The major processes involved are precipitation, evaporation, interception, transpiration, infiltration, percolation, retention, detention, overland flow, throughflow, and runoff.

The bare zones (‘intergroves’) act as runoff sources and overland flow moves downslope where infiltration of runon water takes place in vegetated patches (‘groves’) that show higher soil infiltrability. In many cases the soil surface in the runoff source areas is colonised by cyanobacteria and bryophytes.

Overland flow is calculated as a series of time steps traveling downhill over an elevation surface. Figure 1 shows the overland flow from a simulated spill. It is a conservative estimate as the simulation assumes sheet/flat flow at minimal inclinations, no soil infiltration and an unlimited quantity of liquid.

Another mechanism that contributes to the delivery of "old" water to a stream under storm conditions is the entrainment of "old" soil water by overland flow. Overland flow in riparian areas occurs in patches, with surface water flowing into the soil, mixing with shallow soil water, and then reemerging on …
