Louisiana Coastal Geohazards Atlas Planned
La. Geological Survey, N.O. Geological Society lead application of landforms base map
BATON ROUGE – Maps, either on paper or accessed electronically, display information that is useful for where people live, work and recreate. Geologic maps are used to find and produce mineral and energy resources and to reveal landscape characteristics that support our economy and shape our lifestyles. Nowhere is this more evident than in Louisiana, where energy resources have enabled our economy, and dynamic river and coastal processes that constructed our coastal area continue to be factors influencing our lives. Flooding, subsidence and faulting, for example, have affected the present landscape and continue to affect people today.
The Louisiana Geological Survey, or LGS, and the New Orleans Geological Society have joined to lead the development of a Louisiana Coastal Geohazards Atlas. The focus will be on the landforms developed in a variety of underlying geologic settings and which are affected by faulting, subsidence and flooding. The atlas will have a landforms base map that will provide useful information for technical analysis and use by governments, the private sector and informed citizens in planning land use and infrastructure development.
“While much work has been done to better understand these processes, the results have not been compiled and combined in a format that brings them together to portray their influences on the coastal plain of south Louisiana,” said Chip Groat, LGS acting director. “The atlas will serve as a valuable resource to our state and region.”
Groat will serve as administrator of the project, and Chris McLindon, president of the New Orleans Geological Society, will share in project oversight. John Johnston III of LGS will serve as editor and coordinator of the participants.
Compiled information will be on the coastal landforms map prepared by LGS and on maps of various scales to show detail in selected areas. In addition, text, diagrams, graphs and charts will be in the booklet accompanying the landform map. Included in the atlas will be maps and reports describing the geologic and structural framework of coastal Louisiana.
Geologists and cartographers from the LGS will participate in the project and experts from the LSU Department of Geology & Geophysics, Tulane, the University of Louisiana-Lafayette, University of New Orleans, two environmental consulting firms and the petroleum industry will author sections of the atlas.
A final draft of the atlas is scheduled to be available for review in late December 2018, with production planned for mid-2019.
