Technical specifications
All CERC scientific models contain a Technical Summary section in the User Guide, with the exception of the LSMS model, which refers to an associated technical report.
The full technical specification documents for ADMS 6 
, ADMS-Roads 
, ADMS-Urban 
and ADMS-Airport 
are available for download via the links given in the table below.
Most online documents are in Portable Document Format (.pdf)—please download 
Adobe Acrobat Reader to view these files if necessary.
