Carlson Hydrology 2011—Here’s automation you can use to meet your hydrology needs. Full 3D road and lot design feeds directly into flow calculations and drainage design. Hightlights of the 2011 Hydrology release include: Redesigned and enhanced sewer spreadsheet editor for working in profile view. Added support in sewer network for multiple pipes between structures and for separate inlet locations. Carlson Hydrology 2011 is tightly intergrated with HydroCAD®. This collaboration brings together the extraordinary ease of use that Carlson is known for, its 20+ years of experience mastering the civil/survey CAD environment, with the 20+ years of experience of HydroCAD in the unique, rapidly changing and highly regulated stormwatere modeling profession. The Carlson 2011 line of software comes with 64-bit capabilities, is Windows 7 compatible, and works on AutoCAD® 2011.

From Carlson Software, you get complex calculations of surface flows integrated with the DTMs. Tap extensive libraries on rainfall, inlets, manholes, outlets Calculate inlet intercepted and bypass flows, gutter spread and depth, pipe flow depth and velocity, and hydraulic and energy grade lines Get warnings for collisions, excessive pipe lengths, insufficient cover, lack of slope, excessive flow rates, and more Track runoff and analyze watershed – choose entire area or the watershed above a point such as a catch basin Design ponds, culverts, channels and outlets Draft sewer pipe dynamically in plans, profiles and 3D Here's how it all works with HydroCAD: Start with a drawing, preferably georeferenced Define the Hydrologic Soil Group areas and identify them with plain CAD text, A, B, C, or D Define Ground Covers areas as closed polylines on user-defined layers Define and label watersheds and longest flow paths for Tc calculations Specify the surface TIN model for the site Next, start Carlson's new HydroNET® Explorer and pick Update All for automatic extraction of precise subcatchment sub-area data. Carlson does all the work to combine and analyze all of the project specific data in your drawing and Export to HydroCAD exactly what it needs to perform the stormwater modeling. All of the tedious data extraction is done instantly, saving you hours of work.
