These release notes describe the new feature improvements, operating system requirements, and installation types for xpdrainage.

List of Improvements in 2018.2

HEC22 Inlet Options

Automatically calculate inlet capacity using HEC22 Methodology from plan data, analysis results or manual flow entry. Preview gutter size and effectiveness in plan and cross-section view for ease of understanding.

Simplified Modified Rational Method

Available as a Static Analysis option to comply with a variety of US regional runoff requirements to use the Simplified Modified Rational Method triangular hydrograph approach.

Import / Export Text Files (.csv, .xls and .txt)

Save time building networks by communicating with more packages with a variety of text formats. Loads and saves data for Inflows, Junctions, Connections and Stormwater Controls.

Pipe Sizing for Minimal Excavation

Updated Pipe Sizing routine to lay the flattest gradient pipes that meet required criteria will minimize excavation and reduce construction costs. In addition, automatically size to meet max velocity, size pipes downstream of flow controls and include backdrops – all with easily visible warnings summarized to aid engineering adjustments.

Rainfall Viewer 

View and Export rainfall before or after analysis to check, edit and reuse rainfall generated in xpdrainage.

Edit in Profile View

Speed up network editing by using the Profile Summary Table to edit values and see live updates.

Update Levels from New Surface Data

Avoid manual data entry by automatically updating cover levels when a new surface is loaded. With user entered data optionally maintained.

Rainfall IDF Table Supports NOAA ATLAS 14 File Format

Comply with US Requirements to use the latest rainfall database.

FEH 2013 Support

Comply with UK Requirements to use the latest rainfall database.

List of Improvements in 2018.1

Preliminary Pipe Sizing. Step more easily through the steps needed to complete the preliminary pipe sizing part of your stormwater design. Use this as the first step to sizing before running full analysis. Or stop here and submit your pipe sizing report for approval.

Preliminary Sizing Ribbon. Find all the tools for your preliminary pipe sizing in one place to save time navigating between different parts of the software.

Pipe Sizing Wizard. Step through setting up Pipe Sizing Criteria, reviewing proposed changes and producing a full Pipe Sizing Report quickly and easily.

More Pipe Sizing Options. To reduce the number of manual changes needed minimum and maximum gradients for different pipe sizes and fixed slopes have been added to the sizing options.

Pipe Sizing Report. Quickly view and output rational method pipe sizing reports in standard HEC-22 format or customizable, reusable layouts to meet local requirements.

IDF Table. Now set up multiple return periods / average recurrence interval IDF tables instead of individual rainfall collections. Use our pre-populated templates for NOAA Atlas 14, KOSTRA 2000 and KOSTRA 2010 IDF Data or create, save and re-use custom templates for your region.

Extended Preliminary Sizing Options. Setup separate preliminary sizing (rational method) and dynamic analysis options in the same catchment areas to take account of different methodologies available.

NEW Chamber Stormwater Control. Quickly layout Arch, Circular and Rectangular chambers or create and reuse custom chambers for stormwater storage. Visually see them laid out on plan with export to CAD and GIS options available.

Rational Method Cv Calculator. Using widely used tables of suggested runoff coefficients this built in calculator speeds up defining catchment characteristics. Local guidelines may differ from the calculator values and where values differ the locally recommended values should be used.

Seasonal Cv Values. Required in the UK by the Wallingford Procedure with FSR and FEH rainfall methods, summer and winter Cv values can be used to enable one simulation to run all storms required for design.

Additional Pipe Roughness. Now choose between Colebrook-White pipe roughness coefficient or Manning’s n values to suit your local guidelines and requirements.

List of Improvements in 2017.3

GIS Export Wizard

You can now export a full design or individual elements, the layout and design parameters in a format of your choice to better record and communicate asset data. Remember the format used to save time in the future when communicating with multiple authorities.

Plot Profile and CAD Export

Print scaled plots of longsection profiles to be used on site or export to CAD for inclusion in final drawings providing the next step towards building a drainage design.

Take Off Data

In overall system Summary format, or detailed for Junctions, Connections or Stormwater Control data, a volume and dimension report can be produced as a step towards costing your project. See totals for manhole and pipe types or on an individual basis. Export to Excel or PDF to include in reporting or complete costing information.

Box Culvert

Connections options expanded to include box culverts with or without splay at the corners for structural support.

Synchronise Manhole Invert Levels

Save time editing network details by synchronizing all manhole levels to bring them in line with pipe inverts in the click of a button.

List of Improvements in 2017.2

Huge Profile Revamp - Fully compatible with zoom and pan functions the new flexible representation of the drainage network in profile view makes it easy to spot mistakes, visualize the HGL and export to CAD for completed drawings needed on site.

Robust GIS Import - Build models more quickly by importing inflows, connections, junctions and stormwater controls and mapping recorded parameters in an easy to use wizard. Save the mapping format for future use. Provides support for the most common local authority data format.

SBUH Runoff Method (USA) - You can now meet local requirements where SBUH is required.

Variable Outfall Matrix - Easily enter complicated matrices of variable outfall data per storm event for situations where the outfall level varies through different rainfall events. With easy storage of data this setup saves hours of individual runs and results extraction and avoids multiple files.

Welcome Screen - Easier to get started with software with all the features you would expect.
