Design Concepts For Vegetated Waterways - Historic Landmark of Agricultural Engineering Rainfall runoff causes severe gully erosion on unprotected lands and has ruined thousands of U S acres in the past. Concepts were developed at this site for vegetation-lined waterways that now safely convey runoff water from millions of acres.Engineers of the US Soil Conservation Service (SCS) initiated studies on hydraulics of vegetated waterways at an outdoor laboratory near Spartanburg, South Carolina, in 1935. Under the directions of W. O.

Since 1948, over 11,000 dams and associated conservation practices in more than 2,000 watershed projects encompassing 160 million acres in 47 states have been constructed as a part of the USDA Small Watershed Program. These projects have improved the quality of life and the environment in rural communities by protecting people's lives and property, conserving soil and water resources, reducing flooding, providing economic development, recreation, and water supplies, enhancing water quality, and improving wetlands and wildlife habitat.

Innovations

Aberdeen Range, Aberdeen Proving Ground

During the 1930's, research into advanced ballistic measurement techniques began at Aberdeen Proving Ground—the world's first large-scale, fully-instrumented ballistic range producing data on the aerodynamic characteristics of missiles in free flight.

Although this research had begun…
