Vegetation and water classifications for a segment of the Paria River upstream of the Colorado River Confluence, Arizona, USA

These data represent total vegetation and surface water along approximately 12 kilometers of the Paria River upstream from the confluence of the Colorado River at Lees Ferry, Arizona. They are derived from airborne, multispectral imagery obtained in late May 2009, 2013, and 2021, collected with a push-broom sensor with 4 spectral bands depicting Blue, Green, Red and Near-Infrared wavelengths at a spatial resolution of 20 centimeters. The vegetation classification data were created using a supervised classification algorithm provided by Harris Geospatial in ENVI version 5.6.3 (Exelis Visual Information Solutions, Boulder, Colorado). The water data were created using a Green Normalized Difference Vegetation Index...

Report: Souris River Watershed Wetland Inventory and Change Detection: Estimating the effects of wetland distribution and loss on water quality and quantity in a large prairie watershed

The impact of agricultural drainage and resulting non-point source nutrient export on water quality is a growing concern across the entire Prairie Pothole Region. In Canada, the three Prairie Provinces (Alberta, Manitoba, and Saskatchewan) are currently revising and reviewing surface water management strategies and have recognized the need for wetland restoration and conservation to help maintain and restore water quality, and sustain watershed health. However, unlike the US portion of the PPR, there is no complete wetland inventory for the Canadian portion of the PPR. As a result it is not currently possible to target wetland conservation and restoration efforts to maximize water quality benefits. This project...

Classified land cover and vegetation canopy cover data for an aeolian dune field near Lees Ferry, AZ

These data were compiled for assessing how geomorphic changes measured as topographic differences from repeat surveys represent measured and modelled estimates of aeolian sediment transport and dune mobility. Objective(s) of our study were to investigate whether topographic changes can serve as a proxy for aeolian transport and sediment mobility in dunefield environments. This was accomplished by relating topographic changes to modeled and observed estimates of sediment transport and dune mobility over months to decades within a partially vegetated dunefield starved of upwind sediment supplies. We specifically tested if topographic changes measured as net and total volume changes and topographic surface roughness...
