Leschenault Peninsula : A Study Of Land Resources And Planning Considerations, Veronica P M Oma
Leschenault Peninsula : A Study Of Land Resources And Planning Considerations, Veronica P M Oma
Resource management technical reports
Leschenault Peninsula is a fragile coastal dune barrier north of Bunbury, Western Australia. Most of the landforms are highly, or potentially highly, unstable and are not capable of sustaining tourism uses other than walking tracks. Minor areas close to Leschenault Inlet are more stable and could be developed for a range of tourism uses including accommodation and day tripper facilities. However, much of the Peninsula is highly degraded and susceptible to wind erosion, while disposal of acid-iron rich li id effluent from the Laporte (SCM) works in lagoons located within the dunes, has contributed to the visual degradation of the …

Catchment Salinity : Report On A Study Of The East Perenjori Catchment, C J. Henschke
Catchment Salinity : Report On A Study Of The East Perenjori Catchment, C J. Henschke
Resource management technical reports
Dryland secondary salinisation has debilitated large areas of land in Western Australia due to clearing of native vegetation for agricultural development. The initial aim of the project (which is the subject of Part I of this report) was to establish a landscape framework for hydrogeological examination of the salinity problem. A catchment of 139 km2, located 30 km east of Perenjori townsite was selected for detailed study. It was mapped for soils, vegetation, topography, landform and salinity using both old and recent aerial photography. A field survey of soil hydraulic conductivity was undertaken to help define recharge areas. Soil-vegetation associations …

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 …

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 …

Management Of Native Vegetation On Farmland In The Wheatbelt Of Western Australia, A M. Coates
Management Of Native Vegetation On Farmland In The Wheatbelt Of Western Australia, A M. Coates
Resource management technical reports
Clearing in the wheatbelt region of Western Australia has been rapid and extensive. The mapping of remnant vegetation in the shires of Dumbleyung, Lake Grace, Pingelly and Tammin with the use of the most recent aerial photography (1984) demonstrates the extent of clearing especially in the old established farming areas. Only 7 per cent of the Tammin shire had been retained under native vegetation, 10 per cent of the Dumbleyung shire and 14 per cent of the Pingelly shire. In the Lake Grace shire where large areas have only recently been developed for agriculture, approximately 31 per cent had been …

Preliminary Groundwater And Salinity Investigations In The Eastern Wheatbelt. 3. Welbungin And Beacon River Catchments, Richard J. George Dr, P W C Frantom
Resource management technical reports
Water-tables show no obvious signs of a nett annual rise in the bores monitored in the valley floor, lower slope areas over the three year period. Groundwaters are extremely saline, the sedimentary and saprolite aquifers permeable (hydraulic conductivity range 0.1-2.0 m/day) (0.0001). Future management systems should seek to decrease recharge by changing rotations and farm practises while increasing discharge by using trees, pumps and halophytes. Options are available for drainage.
Drains : A Method Of Financially Assessing Drains Used To Mitigate Waterlogging In South-Western Australia, John S. Salerian, D J. Mcfarlane
Drains : A Method Of Financially Assessing Drains Used To Mitigate Waterlogging In South-Western Australia, John S. Salerian, D J. Mcfarlane
Resource management technical reports
Seepage interceptor drains are often effective in mitigating waterlogging in duplex (sand over clay) soils on hill slopes in the sout-west. Spoon and W drains are sometimes effective in removing excess surface waters form clay flats.
This report outlines a method to determine the long-term (1 to 20 years) cost-effectiveness of installing drains to mitigate waterlogging for each individual situation.

A Land Resource Survey Of The Fall Point Coastline, Broome, W.A., P A. Hesp, P J. Curry
Resource management technical reports
The purpose of this study was to find a suitable location for a bird observatory and provide adequate coastal land resource data for the area. The main selection criteria and conditions were: the location was closely adjacent to major wader roosting and feeding sites; all-seasons access was required; the location provided a site of around 2 1/2 hectares to provide space for one or more buildings, camp ground and associated facilities ; anticipated access tracks, site developments and levels of use.
