791-012 Water Resources & Waste Water Management

Soil and Water Resource Conservation.

The objective of this subject is to enable students to:

• 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 aware 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; and

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

The content includes 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; water distribution systems for farm water supply wastewater re-use and irrigation development, scheduling supply, soil-water interaction, distribution networks, methods of application; water resources management and planning, allocation of resources; environmental and energy-use implications of water and wastewater resource utilisation and development; and wastewater and solid waste characteristics, pollution, water treatment.

2-hour examination (60%); project report of 3000 words (40%).
