Soil aggregate stability typically have a higher water infiltration rate, allowing more water into the soil profile faster, and are not susceptible to water ponding. Soil aggregates are formed due to flocculation and cementation processes, and are enhanced by physical and biological processes. Primary soil particles (sand, silt, and clay) are subjected to these processes, and can stick together to form larger sub-microaggregates (< 250 μm), microaggregates, and macroaggregates (> 250 μm). It has been suggested that soil aggregates form hierarchically, meaning larger less dense aggregates are composed of smaller more dense aggregates (Kay, 1990; Oades, 1993). Flocculation refers to a state when
Godalming of the town centre steep hills reach 95 m (311.67 ft) AOD from 40-45m (131.23-147.63 ft) AOD in the town centre itself. In terms of rock and mineral structure, the soil is Gault Clay superimposed by Upper Greensand, Claygate Beds and Bagshot Sands; throughout the narrow east-west middle valley of Godalming and its wide northeast suburbs (Farncombe and Catteshall) the rocky head geological deposit is also found; angular pieces of rock and soil derived locally from the extensive frost-shattering of rocks and the subsequent movement of this material down valley slopes. Soil is mostly, i.e. on the upper slopes of
