Here’s the automation you’ve been looking for! Full 3D road and lot design feeds directly into flow calculations and drainage design – Carlson Hydrology 2009 means the end of hand entry of runoff coefficients and guessing-game calculations of flows over surfaces.
It’s a Carlson Software first! Complex calculations of surface flows are 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
General
- Built on AutoCAD: Runs in AutoCAD versions 2009 to 2000 as well as AutoCAD Map, LandDesktop and Civil3D and on IntelliCAD 6.4
- Project Setup: Flexible data storage methods
- Drawing Cleanup: Fix common drafting errors
- Drafting Enhancements: Handy tools for working in AutoCAD such as Join Nearest, Shrinkwrap Entities, Polyline Utilities, Drawing Inspector, Layer Inspector and Twist Screen
- Data Compatibility: Supports industry standard LandXML and scores of specific data conversions
Surfaces- Build Surfaces: By triangulation or rectangular grids
- Contouring: One step triangulate and contour from 3D entities as well as contouring from surface files
- Slope Analysis: Label and report surface slopes at selected points and slope zone analysis
Watersheds- Watershed Analysis: Watershed delineation, ponding analysis, and real-time inspector for flows and drainage areas
- Runoff Tracking: Draws 3D flow lines that follow the surface model
- Peak Flow: Calculate peak flow by various methods from runoff parameters of storm event, drainage area, time of concentration and runoff coefficients
- Hydrographs: Route hydrographs from multiple watersheds through ponds and channels using TR-20
Hydraulic Structures- Pond Sizing and Design: Detention pond sizing, bench and valley pond design, stage-storage calculation and graphs
- Spillway, Weir, Orifice, Culvert, Channel Design: Routines to design the dimensions and flows for structures plus reports and drafting for them
- Multiple Outlet Design: Combines orifices, weirs, drop pipes, culverts and user-defined outlets to design the overall stage-discharge
- Stage-Storage and Stage-Discharge: Routines to input, edit, report and draw
Sewer Networks- Define Inlets, Structures, Pipes, Storm Events: Setup libraries with parameters for these network components
- Layout Structures and Pipes: Place structures and set pipe connections
- DTM-Based Runoff: Calculates drainage area, time of concentration and weighted runoff coefficient from inlet location on surface model. DTM also used to figure minimum cover for pipes
- Analyze Flow: Calculate inlet intercepted and bypass flows, gutter spread and depth, pipe flow depth and velocity, and hydraulic and energy grade lines
- Size Pipes and Set Inverts: Apply flow analysis to have program set pipe size and/or invert elevations
- Collision Conflicts Check: Reports any collisions between networks within specified tolerance
- Draw Sewer Network: Draw structures and pipes in plan view, in 3D using 3D Faces and in profiles
