Carlton Plains Soil Survey In The Shire Of Wyndham, East Kimberley, T C. Stoneman
Carlton Plains Soil Survey In The Shire Of Wyndham, East Kimberley, T C. Stoneman
Resource management technical reports
The Carlton Plains covers approximately 11,750 ha midway between Wyndham and Kununurra on the northern bank of the Ord River in the Shire of East Kimberley. The survey area is divided into two geomorphic units, the clay plains and the levee areas. Soils of the former generally belong to the Cununurra family of cracking clays while those of the levees are generally more variable and of medium texture.Samples of the major soils were collected for mechanical analysis and basic chemical analysis.Sodium chloride percentages and exchangeable sodium percentages are both high on the clay soils of the western plain. The suitability …

Salinity In Western Australia : A Situation Statement, V T. Read
Resource management technical reports
The Select Committee on Salinity was established by the Legislative Council of the Parliament of Western Australia in November 1987 to inquire into and report on salinity in Western Australia giving particular regard to:
• what action has, or is being taken, to assess the magnitude of the problem;
• what form of action can, or should, be taken to control salinity;
• what legislative of administrative acts or incentives to the private sector are necessary or desirable to assist further in controlling or eradicating salinity.
Members appointed to the Select Committee were the Honourable David Wordsworth (Chairman), the Honourable …
Preliminary Groundwater And Salinity Investigations In The Eastern Wheatbelt 2. Merredin Catchment, Richard J. George Dr, P W C Frantom
Preliminary Groundwater And Salinity Investigations In The Eastern Wheatbelt 2. Merredin Catchment, Richard J. George Dr, P W C Frantom
Resource management technical reports
Saline groundwater occurs within twelve metres of the surface throughout the valley of the Merredin catchment. Saline groundwater occurs within deep sediments deposited in the valley and deeply-weathered bedrock materials. Rapid groundwater recharge appears to be taking place in sandy-textured soils high in the landscape and directly into the Cainozoic sediments in the valley floor. Water-tables are rising at approximately ten centimetres each year in the upper catchment area.

The Use Of Permeability, Conductivity, Conductance And Resistance In The Description Of Water Movement In Soils And Plants, H Borg
Resource management technical reports
Permeability, conductivity, conductance and resistance are important parameters in the description of water movement in soils and plants. These terms are related, but not synonymous. Permeability is only a function of the flow pathgeometry of the medium, while conductivity also depends on the fluid involved. Conductance, in addition, takes the size of the medium into account. Resistance is simply the inverse ofconductance. By applying the definition of resistance, it isshown that Darcy's law and Ohm's law are equivalent. Conductance and resistance relate volume flow rate to a potential difference, but to relate volume flux (volume flowrate per unit area) to …
