New Paper “Climate Feedback–Based Provisions For Dam Design, Operations, And Water Management In The 21st Century” By Hossain Et Al 2012

We have a new paper under the leadership of Fasial Hossain of the  Department of Civil and Environmental Engineering at Tennessee Technological University,

Hossain, F., A.M. Degu, W. Yigzaw, S.J. Burian, D. Niyogi, J.M. Shepherd and R.A. Pielke Sr., 2012: Climate feedback–based provisions for dam design, operations, and water management in the 21st Century. J. Hydro. Eng., DOI: DOI: 10.1061/(ASCE)HE.1943-5584.0000541, in press.

The conclusion reads in part [highlight added]

The purpose of this article is to shed light on the need for climate feedback-based considerations in dam design, operations, and water management for the 21st century. It first overviewed the known impacts on climate from changes in land use and land cover that are typically anticipated once a dam is constructed. Recent research was presented on the first-order signature around dams on local climate using observational evidence. A global overview of the location of large dams was presented to highlight the need to treat each dam uniquely according to its location and the larger setting. It is now obvious that the observational data associated with current dams, combined with the rich body of research of LCLU impact on climate, can provide the planning and engineering professions with insightful guidance for both operations and more robust dam-building in the 21st century as well as modifications of local design guidelines to account for climate feedback.

The conclusion includes the recommendation that

One way to maximize the ability of future generation of engineers to assimilate knowledge on climate modification for dam design and operations is to enhance the baccalaureate curriculum by adding prerequisite courses on atmospheric sciences and climate.

In this context, we do not mean climate education that starts from the incorrect premise that the human addition of CO2 and a few other greenhouse gases dominate the climate system response in the coming decades. We subscribe to the robust view of the climate system as reported in the 2005 NRC assessment report
