FITEVAL
FITEVAL is a program for objective assessment of model goodness-of-fit with statistical significance based on Ritter and Muñoz-Carpena (2013, 2020).
Program to calculate the field Ks method based on the Philip-Dunne permeameter. The permeameter is based on T. Dunne apparatus and data from the Amazon River basin, as presented by Philip (1993). More details on the field application of this permeameter and solution procedure can be found in Muñoz-Carpena et al. (2002).
Vegetative Filter Strip Modeling System (VFSMOD) is a design-oriented vegetative filter strip modeling system. The MS-Windows VFSMOD-W graphical user interface (GUI) integrates the numerical model VFSMOD, a utility to generate source (upslope disturbed area) inputs for the model based on readily available NRCS site characteristics (UH), and advanced uncertainty and sensitivity analysis, inverse calibration and design menu-driven components.
VFSMOD, the core of the modeling system, is a computer simulation model created to study hydrology, sediment and pollutant transport through vegetative filter strips (VFS). The model comprises the following modules:
- Finite element solution for the overland flow equations.
- Green-Ampt infiltration method for unsteady rainfall.
- University of Kentucky grass sediment deposition and filtration.
- Contaminant transport component (first implemented for pesticide reduction within the risk assessment and management regulatory process).
Scripts to create and manage multiple jobs needed to run a typical throughput High Performance Computing (HPC) simulation problem associated with global sensitivity and uncertainty analysis (GSUA).
Here we present a recently proposed framework (Carmona-Cabrero et al., 2024) to analyze stochastic models with an extension of the original GSUA for deterministic models. We will use and ABM (dynamic prey-predator) example provided with the HPC Scripts for GSUA (PreyPredator.jar). We developed 4 jupyter notebooks (Python-3.x kernel ) that follow the 4 main steps in the GSA of stochastic models including the design and analysis of interventions.
This program estimates the 3 parameters (a,n,r) for the van Genuchten's Mualem soil-water characteristic curve formula by using the optimization subroutine LMDIF1 from the math library MINPACK (Argonne National Laboratory). VGPest3 reads the Soil and Water Characteristic Curve (SWCC) laboratory values, water content (, cm3/cm3) vs suctions (h, -cm water) and calculates the parameters.
The program follows the method of Chu (1978), Mein and Larson (1971, 1973) and Skaggs and Kaheel (1982) to calculate infiltration for unsteady rainfall using the Green-Ampt equation.
SWINGO (Shallow Water table INfiltration alGOrithm) is a Fortran command line program to calculate infiltration for soils bounded by a shallow water table.
The program consists of a time-explicit infiltration solution based on a combination of approaches by Salvucci and Entekhabi (1995) and Chu (1997) with the assumption of a horizontal wetting front.
There are two Elementary Effects (EE) packages that complement the analysis: a) EE Sampling - to obtain the Morris samples based on a number of methods, including Sampling for Uniformity (SU); and b) EE Measures and Plots - after running the model with the EE samples it post-processes the results and provides Morris statistics and plots.
Program to calculate soil infiltration and redistribution during a series of storms for 1D (vertical) and 3D (point source, drip/trickle) using Muñoz-Carpena and Gowdish (2009, 2018) MGAR method. The program is written in fortran 90 and compiled with Fortran intel 2018 (note that incompatibilities with gfortran or gf95 might exist). Fortran source code, windows executables and sample files are included in the package.
