Waterfall (erosion) - created from Mind Map cascade of falling water down a vertical drop develops where a band of soft less resistant rock meets a band of harder more resistant rock (limestone and granite) underlying softer rock worn away as water drops onto it

Water on the Land 2 River Discharge - the volume of water flowing in a river Peak discharge - The highest discharge in the time intervalLag time - The delay between peak rainfall and peak dischargeRising limb - The in...

Waterfalls and gorges Waterfalls and Gorges1) Form where a river flows over an area of hard rock followed by an area of softer rock.2)The softer rock is eroded more than the hard rock, creating a step in the river.3)As the water goes over ...

GEO: HOW DO RIVERS SHape the land GEOGRAPHY! How do rivers shape the land? 1. The river erodes downwards as bowders, stones and rock particles are bounced and scraped along the chanel bed.

Rainfall Prolonged rainfall makes the soil become saturated, meaning any further rainfall cannot infiltrate it so runoff is increased. Heavy rainfall means there is a lot of runoff, which increases the discharge quickly New Page

Background to Rivers Terminology for the study of rivers Drainage basin - the area of land drained by a river. Catchment area - the area within the drainage basin. Watershed - the edge of highland surrounding a drainage basin. It marks th...
-
Deforestation Trees intercept rainwater on their leaves, which then evaporates. Trees also store water from the ground. Cutting down trees increases the volume of water that reaches the river. Deforestation can also cause soil eros...

River Management

Deposition This is where the river dumps or leaves behind material that it has been carrying. It deposits larger material first as this is the heaviest to carry. The smaller the load, the further down stream it can be transporte...

Rivers - created from Mind Map Understand how a river erodes, transports and deposits material. Explain the processes of river erosion: hydraulic action, corrasion, corrosion (solution) and attrition Explain the processes of river transportation: t...

Types Of Deposition - Deposition: Is the opposite of erosion, it is where a river lays down or drops the sediment that it is carrying. Rivers carry lots of different sediment, including boulders, cobbles, pebbles, gravel, sand, silt and ...

Waterfalls Waterfall A waterfall is when a river falls over a vertical slope.a waterfall occurs when a band of hard rock lies on top of a band of soft rock. As the water flows over, the soft rock is eroded more quickly than the ...

River processes River Processes Hydraulic action - This is the sheer power of the water as it smashes against the river banks. Air becomes trapped in the cracks in the rock of the river bank and bed and causes the rock to break ...

Untitled V- Shaped valleys A rivers discharge is low in the upper course and so the river only has enough energy to erode downwards. The valley sides are broken down through weathering. The weathered material is transported vi...

Untitled Deltas are criss-crossed by a branching network of distributaries. Overloaded with sediment, deposition in the channel forms bars which causes the channel to split in two. This produces two channels with reduced energ...

Geology When a river is in an area of permeable rock more water will percolate rather than runoff. When it is in an area of impermeable rock water doesn't percolate so there is more runoff. New Page

Levees Levees Levees are raised banks of alluvium found along the banks of some rivers in their old stage. When a river floods it spreads out over the floodplain. As it quickly loses energy it begins to deposit it's loa...

Landforms of erosion Waterfalls A river meets a band of softer, less resistant rock, which is worn away more quickly (through abrasion) and leaves the hard rock on its own.
