Year 12

On Monday we spent a lot of time talking about the factors that affect river discharge, and at storm hydrographs.

The website we looked at with the storm hydrograph stuff was this one

Don't forget please, that you have the Factors Affecting Discharge sheets to complete for tomorrow to give to Mrs Chambers.

Also remember that if you click on the Water on the Land or rivers/hydrographs, etc. labels at the bottom of this post, you will be able to access the posts from this time last year when the current Yr13 were looking at rivers and hydrographs...

Last week...

On Wednesday, we had a look at the anagrams (which, as usual, were not mistake-free, but have now been corrected - I hope!).

We talked about the fact that rivers have ENERGY, and as a result of variations in energy, they can ERODE, TRANSPORT and DEPOSIT material.

Processes of erosion:
- attrition
- abrasion (corrasion)
- hydraulic power/action
- corrosion

We also mentioned VERTICAL, LATERAL and HEADWARD erosion.

Processes of transportation:
- solution
- suspension
- saltation
- traction

We then had a look at the Hjulstrom Curve - some nice bits about that here (don't forget to click Next Page and have a look at all the info on there).

Don't forget about COMPETENCE and CAPACITY as well, when you are thinking about a river's load.

And a nice game of Sink or Swim (thanks to Alan P of GeographyPages, GeographyJazz, Cultcha, etc. fame for the idea!)
