Description: The storage of relatively wet silage in a tower silo often causes the silage to become saturated. Silage juice is expelled and wall pressures increase substan tially. The magnitude of these increased wall pressures are not well known. This paper presents a procedure to simulate the consolidation of silage in a tower silo and the liquid flow in the saturated zone. The output from the simulation includes the saturation level in the silage, the fiber and liquid pressures and the total amount of silage juice effluent. The 30-d simulation of a full-scale test by 't Hart et al. (1980) shows that the procedure provides satisfactory results. A detailed compar ison of settled height of silage and of fiber and liquid pressures are presented. The results of the simulation show the importance of good silo drainage in reducing the liquid pressures in the saturated silage zone.
