North Platte River-South Platte River Confluence Area Drainage System History as Determined by Topographic Map Interpretation: Western Nebraska, USA

Progressive abandonment and planform changes ofthe central Platte River in Nebraska, central USA,over historical timeframes

This paper presents data compiled from aerial photography, General Land Office maps (GLOs), and discharge data from the central Platte River in Nebraska that quantify and provide a new understanding of channel evolution and abandonment in a braided stream. Analyses of aerial photographs and GLOs in ArcMapTM show that channel area decreased by an average of 46% from 1938 to 2006 and that channel...

Protecting Public Values in the Platte River

Net recharge vs. depth to groundwater relationship in the Platte River Valley of Nebraska, United States.

One-km resolution MODIS-based mean annual evapotranspiration (ET) estimates in combination with PRISM precipitation rates were correlated with depth to groundwater (d) values in the wide alluvial valley of the Platte River in Nebraska for obtaining a net recharge (Rn) vs. d relationship. MODIS cells with irrigation were excluded, yielding a mixture of predominantly range, pasture, grass, and ri...

Association Between Local Land Use and Herbicide Concentrations in Wetlands of the Platte River Basin, Nebraska

Association between local land use and concentrations of selected herbicides in wetlands was examined at 31 sites in Nebraska. Sites were selected based on water depth, surface area, and the management of sites as wildlife habitat. In May and August 1994, water-column samples were collected at each of the sites and were analyzed for selected herbicides. The wetlands were categorized into three ...
