        abstract = {Infiltration is a critical component of the hydrological cycle that regulates the movement of water from the land surface into the subsurface, thereby influencing surface runoff, soil moisture dynamics, and groundwater recharge. It is governed by multiple factors such as soil texture, antecedent moisture conditions, permeability, land use, and rainfall characteristics. In this context, infiltration tests were conducted in eight villages of Chikkaballapura Taluk under the National Aquifer Mapping Program 2.0 of Central Ground Water Board during 2025–26 to assess spatial and seasonal variability in infiltration behavior.
Field infiltration tests were conducted during the monsoon (September 2025) and repeated the tests on the same location in non-monsoon (February 2026) seasons revealed a wide range of infiltration rates varying from 0.4 to 52.8 cm/hr in monsoon and 1.2 to 64.8 cm/hr in non-monsoon season. Clayey soils exhibited very low infiltration rate of 0.4 cm/hr in monsoon and 1.2 cm/hr in non-monsoon season reflecting their compact structure and low permeability rates, whereas sandy clay soils showed significantly higher infiltration rates of 52.8 and 64.8 cm/hr owing to their coarse texture and greater porosity. Moderate infiltration rates of 6 to 8.4 cm/hr and 1.6 to 2.4 cm/hr in monsoon and non-monsoon season were recorded in clay mixed soil types. Seasonal analysis indicated that infiltration rates are relatively lower during the monsoon season due to higher antecedent soil moisture, while higher initial infiltration rates were recorded during the non-monsoon season under dry soil conditions.
The analysis of cumulative infiltration and infiltration rate versus time curves demonstrated distinct seasonal patterns, with rapid stabilization of infiltration rates during monsoon and gradual decline during non-monsoon. The study highlights that soil texture is the dominant factor controlling infiltration characteristics, while seasonal moisture conditions play a secondary role. The findings provide valuable insights for groundwater recharge planning, watershed management, and sustainable water resource development in the study area.},
