The high load of suspended sediments in Kansas rivers and reservoirs has raised many concerns about the quality of the state's water supply. Erosion originating in pastures, croplands, gullies and channel-banks accounts for the majority of the suspended sediment load. Pasture and cropland adjacent to river and stream banks without riparian buffers increase de-stabilization allowing for bank deterioration and contribute non-point source pollutants such as fertilizers, pesticides and fecal matter. Determining high-risk areas along rivers and tributaries for either riparian remediation or bank stabilization is part of our research. Using GIS technology with present day and historical aerial images, high risk areas of the river channel [...]
