A full set of definitions of ‘drought’ can be found in Hounam, et. al., (1975). Standard definitions of drought refer to the occurrence of water within the hydrological cycle. They include;

  • meteorological drought: a combination of climate features that lead to a deficiency of water in the climate phase of the hydrological cycle.
  • agricultural drought: deficiencies of water at the crop water/ soil moisture level.
  • hydrological drought: deficiencies in streamflow or groundwater resources.
Water supply droughts are combinations of meteorological, hydrological and storage water deficiencies, and therefore, depend on the circumstances surrounding the provision of water supply. Meteorological, agricultural and hydrological droughts are often out of phase with each other (Klemes, 1987). The sequence is generally meteorological, followed by agricultural and then hydrological. Therefore, in terms of water supply, drought is more complex than a simple rainfall deficiency. Water supplies have been established to provide protection against rainfall deficiency periods but there is an element of risk of not being able to provide supply on a permanent basis.

In the past, drought planning in the region, and in Australia as a whole, has been reactive, resulting in inefficient allocation of water. Within the water sector, planning for short-term response to drought had previously involved water authorities placing ad hoc restrictions on water usage. Today, adequate planning necessitates detailing both short and long-term responses to meteorological, agricultural and hydrological drought. Such planning would be activated by drought indices (see Srikanthan and Stewart (1992) for particular indices).

Various storage and usage options exist to address the threat of drought in Victorian regions. They include:
  • Surface water storage: on and off-stream storages.
  • Groundwater (see Bartley, et. al., 1992).
  • Reuse: treated sewage and grey water.
  • Stormwater: for treatment and supply by water authorities.
  • Networking systems: transfers of water within and between basins which were previously independent harvesting and supply systems.
  • Rainwater tanks
  • Dead storage pumping: water contained below conventional offtake levels.
  • Water cartage: although this would be adopted only in emergency situations, which should not occur under adequate drought planning.
  • Cloud seeding: a potential long-term measure, previously undertaken by the CSIRO to stimulate rainfall from suitable cloud formations.

Relevant DPI Landcare and Agriculture Notes

Drought reserve dams"Drought proofing" is a set of strategies and works for enabling a property cope with extended dry periods. These include vegetation protection, stocking strategies, use of stock containment areas, fodder reserves and water reserves.

Paddock protection and stock management during dry timesThe management of paddocks and stock during dry times requires considerable care to avoid degradation of soil and water, damage to plants or seeds and long term financial loses. We wish to avoid the degradation of 1982/83 though appropriate management. Paddocks should remain in such a condition that soil structure and fertility are protected and ready to respond to the return of wet weather.

How long will my dam water last?This Landcare note is to help land managers calculate water demands being made by livestock on existing water storages, especially during drought periods.

Hints on feeding grain to cattleThere are three situations where grain might be fed to cattle - as a drought ration, as a supplement to grazing or in lotfeeding. In all cases care must be taken, especially in the introduction or conditioning of cattle to grain feeding.

Paddock protection and stock management during dry timesThe management of paddocks and stock during dry periodst requires consideration of a number of factors to avoid degradation of soil and water, and damage to plants or seeds.
