Description	CADA (Consolidation And Desiccation Analysis) models a new rational desiccation theory for the overall consolidation and desiccation process of soft fine soils using a nonlinear finite element method. The software models different densification methods such as: self-weight consolidation, seepage consolidation due to bottom or intermediate drainage layers, lowering ground water level, surface drying under surface evaporation, and surface loading. There are three versions of the program: CADA1: For the one-dimensional simulation of the overall consolidation-desiccation process. The analysis assumes no creation of desiccation cracks. It predicts the soil layer settlements with time, and profiles of void ratio and pore water pressure (and suction) along the current soil layer height, and the boundary water velocities at various times. CADA2: As CADA1 but also simulates three-dimensional shrinkage. It predicts the progress of volume and depth of desiccation cracks with time. CADA3: It simulates the overall consolidation-desiccation process during the slurry deposition and the presence of any number of intermediate drainage layers. It requires information on the slurry deposition rates and location of any intermediate drainage layers. CADA1 and CADA2 are commercially available; CADA3 is under development, but is available from the author. Manual available on WWW.
