Design Calculators - Landfill Gas (LFG) Pressure Relief Layer

• Required LFG Layer Transmissivity: Find the required LFG Layer Transmissivity and the corresponding hydraulic transmissivity.
  
  
• Gas Transmissivity to Hydraulic Transmissivity Conversion: Find the hydraulic transmissivity from a known LFG transmissivity.
  
  
• Gas Pressure Relief Layer Under Surface Impoundments: Find the transmissivity of a geocomposite layer required to release pressure built up due to gas entrapment.
