Climate And Water Resources In The Carolinas: Approaches To Applying Global Climate Change Information To Local Decisions, Kirsten Lackstrom, Gregory J. Carbone, Daniel L. Tufford, Aashka Patel

Journal of South Carolina Water Resources

A wide range of resource managers, community planners, and other stakeholders are increasingly asking for information regarding how climate change will affect South Carolina’s freshwater and coastal resources. They are interested in using this information for decisions related to infrastructure design, water system planning, vulnerability assessments, and ecosystem management. While climate change data, projections, and related information are also becoming increasingly available, many uncertainties around future climate change and its potential impacts often hinder its application. Furthermore it is often not available in a format or at a scale that is easily translated to local- and regional resource management decisions. …

Adjusting Nrcs Curve Number For Rainfall Durations Less Than 24 Hours, Michael Meadows

Journal of South Carolina Water Resources

The primary use of the Natural Resources Conservation Service (NRCS) curve number (CN) is to compute total storm runoff based on total rainfall. The method was originally created to determine the mean daily depth of runoff during flood producing events on small agricultural watersheds. CN values were determined using daily rainfall and runoff data. Practically, it did not rain for 24 hours during many, perhaps most, of the events, but since the data were recorded as daily rainfall, 24 hours became the implicit duration for values input to the curve number runoff model. NRCS references do not specifically state the …

A Policy Lens Of South Carolina Coastal Stormwater Management, Lori A. Dickes, Jeffrey Allen, Monika Jalowiecka, Katie Buckley

Journal of South Carolina Water Resources

Similar to many environmental issues today, stormwater management lies within a network of regulatory and policy oversight. As South Carolina coastal communities continue to experience economic and population growth, understanding the broader policy context of stormwater pond management is important. This study was aimed at compiling the state-of-the-knowledge of stormwater pond management policy for the eight coastal counties of South Carolina. In order to enhance researchers and policymakers understanding of the stormwater policy and regulatory environment, this research utilizes a mixed methods approach. A mixed methods approach allows researchers to explore different components of a particular research question by deploying …

Hydro-Meteorologic Assessment Of October 2015 Extreme Precipitation Event On Santee Experimental Forest Watersheds, South Carolina, Devendra M. Amatya, Charles A. Harrison, Carl C. Trettin

Journal of South Carolina Water Resources

The extreme precipitation event on October 3-4, 2015, likely resulting from the convergence of a persistent deep easterly flow, the continuous supply of moisture, the terrain, and the circulation associated with Hurricane Joaquin off the eastern Atlantic Coast (http://cms.met.psu. edu/sref/severe/2015/04Oct2015.pdf) resulted in extreme and prolonged flooding in many parts of South Carolina. We present the precipitation amounts and intensities observed at four gauges on the USDA Forest Service Santee Experimental Forest (SEF) watersheds during this extreme event in conjunction with the antecedent conditions for 5 days prior to the event. All four rain gauges recorded 24-hr maximum rainfall of 340 …

Development Of Extended Unimpaired Streamflow Records In The Saluda Basin, South Carolina, C. Alex Pellett, John Boyer, Nina Caraway, Tim Cox, Joseph A. Gellici, Scott Harder, Andy Wachob, Kirk Westphal

Journal of South Carolina Water Resources

This paper presents the steps involved and the methodologies employed in the first phase of the South Carolina Surface Water Assessment - development of extended and unimpaired streamflow estimates based on USGS gage data in the Saluda basin. Streamflow data are first adjusted to remove effects of anthropogenic impairments. Adjustments are made for reservoirs, withdrawals, and discharges based on available documentation. Where documentation is insufficient, hindcasting methods are used. The resulting datasets are called unimpaired flows (UIFs).

The UIFs are then extended in time from 1925, the starting date of the first continuous stream discharge data available in the basin, …

The Historic South Carolina Rainfall And Major Floods Of October 1-5, 2015, Hope Mizzell, Mark Malsick, Wes Tyler

Journal of South Carolina Water Resources

A record setting and historic rainfall event occurred October 1-5, 2015, producing widespread and significant flooding across much of South Carolina. The rainfall resulted from several atmospheric and hydrometeorological factors. The record rainfall triggered flash floods and riverine flooding that resulted in emergency evacuations, travel disruptions, personal property damage, business losses, bridge collapses, dam failures and tragic loss of life. Precipitation records were broken from the midlands to the coast, with totals ranging from 10 to over 26 inches of rain. Sixteen National Weather Service Cooperative Weather Stations set new 24-hour rainfall records for October. The amount of rainfall during …

Journal Of South Carolina Water Resources Volume 3, Issue 1

Journal of South Carolina Water Resources

It has been a busy and somewhat tumultuous time for South Carolina’s water resources since the publication of the Journal’s second volume. This past October, Hurricane Matthew caused significant flooding and major property damage throughout a large swath from Beaufort County in the Lowcountry up into eastern North Carolina. The small town of Nichols on the Little Pee Dee River in Marion County was especially hard hit. Residents there continue salvage and recovery work, and dozens of properties were lost. Meanwhile, recovery efforts are still ongoing in many areas from the storm complex of October 2015 which created a historic …
