Abstract

The purpose of this study was to evaluate the hydraulic characteristics of runoff flows in furrows by electronic measurements of runoff velocities and establishment of water surface elevations at various stations in the furrows.Specifically this included:

1. Improvement of previously developed equipment and techniques, or development of new devices and techniques.

2. Conduct field trails and collect data.

3. Compare results with the equation Q = AV, where Q is the runoff rate, A is the cross-sectional area of the runoff stream, and V is the velocity of the stream.

The specific measurements needed to study the hydraulic characteristics of the furrows were, the water surface elevation, the velocity of the runoff, the runoff rate, the shape of the furrow cross-section and the furrow slope.The measurement of the water surface elevation was the most critical to this study.
