What Is Riprap? And Why It Rocks!

What is Riprap? Riprap describes a range of rocky material placed along shorelines, bridge foundations, steep slopes, and other shoreline structures to protect from scour and erosion. Rocks used range from 4 inches to over 2 feet. The size of the rock needed on a project depends on the steepness of the slope and how… Read More »

Benefits of 2D Modeling for River Hydraulics

By Dusty Robinson, PE Two-dimensional (2D) hydraulic models are not new to the industry; they’ve been in use for close to 30 years. However, older 2D models required highly experienced users and the technology was expensive and cumbersome so they were typically only used on complex projects. Recently, advances in computer technology and 2D modeling… Read More »

FHWA Publishes Reference for 2D Hydraulic Modelers

By Dusty Robinson, PE In recent years the popularity of 2D hydraulic modeling has grown, thanks in part to the fact that newer versions are easier to use and are helping modelers better communicate complex hydraulic concepts of real-world river systems. About the Expert: Dusty Robinson, PE, is a water resources engineer in Ayres’ Fort… Read More »
