Possible Correlations Among Simple Visual Disturbance Estimates and Hydrologic and Edaphic Parameters in Forested Headwaters of Mississippi

Author(s): Dewey, J. ;  Ezell, A.;  Palmer, J.;  Choi, B.

Silvicultural BMPs are designed to provide guidelines for maintaining the overall integrity of surface waters by minimizing non-point source inputs of sediment, nutrients and pesticides. Mississippi Forestry Commission guidelines for management of perennial and intermittent stream channels are specific; however guidance recommendations for ephemeral-flow channels are minimal albeit these flow channels are often incipient streams. Measuring the effects of disturbance due to silvicultural activities within and around ephemeral-flow channels on hydrology and soil quality is often time-consuming and cost-prohibitive. This project expands the scope of ongoing research that is currently characterizing the relationships among surface- and subsurface-hydrology, soil physical properties, vegetative communities, and sediment movement in ephemeral-flow and intermittent portions of incipient headwaters in Webster County, Mississippi. Hydrologic and edaphic monitoring began in January of 2007; timber harvesting was conducted in the 4th quarter of 2007; and the site was replanted with loblolly pine in the fourth quarter of 2008. The objective of this study is to characterize disturbance at multiple levels in hydrologically fluid headwater ephemeral areas using a simple visual classification scheme and determine whether correlations exist among observed disturbance levels, surface- and subsurface-hydrology, and selected soil properties.

Responsible Site Design: Implementing Innovative Stormwater Management Strategies

The primary goal of the workshop is to create a dynamic learning experience that examines the role of stormwater management in the built environment. The workshop will focus on integrating ecologically sound water management approaches into site design. After the workshop, attendees will be familiar with the following concepts and technical issues:

  • Knowledge of the stormwater treatment chain
  • Knowledge of the impact of land use codes on stormwater management
  • Application of a design process that mitigates the effects of stormwater on-site
  • Knowledge of the relationship between land use codes and design for innovative stormwater management
