Conduit Flow Process (CFP) allows simulation of laminar and turbulent flow within a standard MODFLOW layer and/or simulation of a hybrid model (one-dimensional pipe network coupled to MODFLOW).

@USGSted (USGS Twitter Earthquake Dispatch) distributes Twitter alerts for earthquakes worldwide with magnitudes of 5.5 and above. When citizens feel shaking activity, they often use the popular social media application, Twitter, to "tweet" what they are experiencing.

This web application can be used to calculate risk-targeted ground motion values in accordance with “Method 2” of 2010 ASCE 7 Standard Section 21.2.1.2.

Overview The highway-runoff database (HRDB) was developed to serve as a data warehouse for current and future highway-runoff data sets. The database can be used by transportation agencies and researchers as a data warehouse to document information about a data set, monitoring site(s), highway-runoff data (including precipitation, runoff, and event mean concentrations).

OTEQ is a mathematical simulation model used to characterize the fate and transport of waterborne solutes in streams and rivers. The model is formed by coupling a solute transport model with a chemical equilibrium submodel. The solute transport model is based on OTIS, a model that considers the physical processes of advection, dispersion, lateral inflow, and transient storage.

The Delaware River Basin Streamflow Estimator Tool (DRB-SET) estimates baseline and altered streamflow at a daily time step for ungaged stream locations in the Delaware River Basin for water years 1960-2010.
