In nsw in the richmond river floodplain is the baggotville barrage and the tuckean swamp it is an acid sulphate soil hotspot with a tidal barrage read a general description of the area and the problems they face with acid sulfate soils and water restrictions. Runoff from the tuckean swamp feeds into the richmond river and is occasionally a source of poor quality water the management of the hydrology is one of the most critical issues in ensuring the protection of the reserve’s natural values, water quality and protection from flooding of farmlands within the catchment of the reserve. Unfortunately, those authors only had a very limited quantity of one of the soils remaining (tuckean swamp), which they willingly gave to us and we gratefully acknowledge.

Water issues in the catchment the lower richmond catchment is located in the far-north coast region of new south wales, about 700 km issue downstream, the hydrology of the tuckean swamp has been highly modiﬁed by drains and a tidal barrage this has allowed the shallow water-table to decline in the pyritic estuarine sediments, causing acid.
Prior to drainage tuckean swamp was a mostly freshwater wetland influenced by tidal fluctuations, and mangroves are likely to have occurred 15 kilometres upstream of the present bagotville barrage (figure 1. Map a3 shows the sampling sites for a study (bush et al, 2004a) examining the distribution of mbos in the tuckean swamp drainage network located on the nsw north coast near ballina (map a2. The tuckean was an engine room for fisheries productivity in northern nsw but we now know that the modifications to the hydrology of the swamp, largely through floodplain drainage, resulted in. Unravelling the sources of acidity to nsw estuaries during floods using a novel tracer technique jason de weys , isaac r santos, issues is expensive and laborious when done by traditional means (ie modelling and richmond river found that the tuckean swamp is a major source of acidity to the estuary and a regional groundwater hotspot.
While these issues do not seem to represent major problems at the tuckean swamp site, they may lead to large uncertainties at sites where groundwater inputs are not so obvious below, we discuss these sources of uncertainty and point to directions in which improvements may be needed. The area directly influenced by tuckean swamp (australia), a heavily drained coastal wetland known to be groundwater dominated (santos and eyre 2011 and references therein.

A radon survey along a 120-km long segment of the richmond river demonstrates that the wilsons river and tuckean swamp are areas of preferential groundwater inputs intensive measurements in the tuckean broadwater imply that groundwater inputs are highly variable over hourly and seasonal time scales and related to surface water ph.
Tuckean swamp the landuse changes under the environmental services scheme on the three north coast sites involve modification of drains, fencing, management issues on the coastal floodplains from port macquarie to the queensland border the northern rivers cma are instrumental in. Introduction it is important to have an accurate and reliable measure of the reduced inorganic sulfur (generally assumed to be pyrite) content of acid sulfate soil (ass) materials to avoid inappropriate or unnecessary treatment leading to the possibility of environmental damage or unnecessary cost.
Tuckean swamp (28°58′32″ s 153°24′15″ e) is approximately 5,000 ha of coastal floodplain on the lower richmond river in northern new south wales (fig 1)it has been greatly modified by anthropogenic influences but remains an important economic and environmental resource for the region, for its agricultural, biodiversity and cultural values.
