Best Practices for Dealing with Temperature Fluctuations include:

• 50-degree temperature swings can cause  significant changes in GM dimensions  
• never backfill anchor trench until GM has experienced two or three days of temperature cycles
• install wrinkle across the toe on short slopes and then cut it out if needed on long slopes, place wrinkle further upslope because wrinkle will not move upslope
• fill containment with water or other material to stabilize GM as soon as possible
• include 3 to 3.5% extra unreinforced GM material (slack) for thermal contraction when large temperature fluctuations are anticipated
• calculate the wrinkle height using the equation from Giroud and Wallace (2016) so the coefficient of thermal expansion for each GM type, interface friction angle, e.g., smooth v. textured, bending modulus, and material type, are important parameters in the calculation
