Bradley Uses GeoCoPS Software to Develop Design Criteria
GeoCoPS is an interactive program for the design of geosynthetic tubes. For a given problem, the geometry of the tube and the circumferential and longitudinal required strength of the encapsulating geosynthetic are produced. The computations account for reduction factors related to seam strength, durability, creep and installation damage. Results are obtained by solving a differential equation subjected to design constraints. The user, however, is not directly involved with the calculations thus no knowledge of differential calculus is needed... GeoCoPS can also provide the consolidated shape of the tube in an approximated manner. This may be important for assessing storage capacity or for construction of structures such as levees.
Version 1.0 of GeoCoPS was developed for the US Army Corps of Engineers in 1995. The current version (2.0) is an outgrowth of the original version. It is based on the report entitled Geosynthetic Confined Pressurized Slurry (GeoCoPS): Supplemental Notes for Version 1.0, by Dov Leshchinsky and Ora Leshchinsky, Technical Report CPAR-GL-96-1, September 1996, US Army Corps of Engineers, Waterways Experiment Station. Version 2.0 has both computational and functional enhancements compared with version 1.0.

The Golden Section is a ratio based on a phi.
The Golden Section is also known as the Golden Mean, Golden Ratio and Divine Proportion. It is a ratio or proportion defined by the number phi = (1.618033988749895).
The ratio of the whole line (A) to the large segment (B) is the same as the ratio of the large segment (B) to the small segment (C). In other words, A is to B as B is to C.
This occurs only where: A is 1.618 times B and B is 1.618 times C.
This ratio has been used by mankind for centuries. Its use started as early as with the Egyptians in the design of the Pyramids.

The SPIRAL geotube is designed using the Golden Ratio. The Golden Ratio is used today in the design of SPIRAL geotubes.
H = Height of structure (given)
A = Circumference
B = Distance from one side of footprint to the other
