Objectives:

The objective of this subject is to enable students to:

• describe the scale and distribution of water resources and irrigation developments in Australia with particular reference to the Murray Darling Basin and Victorian land use;

• evaluate the water requirements of agricultural enterprises in terms of water quantity, quality and frequency of supply;

• evaluate the nutrient requirements of agricultural water re-use enterprises;

• be aware of the hydrological constraints on water resource development and requirements for harnessing sources of supply;

• apply basic principles of hydraulics to the selection of conveyance systems for water, and wastewater;

• assess hydraulic systems for water and wastewater distribution in terms of efficiency, economy, energy-use and environmental impact;

• be ware of hydrology and nutrient cycles and the influence of these factors on waste management;

• demonstrate an understanding of the physical, chemical and biological characteristics of wastes;

• describe methods for collection, conveyance treatment, disposal and re-use of waste;

• evaluate alternative waste re-use enterprises;

• explain issues associated with the sustainability of enterprises.

Content:

Water supply potential for the development of agricultural enterprises including considerations on quantity and quality. Hydrology and water harvesting systems, sources of water supply including stream diversions, farm dams, irrigation district operation and groundwater utilisation. Basic principles of hydraulics including static and dynamic pressure, flow measurement, pipes, channels, hydraulic structures, pumps and power units. Water distribution systems for farm water supply wastewater re-use and irrigation development, scheduling supply, soil-water interaction, distribution networks, methods of application. Infiltration, seepage, drainage and drainage re-use, surface and sub-surface drainage systems, salinity, conveyance, disposal and re-use of effluent. Water resources management and planning, allocation of resources - selection of systems, cost-benefit analysis. Environmental and energy-use implications of water and wastewater resource utilisation and development. Wastewater and solid waste characteristics, pollution, water treatment.
