Sample Projects

  • Campbelltown Flood Study +

    CSS was engaged by Campbelltown City Council to prepare a detailed flood study for the Campbelltown Locality. The purpose of the flood study was to define flood behaviour for existing and future conditions. In accordance with the requirements of the NSW Government's Floodplain Development Manual (2005), both mainstream and overland flooding needed to be considered as part of the study.

  • Sydney Harbour Subcatchment Delineation +

    CSS were engaged by the Sydney Metropolitan CMA to complete subcatchment delineation for the Lower Parramatta River, Lane Cove River and Middle Harbour catchments, which occupy approximately 350 km2 of the Sydney urban area.  The project was completed as part of the Sydney Harbour Water Quality Improvement Plan.

  • Parramatta River Source Catchments Modelling +

    CSS was engaged by the Sydney Metropolitan CMA to prepare Catchment Pollutant Export Models (CPEM) for the Upper and Lower Parramatta River catchments. The CPEM were developed for the Sydney Harbour Water Quality Improvement Plan using the Source Catchments software.

  • The Hills Urban Overland Flowpath Mapping +

    CSS were engaged by The Hills Shire Council to map all urban overland flow path alignments in The Hills Shire Council LGA. The purpose of the study was to help identify all allotments that may be traversed by an urban overland flow path and which may be subject to a flood-related development controls (i.e., flood control lots).

CatchmentSIM is a powerful software package for hydrologic analysis of terrain including mapping catchments, flowpaths and integration with hydrologic models.
  • Create a DEM from a wide range of data sources.
  • Remove flat and pits from the DEM using advanced filling and breaching algorithms.
  • Map the drainage path for any point in the terrain.
  • Automatically delineate stream networks complete with Horton ordering and full range of hydrologic attributes.
  • Automatically breakup a catchment into a subcatchment network.
  • Automatic calculation of subcatchment impervious proportions.
  • Integrates with 12d to map drainage catchments for pits and other structures in urban environments.
  • Use bathymetry and lake data to develop stage – area – volume relationships for reservoirs and lakes.
  • Chart a wide range of hydrologic attributes of subcatchments.
  • Visualise your project with 3D OpenGL graphics.
  • Export to GoogleEarth for powerful presentations.
  • Seamless integration with any external software via a macro language. Buit-in scripts allow creation of files compatible with a wide range of software.

Storm Injector provides a powerful interface for implementing Australian Rainfall & Runoff 2016 design storms using a range of Australian hydrologic models including RORB, WBNM and XP-RAFTS. It offers charting and tools for analysing the results of the models to aid in selection of critical durations, flows and hydrographs for hydraulic modelling. Storm Injector is ideal for organisations that want to ensure a consistent approach to ARR 2016 across many hydrologic models such as Councils, developers and consultants.

Features include:

  • Automatic download of Data Hub and BoM IFD Information
  • Coordinate conversion to allow easy derivation of lat/long for data download
  • Download an unlimited number of IFD data-sets to allow spatial variation in rainfall depths
  • Calculate Areal Reduction Factors
  • Calculate initial losses including pre-burst adjustment
  • Create storms based on frequent, rare or normal IFD point temporal patterns, or Areal temporal patterns
  • Create ARR 1987 storms including depth area adjustment
  • Run all storm in your choice of hydrologic model in the background
  • Flexible custom events to assess climate change analysis and sensitivity to initial loss, rainfall increase, partial area effects and others
  • Analyse all results including selection of adopted temporal pattern for each duration and identification of critical duration
  • Create box plots and chart hydrographs for any storm
  • Statistical analysis tools to help inform selection of temporal patterns for hydraulic models
  • Integrate with TUFLOW via rainfall file export and ts1 format hydrograph export

TUFLOW Run Interface Manager (TRIM) is an application to help manage your TUFLOW model runs more efficiently.

  • Easily add any number of TUFLOW models to your queue.
  • Automatically run your models in sequence with any number of simultaneous runs (TUFLOW and TIRM license dependent)
  • Get Email or Skype messages when models finish
  • Add models and check status remotely via Skype
  • Simple progress bar and grid display allows rapid visualisation of model queue progress and model health
  • Easily test one or more models prior to running the entire queue.
  • Charts inflows, outflows and errors on the fly for each simulations.
  • Easy access to log files, key files and directories via right click menu.

CatchmentSIM Rainfall Analyser Launch

We are pleased to announce the launch of CatchmentSIM's Rainfall Analyser module. This tool is the perfect accompaniment to CatchmentSIM to aid in the preparation of hydrologic models with full spatial interpolation of historical rainfall. 

Rainfall Analyser

 

Rainfall Analyser includes the following features:

  • Search for nearby rain gauges and automatically download available daily data from the Bureau of Meteorology website (Analysis >> Find Nearby Gauges) (Australia only).
  • Import multiple rainfall time series from a variety of different file formats (e.g., BoM, MHL, SILO, custom CSV, netCDF grids).
  • Review the historic coverage of all gauges.
  • Identify when significant historic rainfall events have occurred.
  • Determine which gauges were active during each historic event.
  • Re-sample/dis-aggregate daily rainfall information to a sub-daily time step based upon nearby sub-daily gauges, linear interpolation or a user defined temporal pattern.
  • Create rainfall hyetographs and cumulative rainfall charts for each gauge during each nominated historic event.
  • Interpolate rainfall depths and time series between gauge locations using Inverse Distance Weights or Thiessen polygons.
  • Calculate unique rainfall time series for each CatchmentSIM subcatchment (or for other polygons imported from an external GIS file).
  • Create isohyet maps and animations.
  • Export subcatchment-based time series for historic rainfall events to third party hydrologic software to ensure a reliable spatial and temporal description of the rainfall is provided

Please refer to our documentation for more information. Our tutorial is also worthwhile reading.
