Impact/Purpose:
The primary objectives of this research are to:
- Provide information on the variability in water supply that can be expected under varying climatic conditions. Early efforts will be focused on assembling regional databases for at least two counties (Mecklenberg County and York County) within SEQL region that can be used for water supply generation and model development.
- Develop tools that will help improve our ability to evaluate, study, and model linkages between different types of environmental systems: hydrologic, geomorphic, ecological, and climatic.
- Explore the use of annual and seasonal measurements of large lake surface temperatures as a new ecological indicator of the overall thermal content of those lakes, and construct an estimator of seasonal large lake heat budgets.
Description:
Landscape characteristics exert their impact on the processes occurring in river basins in many directions and may influence in a different way the environmental security and some related constraints like extreme natural events. The complex nature of landscape structure and dynamics requires that the systematically oriented, methodological approach to their investigation is applied, i.e. the DPSIR (Driving forces, Pressures, State, Impacts, and Responses). This approach is applicable at different levels of the systems and in environmental assessment of river basins in particular. The objective of the present work is to analyze the role of landscape in the PSI (Pressure, State, and Impact) relationships using a system of landscape and hazard indicators and some assessment tools like Automated Geospatial Watershed Assessment (AGWA) and Analytical Tools Interface for Landscape Assessment (ATtILA).
