Objective:

A premise of the Center is that successful ecosystem studies require a detailed knowledge of transport and fate processes. The mechanisms and rates of transport of water, air and the dissolved or suspended constituents therein provide the necessary links between "cause" and "effect" in study of ecosystem function. Without such knowledge, some key stressors may go unrecognized or unanticipated. Furthermore, without sufficient knowledge of transport and fate processes, one lacks the scientific basis needed to mitigate impacts on ecosystems through appropriate changes in resource management practices. This has been a limiting factor in applying results of traditional ecosystem research in development of public policy. This project seeks to develop greater understanding for transport and fate.

Approach:

The role of the Transport and Fate Core is two-fold: (1) help characterize and model appropriate transport and fate processes in the Watershed Projects and (2) make improvements in transport and fate models so that the processes and questions relevant to ecosystem studies can be addressed adequately. At the inception of the Center, the investigators were convinced of the important role of transport and fate processes in ecosystem function, but did not yet have sufficient knowledge of exactly what each Watershed Project needed and of the corresponding limitations of existing transport and fate modeling methods. The Center provides a testing ground for fate and transport scientists to define problems, modify and validate models. Through participation in the Center, the Transport and Fate Core investigators have been able to gain experiences in the applied and basic research problems that are relevant to ecosystem function and to direct their work accordingly. Because of traditional research directions of hydrologists, and soil and atmospheric scientists, the interdisciplinary connections summarized below would not have happened without the integrative framework provided by the Center. Such interaction not only advances ecosystem research, it also rejuvenates the research activities in hydrology and soil and atmospheric sciences by revealing previously unrecognized frontiers at interfaces between disciplines.

Expected Results:

This core is expected to result in the characterization and modeling services provided by various projects because the fundamental modeling research applies broadly to all the Watershed Projects.
