Modeling and Software Modeling and Software

Hydrologic modeling and analysis tools are important components of NAWQA studies. The types of modeling and analysis tools that play a large role in NAWQA include: Statistical models and analyses, Geographic information system (GIS) analyses, Process-based models, and Hybrid statistical, GIS, and process-based models.

ModelMate ModelMate

ModelMate is a graphical user interface (GUI) designed to facilitate model analysis by software applications that invoke model simulations as external processes.

Multidimensional Surface-Water Modeling System (MD_SWMS) Multidimensional Surface-Water Modeling System (MD_SWMS)

The U.S. Geological Survey’s (USGS) Multi-Dimensional Surface-Water Modeling System (MD_SWMS) is a pre- and post-processing application for computational models of surface-water hydraulics.

National Oil and Gas Assessment National Oil and Gas Assessment

See and download summary maps and tables of U.S. oil and gas assessment results.

New York Streamflow Estimation Tool New York Streamflow Estimation Tool

The New York Streamflow Estimation Tool produces a complete estimated daily mean time series from which daily flow statistics can be estimated and a means for quantitative flow assessments at ungaged locations to restore and maintain the chemical, physical, and biological integrity of the Nation’s waters.

PESTCommander PESTCommander

PESTCommander is an object-oriented Graphical User Interface (GUI) written in Python® that facilitates the management of model files ("file management") and remote launching and termination of slave computers across a distributed network of computers ("run management").

Point-source to finite-fault distance conversions Point-source to finite-fault distance conversions

Produce approximated finite fault distances and variance corrections given point source information, e.g., Repi (epcentral distance) to Rrup (rupture distance).

PRESENCE PRESENCE

Estimates patch occupancy rates and related parameters.

Protected Areas Data - U.S. (PAD-US) Protected Areas Data - U.S. (PAD-US)

A National inventory of U.S. terrestrial and marine protected areas that are dedicated to the preservation of biological diversity and to other natural, recreation and cultural uses, managed for these purposes through legal or other effective means.

qfasar: Quantitative Fatty Acid Signature Analysis in R qfasar: Quantitative Fatty Acid Signature Analysis in R

Knowledge of predator diets provides numerous insights into their ecology. Diet estimation therefore remains an active area of research in quantitative ecology. Quantitative Fatty Acid Signature Analysis (QFASA) is a method of estimating the diet composition of predators. The fundamental unit of information in QFASA is a fatty acid signature (signature), which is a vector of proportions...
