Permitted accumulated geocell deformation – below 2% (para. 1.2.4) “…Therefore, this type of base reinforcement is only effective if the deformations are limited to, for example, 0.5%. A distortion (elongation) of the geosynthetics of 2% horizontally will lead to many centimeters of distortion vertically in the road. 3. Geocell key ...

the spillway until meeting the constantly sloping portion of the spillway. The ogee shape is designed with steps that transition in size until the full step height is reached at the point of tangency with the spillway slope. The sloping flume flows into a 30-ft-long (9.14 m) tailbox to study the formation of the hydraulic jump.
