gbam,
there has not been any other study done, than by map analysis, transit for gradient, and visual observations and calculations for water flow.
I have contacted MacCaferri. They are looking into it now.
gbam,
thanks for the help...
The river shown in the attached section is depicted at maximum expected 1000yr flood stage (4" rain/hr.), dashed line at Agatha level (1.7"/hr). The typical river level meanders in the river basin at 200cfs in the dry season to 1-4000 cfs between storms in the...
The project is the construction of a river wall extending approx. 1.6 miles down both sides of a 75 meter wide channel. We plan on using 7 levels of 2x4 meter gabions, as shown in the attached files. 3 levels below the river bed and 4 above. During the rainy season, the river basin gains 1-2.5...
If one were to put a skin coat of 2" of concrete w/ 1/4" expansion joints on 18" centers on the top face of the mattress surface, would that eliminate the majority of the shear and raise the capability to carry much higher fluid velocities?.
(for calculations sake)In a river with a calculated flow of say 30fps, does the liquid have the same velocities at the gabion boundary layer as the rest of the river or is it reduced?
I am working with the native population in Panajachel, Guatemala. I am trying to design a river containment system (dikes) with 30º bank slope, covered with 9" x 2m x 4m gabions o/geotec fabric. The river gradient is 200'/mile, the width 70m, x 2m max depth (20,775 cfs)for max (1) 12hr period...
