The Erosion & Sediment Control Level 3 course will provide attendees with the opportunity to improve their decision-making process with regards to erosion and sediment management at all stages of the project from planning, design, implementation and finally  through to completion.

This course is delivered in partnership with Terry Clark of Topo.

This course is identified as advanced training with attendee numbers limited to provide the best learning environment, encouraging discussion and engagement. It is not a prerequisite for attendees to have completed the Level 1 & 2 courses, however attendees should have a existing understanding and experience with Erosion and Sediment Control (ESC). Registration for the Level 3 course includes attendance of the Type A, B & D sediment basin design course (day 3).

Attendees will gain knowledge and skills to develop and/or assess an ESC plan against the requirements of the IECA 2008 “Best Practice Erosion and Sediment Control” document and its revised appendices..




  • Environmental impacts and construction phase      water quality performance objectives

  • An understanding of relevant legislation and      requirements

  • Forms of erosion and erosion drivers

  • Erosion risk assessment (RUSLE) and      selection of appropriate sediment and erosion control measures


  • Key soil properties (physical and chemical)

  • Soil sampling and analysis

  • Understanding sodic & dispersive soils

  • Soil pH, fertility, compaction and handling

  • Management techniques for problem soils


  • Role of sediment control measures and      compliance requirements for capture of sediment laden runoff

  • Effectiveness and limitations of sediment      controls

  • Construction and maintenance requirements      for all types of sediment controls

  • Emerging treatment technology including auto      dosers (rainfall and flow based activated) and rapid settling coagulants      & flocculants


  • Principles of drainage design and      construction standards for temporary drains and diversions

  • Use of clean and dirty water diversion      drains to manage runoff and control erosion generation

  • Comparison of drain lining options and rock      check dams

  • Works within a waterway and temporary      crossings


  • Using erosion control techniques to manage      soil stockpiles, stabilised site access, temporary work areas and to      achieve final site stabilisation

  • Comparison of various erosion control      products performance, suitability for nominated works and installation and      maintenance requirements


  • Principles of drainage design and      construction standards for temporary drains and diversions

  • Calculating peak flow using rational      method

  • Manning’s equation and sizing of drains and      chutes

  • Design sizing for sediment basins and      spillways

  • Worked examples and design exercises


  • Requirements of a ESC plan and process to      develop one

  • Plan preparation exercise to prepare staged      plans, identify control measures, locate and size sediment and drainage      control measures and identify suitable erosion control practices


  • Review of basin options (Type A, B & D)      to achieve design standards, including 80% hydrological effectiveness (per      SPP)

  • Design considerations to maximise basin      performance and efficiency, including inlets, outlets, baffles, forebays      and level spreader

  • Coagulant and flocculant types,      effectiveness, treatment process and costs

  • How to determine what treatment product to      use (attendee exercise to perform jar test) along with dose rate      assessment

  • Dosing options including automated systems      and manual dosing

  • Basin construction and QA

  • Performance monitoring and adaptive      management

  • Retro fitting existing basins & storage structures and discussion on learnings from past success and failures

Who should attend?

This course has been specifically designed for people tasked with preparing, implementing or assessing erosion and sediment control plans, including, but not limited to:

  • Engineers

  • Environmental Advisors and Managers

  • Designers

  • Auditors and Regulatory Personnel

Attendees must have an existing understanding and experience with erosion and sediment control.

A base level of knowledge surrounding soils and the fundamentals of hydrology and hydraulics is preferable.

Learning Outcomes 

This 3 day course will address the core theory for candidates wishing to complete assessment requirements  to attain future qualifications.
