The Cyanobacteria Assessment Network (CyAN) is a multi-agency project to develop remote sensing technology using satellite data to provide early warnings for cyanobacteria and algal blooms in U.S. lakes and reservoirs. To support remote sensing efforts by CyAN, validating satellite imagery is critical to developing early warning indicators for cyanobacteria and algae blooms. This open...

Digital Shoreline Analysis System version 5.0

These programs are an implementation of the Direct Green’s Function method described by Friederich and Dalkolmo (1995) and Dalkolmo (1993).

DTSGUI is a USGS software tool to import, manage, parse/cull, georeference, analyze and visualize fiber-optic distributed temperature sensor data.

Magnetotelluric impedances and other similar transfer functions are important for geophysical interpretation and for space weather hazards. I helped develop and continue to curate a database known as IRIS EMTF, http://ds.iris.edu/spud/emtf which uses something called EMTF XML format for storing the data. EMTF FCU v4.1 software consists of a set of freely available format conversion tools...

est_noise is a time-series analysis program that allows the user to fit various, standard functions to their data (rates, offsets, rate-changes, sinusoidals, exponentials, and/or user-defined functions) and simultaneously quantifies the amount of temporal correlation in the time-series data.

The Floodplain and Evaluation Tool (FACET) is an open-source python tool that maps the floodplain extent and derives reach-scale summaries of stream and floodplain geomorphic measurements from high-resolution digital elevation models (DEMs).

FACET is a Python tool that uses open source modules to map the floodplain extent and derive reach-scale summaries of stream and floodplain geomorphic measurements from high-resolution digital elevation models (DEMs). Geomorphic measurements include channel width, stream bank height, floodplain width, and stream slope. FACET allows the user to hydrologically condition the DEM, generate...

FPFIT is a Fortran program that computes double-couple fault plane solutions from P-wave first motion data using a grid search method.

GCLAS is a program designed to compute daily and annual loadings of constituents transported in rivers.

HASH is a Fortran 77 code that computes double-couple earthquake focal mechanisms from P-wave first motion polarity observations, and optionally S/P amplitude ratios.

The Highway-Runoff Database (HRDB) was developed by the U.S. Geological Survey (USGS), in cooperation with the Federal Highway Administration (FHWA) Office of Project Delivery and Environmental Review to provide planning-level information for decision makers, planners, and highway engineers to assess and mitigate possible adverse effects of highway runoff on the Nation's receiving waters...
