1. A flood is water that inundates land which is normally dry.
2. Flash flooding is when  rivers and streams are unable to cope with the sudden volume of water caused by heavy downpour. Urban areas are especially vulnerable due to the drainage systems which can become overloaded, resulting in flooding.
3. The inland rivers generally cover thousands of square kilometres in water lasting weeks, whereas the Coastal River systems tend to be short and fast flowing, generally lasting from a few hours to a few days.
4. Flooding affects farms, when it comes to stock and crops, but it also destroys infrastructures like roads and railway lines.
5. The town of Katherine received 374 millimetres of rain while the surrounding catchment area received between 400 and 500 millimetres over a short period of time (48 hours). The catchment was already saturated from previous weeks rainfall so most of the new rainfall ran off into the river which quickly caused a flood. The reason it was considered worse than the 2006 flood was because the 1998 flood peaked at 20.3 Metres above its usual flow level, where in 2006 it only peaked at 19 Metres.
6.
Economic: The flood would of impacted the Economy in Katherine due to the damage caused by the flooding, which cost a lot of money in repair costs.
Social: The social impact was bad because it caused 500 businesses and 1170 homes to be evacuated and Four people were killed as well as flooding the Whole town.
Environmental: The flooding can drown plants and crops and livestock.
7.
b) The Coastal gradient was a lot smaller than compared to the Inland River Catchment Gradient.
c) The gradient in a Coast area is a lot smaller so the water hasn't got that much land to pass through before it is cleared, compared to the inland river systems which have thousands of kilometres to pass through.
10. I had just moved to the town called Katherine, I decided to buy the local Motel because it seemed to be just about the only place tourists would be able to stay meaning it would be money well spent, if not profitable. Little did I know that it was in one of the worse areas if a flood were to occur. It was almost February of 1998, and one of the worst floods I've ever seen hit. 2 Metres of water came rushing through taking cars with it. As soon as I saw the water I knew the damage would be devastation. We moved to the highest floor in the motel avoiding the water, but we could hear it as it seeped through the doors and open windows flooding the motel below us. We came outside to see people crying at the loss of their possessions and one person actually asking why the floods had taken his son. It was truly one of the worse days that Katherine had seen.

2.5

1. A tropical cyclone is a storm system characterized by a large low-pressure centre and numerous thunderstorms that produce strong winds and heavy rain.

2. They occur anywhere in the tropics.

3. Queensland, Northern Territory and North Western Australia.

4. out of the 10 that form in the Australian region 6 of them cross the coastline.

7. The eye is middle of the cyclone and it is calm and has clear sky.

2.3

1.       1.Hail which is 2 cm in diameter, winds of 90 kms, flash flooding and tornadoes

2.       2.The potential to destroy houses and property

3.       3.When humid air gets pushed upward into the atmosphere by converging surface winds, the air rises, moisture condenses and releases heat energy called latent heat which causes buoyment allowing it to rise further into the atmosphere and freezes which causes crystals to drop and create hail.

4.      4. Its heat energy and its one of the steps that create hail

5.       5.Up in the higher atmosphere where its colder and water particles can freeze

6.       6.It’s more likely for a tornado to form in the ocean or on a river since its colder

7.       7.The bureau of meteorology by the study of synoptic charts and weather conditions

8.       8.Because people can never judge how big or wild it will be and there’s no real evidence that it will strike were and when its predicted

9.       9.A) at 1:10 pm b) Maitland, Raymond Terrance and Newcastle, Lemon Tree Passage and Nelson’s Bay c) 2:10 pm  d) to turn off your laptops, to get away from the windows, to move all loose objects and hide under the desks until storm passes or you are instructed to leave.

Weather journals

Today is the 4th of may and we went outside to see what the weather was like. It was cool and crisp, with a nice, slight cool breeze on the early autumns morning, with a slight slight chance of showers because the clouds in the sky look a little grey (altos stratus) even though there aren't that many, I wouldn't get worried about rain today but i would be a little weary of the weather.

Deadly Storms in the US

• Deadly storms had hit around the south east of the US.
• 318 people died in deadly storms
• 33 in Mississippi
• 228 in Alabama
• Tennessee 17
• A high risk storm it was called
• A rare high risk threat area has been issued for far northwestern Georgia which means a major severe weather outbreak is anticipated with a concentration of tornadoes and straight-line wind gusts of 80 mph
• Being called supercell thunder storm, the strongest kind of stroms.
• The Storm Prediction Center has issued 82 high risk areas since 1984. Today is the 3rd one this April…and this year.
