Oklahoma-Texas Water Science Center scientists work on a diverse range of projects. We have developed software and tools to facilitate our work and for data sharing.

aqtsra, Utilities for preprocessing raw and approved unit-value time-series hydrometeorological data before statistical endeavors

The aqtsra package in the R language provides a light-weight utility for merging U.S. Geological Survey National Water Information System (NWIS) flat-file tables of raw and approved unit-value time-series data from the AQUARIUS Time-Series software. Provision is made for parsing time stamps, insertion of the day fraction into the year, and days since last site visit among other limited data-inspec

Geoprocessing tools and scripts designed to streamline the workflow required to process map libraries for upload to the Interagency Flood Risk Management (InFRM) Flood Decision Support Toolbox (FDST)

The Interagency Flood Risk Management (InFRM) team’s Flood Decision Support Toolbox is designed to accept flood map library submission from external agencies wishing to contribute to the web application. The geoprocessing of geospatial data comprising the flood map libraries follows set guidelines to facilitate the submission process to the web application. However, the InFRM team understands th

scNIDaregis, Geospatial processing of dams in the United States from the National Inventory of Dams with a state-level aggregation scheme, demonstrated for selected dams in eight states in south-central region of the United States, and post-processing fea

This repository contains R language source code used to read eight tab-delimited text files of state-level instances of the U.S. Army Corps of Engineers National Inventory of Dams (NID). The text file were generated from spreadsheets, which themselves are column-trimmed versions of spreadsheets that were downloaded from the public interface to the NID. The focus of the repository is on reservoir s

Source code in R for creation of regional regression equations for estimation of four hydraulic properties of streams at approximate bankfull conditions for different ecoregions in Texas associated with U.S. Geological Survey Scientific Investigations Rep

This repository contains R language source code used for creation of regional regression equations for estimation of four hydraulic properties of streams at approximate bankfull conditions for different ecoregions in Texas. This code is in support of the following study: Asquith, W.H., Gordon, J.D., and Wallace, D.S., 2020, Regional regression equations for estimation of four hydraulic properties

MGBT, Multiple Grubbs-Beck low-outlier test

The multiple Grubbs-Beck low-outlier test on positively distributed data is supported along, and utilities provided for noninterpretive U.S. Geological Survey (USGS) annual peak-streamflow data processing.

Software - MODFLOW

MODFLOW is the USGS's modular hydrologic model. MODFLOW is considered an international standard for simulating and predicting groundwater conditions and groundwater/surface-water interactions.

API - Stream Trace

The Streamer Trace API is a programming interface written in JavaScript designed to add up- and downstream traces to an ESRI ArcGIS API for JavaScript (ESRI JSAPI) web map using the same methods and services created for the Streamer application. 

API - Graphing Water Information System (GWIS)

GWIS (Graphing Water Information System) Javascript library can create time-series plots of information measured at USGS hydrologic data collection sites across the US. Developed by the USGS Texas Water Science Center, the user-friendly interface integrates the open-source dygraphs JavaScript charting library with the hydrologic data provided by USGS water services.

API - USGS Search

The U.S. Geological Survey Search API is a custom JavaScript library useful for creating a location search widget in a webpage, typically in conjunction with a web map. The widget connects to a database created for the API, or Application-Programming Interface, to quickly find and suggest locations as the user enters text to navigate to areas of interest.
