英文摘要
Mulching of agricultural fields and gardens with pebbles has long been practiced to conserve soil
moisture in some semi-arid regions with low precipitation. Rainfall interception by the pebble mulch
itself is an important part of the computation of the water balance for the pebble mulched fields and
gardens. The mean equivalent diameter (MED) was used to characterize the pebble size. The maximum
static rainfall retention in pebble mulch is based on the water penetrating into the pores of pebbles, the
water adhering to the outside surfaces of pebbles and the water held between pebbles of the
mulch. Equations describing the water penetrating into the pores of pebbles and the water adhering to
the outside surface of pebbles are constructed based on the physical properties of water and the pebble
characteristics. The model for the water between pebbles of the mulch is based on the basic equation to
calculate the water bridge volume and the basic coordination number model. A method to calculate the
maximum static rainfall retention in the pebble mulch is presented. Laboratory rain simulation experiments
were performed to test the model with measured data. Paired sample t-tests showed no significant
differences between the values calculated with the method and the measured data. The model is ready
for testing on field mulches.
