Erosion and Sediment Control Tip #53

 

Retaining Walls are “Engineered” structures.  The design of a Retaining Wall is site-specific and must take into consideration both the soil forces and the hydrostatic forces that are constantly trying to overturn the wall.  Proper surface and internal drainage must also be provided.

Alabama Irrigation Initiative Making a Difference in the Wiregrass

Image
Barbour County Farmer Andy McRae shows off the difference between his irrigated and non-irrigated corn. The Alabama Irrigation Initiative, launched by the Alabama Soil and Water Conservation Committee (ALSWCC), aims to address the challenges posed by unpredictable weather patterns in the state of Alabama. The initiative focuses on increasing the percentage of irrigated farmland in the state by encouraging the adoption of water-saving irrigation systems and techniques. Some of these methods include drip irrigation, micro irrigation and center pivot irrigation. By using these water-efficient practices, farmers can optimize water use and reduce waste, making their agricultural practices more sustainable. The initiative started in 2019 in the Middle Tennessee River basin and expanded into the Choctawhatchee and Pea River (Choc-Pea) watersheds of southeastern Alabama in 2021. The Choc-Pea watershed has sandy clay soil with low water-holding capacity, making irrigation particularly benefici

Today’s Erosion and Sediment Control Tip: #16

  Today’s Erosion and Sediment Control Tip Sediment Basins require a device to dewater from the surface of the basin to remove the cleanest (less turbid) water.  This is often accomplished with a skimming device that is designed to remove the stored construction runoff over a period of 2 to 5 days.  It is important that the skimmer be installed and maintained properly. Skimmers must have a flexible connection to the rigid pipe or riser system that goes through the dam.  It should easily operate at all design elevations.  When placed on a principal spillway riser, the pipe from the skimmer to the flexible connection should be about 1.5 x the height of the riser structure. The flexible pipe outlet at the rigid pipe or riser system through the dam should be at the standing pool elevation to ensure the skimmer does not function below the required elevation. A rock pad should be constructed for the skimming device to rest on when discharge is complete.  The skimmer may need checking occasio

Erosion and Sediment Control Tip #54

  Although non-native grasses such as Pensacola Bahia, Bermuda and Tall Fescue are very important in our erosion control planting for vegetative cover, we professionals should be aware of other non-native plants (shrubs and trees) that could be considered highly invasive to our environment. Are the shrubs or trees being used on your jobsite considered to be invasive?  How many invasive plants can you see in this picture? There are at least four.   Find out more information on the Alabama Invasive Plants Council website. https://www.se-eppc.org/alabama/ _________________________________________________________________________    Use the following link to register or book a hotel room: https://alabamasoilandwater.gov/wp-content/uploads/2023/08/2023ClearWaterAla_Email.pdf   Perry L Oakes, PE Erosion and Sediment Control Program Coordinator AL Soil and Water Conservation Committee
