Environmental impact assessments of the Three Gorges Project in China: issues and interventions

The paper takes China's authoritative Environmental Impact Statement for the Yangzi (Yangtze) Three Gorges Project (TGP) in 1992 as a benchmark against which to evaluate emerging major environmental outcomes since the initial impoundment of the Three Gorges reservoir in 2003. The paper particularly examines five crucial environmental aspects and associated causal factors. The five domains include human resettlement and the carrying capacity of local environments (especially land), water quality, reservoir sedimentation and downstream riverbed erosion, soil erosion, and seismic activity and geological hazards. Lessons from the environmental impact assessments of the TGP are: (1) hydro project planning needs to take place at a broader scale, and a strategic environmental assessment at a broader scale is necessary in advance of individual environmental impact assessments; (2) national policy and planning adjustments need to react quickly to the impact changes of large projects; (3) long-term environmental monitoring systems and joint operations with other large projects in the upstream areas of a river basin should be established, and the cross-impacts of climate change on projects and possible impacts of projects on regional or local climate considered. © 2013 Elsevier B.V.Xibao Xu, Yan Tan, Guishan Yan

Potential horticulture development - Bootu Creek Mine locality : preliminary soil investigation

Made available by the Northern Territory Library via the Publications (Legal Deposit) Act 2004 (NT).The Bootu Creek manganese open cut mine needs to lower the water table to enable dry pit operations below 25 metres. To achieve this, a number of bores in the mine?s surrounds are extracting groundwater. Availability of this extracted water presents an opportunity for its use for commercial horticulture should other relevant aspects meet development criteria. The opportunity to use this water for irrigated horticulture forms a key part of a funding submission, by Centrefarm Aboriginal Horticulture Ltd., to the National Water Commission (NWC), through the National Water Initiative and Water Smart Australia. A collaborative approach between various Northern Territory Government departments has assisted Centrefarm in identifying areas for potential horticulture development: one such area is located near the Bootu Creek mine site. An area to the east of the mine and exploration area, down slope from the water discharge point, is being assessed for proposed irrigated horticultural use.Introduction 1 -- Work program 2 -- Discussion and comments 3 -- Appendix 1.0 - Soil investigation sites -- Appendix 2.0 - Soil classifications -- Appendix 3.0 ?

Alice Springs Roe Creek borefield : hydrogeology of the Pacoota aquifer

Made available by the Northern Territory Library via the Publications (Legal Deposit) Act 2004 (NT).The Pacoota Sandstone lies to the north of and under the Mereenie Sandstone at Roe Creek, and is used to supplement the Alice Springs water supply from the Mereenie Sandstone. Its thickness at Roe Creek is between 400 and 500 m. The Pacoota Sandstone acts as a single aquifer, though with low permeability normal to bedding. This vertical anisotropy results in a lower apparent transmissivity in a north south direction. Bedding plane transmissivity is about 500 m2/d, and the ratio of horizontal to vertical hydraulic conductivity in the range 100:1 to 10 000:1. Siltstone beds near the base of the Mereenie Sandstone appear to form a barrier between this unit and the Pacoota Sandstone. Of the three production bores now in operation only RN 15097 has a significant operating life remaining, at a pumping rate of about 40 L/s. A new production bore should be drilled to the south of RN 13409. The extractable volume in the Pacoota Sandstone to a depth of about 300 m that could be extracted by two production bores pumping at 40 L/s (1.2 GL/year) each is about 290 GL. This estimate is conservative because it has not accounted for the fall in water levels in the Pacoota due to pumping from the Mereenie. The aquifer system is too complex for simple analytical modelling and requires a numerical model. A more detailed analysis of the life of the existing production bores should be undertaken in conjunction with the numerical modelling. As many bores as possible in the Pacoota Sandstone should be geophysically logged with modern digital equipment to create a set of consistent records.Introduction -- Geological setting -- Production bores -- Production pumping -- Hydrogeological setting -- Aquifer properties -- Impact of production pumping -- Recharge -- Flow from the Pacoota Sandstone to Mereenie Sandstone -- Analysis of production pumping -- Water chemistry -- Predicted life of the production bores -- Conclusions and recommendations -- References -- Appendices
