An Inventory Of Rangelands In Part Of The Broome Shire, Western Australia, W E. Cotching Jan 2005

An Inventory Of Rangelands In Part Of The Broome Shire, Western Australia, W E. Cotching

Technical Bulletins

The inventory of rangelands in part of the Broome Shire in Western Australia was undertaken by DAFWA between 1989 and 1990. It describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The survey of part of the Broome Shire …

Two-thirds (580.000 ha) of the sub-region has been cleared for agriculture This publication describes the groundwater trends, risk of shallow watertables, and technical feasibility of salinity management within the agricultural land

Soil-landscape zones are spatial units based on geology and geomorphology. Since most groundwater processes …


Groundwater Trends In The Kent-Frankland Sub-Region, Arjen Ryder Jan 2004

Groundwater Trends In The Kent-Frankland Sub-Region, Arjen Ryder

Natural resources published reports

The South Coast Regional Initiative Planning Team (SCRIPT) has divided the South Coast region of Western Australia into six sub-regions. Kent-Frankland covers the catchments of the Frankland, Gordon and Kent' Rivers. Approximately two-thirds (450,000 ha) has been cleared for agriculture. This publication describes the groundwater trends, risk of shallow watertables, and technical feasibility of salinity management on agricultural land.

Soil-landscape zones are spatial units based on geology and geomorphology. Since most groundwater processes in WA are controlled by the geologic and regolith properties, these zones can be used for allocating hydrological attributes, such as groundwater characteristics and trends. The hydrological …


Groundwater Investigation On Victoria Location 8565, East Binnu, Russell John Speed Nov 2003

Groundwater Investigation On Victoria Location 8565, East Binnu, Russell John Speed

Resource management technical reports

Describes a drilling investigation undertaken for the East Binnu area within Victoria location 8565, Western Australia.

Climate: Past, Present, And Future, Saxon E. Sharpe, Rick Forester, Amy J. Smiecinski

Publications (YM)

Climatology and meteorology studies in the Yucca Mountain area have resulted in the following key observations and conclusions: • The present-day arid climate of the Yucca Mountain area can be understood in terms of global-scale atmospheric circulation and regional to-local physiographic features. In general terms, the area is under the influence of mid-latitude westerly winds and associated storm systems during the cool part of the year and and is under the influence of moist air advected from the eastern tropical Pacific Ocean and Gulf of California during the summer. Temperature and precipitation data from Nevada regions 3 and 4 (southern …

East Mortlock : Catchment Appraisal 2002, Don Cummins

Resource management technical reports

This report describes the soils, hydrology, natural vegetation and farming systems of the East Mortlock catchment and provides information on the threats to agriculture, infrastructure and natural resources caused by land degradation.
