This content represents a compressed folder of the processed datasets for the waterborne resistivity profiling surveys of streams in the Mississippi Alluvial Plain. This file bundle contains 8 .csv tables, each representing raw data for an individual stream.

Digital flood-inundation maps were created by the U.S. Geological Survey (USGS) in cooperation with the Muskingum Watershed Conservancy District and the City of Rittman as part of a Federal Emergency Management Agency (FEMA) Flood Insurance Study (FIS). The flood-inundation maps show estimates of the areal extent corresponding to the 1% and 0.2% annual-exceedance probability floods. Flood profiles were computed for each stream reach by means of a one-dimensional step-backwater model.

Digital flood-inundation maps for an 18.6-mile (mi) reach of the Clear Fork Mohican River (that extends approximately from 100 feet upstream from Gass Road near Lexington, Ohio to 700 feet downstream from Benedict Road in Butler , Ohio) and for a 5.9-mile (mi) reach of Cedar Fork (that extends from its confluence with Clear Fork Mohican River to Wirick Road/Richland County Line) were created by the U.S. Geological Survey (USGS) in cooperation with the Muskingum Watershed Conservancy District as part of a Federal Emergency Management Agency (FEMA) Flood Insurance Study (FIS). The flood-inundation maps show estimates of the areal extent corresponding to the 1% and 0.2% annual-exceedance probability floods. Flood profiles...
This data release consists of two .csv files of inverted models of electrical resistivity created from the processed resistivity data in the accompanying two data releases: (Miller and Others, 2018) and (2018 Raw and Processed, in progress). During 2016, 17, and 18, the U.S. Geological Survey conducted continuous resistivity profiling along 15 rivers or lakes in the Mississippi Alluvial Plain of Mississippi, Arkansas, Louisiana, and Missouri to characterize streambed hydraulic conductivity values. These techniques characterize the near surface geomorphology of the streambed that controls the recharge to the alluvial aquifer. These data can be used to map changes in the lithology of the streambed and identify areas...

This content represents a map displaying the vector data corresponding to the processed datasets for the waterborne resistivity profiling surveys of streams in the Mississippi Alluvial Plain. The .sd file is an ESRI service definition file containing all the data (capatible for use in ESRI ArcDesktop). This file bundle contains 8 shapefiles, each representing an individual stream. These are all displayed in the map service definition. Users can also download the .sd file and extract the content (using 7zip, winzip, etc.) on their local machine to obtain all the stand-alone shapefiles.

Digital flood-inundation maps for an 18.6-mile (mi) reach of the Clear Fork Mohican River that extends approximately from 100 feet upstream from Gass Road near Lexington, Ohio to 700 feet downstream from Benedict Road in Butler , Ohio, were created by the U.S. Geological Survey (USGS) in cooperation with the Muskingum Watershed Conservancy District as part of a Federal Emergency Management Agency (FEMA) Flood Insurance Study (FIS). The flood-inundation maps show estimates of the areal extent corresponding to the 1% and 0.2% annual-exceedance probability floods. Flood profiles were computed for the stream reach by means of the one-dimensional step-backwater model HEC–RAS. The model was calibrated by using the current...

This data release has three components for each of the eight stream lengths: 1) a geospatial dataset of the processed data; 2) tabular data of the processed waterborne resistivity profiling data and associated water-quality data; 3) tabular data of the raw waterborne resistivity data and associated water-quality data. In fresh water aquifers, the geoelectric resistivity of earth materials commonly has a positive correlation with hydraulic conductivity (Faye and Smith, 1994). Throughout 2017, continuous resistivity profiling data were collected, as a proxy for streambed hydraulic conductivity, along reaches of eight streams in the Mississippi Alluvial Plain of Mississippi, Arkansas, and Missouri. A total of...
