Other
•Average Vectored Slope values for each subcatchment are now faster and can account for smoothing. However, please be aware that a new parameter 'Slope Sampling Density' has been added to the Project Options form. Now instead of doing a slope calculation for every perimeter pixel and weighting by length. Only a maximum of this density (default 50) will be analysed. This has been done to speed up the model, particularly if smoothing is turned on.
•Setup a project based on a Google Earth display
•Numerous bug fixes and improvements.
CatchmentSIM 2.2
New view control. •CatchmentSIM's view control has been completely revamped to a Table of Contents / Layer control that is displayed along the left hand side of the CatchmentSIM window, similar to other GIS software such as MapWindow and ArcGIS. •Layers can be added/removed and turned on/off via a right-click menu and the layer attributes can be accessed and modified directly from the view control by double clicking. •'Group Layers' can be added in the view control to facilitate better organization of external vector and raster layers. •The display order of all vector and raster layers can now be modified by 'dragging and dropping'. •Transparency can now be activated for all raster (e.g., DEM, photos) and GIS polygon files (e.g., impervious area polygons). Hydraulic calculations along streams •Hydraulic calculations can be formed along streams. CatchmentSIM can be given a peak flow and Mannings 'n' grid and will automatically extract cross sections at each pixel along a stream and determine the normal depth and velocity (based on Mannings calculation) including automatic adaptation of cross-section width to simulate overbank constraints.

•A comprehensive curve number calculator has been developed to derive curve numbers for subcatchments based on external soils and landuse layers. The calculator includes creation of lookup tables for mapping categories to standard tables, handling of dual hydrologic categories and detailed reporting.

Also, the subcatchments form now also calculates, lake area (and percent coverage) of subcatchments.
More sophistication in automated subcatchment breakup
• A new option for automatically generating subcatchments of an equal size
• A new parameter for all current options that restricts outlet locations to target areas defined by GIS files (for example, road drainage designers may want to automatically place outlets to generate constant sized catchments but they only want outlets to be placed along a set-out line or within a road polygon.
Greatly improved display capabilities
• Now you can customise the line colour, fill colour, line style, line width, fill style and partial transparency of all your display layers.
Improvements to PFS Algorithm
• The PFS Algorithm now includes the ability to set a maximum elevation tolerance for the algorithm. This limits the maximum height that a PFS solution path can breach.
•Ability to automatically assign flats and pits as outlets. This is useful if you would like to map catchments related to local depressions or sinks.
Numerous other improvements including:
•Ability to identify subcatchment outlets based on vector stream networks.
•View / Export subcatchment longest flow paths or main streams (these are different for subcatchments with upstream inputs, main streams refer to the flow path originating from the upstream subcatchment with the largest contributing drainage area whereas the longest flow path is pretty self expanitory)
•Flats and pits added as a permanent drawing layer (the toolbar button now toggles this layer on/off)
•The CSTalk Macro Language has been updated to include Projection, Lake and Ocean variables.
