The variation in moisture content between subsequent irrigations determines the use of infiltration equations that contain representative physical parameters soil when irrigation begins. This study analyzes reliability hydrodynamic model to simulate advanced phase border irrigation. For solution model, a Lagrangian scheme implicit finite differences is used, while for infiltration, Kostiakov eq...

infiltration is a complex process that changed by initial moisture and water head on the soil surface. the main objective of this study was to estimate the coefficients of infiltration equations, kostiakov-lewis, philip and horton, and evaluate the sensitivity of these equations and their coefficients under various initial conditions (initial moisture soil) and boundary (water head on soil surf...

Abstract In China, fresh water resources are scarce, while brackish abundant. Reasonable utilization of is one the important measures to alleviate contradiction shortage. order study effect irrigation on and salt transport in saline-alkali soils, one-dimensional infiltration experiments soil columns were conducted. The influence with different salinities salinized was compared analyzed. results...

This research examined the types and characteristics of soil, including porosity, water content, void ratio, degree saturation to value infiltration rate in soil located western part Semarang City, Indonesia. The test was carried out at 49 measurement points, based on a 2×2 km 2 grid division area. field using turf-tech infiltrometer. data from results were calculated estimation model Kostiakov...

Aeolian sandy soil in mining areas exhibits intense evaporation and poor water retention capacity. This study was designed to find a suitable biochar application method improve infiltration minimize for aeolian sand soil. Using the indoor column method, we studied effects of three patterns (A (0–20 cm mixed sample mixed-based soil), B (0–10 10–20 C soil)), four amounts (0% (control, CK), 1%, 2%...

This report consisted of studying the effects caused by soil physical characteristic, in presence wetness variations and structures-texture fluctuations, to Kostiakov constants. The objectives were investigate wetness, depth, compaction on constants “a”, “b”. experimental unit nine polyvinyl cylinders. Statistical analysis under a randomized block design with three replications factors: five le...
