New sea level-rise handbook highlights science and models for non-scientists
Coastal managers and planners now have access to a
new U.S. Geological Survey handbook that, for the first time, comprehensively describes the various models used to study and predict sea-level rise and its potential impacts on coasts.
Designed for the benefit of land managers, coastal planners, and policy makers in the United States and around the world, the handbook explains many of the contributing factors that account for sea-level change. It also highlights the different data, techniques, and models used by scientists and engineers to document historical trends of sea level and to forecast future rates and the impact to coastal systems and communities.
The scope and content of the handbook was developed from feedback received at dozens of training sessions held with coastal managers and planners of federal, state, and private agencies across the northern Gulf of Mexico. The sessions aimed to determine what tools and resources were currently in use and to explain the broad spectrum of data and models used in sea-level rise assessments from multiple disciplines, including geology, hydrology and ecology. Criteria were established to distinguish various characteristics of each model, including the source, scale and quality of information input and geographic databases, as well as the ease or difficulty of storing, displaying, or interpreting the model output.
