Wave Erosion Measurements for an Irrigation Reservoir Embankment

Erosion Wave Irrigation Reservoir

United States Department of Agriculture (USDA) Agricultural Research Service (ARS)

Titre : Wave Erosion Measurements for an Irrigation Reservoir Embankment

Identification : 6060-13000-026-063-S

Pays : Etats Unis

Durée : Start Date : Aug 31, 2021 // End Date : Aug 30, 2026

Location : Watershed Physical Processes Research Oxford MS

Objectifs
The main goal of the work is to measure erosion of an earthen embankment in an irrigation reservoir with different forms of protection : no protection, geotextiles, and floating wave barriers. A secondary goal is to improve methods for quantifying bank retreat using photogrammetric methods.

Approche
We have an established research site at an irrigation reservoir near Shelby, Mississippi, with a weather station and wave gauges. We will continue the project by measuring bank retreat and erosion to quantify differences in erosion for levee sections protected by geotextiles and floating wave barriers. The land manager plans to rebuild the levee system in 2021-2022, which will give us an opportunity to make erosion measurements on levee slopes that have not already been degraded by erosion.
