Corps continues flows from Lake O, supports firefighting in Everglades National Park

The U.S. Army Corps of Engineers Jacksonville District will continue flows from the W.P. Franklin Lock and Dam (S-79) to the Caloosahatchee estuary at a 7-day average rate of 457 cubic feet per second (cfs). Flows to the St. Lucie estuary remain at zero cfs as measured at the St. Lucie Lock and Dam (S-80). Releases are made in a pulse pattern which begin on Saturday. In addition, our partners at the South Florida Water Management District have coordinated with the Corps as they mobilize pumps and modify water management operations to help control a wildfire in Everglades National Park.

Houston Ship Channel Expansion Reaches Major Milestone

GALVESTON, Texas – Yesterday, Galveston District of the U.S. Army Corps of Engineers (USACE) received a signed Chief of Engineers Report (Chief’s Report) for the proposed Houston Ship Channel Expansion Project. Signed April 23 by Lt. Gen. Todd T. Semonite, USACE Chief of Engineers and Commanding General, the report culminates a four-year, $10 million study conducted by USACE in partnership with Port Houston to identify needed channel improvements, determine economic value to the nation, and complete necessary environmental requirements. The signed report recommends adoption of the plan presented by Galveston District in order to support economic efficiency of commercial navigation throughout the Houston Ship Channel System.

PUBLICATION NOTICE: A Comparison of GenCade,  Pelnard-Considere, and LITPACK

PURPOSE: The purpose of this Coastal and Hydraulics Engineering Technical Note (CHETN) is to investigate the basic physics and numerical code of GenCade by running a series of simplified test cases and comparing the results to another numerical shoreline evolution model and an analytical solution. The complementary numerical code is the widely used shoreline evolution model LITPACK. The analytical model is the original solution derived by Pelnard-Considere (1956). The underlying assumption in all three approaches is a beach profile of constant shape so that shoreline change is driven by long-shore transport processes and a combination of independent sediment sources or sinks (e.g., sea level change, subsidence). The CHETN presents a descriptive overview of the theory behind the models followed by an inter-comparison using a set of four test cases involving shoreline change in the vicinity of idealized coastal structures and a beach nourishment. GenCade shows good agreement with LITPACK, and both models compare well to the analytical solution for these idealized cases. The GenCade results indicate that the underlying numerical code and basic physical process are consistent with other widely used shoreline modeling systems.
