The 2011 Best Practice Erosion and Sediment Control Road Show, organised by the Australasian Chapter of the International Erosion Control Association, and hosted by the Environment Institute of Australia and New Zealand - South East Queensland Division will begin in South East Queensland during the month of August.

The International Erosion Control Association (IECA) has developed their suite of Best Practice Erosion and Sedi-ment Control (BPESC) documents from a national perspective so that the documents will have the flexibility to deal with the wide-ranging climatic conditions found across Australia.

The BPESC documents are not intended to replace existing State documents, rather they act as a supporting de-sign tool in a manner similar to how Engineers Australia’s ‘Australian Rainfall and Runoff’ and ‘Australian Runoff Quality’ documents support a State’s drainage and floodplain management policies and guidelines.

These talks and training courses will be presented by Grant Witheridge, the author of the BPESC document and will also provide an opportunity for people working in the building, construction, and erosion & sediment control in-dustries to familiarise themselves with the design and application tools provided within this recently finalised suite of documents.

The Presenter Grant Witheridge

All courses are conducted by Grant Witheridge. Grant is the principal author of the best practice ESC documents, as well as publications such as the revised edition of the Queensland Urban Drainage Manual, Fish Passage at Waterway Crossings, and Brisbane City Council’s Natural Channel Design guidelines and creek erosion guidelines. Grant is a civil engineer with 30 years experience, of which 20 years have been spent within the erosion control in-dustry. Since 1995 Grant has conducted over 300 training courses in erosion and sediment control around the coun-try, which have been attended by more than 5000 people.

ONE DAY TRAINING COURSE PROGRAM

Day 1 – Best Practice Erosion and Sediment Control

Part 1 - Detailed overview of the Best Practice Erosion & Sediment Control documents.
This presentation introduces the 6 books that make up the suite of best practice erosion and sediment control documents, and discusses which books are likely to be relevant to the different professions working within the industry.

The presentation also outlines the important features of each book including the principles of erosion and sediment control; the default soil survey standard; default drainage, erosion and sediment control standards; the various technique selection guides; a stepped procedure for the preparation of plans and associated technical notes; plan and sitechecklists; and model codes of practice.

A brief overview is provided on the design fact sheets provided in Book 4, and the field support information provided in Books 5 and 6.

The talk ends with a summary of the major lessons learnt over that past 10 years as the industry adapts the principles of erosion and sediment control to the different climatic regions of Australia. This latter session proposes that even though the basic principles of ESC have not changed over the years, the application of these principles have changed.

Part 2 - Drainage and Erosion Control Techniques
Discussion on temporary drainage control measures includes: principles of drainage control during the construction phase, purpose of catch drains and other temporary drainage control measures.

Discussion on temporary erosion control measures includes: principles of erosion control, use of mulch for erosion control, erosion control blankets, surface roughening, managing dispersive soils, and the use of temporary and permanent revegetation for short and long-term erosion control.

Part 3 - Sediment Control Techniques
Discussion topics include: entry/exit sediment control practices, management of stockpiles, sediment fences, mulch filter berms, grass filter strips, kerb inlet protection systems, sediment traps adjacent pipe inlets and outlets, sediment traps in table drains, rock filter dams, sediment weirs and sediment basins.

Part 4 - De-Watering Sediment Control and Instream Work Practices
Discussion on temporary de-watering sediment control practices includes: bag filters, cartridge filters, filter bags, filter fences, filter ponds, filter tube dams, grass filter beds, settling ponds and stilling ponds.

Discussion on temporary instream sediment control techniques includes:

A 2 day course will be held in Brisbane on 24 & 25 August 2011. This includes day one as above with an additional day covering sizing erosion and sediment control measures.
