Flooding notes

Today we are finishing our notes on flooding. Then we will be talking about what Manitoba government is doing to prevent flooding.

Discharge
The volume of the water that flows past a particular point during a set amount of time.
How much water is moving compared to regular times.

Sea level
The height of the water at a particular point compared to the standard sea level.
How high/deep the water is compared to regular times.

Tracking the flood
Hydrograph is a graph used to show changes in a river's discharge over time.
Can help predict how future floods will behave(amount of water,length,etc.)
The area downstream will flood for longer period of time.
It takes longer for all of the water to flow past the end point
   -small stream/river are affected faster then larger bodies of water
   - changes are noticeably faster since they are small to begin with

Flod notes

Drainage basins

• the area where all the precipitation accumulates is called a drainage basin

• the boundary in between basins is called a drainage divide

• rain falling on one side of the divide goes into one basin, where the rain falling on the opposite side goes into a different basin

• anytime there is t much precipitation in one drainage basin then there well be a flood

• can result from: melting snow, hail, rain water, ice storm or any other combination  

Tracking the Flood

• organisations track early flooding to help plan

• what dams or flood ways need to be built

• what areas are not good for building

• what areas need food relief credits ($)

pros and cons of flooding
pros                                                            cons
-water for people who need it                    -people can die
-give soil different nutrients                         -loss of land
-more fish                                                   -loss of crops
-more beavers                                             -trees can die
-                                                                  -take nutrients out of soil
-                                                                  -loss of houses

drainage basins
-land is not flat there is always some chang in the land
  -how high or low the land is.
precipitation will flow from highest elevation to the lowest elevation

RUNNING OUT OF FRESH WATER

    Today in science we continued on are notes about how much water we have, use, what country has the most, and the country that has the least. 
    71% of the world is covered by water, while 97.5% is salt water and 2.5% is fresh drinking water. if we run out of fresh water we will need to pay to disstile the salt water too fresh water to drink.
    The top 5 countres with the highest mount of fresh water is -Brazil -Russia -Canada -USA -Indonesia, the 5 countres with least amount of water is -Bahrain -Qutur -Malta -Maldives - Nevis. The average person drinks and uses about 80 to a 100 gallons of water. And that's what we leart in are notes about fresh water.

Ocean Tides

What Are Tides?

~The rise & fall of ocean water.
            
                -Caused by gravitational activity

~The highest tide movements appen when the earth, moon and sun line up

                 -Highest gravitational pull
                
                 -Called spring tides
                
                 -Only on a full moon or new moon


~The smallest tide movements happen when the sun and the moon are at right angles to one
another

                  -Little change
                 
                  -Called neap tides

New Unit!

    Today in science we started a intro about are new unit the Water System. In this unit we are going to be learning about what happens to rain when it falls, were does water in your taps come from and will earth one day run out of water.

 

This is a video we watched today it shows how much water is needed to make one burger.

 

 

This is a good pictue we used to show us how the water cycle works.
