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.

  • 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.

Storm Injector Released

We are happy to announce that Storm Injector has officially been released. Storm Injector is available on an annual subscription. Prices can be viewed here.

Watch our videos: 

Storm Injector automates many steps including:

  1. Downloading required data from the ARR Data Hub and the Bureau of Meterology IFD website for a given latitude / longitude and catchment area
  2. Create potentially hundreds of model runfiles based on the user's selections
  3. Run all models through the selected hydrologic model including parallel processing
  4. Analyse the results in both tabular and graphical formats

Here are some important links:

CatchmentSIM Update & FMA Presentation

We are pleased to announce a new release of CatchmentSIM that brings Kriging and Natural Neighbour Interpolation to the Rainfall Analyser module and the Interpolate Grid from Points tool. These methods offer improved interpolation for rainfall observations and most types of point data. Click the Read More link to see some examples of how significantly rainfall isohyets can vary based on the interpolation method.

 

We are also happy to release our paper and presentation from this year's Floodplain Management Authorities conference in Brisbane. The paper discusses how we tackled the problem of applying freeboards in areas of overland flooding. This is an important area of research considering the increasing focus on flood risk in urban catchments. Some further information is included in the Read More link.

TRIM: Manage TUFLOW Simulations Across a Cluster of Computers

We're pleased to announce the latest version of TIRM (2.6.0) now allows a simulation queue to be distributed over a cluster of modelling computers and managed from a single location. This ensures optimum TUFLOW license utilisation and modelling speed. TRIM will prioritise simulations to the fastest and most appropriate computers and notify if they go offline for any reason. We have prepared a quick 5 minute video that outlines the new feature and important considerations when using it.

You can also download a free 45 day trial of an 8 simultaneous simulation version of TIRM from our website.

Finding New High Ground in Emergency Response Planning Classification

Recently, we've been undertaking some interesting research on applying Emergency Response Planning (ERP) classifications at much finer scales than previously possible. This has been achieved by the use of automated analysis using an adaptive road network algorithm that senses when a road becomes impassible in a flood and searches for an alternative route. CSS Principal, David Tetley presented this work at the 2014 Floodplain Management Authorities conference in Deniliquin and received a Highly Commended Paper award.
