The update history of SWMM 5 from the original SWMM 5.0.001 to the current version SWMM 5.2.3 can be found at the EPA website. SWMM 5 was approved FEMA Model Approval Page in May 2005, [ 16 ] with a note about the versions that are approved on the FEMA Approval Page SWMM 5 Version 5.0.005 (May 2005) and up for NFIP modeling.
The SWMM (Storm Water Management Model), the HSPF (Hydrological Simulation Program – FORTRAN) and other modern American derivatives are successors to this early work. In Europe a favoured comprehensive model is the Système Hydrologique Européen (SHE), [ 11 ] [ 12 ] which has been succeeded by MIKE SHE and SHETRAN .
The CompTox Chemicals Dashboard is a freely accessible online database created and maintained by the U.S. Environmental Protection Agency (EPA). The database provides access to multiple types of data including physicochemical properties, environmental fate and transport, exposure, usage, in vivo toxicity, and in vitro bioassay.
EPA has authorized 47 states to issue NPDES permits. [25] In addition to implementing the NPDES requirements, many states and local governments have enacted their own stormwater management laws and ordinances, and some have published stormwater treatment design manuals.
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.
Examples include validation against the wave tank experiment for the Okushiri 1995 tsunami, [11] wave tank runup experiments at University of Queensland, [12] the 2004 Indian Ocean tsunami impact at Patong Beach, [13] comparison to other models, [14] [15] ANUGA was a late entry in the UK 2D model Benchmarking project in 2010 using version 1 ...
Example 1 The linear-reservoir model (or Nash model) is widely used for rainfall-runoff analysis. The model uses a cascade of linear reservoirs along with a constant first-order storage coefficient, K , to predict the outflow from each reservoir (which is then used as the input to the next in the series).
The United States Environmental Protection Agency (EPA) maintains and approves test methods, which are approved procedures for measuring the presence and concentration of physical, chemical and biological contaminants; evaluating properties, such as toxic properties, of chemical substances; or measuring the effects of substances under various conditions.
