Slope Stabilizing TRM Design - Full Design

I need a practical, fully-worked design example for a Turf Reinforcement Mat whose primary job is slope stabilization. The concept must use a hybrid construction—part synthetic, part biodegradable—to capture the durability of geosynthetics while allowing vegetation to take over as the natural layer forms. High tensile strength is the critical performance parameter; UV resistance or total biodegradability can be noted only where they directly affect the structural calculations.

Here is what I expect to receive:
• A concise design narrative explaining the chosen material blend, expected service life, and how the mat transitions load to the subgrade.
• Calculations (factor of safety against sliding, pull-out resistance, anchoring pattern, and any hydraulic/shear checks) presented in a clear spreadsheet or PDF so I can follow each step.
• A scaled cross-section drawing that shows the mat, soil layers, anchoring system, and vegetative cover. CAD (DWG) or high-resolution image formats are both fine.
• A brief installation guideline highlighting anchor spacing, seeding recommendations, and inspection points.

I will review the submission against these criteria: accuracy of calculations, clarity of the drawing, and how well the material selection meets the high-tensile requirement while blending synthetic and biodegradable components.
