Peat soil has unique hydraulic characteristics that affect water movement, infiltration, and storage. Understanding its hydraulic conductivity is essential for effective peatland restoration and sustainable water management. This study compares the hydraulic conductivity values obtained from field and laboratory measurements in the Tanjung Leban Landscape, Bengkalis, Indonesia. Field data were collected using the Slug Test method, while laboratory tests used the Falling Head method on the same peat samples. Results show that the Slug Test produced higher conductivity values, ranging from 0.011 to 0.741 m/day, whereas the Falling Head test yielded lower values between 2.57 × 10⁻⁸ and 1.33 × 10⁻⁷ m/s. The difference reflects natural macro-pores and root channels influencing field flow, while laboratory conditions represent intrinsic permeability. These findings indicate that field measurements describe effective hydraulic conductivity, whereas laboratory tests capture intrinsic hydraulic behavior, offering valuable insights for peatland hydrological modeling and water management.
