|
|
Velocity
|
the speed of water meters/sec
|
|
Risk |
likelihood of hazard occurring * severity of the hazard
|
|
3 elements to a risk assessment
|
a) Identifying the risks/ hazards b) minimising the risks c) minimising the on going risks` |
|
Risk management of drowning |
Do not go into the river any deeper than welly height
|
|
Risk management of gorse and ticks |
wear long trousers and sleeves to avoid being scratched and to reduce risk of being bitten.
|
|

|
What's wind speed (m/s) measured by?
|
anemometer
|
|
What is the method of an anemometer? |
Wind speed recorded by noting the number of revolutions from the "cup counter". Difference from the day before can be calculated. |
|
What equipment is used to measure wind direction? |
Wind vane. Made up of an arrow mounted on top of a spindle, allowing the arrow to move with the wind. the arrow always points in the direction in which the wind is blowing. |
|
What method is used to measure wind direction?
|
ideally measured In a large open space away from buildings. can either be hand held or ideally mounted on a roof top or mast 10m above the ground. |
|
What equipment is used to measure rainfall?
|
Rain guage
|
|
What method should be used to measure rainfall?
|
Simplest rain guage is basically a funnel mounted on a spike which can be inserted into the ground.
|
|
What method should be used to measure cloud cover?
|
Cloud amount is measured by dividing the sky up into 8s, known as oktas, and estimating how much is covered by cloud. 0 oktas = no cloud 8 oktas = all cloud |
|
What equipment should be used to measure Atmospheric pressure (millibars or mb)?
|
Barometer
|
|
What method should be used to measure atmospheric pressure?
|
The pressure should be recorded at the same time each day (9am). First gently tap the front of the Barometer, making a note of weather the needle is falling or rising, this is pressure tendency. keep tapping until the needle stops moving. read off the value on the scale. |
|
What equipment should be used to measure temperature (degrees C)?
|
Thermometer, protected by a Stevenson screen (a white louvered box which is designed to protect thermometers against direct sunlight and wind)
|
|
What method should be used to measure temperature?
|
The Stevenson screen should be mounted 1.25m above the ground away from large obstructions. |
|
What equipment should be used to measure sunshine hours?
|
a sunshine recorder.
|
|
graphical skills
|
Compiling graphs and flow lines; using proportional symbols; annotating maps; diagrams and photographs. |
|
Map skills |
With particular reference to maps (including digital maps): using grid references; understanding scales; recognising symbols; identifying landforms and human features of the landscape. |
|
Photo-interpretation skills
|
Reading vertical and oblique aerial photographs and satellite images, including GIS. |
|
Sketching skills |
Communicating ideas through simple sketch maps and field sketches. |
|
Spatial awareness |
Identifying the relative locations and relationships between features. |
|
Analysis of findings |
Reviewing and interpreting quantitative and qualitative information using appropriate media |
|
Use of statistical skills |
Simple descriptive statistics, such as lines of best fit, mean, medians, modes etc. |
|
Conflict resolution skills
|
Identifying the views of stakeholders, recognising that stakeholders may have strongly different attitudes and feelings towards a particular issue. |
|
Evaluation of findings |
|
|
Quantitative data |
information about quantities; that is, information that can be measured and written down with numbers
|
|
Qualitative data
|
typically descriptive data and as such is harder to analyze than quantitative data. Qualitative research is useful for studies at the individual level, and to find out, in depth, the ways in which people think or feel (e.g. case studies).
|
|
What equipment is used to measure the roundness of bed load
|
Calliper (unit is power's scale) |
