Features of a Chevron Weir Rock Ramp
This paper presents the features of a new type of low profile grade control structure, the chevron weir rock ramp. As the name infers, the planform of the structure is in the shape of...

Rock Riprap for Grade Control
Rock chutes (riprap channels on steep slopes) are used as grade control structures to safely conduct a water flow to a lower elevation. Common procedures used for design of rock riprap...

Utilizing Geomorphic Analogs for Design of Natural Stream Channels
Engineering guidelines for the design of stable rock armored channels are well established. However, few guidelines exist for designers involved with the reconstruction of channels with...

Riprap and Concrete Armor to Prevent Pier Scour
Local scour is not a product of recent times or modern building practices. The annals of the Institute of Civil Engineers, in London, contain references throughout the 1800s and early...

Design of Guide Banks for Bridge Abutment Protection
As an alternate to designing bridge abutments to withstand the development of the full scour prism predicted by equations currently available for estimating abutment scour, FHWA recommends...

Measurements of the Hydrodynamic Lift and Drag Forces Acting on Riprap Side Slope
Direct measurements have been made of lift and drag forces acting on a 20.1 mm spherical particle placed within the riprapped 1.5 H: 1 V side slope of a 10 m long channel which was protected...

Sandstone Materials Used as Riprap
A study was conducted to determine if sandstone materials could be potentially used as riprap. Nineteen rock samples (16 sandstone samples) were collected in six western states. The rock...
