Factor
Inuence on ood risk
Precipitation type and
Highly intensive rainfall is likely to produce overland ow and produce a greater ood.
intensity
Low-intensity rainfall is likely to inltrate into the soil and percolate slowly into the rock
thereby reducing the peak of the ood. Precipitation that falls as snow sits on the ground
until it melts. Sudden, rapid melting can cause ooding and lead to high rates of overland
ow, and high peak ows. Also, intense rain compacts the ground and reduces inltration.
Temperature and
Not only does temperature aect the type of precipitation, it also aects the evaporation
evapotranspiration
rate (higher temperatures lead to more evaporation and so less water getting into rivers).
On the other hand, warm air can hold more water so the potential for high peak ows in
hot areas is increased.
Antecedent moisture
If it has been raining previously and the ground is saturated or near saturated, rainfall will
quickly produce overland ow and a high peak ood.

Factor
Inuence on ood risk
Drainage basin size and
Smaller drainage basins respond more quickly to rainfall conditions. For example, the
shape
Boscastle (UK) oods of 2004 drained an area of less than 15 km
2
. This meant that the
peak of the ood occurred soon after the peak of the storm. In contrast, the Mississippi
river is over 3,700 km long – it takes much longer for the lower par t of the river to respond
to an event that might occur in the upper course of the river. Circular basins respond more
quickly than linear basins, where the response is more drawn out.
Drainage density
Basins with a high drainage density – such as urban basins with a network of sewers
and drains – ood very quickly. Networks with a low drainage density have a longer time
before it oods.
Porosity and
Impermeable surfaces cause more water to ow overland. This causes greater peak ows.
impermeability of rocks
Urban areas contain large areas of impermeable surfaces. In contrast, rocks such as chalk
and soils
and gravel are permeable and allow water to inltrate and percolate. This reduces the
peak ow. Sandy soils allow water to inltrate whereas clay is much more impermeable
and causes water to pass overland.
Slopes
Steeper slopes create more overland ow, and higher peak ows.
Vegetation type
Broad-leafed vegetation intercepts more rainfall, especially in summer, and so reduces
the amount of overland ow, peak ow and increases time lag. In winter, deciduous trees
lose their leaves and so intercept less rainfall.
Land use
Land uses which create impermeable surfaces or reduce vegetation cover reduce
interception and increase overland ow. If more drainage channels are built (sewers,
ditches, drains) the water is carried to rivers very quickly. This means that peak ows are
increased and time lags reduced.

The Tragedy of the Commons
is an idea which states that
a commonly held resource
is over-exploited. Nobody
owns the high seas, which
are therefore vulnerable to a
perfectly legal free-for-all. Much
of the overshing occurs in
territorial waters that stretch 12
nautical miles from a country’s
coastline, as well as so-called
exclusive economic zones that
stretch to 200 nautical miles
beyond coastlines, over which a
more limited sovereignty exists.

Tab C.3: Factors aecting glacial abrasion

Relative hardness of par ticles
The most eective abrasion occurs when hard par ticles at the glacier base pass over a
and bedrock
soft bedrock .
Ice thickness
The greater the thickness, the greater the ver tical pressure exer ted on the par ticles of
rock at the glacier base and the more eective abrasion is.
Basal water pressure
Up to a point, presence of water at the glacier base speeds up glacier movement and
leads to an increase in abrasion. However, basal water pressure may “lift” the glacier
above the levels of par ticles at the base, and may reduce abrasion.
Sliding of basal ice
The faster the rate of basal sliding, the greater the rate of abrasion. Ice frozen to the
bedrock cannot erode.
Movement of debris towards
Unless par ticles at the glacier base are constantly renewed, they become polished and
the glacier base
less eective at abrasion. Movement of sediment from the glacier surface, via crevasses,
decelerating ow and plucking brings fresh sediment to the base of the glacier.
Removal of ne debris
Meltwater at the base of the glacier may remove ne debris, therefore leaving larger,
coarser, angular debris in contact with the underlying surface.
Debris par ticle size and shape
Large angular debris abrades much more eciently than smaller, rounder debris.
Presence of debris in
Pure ice is unable to abrade solid rock . The rate of abrasion will increase with debris

Distinguish between the processes of weathering and erosion in arid and
semi-arid areas. Refer to specic landform features in your answer.
2.
Distinguish between the terms exotic, endorheic and ephemeral in the
context of rivers, and give two examples in each case. (Note that making a
distinction means picking out the dierences, not just dening the terms.)

Construction of drainage galleries or adits, from which supplementary borings can be made
Installation of ver tical drains which drain by gravity through horizontal drains and adits, by

Restraining structures
Retaining walls located under unstable ground
Installation of continuous or closely spaced piles, anchored sheet or bored pile walls

Grouting to reduce ingress of groundwater into a slide
Chemical stabilization by liming at the shear surface, by means of lime wells

Natural landscape
Mountains (Nepal); biodiversity (Monteverde cloud forest, Costa Rica); coasts
(Mediterranean); forests (Amazon rainforest); deser ts (Tunisia); polar areas (Iceland); rivers
(Grand Canyon).
Climate
Hot, sunny, dry areas are very attractive to most tourists; seasonality of climate leads to
seasonality of tourism.
Culture
Language, customs, clothing, food, architecture, and theme parks. Examples include
recreation (Paris); religion (Mecca); education (Oxford).
Spor ting events
Events such as the World Cup (Brazil, 2014) and the Olympic Games (London, 2012;
Rio de Janeiro, 2016) lead to a shor t-term boom in tourism.
Government investment
The creation of new resor ts, improved infrastructure and new attractions, for example
and planning

Tble E.12: Barriers to par ticipation in spor t for Muslim women in the UK
Dress code
Spor t facilities/teams and clubs do not always appreciate the need for modest dress.
Facilities
Facilities need to be clean and water available to thoroughly wash after using the toilet.
Provision of a prayer room or quiet area is required as most Muslim women will observe prayer
during specied times in the day.
Lack of role models
The visibility of British BAME will help to break barriers and make the environment more
inclusive.
Parental approval
This is especially impor tant for young women whose parents need to understand the benets
of spor t to allow them to encourage out-of-school activities and feel comfor table that the
environment will be safe.
Transpor t
It is often more appropriate for women to access services locally as most will not have access
to transpor t and will be reluctant to use public transpor t in the evening if they are on their own.
Social side
The traditional social side of spor t does not link in with the religious requirements of Muslim
women who do not drink alcohol and will not par take in activity that may be considered
inappropriate and incompatible with their beliefs.
Communication
Language is often a barrier as being unable to communicate causes anxiety and uncer tainty
around how to approach and access services.
Lack of women-only
Most Muslim women will only play in a female-only environment.
sessions
Childcare
Traditionally this is the sole responsibility of women. Although attitudes are changing, provision
of crèche facilities will allow greater access for women with children.
Socio-economic
Statistically BAME people earn less than their white counterpar ts which limits access,
dierence
par ticularly for women who often give nancial priority to their families.
Time
Other commitments such as childcare and running the home take priority and spor ts organizers
should consult with the community regarding the timetabling of events.
Employment
More needs to be done to encourage young women to access employment within the sector to
help break down barriers and act as a resource to equip other sta with knowledge about the
communities they serve. This includes the admin side of spor t.
Environment
Safety, lighting and security are impor tant to prevent racially motivated incidents.
Information
Information should be made available in other languages and services marketed in appropriate
places, such as mosques and schools, to ensure women become aware of what is on oer.
