Lort And Young Rivers Catchment : Catchment Appraisal 2001, Jamie Bowyer, Esperance Catchment Support Team (Wa)
Resource management technical reports
Using the Rapid Catchment Appraisal process, this report summarises current information for the Lort and Young Rivers Catchment, 75 kilometres west of Esperance in Western Australia. The Rapid Catchment Appraisal (RCA) process is one of the processes included in the strategy to tackle salinity and its management in Western Australia. The RCA process provides a 'snap shot' of information on the risk and impact to agricultural production and natural resources within regional geographic catchments.

Groundwater Study Of The Mukinbudin Townsite, F Lewis
Resource management technical reports
A groundwater study was carried out in the townsite of Mukinbudin, Western Australia. The town does not currently have a salinity problem, but the future risk is not known. It aimed to accelerate the implementation of effective salinity management options. The study consisted of a drilling investigation, installation of a piezometer network, groundwater flow modelling and a flood risk analysis.

Hydrogeological Study Of The Dongolocking Reserves, Dumbleyung, Western Australia, Ben Whitfield
Resource management technical reports
The aims of the hydrogeological study were to assess the characteristics of aquifers within the weathered zone, throughout the Dongolocking Reserves and in the surrounding farmland; provide baseline data on root zone salt store (EM38) and vertical distribution of stored salts (EM38) through the use of ground-based geophysical techniques; identify remnant bush at risk of salinisation; suggest management options to address any observed salinity problems; provide a groundwater monitoring network.

The Rural Towns Program : Groundwater Modelling : The Merredin Catchment, J Matta
The Rural Towns Program : Groundwater Modelling : The Merredin Catchment, J Matta
Resource management technical reports
Agriculture Western Australia (Agwest), as part of the Rural Towns Program, was engaged to test the application of a groundwater model for potential future management options against salinity for the Merredin townsite. This report illustrates some of the options that could be implemented to achieve the objective of salinity management.
Salinity And Hydrology Of The Fence Road Catchment : A Focus Catchment Of The Blackwood Basin, Ben Whitfield
Salinity And Hydrology Of The Fence Road Catchment : A Focus Catchment Of The Blackwood Basin, Ben Whitfield
Resource management technical reports
It is the clearing of native vegetation and replacement with lower water-use annual crops and pastures that is responsible for the developing salinity problem. Traditional farming practices have led to increased recharge to the groundwater systems resulting in increased storage and/or greater areas or rates of discharge. Groundwater monitoring has revealed variable rates of rise throughout the Fence Road catchment, from static to 0.6 metres per year, in a period of average to below average rainfall.
Observations On Groundwater Recharge In The Westdale Catchment, M F. Lewis, C E. Mcconnell
Observations On Groundwater Recharge In The Westdale Catchment, M F. Lewis, C E. Mcconnell
Resource management technical reports
A study of the role of groundwater carriers and barriers in controlling salinity was carried out in the Westdale Catchment by Lewis and McConnell (in preparation). Although that study was primarily concerned with groundwater flow and discharge processes, the data collected also provided rudimentary information on the timing of groundwater recharge events and their distribution across the landscape.
Groundwater Investigations In The Jerramungup Shire, S B. Martin
Groundwater Investigations In The Jerramungup Shire, S B. Martin
Resource management technical reports
Drilling was carried out with a dry rotary auger rig, with a depth limit of 31 m for the first 28 piezometers and 40 m thereafter. Farmers assisted in the site selection and construction of the piezometers in most cases and will in the future be responsible for monitoring their piezometer(s) regularly. The average depth to bedrock was 18 m and the average dept to groundwater was 9 m, with an average salinity level of 3600 mS/m. The average total salt storage was approximately 2800 tonnes per hectare.

Preliminary Groundwater And Salinity Investigation In The Eastern Wheatbelt. 4. Kitto's Hillslope, Tammin - 1985-90, Richard J. George Dr
Resource management technical reports
The investigation revealed that a deep, brackish to saline groundwater system and dolerite dyke, contained within the saprolite were responsible for the secondary salinity; the annual discharge of water and salt at the seep from the damp groundwater system was about 2800 kL and 17 tonnes respectively; and the water-tables were not rising and that the most appropriate management of the site was to plant salt tolerant forage plants in combination with trees.
Preliminary Groundwater And Salinity Investigation In The Eastern Wheatbelt. 1. Brennand's Catchment, Richard J. George Dr, P W C Frantom
Preliminary Groundwater And Salinity Investigation In The Eastern Wheatbelt. 1. Brennand's Catchment, Richard J. George Dr, P W C Frantom
Resource management technical reports
Groundwaters were found to be 10 m below the floor of the ancestral playa lake in Brennand's catchment. They were extremely saline. A groundwater flow system was not established on much of the catchment. Flow was observed to be occurring from recharge areas near the playa lakes towards the midslopes of the catchment. Flow was apparently restricted from leaving Brennand's catchment because of obstruction to groundwaters created by dolerite dykes.

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.

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.
