S.C. Water Resources Conference

Water resource education occurs at many different levels. This ranges from K‐12 education to teachers to adults. At the University of Georgia (UGA), the authors have been working for years to educate the public on water issues ranging from the water cycle to soil erosion and deposition to improving soils for water resource management. The water cycle is one of the standards at the elementary school level. The authors have use an 8X10 foot display of the water cycle to teach students the different phases of the cycle, how they interact and how they are connected. Not only are the …

Effect Of Spatial Distribution Of Precipitation Data On Temporal And Spactial Uncertainty Of Swat Output, Ali O. Alnahit, Abdul A. Khan, Tom O. Owino

S.C. Water Resources Conference

Accurate modeling of water quality, water availability, and transport of pollutants at the watershed scale requires an accurate representation of the precipitation data. For this reason, the ability of hydrologic models to predict accurate outputs depends to a great extent on how well the rainfall data is distributed.

In general, rainfall intensities can vary in space and time, particularly in convective events. A number of schemes are available to account for temporal and spatial uncertainties of precipitation data. The simplest method is the arithmetic mean, which assumes the rainfall is uniformly distributed over the watershed. The Thiessen polygon method is …

Water Quality Effects Of Floating Treatment Wetland Systems To Remediate Plant Production Runoff, Lauren Garcia Chance, John C. Majsztrik, Natasha L. Bell, Daniel Hitchcock, Sarah A. White

S.C. Water Resources Conference

Plant production in greenhouse and container nurseries typically generates runoff water with excess nutrients. Runoff water either flows offsite or is captured and reused for irrigation. Floating treatment wetland systems (FTWs) can remove nutrients from water streams prior to release or reuse. FTWs consist of a floating mat planted with wetland plants, which encourage the growth of microorganisms to remove nutrients from the water.

Clemson Wow Project: Successes Of A Water Quality Outreach Program, Lauren Garcia Chance, Erica Linard, Christie Sampson

S.C. Water Resources Conference

Storm Event Analysis At Nested Watershed Scales: Turkey Creek, Santee Experimental Forest, South Carolina, Austin Morrison, Timothy J. Callahan, Devendra M. Amatya, Vijay M. Vulava, J. Wesley Burnett

S.C. Water Resources Conference

Coastal areas are expected to see the greatest impact on water resources due to population increase and land development affecting the regional water budget by reducing evapotranspiration, groundwater recharge/discharge, and increase runoff. This project inspected forested watersheds in coastal South Carolina to understand their stream response to storm events. The objectives of this study were to (1) characterize the watershed conditions based on their land use/land cover, soil drainage class, and topography, (2) compare streamflow patterns using seasonal event hydrographs, and (3) compare results of analytical method of storm event hydrograph separation with that of the chemical method using stable …

Evaluating A Commercial Potassium Humate Product For The Reduction Of Bioavailable Copper And Zinc In Surface Water, Erin J. Peck, S. Michele Harmon Phd

S.C. Water Resources Conference

Dissolved Organic Matter (DOM) is a crucial component in aquatic systems for the natural remediation of metals pollution. Natural organic compounds from DOM provide macromolecules which strongly attract cations such as copper, lead, zinc, and mercury. Binding with organic molecules reduces toxicity and bioavailability for metals uptake in aquatic organisms. We investigated the use of a commercially-available organic product, Borregro HA-1, to aid in metals remediation in an aquatic environment

A Multiple Method Approach To Evaluate Landward Migration Of Seawater Intrusion In The Floridian Aquifer, Mikala Randich, Tim Callahan, Brooke Czwartacki

S.C. Water Resources Conference

The Floridan aquifer of the Southeastern United States is an important freshwater resource for private and commercial groundwater users. Within the past few decades, certain parts of the aquifer have experienced saltwater intrusion, which has affected the viability of this critical freshwater resource. Groundwater withdrawals, variability in recharge and discharge rates, and sea level rise has caused saltwater to advance into this and other freshwater coastal aquifers. While the South Carolina Department of Natural Resources (SC DNR) monitors conductivity in several coastal Floridan aquifer wells, a comprehensive hydrochemical saltwater intrusion study of the aquifer in the Berkeley-Charleston-Dorchester tri-county region of …

South Carolina Stormwater Detention Ponds: Sediment Accumulation And Nutrient Sequestration, William Schroer, Claudia Benitez-Nelson, Erik Smith, Lori Ziolkowski

S.C. Water Resources Conference

Stormwater detention ponds are prevalent across South Carolina and receive runoff waters carrying both nutrients and sediments. As sediments accumulate in these ponds, water volume is reduced leading to a decrease in runoff retention. Periodic dredging is required to maintain pond function, but dredging is costly and there is little data available to support how often pond dredging is required. It is further unknown how high nutrient loading effects sediment nutrient sequestration and autochthonous production of organic sediment components.

Enhancing Stormwater Public Education And Involvement Efforts Through Undergraduate Student Internships And Projects, Lisa Swanger

Impact Of Economic Trends And Disparities On South Carolina Children’S Health And Well-Being: An Analysis Of The 2016 Kids Count Profile, Arelis Moore De Peralta, Bonnie Holaday

Publications

There are many approaches to conceptualizing and measuring the well-being of children. These indices vary considerably depending on the goal of the scale. However, all of these indices share similar characteristics in that they are multi-dimensional and take into account the complexity of children’s lives. One of the best known of these measures is the Annie E. Casey Foundation’s national KIDS COUNT Data Book (http://www.aecf.org/resources/the-2016-kids-countdata-book/). Each year since 1990 the Casey Foundation has released the KIDS COUNT Data Book. This data provides key information about dimensions of child well-being in the following areas: health, education, economic well-being and family and …

Obstacle Filtering Alogrithm For Control Of An Autonomous Road Vehicle In Public Highway Traffic, Qian Wang, Beshah Ayalew

Publications

This paper presents an obstacle filtering algorithm that mimics human driver-like grouping of objects within a model predictive control scheme for an autonomous road vehicle. In the algorithm, a time to collision criteria is first used as risk assessment indicator to filter the potentially dangerous obstacle object vehicles in the proximity of the autonomously controlled vehicle. Then, the filtered object vehicles with overlapping elliptical collision areas put into groups. A hyper elliptical boundary is regenerated to define an extended collision area for the group. To minimize conservatism, the parameters for the tightest hyper ellipse are determined by solving an optimization …

Noncrossing Partitions, Toggles, And Homomesies, David Einstein, Miriam Farber, Emily Gunawan, Michael Joseph, Matthew Macauley, James Propp, Simon Rubinstein-Salzedo

Publications

We introduce n(n−1)/2 natural involutions (“toggles”) on the set S of noncrossing partitions π of size n, along with certain composite operations obtained by composing these involutions. We show that for many operations T of this kind, a surprisingly large family of functions f on S (including the function that sends π to the number of blocks of π) exhibits the homomesy phenomenon: the average of f over the elements of a T -orbit is the same for all T -orbits. We can apply our method of proof more broadly to toggle operations back on the collection of independent sets …

Situating Computer Simulation Professional Development: Does It Promote Inquiry-Based Simulation Use?, Amanda L. Gonczi, Jennifer L. Maeng, Randy L. Bell, Brooke A. Whitworth
