Case Study 1 Bostcastle, Cornwall 2004 MEDC
Thundery Downpours developed in SW England as a result of an intensive low pressure weather where 200mm fell per 24 hours. Antecedant Rainfall; ground was already saturated, reducing further infiltration. 60 properties were submerged.70/80 cars swept

Case Study 2 Bangladesh 2004 LEDC
lies on Delta land of 3 major rivers: Ganges, Brahmaputra and Megna: all from Himalayas. Cyclones= winds, prec and storms. Increasing D of rivers = FLOOD. +Urbanisation in Dhaka by 1m.
2 of 35
Management and effects
Foreign aid t finance large Dev. Projects. UN: Disaster management coordintaing activities of agencies. +5yr plan from world bank. 36million homeless, death toll to 800 + cholera deaths. $2.2 billion damage cost

Population 1: China
1979: 1 child policy. Population: 1.3 billion. largest in the world. Benefits given to those who obeyed, and to the ones who didn´t, benefits were lost and salary was fined.
4 of 35
Effects: Positive and Negative
Woman were forced to have abortions as late as the 9th month pregnancy. Gov had power over people´s private lives. Sons preferred, females disowned or allowed to die. Benefits: Avoided famine, optimum pop achieved. Inc.Standard of living and Decpov.
5 of 35
Population 2: France
Pronatal policy incentives. 3 years paid parental leave for either parent. Full time schooling at 3, fully paid by gov. Daycare for under 3: subsidized by gov. RESULT. Favourable age structure and Dep. Ratio

International Migration 1: Poland to UK
In poland: Huge Unemployment and love average wages. In UK: Ease of Migration, +work and higher wages. Good exchange rates
7 of 35
Impacts, Poland and UK
Poland: Pop and BR dec. Shortage of workers. $ boosted by money sent home. In UK: Inc pop. Diverse and cultural, however Racism & prejudice. New shops and businesses. Dec Jobs. Inc Competition.

Forced Migration 1 : N Africa to EU (Spain)
8th August 2011. "Salvamento Marítimo" intercepted "patera" boat, with 58 people from Saharegan origins, 10miles away from Alborán. (54 men, 3 woman, 1 child)
9 of 35
General statistics
1432 immigrants in 60 pateras have been able to cross the Gibraltar channel into Almeria, Granada. Cádiz, Huelva and Málaga since Jan 1. Major imm. Index: in Granada; 812 people in 18 boats. Almeria: 456.

Drainage Basins and Rivers: General. Factors affecting SH
(10) Temp. Basin Shape. Prec (3) Antecedant RF, Soils (2) Rock type (2), Veg, Land use, Urbanisation: - Removal of topsoil withEarthmoving machinery, Roads: inc imp surface A. Building of Drains
11 of 35
Erosion processes:
Abrasion: Scraping, scuring and Rubbing actions of materials carried along river.
12 of 35
Hydraulic Action:
Sheer power of H20 moving loose unconsolidated material because of frictional drag.
13 of 35
Corrosion
Minerals in rock dissolve by weak acids in the river H20 and carried away in solution.
14 of 35
Attrition:
Dec. size of ragmen's and particles within river due to processes above. Strike one another.
15 of 35
Lateral Erosion
Middle and low reaches: valley floor lies closer to sea level, widening the valley = meanders
16 of 35
Rapids
Found where there is a sudden Inc. in the slope of channel H20 + turbulent= inc. erosive power.
17 of 35
Waterfall Case Study1:
Whin Sil: overlying sandstones, limestones and coal seams: erode quickly overhand. Result: 22m Tallest in England.
18 of 35
Vertical Erosion
River cutting down to it´s level (sea) V=high. river cuts down into its valley mainly by abrasion and hydraulic action= steep sided valleys formed.
19 of 35
Factors affecting V shaped Valleys:
Climate: Suffiecient RF. Geology: Type of Rock; eg.Limestone = Steeper sides. Vegetation: +Veg= binding soil together: +stable steep valley sides
20 of 35
Braiding
Rivers forced to split into several channels separated by islands: Large loads of sand and gravel occur when river varies discharge. River is choked with several sandbars
21 of 35
Levées:
Middle and lower reaches: At risk from flooding in times of high Discharge. V of H20 falls =deposition:coarsest material deposits first. Subsequent floods inc size of these banks and further deposition swell.
22 of 35
Floodplains:
Resultant of both erosion and deposition: Flat areas of land at either side of river: form the valley floor in the middle; composed of Alluvium; Silts and clays.
23 of 35
Deltas:
Deposition process, at location of the mouth. Form when rate of deposition exceeds rate of sediment removal. (3) Arcuate: Nile: Curving shoreline. Cuspate: Mississippi Cup or Tooth shape and Bird´s foot.
24 of 35
Population1:
Net migraton: Dif between # of IN-migrants and # of OUT-migrants.
25 of 35
Causes for Pop Growth
Health: Disease control, Birth control measures, IMR, Diet, medical supply and sanitation.
26 of 35
Education
Inc. literacy levels
27 of 35
Social provision:
Care of elderly
28 of 35
Env. factors and cultural
hazard frequency, env conditions and Religion
29 of 35
Demographic Transition Model:
1.High stationary: Tribes 2. Early expanding: Ethiopia, Sri Lanka. 3. Late expanding; China, Australia 4.Low stationary: USA, Japan
30 of 35
Reasons for migration:
Environmental, Social, Political and Economical
31 of 35
Overpopulation 1: Haiti:
8.1million people and doubled in less than 50 yrs. Pop density: 295/km2. Poorest country in W.hemisphere.Nat Disasters: Quakes and floods. GDP: 1,500. 80%absolute poverty. Spreading diseases:HIV/AIDS30,000: HIghest in Latin Am and Caribbean.
32 of 35
Solutions:
Sun oven: Dec Deforestation =Cheap. Inc Afforestation: inc Soil fertility and dec. Land flow. SHOW POP PYRAMID.
33 of 35
Urbanisation:
Rural Pop. Declining: Consequences:1.Elderly left behind 2.Isolation. Rural to urban inc: 1. New housing estates. 2. +traffic 3.Conflicts and values
34 of 35
Urband to Rural Case study 1: Dorset, isle of Purbeck
Total pop: 44,146 people. What happened: Isolation conflicts. Elderly left no activity. Deprivation. Dorm Villages, 2nd hand commutes. pollution. What is not there: NO private schools, offices, libraries, healthcare. transport.
