The content included in this institutional repository submission includes a series of Google Earth Engine code as well as supporting shapefiles for categorization of river classes as part of the work titled "Aquatic habitat changes along the Arkansas River, Arkansas USA". 
Individual files are described below and shapefiles contain associated metadata.

JRC Transition Classes Code (URL shortcut): this is a Google Earth Engine url link to code that quantifies change by pool in the Arkansas River (1984-2016) by transition classes in the Global Surface Water Explorer dataset.  
Note you must have a Google Earth Engine account to access the content of this link.

JRC Transition Classes Code.txt: Text file of Google Earth Engine code for JRC Transition Classes

JRC_Yearly_Seasonal_Permanent_Extent (URL shortcut): this is a Google Earth Engine url link to code that quantifies annual extent of seasonal and permanent surface water by pool in the Arkansas River (1984-2016) for the Global Surface Water Explorer dataset.  
Note you must have a Google Earth Engine account to access the content of this link.

JRC_Yearly_Seasonal_Permanent_Extent.txt: Text file of Google Earth Engine code for JRC Yearly Seasonal and Permanent surface water extents.

Shapefiles/ArkChan_hab_diss.shp: This is the file breaking down the Arkansas River channel by pool and dyke pool/off-main channel/main channel. It is only the channel from bank and permanently connected lakes.

Shapefiles/ArkChan1974_SR_wgs1984.shp: The Arkansas River channel divided by pool and habitat type (Main Channel, Off Main Channel, Dyke Field), in the Geographic WGS 1984 projection.

Shapefiles/ArkRiProjBuf6mi.shp: Single polygon that represents a 6 mile buffer from the Arkansas River main channel for the entire length of the Arkansas River system. Note this is considered the maximum boundary in the analysis and was used for visualization only.

Shapefiles/SR500m_river_access_Diss.shp: 500 m buffer of the extract from NHD Area merge of water bodies w/in six miles of the arkansas river and constrained by river access. Originally derived from National Hydrography Dataset. Results are split based on pool. This layer was used as the "study region" in anlysis (mask for global surface water change data).

Shapefiles/SRFEMA_habitat_merg.shp:FEMA floodplain surrounding the Arkansas River. Note this layer was derived based on FEMA flood frequency. In one area where the FEMA floodplain was not available, it was simulated using a cost-distance function from elevation
