SUTRA: A Model for 2D or 3D Saturated-Unsaturated, Variable-Density Ground-Water Flow With Solute or Energy Transport
SutraSuite is a collection of software for groundwater modeling in both two spatial dimensions (2D) and three spatial dimensions (3D). It includes the SUTRA groundwater model, the SutraGUI pre-processor, the SutraPrep text-based preprocessor, and the SutraPolot post-processor.
MODFLOW 6: USGS Modular Hydrologic Model
MODFLOW is a popular open-source groundwater flow model distributed by the U.S. Geological Survey.
hyswap
There is a need for water professionals to provide water information in maps and graphics that contextualize data for real-time decision-making. hyswap (HYdrologic Surface Water Analysis Package), is a Python package that provides a set of functions for manipulating and visualizing USGS water data. Specifically, a number of functions for calculating statistics (e.g., exceedance probabilities, dail
Water budget estimation for a water availability assessment across the conterminous United States for water years 2010–2020
This pipeline calculates a simple monthly water budget that includes water supply and consumptive use for thermoelectric, irrigation, and public supply for 12-digit Hydrologic Unit Codes (HUC12) across the conterminous United States for water years 2010-2020. Water budget results also include an assessment of supply and use imbalances within the context of historical climatic conditions to calcula
Evaluating Elk Distribution and Conflict Under Proposed Management Alternatives at the National Elk Refuge in Jackson, Wyoming
This software release contains the code necessary to produce the elk habitat selection models used to support the U.S. Fish and Wildlife Service feeding decisions for the National Elk Refuge. The models project elk space use under five management alternatives: continued feeding, no feeding, reduced ration, halt feeding after CWD threshold is met, and halt feeding after five years of increased harv
Supporting code for: Ungulate personality and the human shield contribute to long-distance migration loss
Bold personality traits act as a precursor to human-habituation, which permits bold elk to reap the forage and predation rewards that occur in suburban landscapes. A multi-pronged approach beyond just maintaining habitat corridors may be necessary to conserve long-distance migrations for species that can become human-habituated. This software runs Bayesian Dirichlet models predicting elk feeding a
sundial
This software release provides a means of inferring the acquisition time of an image using the sundial method. This approach involves measuring the orientation of a shadow on the image and using the calculated solar geometry for that date to identify the time at which the sun would have been positioned so as to cast the observed shadow. The shadow orientation measurement can be made on the image
Workflow to apply the Uniform Manifold Approximation and Projection algorithm to compare streamflow dynamics in hydrologic catchments version 1.0.0
A series of Jupyter notebooks describing the application of uniform manifold approximation and projection (UMAP) to streamflow in hydrologic catchments (examples given for Upper Colorado River Basin) and evaluation of manifolds from modeled and observational data. UMAP produces features that are robust, meaning the resulting images will look similar, even though the underlying data may be differen
digger - Utility tools for landslide runout modeling
Digger is a python package that provides a number of pre- and post-processing tools for landslide runout modeling. Many aspects of digger have been tailored for use with the D-Claw model. It may also be useful for initializing and postprocessing the results of other runout models.
D-Claw requires input files and generates output files in very specific formats. Simulation output generates files in
Mesoscale Explicit Ecogeomorphic Barrier Model (MEEB)
The Mesoscale Explicit Ecogeomorphic Barrier model (MEEB) resolves cross-shore and alongshore changes in topography and ecology
to simulate the ecogeomorphic evolution of an undeveloped barrier or barrier segment. The model is designed to operate over
spatiotemporal scales most relevant to coastal management practices (decades and kilometers). MEEB uses weekly timesteps and
meter-scale cell size.
Oceanographic Time Series Data Processing Library
This is stglib, the USGS Oceanographic Time-Series Processing Library. This Python software package contains code to process data from a variety of oceanographic instrumentation, consistent with the procedures of the USGS Coastal/Marine Hazards and Resources Program.
