Title:

ABFS - Extent of inundation based on Butte La Rose gage (Multidimensional) [U.S. Fish and Wildlife Service]

Description:

This multidimensional dataset depicts the probability of inundation in the Atchafalaya Basin Floodway System (ABFS) at increasing Atchafalaya River stages. The analysis used 28 Landsat images (1984-2008) classified into categories of wet (vs dry). Each pixel value was evaluated using a probit analysis (in R) to determine the probability that each pixel would be classified as wet or dry at a series of 1/2 foot increments from 1.6 to 21.6 feet based on theButte La Rose gaging stationfor a total of 41 distinct river stages. Methodologies for this classification are available in Allen et al. (2008) and Allen (2016).The dataset presented here is a multidimensional dataset with 41 bands corresponding to 41 river levels based on the Butte La Rose gaging station. Currently the bands reflect increasing river stages in 1/2 foot increments from 1.6 to 21.6 feet. Enable the multidimensional tool on the right side of the webmap to interact with the data. The Atchafalaya Basin is a resource that must be managed on a system-wide basis to ensure this invaluable national resource is protected and restored. It is recognized that better tools must be developed for managing the Basin and that data evaluation is necessary to ensure sound decision-making. The natural resource inventory and assessment system (NRIAS) that was approved and funded in the FY 2010 Louisiana Department of Natural Resources Atchafalaya Basin Program Annual Plan and served as the primary tool for decision making in the Basin. The system provided a means for scientists to access relevant project data for the Basin and to request and fund data acquisition, monitoring, and data analysis to be used in project planning. This will be critical in providing information necessary for the development and approval of specific projects to be included for construction in future Annual Plans, projects that meet the needs of Louisiana citizens and protect our our natural resources. This and related datasets were created to demonstrate the patterns of inundation, turbid water and floating aquatic vegetation in the Atchafalaya Basin Floodway System at various river levels of the Atchafalaya River.Allen, Y.C., Constant, G.C., and Couvillion, B.R., 2008, Preliminary classification of water areas within the Atchafalaya Basin Floodway System by using Landsat imagery: U.S. Geological Survey Open-File Report 2008 1320, 14 p. https://pubs.er.usgs.gov/usgspubs/ofr/ofr20081320Allen, Y.C.
