Richard J Huizinga, P.E.
Richard (Rick) Huizinga is interested in applying concepts of hydrodynamics and geomorphology to help solve real-world problems such as erosion hazards (scour) near bridges and erosion and deposition in rivers and lakes.
Rick is a project hydrologist at the Central Midwest Water Science Center in Rolla, Missouri. Rick received his bachelor’s degree and master’s degree in civil engineering (focused on Hydrology and Hydraulics) from the Missouri University of Science and Technology (M S&T, formerly UMR). Since joining the USGS in 1991, Rick has devoted his career to studying surface water hydraulics and specializes in bridge scour and applications of multibeam echosounders and motion-compensated and tripod-based lidar technology for geomorphic assessment and change detection. He has participated in applied research focusing on predicting and measuring scour at bridge piers using hydraulic models and field methods. Rick is a recognized expert in the use of multibeam echosounder technology for assessment of bridge scour during floods as well as bathymetric surveying of inland alluvial rivers and streams and lakes.

Use of High-Resolution Topo-Bathymetry to Assess Shoreline Topography and Future Development of a Slackwater Harbor near Dardanelle, Arkansas, October 2021
The U.S. Army Corps of Engineers - Little Rock District (SWL) Civil Works program has a mission to maintain cohesion between physical and naturally developed environments. Evaluation of shoreline stability and adjacent development of a harbor along the McClellan-Kerr Arkansas River Navigation System at River Mile 202.6 is essential in establishing a baseline for potential impacts and future monit
Bathymetric and supporting data for various water supply lakes in northwestern Missouri, 2019 and 2020
Water supply lakes are the primary source of water for many communities in northern and western Missouri. Therefore, accurate and up-to-date estimates of lake capacity are important for managing and predicting adequate water supply. Many of the water supply lakes in Missouri were previously surveyed by the U.S. Geological Survey in the early 2000s (Richards, 2013) and in 2013 (Huizinga, 2014); ho

Hydrographic surveys of rivers and lakes using a multibeam echosounder mapping system
A multibeam echosounder is a type of sound navigation and ranging device that uses sound waves to “see” through even murky waters. Unlike a single beam echosounder (also known as a depth sounder or fathometer) that releases a single sound pulse in a single, narrow beam and “listens” for the return echo, a multibeam system emits a multidirectional radial beam to obtain information within a fan-shap
