Abstract

Introduction Soil infiltration rate is the major soil hydraulic property which can be affected by the soil physical characteristics and management practices. The use of land can affect various soil properties such as physical and hydraulic properties. Differences of the hydraulic soil characteristics such as infiltration rate in various land uses can affect their potential to runoff production as well as soil loss in the catchment. The knowledge of the physical and hydraulic characteristics of various land uses can help to better management of soil and water in the catchment. It is very essential in the semi-arid catchments where VEGETATION COVER is generally poor, the soils are often instable against erosive factors especially when the rainfalls are consecutive and intensive. Therefore, this study was conducted to investigate the soil physical and hydraulic characteristics in the TahamChai catchment, in a semi-arid region, NW Zanjan. Various land uses consist of PASTUREs, rainfed and IRRIGATED LANDs can be observed in the catchment, which cover about 62%, 33%, and 5% of the catchment area, respectively. The PASTUREs have been covered with poor vegetation and are intensively exhausted by overgrazing. RAINFED LANDs are mostly under winter wheat cultivation. Soil erosion and sedimentation were the major environmental problem in this catchment.Materials and Methods The maps of land use and slope gradient were provided for study area. A total of 20 sites were selected based on the surface area of each land use in the catchment located between 34° 46’-36° 53¢N latitudes and 48° 17’-48° 37’ E longitudes. The study area consisted of ten sites in the PASTURE, seven sites in the rainfed and three sites in the IRRIGATED LANDs. The geographical positions of study sites were determined by a global positing system (GPS).
