Sensitivity Analysis and Validation for Numerical Simulation of Water Infiltration into Unsaturated Soil
A FORTRAN code for liquid water flow in unsaturated soil under the isothermal condition was developed to simulate water infiltration into Yolo light clay. The governing equation, that is, Richards' equation, was approximated by the finite-difference method. A normalized sensitivity coefficient was used in the sensitivity analysis of Richards' equation. Normalized sensitivity coefficient was cal...
متن کاملSensitivity Analysis of Hydraulic Parameters in the Simulation of Unsaturated Soil Water Dynamics
Soil water content is one of the most important parameters for estimating irrigation frequency and providing the plant’s water requirement. Since measurement of soil water content is both expensive and time consuming, water movement models are used to estimate these values. In this study, LEACHW model was used to estimate soil water content for two “dry” (20-29 Aug) and “wet” (1-6 Jul) periods ...

متن کاملNumerical simulation of unsaturated soil behaviour
The mechanical behaviour of unsaturated soils is one of the challenging topics in the field of geotechnical engineering. The use of finite element technique is considered as a promising method to solve settlement and heave problems, as associated with unsaturated soil. Nevertheless, the success of the numerical analysis is strongly dependent on constitutive model being used. The well-known Barc...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
