Hillslopes with soils having these horizons are expected to have low surface runoff.
In this study, the 'Lg' value of the basin is 0.462 km (Table 1), which shows low surface runoff in area.
Higher slope means high runoff which allows less residence time for rainwater; whereas, gentler slope means low surface runoff, which in turn allows more time for the rainwater to percolate and hence comparatively more infiltration (Sarkar et al. 2001).
In the low slope area the surface runoff is low allowing more time for infiltration of rainwater, while high slope area enhances high runoff with short residence time for infiltration and recharge.
The hydrophobicity leads to very low infiltration, thus generating surface runoff even at low rainfall intensities.
Silty soils, on the other hand, exhibit the least resistance to erosion because their permeability is low (resulting in more surface runoff), and their particle size is neither small enough to promote cohesion nor large enough to prevent entrainment.
Even low rainfall intensities generate surface runoff.
Despite the high precipitation in October 1984 (143 mm), erosion in the field area was low due to minimal surface runoff and consequently minimal hydraulic erosion.
In Amman, the chronic water shortage is mostly due to its geography: a high-elevation desert city with very little surface runoff, low rainfall, and a booming population.
For grass cover and litter cover plots, rainfall events of rainfall regime IV which had the longest duration, greatest depth and lowest intensity had the highest surface runoff coefficient, soil erosion amount and subsurface flow rate.
