (DOM) plays an important role in the aquatic environment and can have significant effects on aquatic organisms. Characterizing the composition of DOM within urban receiving waters and the contributions of DOM from urban stormwater runoff is important for understanding potential downstream water quality effects. We conducted this study to characterize the DOM in an urban water conveyance that receives stormwater inputs during runoff events.

Utah State University Spring Runoff Conference

The hydrology of urban stormwater catchments can experience high-volume runoff events and shorter times to peak discharge due to developed landscapes and impervious areas. As a result, TSS and TP pollutant loading events are of short duration and can produce high in-stream concentrations. These pollutants are harmful to aquatic life, reduce reservoir and conveyance capacities, and damage other mechanical equipment.

Dissolved organic matter (DOM) in the aquatic environment originates from living and decaying organisms and anthropogenic sources. DOM plays a significant role in the availability of dissolved nutrients, sequestration of metals from the environment, and optical properties in aquatic ecosystems, all of which affect aquatic organisms. For example, DOM can change water clarity, introduce stresses from oxygen demand, and ultimately impair aquatic ecosystems.

Development of a Water Quality Mobile Monitoring Platform and Techniques for Managing Resulting Data

Water quality monitoring efforts typically involve the measurement of variables at fixed locations. With in situ sensors, high temporal resolution can be achieved, but spatial resolution is not captured. A mobile monitoring platform has the potential to observe fine scale spatial variability of water quality in streams or lakes to identify spatial hot spots and constituent sources, and to inform fixed monitoring efforts.

National Nonpoint Source Monitoring Workshop

Water quality in urban streams and stormwater systems is highly dynamic. In-stream concentrations of common pollutants, such as total suspended solids (TSS) and total phosphorus (TP), can change drastically during storm events. Continuous and unbiased pollutant load estimates require water quality and quantity measurements at a frequency less than or equal to the watershed’s response time, which may be on the order of minutes.

American Geophysical Union (AGU) Fall Meeting

Data and models used within the hydrologic science community are diverse. New research data and model repositories have succeeded in making data and models more accessible, but have been, in most cases, limited to particular types or classes of data or models and also lack the type of collaborative, and iterative functionality needed to enable shared data collection and modeling workflows.
