Groundwater Data Utilities

Model Data Preparation, Translation and Formatting


The Groundwater Data Utilities are a set of nearly 40 programs designed to accomplish many of the data preparation, translation and formatting tasks required in the course of everyday groundwater modeling and data analysis.
The Groundwater Data Utilities eliminate much of the tedium associated with basic groundwater data processing and model preprocessing. Though written with PEST, MODFLOW and PMWIN in mind, they can be used with other modeling and preprocessing software, or even completely outside the modeling context altogether as a means of interfacing groundwater datasets with contouring and plotting packages such as SURFER and GRAPHER.
Once a user has exported one or two data files in text format from a groundwater database, the following tasks can be accomplished with ease:
Plus much, much more.

grid2arc Writes ARC/INFO "generate" files of the "active" part of the finite-difference grid as defined by a user-supplied integer array.
grid2bln Writes a SURFER "blanking" file of the "active" part of the finite-difference grid as defined by a user-supplied integer array.
grid2dxf Writes a DXF file of the "active" part of the finite-difference grid as defined by a user-supplied integer array.
grid2pt Tabulates the coordinates of the cell centers of the finite-difference grid within an active window defined by a user-supplied integer array.
int2mif Generates MapInfo MIF and MID files based on a MODFLOW/MT3D-compatible integer array.
int2realBuilds a MODFLOW/MT3D-compatible real array based on the contents of a MODFLOW/MT3D-compatible integer array.
many2oneSplits MODFLOW/MT3D-generated unformatted files comprised of multiple two-dimensional results arrays into individual formatted/unformatted files.
mkpmp1Rewrites a metered use file as downloaded from the Queensland Department of Natural Resources groundwater database as a bore pumping file.
mksmp1Rewrites a water level elevation file as downloaded from the Queensland Department of Natural Resources groundwater database as a bore sample file.
mod2smp Interpolates the information contained in an unformatted MODFLOW/MT3D output file to a set of user-specified bores, rewriting the bore-specific data as a bore sample file.
pmp2info Builds a bore information file from a bore pumping file, the former containing cumulative pumped volumes between two user-specified dates for a user-supplied list of bores.
pmpchek Checks the integrity of the data contained in a bore pumping file.
pt2array Builds a MODFLOW-compatible real array; the value assigned to each array element is calculated from information pertaining to points lying within the respective element.
ptingrid Locates the finite-difference cells in which arbitrary, user-supplied points lie; optionally provides the value of an integer or real array element pertaining to the cell containing each such point.
qdig2dxfTranslates the output of the shareware digitizing program, QDIGIT, into DXF format.
qdig2xyzTranslates the "contours" output of QDIGIT to an "xyz" data file.
real2int Builds a MODFLOW/MT3D-compatible integer array based on the contents of a MODFLOW/MT3D-compatible real array.
real2mif Generates MapInfo MIF and MID files based on a MODFLOW/MT3D-compatible real array.
real2srf Translates a MODFLOW/MT3D-compatible real array into a SURFER grid file.
rotbln Rotates a SURFER blanking file about the top left corner of a finite-difference grid so that the component elements of the file can be overlain over the grid when the latter has been rotated such that its row direction is oriented directly east.
rotdat Rotates a data file about the top left corner of a finite-difference grid so that the component elements of the file can be overlaid over the grid when the latter has been rotated such that its row direction is oriented directly east.
rotdxf Rotates a DXF file about the top left corner of a finite-difference grid so that the component elements of the file can be overlain over the grid when the latter has been rotated such that its row direction is oriented directly east.
section Interpolates the data contained in multiple MODFLOW-compatible real arrays to an arbitrary transect line through all or part of the finite-difference grid.
smp2datExtracts information from a bore sample file for a user-supplied list of bores at times corresponding to model output times, generating a bore data file from which PEST input files can be constructed using the PEST MODFLOW/MT3D Utilities.
smp2hydRewrites the contents of a bore sample file for a user-specified list of bores in a form suitable for plotting borehole data against time.
smp2info Time-interpolates the information contained in a bore sample file to a user-specified date for a list of user-specified bores, thus writing a bore information file ready for access by commercial contouring software.
smp2pm1 Rewrites the information in a bore sample file for user-selected bores as a PMWIN observation file.
smp2pm2 Interpolates the information contained in a bore sample file to model output times, then writes the time-interpolated data as a PMWIN observation file.
smpchek Checks the integrity of a bore sample file.
srf2real Rewrites a SURFER grid file as a MODFLOW-compatible real array.
tab2int Generates a MODFLOW/MT3D-compatible integer array from an integer array stored within a GIS.
tab2real Generates a MODFLOW/MT3D-compatible real array from a real array stored within a GIS.
tabconv Translates between integer or real array table files using row/column identifier format and those using cell number identifier format.
twoarray Combines two real arrays by addition, subtraction, multiplication, division and partial replacement.
zone2bln Writes a SURFER "blanking" file of finite-difference grid zonation as defined by a user-supplied, MODFLOW-compatible integer array.
zone2dxf Writes a DXF file of finite-difference grid zonation as defined by a user-supplied, MODFLOW-compatible integer array.


Groundwater Data Utilities are written in FORTRAN 90. The source code is provided so they can be compiled for different machines or altered for a user's specific needs. Executables, compiled with the Lahey FORTRAN 90 compiler, are also provided.
