# For the settlement calculation with the RF-SOILIN add-on module, the weight gamma and the specific gravity gamma, sat are interrogated for a certain soil. What do I need the value gamma, sat for, and how does it fit into the calculation?

The value $\gamma,_{sat}$ corresponds to the weight of the saturated soil and can be adjusted, if necessary, in the material parameter settings. If there is groundwater in a layer, the weight of the saturated soil $\gamma,_{sat}$ is automatically reduced from this layer by the weight of groundwater (10kN/m³). Above this layer, the stresses are calculated with the specific weight of the soil.
