| What is Attrition? | This is the beating action of erosion, when the load bumps into each other |
| What is Discharge? | Volume of water in a river at a given time usually measured in cumecs. |
| What is a Drainage Basin? | An area of land drained by a river and its tributaries. |
| What is Evaporation? | This is an output from the system. it is the loss of moisture directly from the rivers and lakes. |
| What is a Flood Plain? | A flat part of land where water expands when a river floods. |
| What is meant by Ground water flow? | This is the sideways movement of water through the rock towards the river. |
| What is Hydraulic action? | This process involves the force of water against the bed and banks. |
| What is Infiltration? | This is the downward movement of water through tiny pores in the soil. |
| What is interception? | This is when rain is caught by trees and plants and cannot reach the ground. It is stored on the leaves. |
| What is meant by a Levees? | A natural embankment on the side of a river channel. |
| What is Load? | Material of any sort or size which is being carried by the river. |
| What is a Meander? | This is a natural occurring bend in the river. |
| What is meant by an Ox-Bow lake? | Where a meander has been cut off from the mainstream river. |
| What is Percolation? | This is the downwards movement of water into rock. |
| What is meant by precipitation? | This is how water enters the system in the form of rain,snow or hail. |
| What is saltation? | Sand size particles are bounced along the river bed by the flow of the rivers water. |
| What is meant by solution? | Some minerals dissolve in the rivers water such as calcium carbonate. This requires very little energy. |
| What is Surface Runoff? | This is water that runs river the surface of the ground towards the river because the soil is saturated. |
| What is suspension? | Fine clay and sand particles are carried along within the water even at low discharges. |
| What is through flow? | This is the sideways movement of the water through the soil towards the river. |
| What is Traction? | Boulders and pebbles are rolled along the river bed at times of high discharge. |
| What is meant by Transpiration? | This is one of the ways the water is lost from the system, moisture is lost directly through the process of vegetation. |
| What is groundwater store? | This is water stored deep underground in rocks. |
| What is Erosion? | The process of wearing away a material. |
| What is Transportation? | The process of carrying an type of material. |
| What is Deposition? | The process of dropping away material. |
| What is Corrosion? | The chemical action of the river water. he acids in the water slowly dissolve rocks such as limestone. |
| What is meant by the term Thalweg? | This is the fastest point of the river. |
