How our communities have changed

There are many obvious change that can be seen if you just look around. One main change is the look of buildings. All this modern day, slick, glassy buildings never used to be used in the 90's. And another is the fashion of what people were. But there's also the new developments of malls and car parks and all the renovations to schools and homes. And with the population of Australia growing and leaving, more houses need to be built.

Peer evaluation

Campbell Fisher: Campbell has been a very hard worker throughout the past week, he communicated well with the group and finished his work if not in class, then at home. He always was on time and id say did a very good job.
Nic Kuna: Nic wasn't here at all when me and Campbell was doing the work, he didn't really help out but he did get some information about the natural disaster and if he was here, would have worked well in the group

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.
