Abstract: Myxospermous seeds become bound by mucilage upon hydration and this trait greatly affected the soil properties. However, the capacity of myxospermous seeds to regulate the water flow in soil remains to be tested. In this paper, a mathematical model is developed to simulate the flow rates in sandy-loam soils that are amended by myxospermous seeds. The influence of the factors seedbank density and soil-seed layer depth were analysed in a series of parametric studies. The results showed that a soil seedbank density of 4 {6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} [w/w] myxospermous seeds applied uniformly across the soil layer and in conjunction with higher densities at the upper-most top surface of soil would have greatest capacity to reduce water flow rate.
