Canadian National Railroad has contracted Mendrop to evaluate the hydrologic conditions and hydraulic characteristics of existing bridges and culverts in order to provide guidance for replacement.

The downstream migration of an upstream channel bend was jeopardizing the embankment of State Route 42 and Bridge No. 107.9 over the Chickasawhay River. The Mississippi Department of Transportation contracted Mendrop and two subconsultants, Tice Engineering, Inc., and Biedenharn Group, LLC, to conduct a hydraulic study of the river, provide a hydraulic design for stream stability and countermeasures, and develop final Right-of-Way plans for bank stabilization and countermeasures.

Significant rain in February of 2020 caused landslides along Redwood Road in Vicksburg, Mississippi, resulting in approximately 1,000 feet of damage. Mendrop was contracted to provide erosion control plans, hydraulic design analysis, and roadway design plans.
