Over the years, cultivation using sustainable tillage practices has gained significant importance, but impact of on soil water infiltration is still a concern for landowners due to possible effects crop yield. This study investigates different managements rate sandy clay loam under semiarid environment. Field experiments were conducted in Chott Mariem Sousse, Tunisia. The consisted three treatm...

the parameters of infiltration equations have a key role to evaluate and design irrigation systems and it is essential to estimate them with high accuracy for increasing irrigation efficiency. in the present study, two approaches consisting multilevel optimization method using advance, recession and runoff data and the iparm model using advance and runoff data were compared for estimating infil...

Abstract Knowledge of soil infiltration characteristics is required increasingly for the proper design and efficient management irrigation. Various empirical physically based models have been used several years, but practical use many limited by parameter determination problems, which, in turn, are influenced factors acting at surface within soil, initial boundary conditions, etc. In this study...

Vertisol soils, which cover large lands in irrigated areas Turkey and the world, swell when wet form deep cracks dry. These properties of soils cause a significant decrease irrigation efficiency irrigating with surface methods, thus causing water insufficiency drainage problems. If appropriate time, flow rate furrow-border lengths are used, application can be increased these soils. For this pur...

introduction: the infiltration process is one of the most important components of the hydrologic cycle. quantifying the infiltration water into soil is of great importance in watershed management. prediction of flooding, erosion and pollutant transport all depends on the rate of runoff which is directly affected by the rate of infiltration. quantification of infiltration water into soil is also...
