Familiar with Following Softwares:
RETC (RETention Curve) is a computer program for quantifying Hydraulic Functions of Unsaturated Soils ( Soil Water Retention and Hydraulic Conductivity Functions).
Rosetta is a computer program for estimating Soil Hydraulic Parameters of Unsaturated Soils (Parameters of Soil Water Retention and Hydraulic Conductivity Functions) with hierarchical pedotransfer functions (PTFs) based on Neural Network Analyses.
DISC is a computer software for analyzing measured transient cumulative infiltration data of Tension/Disk Infiltrometer by inverse estimation of Soil Hydraulic Parameters. It is a simplified version of HYDRUS-2D program that numerically solves the Richards' equation for saturated-unsaturated water flow.
4) STANMOD (CXTFIT):
STANMOD (STudio of ANalytical MODels) is a software package for evaluating solute transport in porous media using analytical solutions of the convection-dispersion equation (CDE). It includes several analytical models such as CXTFIT, CFITM, CFITIM, CHAIN, 3DADE and N3DADE. CXTFIT is a code for estimating solute transport parameters using a nonlinear least-squares parameter optimization method (i.e. inverse problem). The program can also be used for solving direct/forward problem to determine concentrations as a function of time and/or position.
HYDRUS is a well-known windows-based software for simulating/modeling the movement of water, heat, and multiple solutes and water uptake by plant root in variably saturated porous media using numerical methods (FEM). The software consists of a computational computer program and an interactive graphics-based user interface for data-preprocessing, discretization of the porous media, and graphic presentation of the results. The program numerically solves the Richards equation for water flow and CDE-type equations for heat and solute transport. The flow equation incorporates a sink term to account for water uptake by plant roots. Dual-porosity and dual-permeability models are also included. HYDRUS also includes parameter optimization algorithm for inverse estimation of soil hydraulic and/or solute transport and reaction parameters from measured transient or steady-state flow and/or transport data. The software can be used for running direct/forward and inverse problems. Three general versions were developed to do modeling in one-dimension (HYDRUS-1D), in two-dimension (HYDRUS-2D) and in three-dimension (HYDRUS-3D).
MACRO is a one-dimensional dual-permeability model for water flow and reactive solute transport in macroporous soil. Soil pore space is divided into a micropore (intra-aggregate pores) and a macropore (inter-aggregate pores) domain characterized by different flow rates and solute concentrations. For the micropore domain, water flow is governed by Richards’ equation and solute transport by the CDE. For the macropore domain, water flow is gravity-driven (no matric effect) and the solute transport assumed to be solely convective (neglecting the effect of diffusion and dispersion). It is assumed that the solute is exchanged between the two domains due to transverse diffusion.
SOILPAR is a windows-based program for estimating Soil Hydraulic Properties of Unsaturated Soils (Soil Water Retention and Hydraulic Conductivity Functions) using several Point and Functional (Parametric) PTFs which were developed by soil and water researchers. It can also be used for fitting of selected water retention models on the measured data.
