Geoscience Australia:. The Australian Flood Risk Information Portal the portal enables flood information, currently held by different sources, to be accessible from a single online location.

The portal includes a database of flood study information and metadata the Australian Flood Studies Database. The portal provides access to authoritative flood maps and flood studies, as well as information about surface water observations derived from the analysis of satellite imagery. The portal incorporates tools that enable users to search, display and retrieve information. The data management tools and standards that have been developed for the portal will enable data custodians to standardise their data and upload it to the portal, or to make compliant data accessible via web services.

The information in the portal has been provided by local, state and territories governments. Contributing more flood studies will significantly enhance its value. It will improve our understanding of flood behaviour on a regional scale, which is essential because floods do not respect jurisdictional boundaries.

The Australian Flood Risk Information Portal the portal hosts data and tools that allow public discovery, visualisation and retrieval of flood studies, flood maps, satellite derived water observations and other related information from a central location. The portal is focussed on providing access to flood information from authoritative sources.

The main catalogue of information available through the portal is the Australian Flood Studies Database. Information in the portal can be searched and accessed by all users, but only registered users can add flood studies and associated maps to the database. A registered user would typically have been responsible for the creation or publication of flood hazard information, and might include state authorities, local councils, consultants and authorised data custodians.

Data custodians can share their flood study information with other users either by adding data directly into the portal's data catalogue, the Australian Flood Studies Database, or via web services. Data Entry Information Information on entering data into the portal, including how to login or register to use the Data Entry Application.

Portal Framework Describes the overarching approach taken in developing the portal, as well as the agreed principles and benefits supporting the portal. Log in. This review highlighted the lack of consistency across the country in the way flood risk information was collected and made available to users.

The review also recognised the need for consumers to be aware of the natural disaster risks they may face, as well as the benefits of making flood risk information more readily accessible. In response to these findings, the Government established the National Flood Risk Information Project NFRIP with the aim of improving the quality, availability and accessibility of flood information across Australia and, in doing so, raise community awareness of flood risks.

This four year project commenced on 1 July and delivered three products; the portal, Water Observations from Space and the Australian Rainfall and Runoff Guidelines. The portal is used by engineers, insurers and planners to find out what flood mapping information exists, and where, so they can better understand risks. Several different weather conditions can cause extreme rainfall in a region. Tropical cyclones form in some tropical and subtropical areas, usually in the summer and fall.

When they appear in the Atlantic Ocean or the northwest part of the Pacific Ocean and reach a certain intensity, they are called hurricanes. Tropical cyclones can produce huge amounts of rain, causing flooding and flash flooding once the storm reaches land. They can also send a rush of water from the ocean onto coastlines in an event called a storm surge, which floods low-lying areas.

Another phenomenon that can cause extreme rainfall is called an atmospheric river. Current Hazards. Local Regional National. Rivers and Lakes. Climate and Past Weather.

Pollutants and man-made objects tend to contaminate locales with various harmful materials- such as shattered debris and untreated sewage that can directly contribute to diseases in the general area.

Unfortunately there is no magical cure-all for floods. However, contributing and helping to alleviate climate change can aid future generations. Consistent preparation is something that can be done regarding floods that can effect the here and now. Ensuring you have a bug out bag so you can evacuate in a moments notice. Once the water level starts rising, move furniture and other important possessions to the upper levels of your home. If you notice the telltale signs of flooding, consider relocating your family, pets, and livestock somewhere safe.

For those living in a flood-prone area, it is wise to get insurance as it can help you rebuild any damages your home incurs. In the event your property is damaged or destroyed, you should hire a reputable contractor to perform water damage restoration to your residence or business. Having an understanding of how floods form is a key factor leading to successful preparation and survival.

As a rule-of-thumb, you should remember that if it seems dangerous you should evacuate as soon as possible, and secure all things necessary for a rebuild. If your property is affected by a flood, it is difficult to bounce back. Which is why you need a team that can help get you rebuilt, and back up and running as soon as possible.
