   EPANET (Environmental Protection Agency Network Evaluation Tool) is a public domain, water distribution system modeling software package developed by the United States Environmental Protection Agency's (EPA) Water Supply and Water Resources Division.

4. FEFLOW - Wikipedia

   en.wikipedia.org/wiki/FEFLOW

   FEFLOW (Finite Element subsurface FLOW system) is a computer program for simulating groundwater flow, mass transfer and heat transfer in porous media and fractured media. The program uses finite element analysis to solve the groundwater flow equation of both saturated and unsaturated conditions as well as mass and heat transport, including fluid density effects and chemical kinetics for multi ...

5. CO2SYS - Wikipedia

   en.wikipedia.org/wiki/CO2SYS

   CO2SYS is a family of software programs that calculate chemical equilibria for aquatic inorganic carbon species and parameters. Their core function is to use any two of the four central inorganic carbon system parameters (pH, alkalinity, dissolved inorganic carbon, and partial pressure of carbon dioxide) to calculate various chemical properties of the system.

6. HEC-RAS - Wikipedia

   en.wikipedia.org/wiki/HEC-RAS

   3D view. HEC-RAS is simulation software used in computational fluid dynamics – specifically, to model the hydraulics of water flow through natural rivers and other channels.. The program was developed by the United States Army Corps of Engineers in order to manage the rivers, harbors, and other public works under their jurisdiction; it has found wide acceptance by many others since its ...

7. Phenyl group - Wikipedia

   en.wikipedia.org/wiki/Phenyl_group

   In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6H5, and is often represented by the symbol Ph (archaically φ) or Ø. The phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve as a ...

9. SMS (hydrology software) - Wikipedia

   en.wikipedia.org/wiki/SMS_(hydrology_software)

   The development of SMS was funded primarily by The United States Army Corps of Engineers and is still known as the Department of Defense Surface-water Modeling System or DoD SMS. It was later ported to Windows platforms in the mid 1990s and support for HP-UX , IRIX , OSF/1 , and Solaris platforms was discontinued.
