Database Entry Details

Please fill in as many of these fields as you can to make your entry in the Urban Groundwater Database. At least the first four fields are required to enter a new Town or City into the Database successfully. Sample database entries for Perth, Western Australia, are provided as a guide. Just delete them and enter your own information!

Name of Town or City		Required!
Name of State or Province		Required!
Name of Country		Required!

The following boxes allow you to enter textual data on your new Town or City. Please keep your entries in each field to under 500 words. URL and HTML tags are allowed but should not link to commercial or profit-related sites.

Description of City or Town:	Perth has a population of about 1 million and is a commercial centre with a very small industrial base. It is one of the most rapidly developing cities in Australia, and the population is expected to double by 2020. About 60% of the city is sewered and the remainder is being progressively connected to sewer. The population density is low and the city covers an area of more than 700 km2.
Description of Climate:	Mediterranean climate (winter rain, summer drought). The average annual rainfall is about 800 mm and the potential evaporation is 2500 mm. On average, evaporation exceeds rainfall for 8 months of the year.
Description of Basic Hydrogeology:	Perth is located in a sedimentary basin and is underlain by porous medium aquifers. A sandy surficial aquifer underlies much of the city and this in turn is underlain by confined sandstone aquifers. The surficial aquifer is recharged by rainfall and deeper aquifers by leakage. On average, the recharge rate in undeveloped areas is about 15-25 % of annual rainfall and up to 35% of rainfall in urban areas. Groundwater discharges to the ocean, wetlands and the Swan estuary.
Description of Water Use:	Groundwater provides about 40% of Perth's potable supply and 70% of the city's total water usage. Groundwater is widely tapped for the irrigation of gardens and parks and there are about 100 000 irrigation bores in the Perth metropolitan area.
Description of Groundwater Issues:	The maintenance of high quality potable groundwater in close proximity to Perth is probably the most pressing issue currently facing regulators. Other issues include minimising the contamination of groundwater by nitrate to prevent the eutrophication of waterways in groundwater discharge zones, and minimising the drawdown of the watertable in abstraction areas to protect native phreatophytic vegetation.
Description of Groundwater Problems:	In urban areas, water supply bores are commonly affected by the products of urbanisation. S pecific problems include....x, y, and z. Locally groundwater concentrations of x, y, and z are.....etc.. The problems are most severe in... Additional problems include the contamination of water supply bores locally by saltwater intrusion in coastal areas, and the discharge of nutrients by groundwater to wetlands and coastal environments.
Description of Solutions:	Use of groundwater protection zones in undeveloped areas to protect potable supplies.
