Hydrologic Modeling, Water Quality Analysis and Conflict Resolution/Avoidance and
Multi criterion Decision Making in Natural Resources Management
Water holds a special position in ecosystem maintenance and management science.
All the biotic and abiotic components within a particular ecosystem are dependent
on water in one way or the other, and the presence of the various ecosystem components
in return affects the quality and quantity of water in the biosphere. Our research
efforts are designed to have a better understanding and develop reliable explanations
for the various relationships between the different ecosystem components. The knowledge
so gained is important for developing state-of-the-art integrated ecosystem management
In all our endeavors, water is studied as a major resource component of forested
and other wildland ecosystems. In this respect its possible influence on the biotic
and abiotic components of an ecosystem are studied in a systems framework. Related
research areas currently in progress or in the planning stage include: modeling
precipitation-runoff relationships in forested environments, analyzing forest and
wildland water quality problems, modeling surface and subsurface contaminant movement
and attenuation processes, and examining climate change scenarios affecting forest
ecosystem conditions. The development and use of appropriate multicriterion decision-making
techniques as tools for holistic ecosystem management is another area of our research
focus. Our aim in this research area is to develop a methodology for selecting the
most preferred management scheme to achieve multi resource outputs and resolve conflicts
among competing decision-makers.
