An Assessment Of The Efficacy Of Deep Drains Constructed In The Wheatbelt Of Western Australia Part 1 A Discussion On Drainage Implmentation In The Wheatbelt : A Case Study Review, Summary, Conclusions And Recommendations, N A. Coles, Richard J. George Dr, A D. Bathgate

Bulletins 4000 -

Australia has undertaken a strategic review of current and historical deep drainage projects. A 'rapid appraisal' methodology was utilised, based principally on existing hydrological investigations and interpretation and anecdotal evidence provided by landholders to clarify the role of drainage in managing water in dry land rural landscapes.

The objectives of this discussion paper are to:

1. Review the current status of groundwater drainage practice

2. Provide an assessment of deep drains in the landscape and

3. Propose recommendations on the development of drainage policy to enable the application of best management practice in groundwater drainage.

Practical Hints For The Layout And Construction Of 10,000 M3 Circular Dams, Terry Babbington, J S. Addison

Bulletins 4000 -

These notes and illustrations have been compiled to assist earthmovers in the construction of circular excavated earth tank dams, with pipe inlets. Construction techniques tend to evolve over time, so the methods described in this publication will not be definitive, but, they may improve efficiency of construction in the interim. Although the example used in these notes refers to 10,000 m3 dams, the construction techniques, using a bulldozer, described here equally apply to dams of any volume of similar design. Only dimensions will vary. earthmovers using a scarper together with a bulldozer should be able to extract useful information from …
