Several attempts have been made to increase the permeable area in the cities, which include the building of green facilities such as parks and urban forests. Since these areas were built with soil compaction, the potential for infiltrating water differs compared with the natural green area. Therefore, this research aims to analyze the influence of soil conditioning on the constant infiltration rate using variables such as soil compaction, texture, and the presence of vegetation cover in urban facilities. The data used were obtained through field infiltration measurement using a single ring infiltrometer. In this research, the analysis carried out includes soil texture, Horton equation, the difference between conditioned soils and control plots, and USDA hydrologic soil classifications. The results showed that all variables (soil compaction, the presence of vegetation cover, and soil texture) have a significant effect on the constant infiltration rate. Based on the soil conditioning, the infiltration rate is increased on the vegetated plots and decreased on the plots with the combination of vegetation and compaction, as well as the compacted plots. Furthermore, the effect of vegetation cover is more significant in silt loam textured soil, while the influence of compaction is more on clay textured soil. The potential constant infiltration rate on the plots of similar characteristics with green urban areas are on K2 and L2 with 2.698 mm/h and 1.525 mm/h, respectively. Therefore, these plots have a moderate runoff potential based on USDA hydrologic soil classification.

“…The infiltration occurs due to the clear and combined effect of the gravity and tension forces and the simple effect of the head of water above the soil surface. The infiltration process is affected by numerous factors, most notably the soil properties (texture, structure, and bulk density), its initial moisture, the condition of its surface, the rate of water application, physical and chemical properties of water, the temperature of the soil and water, and the condition of the soil profile (homogeneous or stratified) [1,2]. Soil water dynamics play a significant role in the hydrological cycle [3,4].…”

The optimal design of various irrigation systems requires knowledge and a deep understanding of various soil properties. Water infiltration in the soil is among the most prominent of these characteristics. Ten laboratory experiments were conducted to study the effect of the bulk density of stratified soils (two-layered soils), Where sandy loam soil, and clay soil were used. Three bulk density values were adopted for each soil, and experiments were conducted in different sequences. New empirical relationships were derived to calculate the cumulative infiltration depth and the depth of the wetting front in terms of time and the basic infiltration rate of the soil. The results revealed a high agreement between the values measured in the laboratory and those estimated from the proposed empirical equations for infiltration and wetting front depths with a coefficient of determination of 0.96 and 0.98, respectively. The results showed that the infiltration and wetting front depths increased with the cumulative infiltration time and the soil bulk density reduction, regardless of the soil location in the upper or lower layer within the stratified soil. It was also found that the infiltration rate was affected by the density of the upper stratum more than its influence by the change in the density of the lower stratum.
