Its intuitive interface make it easier than ever to design and analyze storm sewer systems from gutter to outlets. It provides calculations for catchment runoff, gutters, inlets, junctions, pipe networks, and outfalls. Available in Stand-alone and AutoCAD interfaces, StormCAD included automated constraint-based design features for construction elements, scenario and data management, and reporting capabilities.CivilSTORM: It is use to analyze and design storm sewer systems using a peak flow (rational method) based approach. CivilSTORM is ideal for Land developersStormwater Master PlannersMunicipal EngineersPlan ReviewersConsulting engineersIt performs a full range of analysis necessary for verification of hydraulic capacity and demonstrating stormwater compliance in complex storm water handling systems. Its dynamic calculation engine handles capacity analysis, detention, looped systems and diversionsTime Saving model management tools such as scenario manager, FlexTables, FlesUnits, and engineering libraries make CivilStorm both highly cost-effective and extremely flexible.It provides calculations for catchment runoff, gutters, inlets, junctions, pipe and prismatic channel networks, and outfalls. Its intuitive interface makes it easy to design and analyze these components.CivilStorm can run on one of these three (3) platforms: Stand-alone, MicroStation, or AutoCAD. Out of the box, CivilStorm users can work within Stand-alone and MicroStation platforms, while AutoCAD integration is available as an optional addition.Regardless of the platform used, CivilStorm’s stand-alone, MicroStation and AutoCAD maintain a singles set of modeling files for true interoperability across platforms. CivlStorm’s stand-alone, MicroStation and AutoCAD platforms offer unique platform freedom and verslity.PondPark: It helps in saving hours of manual calculation time when analyzing pre-and post-development hydrology. PondPack’s robust analysis engine sizes ponds develops outlet rating curve with tailwater effects, accounts for pond infiltration, calculates pond detention times, analyzes channels, performs interconnected pond routing computations, and handles divergent (multiple) outfallsWith a single Stand-alone software package, you will be able to analyze, design, manage and plan detection pond projects of any size quickly, correctly and within budget.Most importantly, you will be able to submit agency ready reports. PondPack’s intuitive interface allows even a novice user to produce a customized professional report complete with a table of content and an index.CulvertMasters: It is use for solving culvert hydraulic problems. Incredibly flexible, fast, report-ready, and stress-free, CulvertMaster builds on the input you have on-hand while providing you with any unknown design variables such as headwater depth, discharge, or culvert size.Analyze system with multiple barrels, difference shapes and sizes, special tailwater considerations and roadway overtopping considering watershed data, culvert characteristics and even weir geometry.Automatically caompare and incorporate several design trials into complex hydraulic analyses and evaluate the results using the built-in culvert Designer utility. It streamline complicated culvert hydraulics and delivers the results you need.It helps in evaluate existing culverts and compare numerous design options with ease. Use the built-in FHWA HDS-5 methodology, SCS and rational hydrology, and robust gradually varied flow hydraulics to deliver culvert designs that will stand the test of time.Quick Culvert Calculator: For simple culverts with known characteristics, use the Quick Culvert Calculator to plug in the data you know and solve for what you need.Culvert Analyzer: for more complex systems with multiple barrels, dirrerenc shapes and sizes, special tailwater considerations, and road overtopping, make use of the Analyzer. Incorporate whatever data you have, including watershed data, tailwater conditions, culvert characteristics and even weir geometry.Culvert Designer: Use the Designer to compare several proposed options. Incorporate these design trials into complex hydraulic analyse and evaluate the results.With all these options, just click a button to create a new “worksheet”, enter your data in the clearly labeled fields, and click to solve. The data entry and manipulation are flexible and straight forward.FlowMaster: To quickly perform hydraulic calculations for dozens of element types, form pipes and open channels to drop inlets and weirs. It solve for any unknown properties, design for any desired characteristics, and produce detailed reports and rating curves on the fly.Its interface is simple to be the easiest model you have ever used, yet so powerful, you will be solving real problems in just minutes.Features: Gradually varied flow: Perform gradually varied flow analysis and generate profiles for pipes and open channels.Project Explorer: Work on multiple projects simultaneously and safe them for future use.More Element Types: Expand your hydraulic toolbox with new worksheets for parabolic channels and box and elliptical pipes.Flexible Interface: Configure toolbars and dock windows to create work environment that match your workflows.Customizable graph: take complete control over every facet of rating curve.
