St Ivo School Geography Department - GCSE REVISION Yr 11 - Watery World www.geobytesgcse.wordpress.com The Hydrological cycle is a closed system with a fixed amount of water cycling between the air, land and sea, in one of three stages, liquid, gas or solid. Fold along here Explain what is meant by the Hydrological cycle. www.geobytesgcse.wordpress.com St Ivo School Geography Department - GCSE REVISION Yr 11 - Watery World www.geobytesgcse.wordpress.com The drainage basin is an open system as there are losses and gains to the system. The amount of water in the system at anyone time varies with inputs and outputs from the system. Fold along here The Drainage basin system is an open system – what does…show more content…
www.geobytesgcse.wordpress.com St Ivo School Geography Department - GCSE REVISION East Anglia’s Water supply is from two main sources: Yr 11 - Watery World www.geobytesgcse.wordpress.com Fold along here Outline the main sources of water supply for your local area N/W of E Anglia – Anglian Water – water coming from – Rivers (5%); Reservoirs (50%) – e.g. Grafham and Rutland – found here as impermeable bedrock and Boreholes (45%) – in the South and East of the Region – including St Ives – Cambridge Water Company – with 95% of the water from boreholes in aquifers (large areas of chalk) www.geobytesgcse.wordpress.com St Ivo School Geography Department - GCSE REVISION Yr 11 - Watery World www.geobytesgcse.wordpress.com Fold along here Describe the variations in water supply across the world. - Areas of surplus are found mainly in the northern hemisphere (e.g. N America, N Europe and Russia - Areas of physical scarcity are mainly in the Middle East and North Africa - Areas of economic scarcity where people cannot afford water even when available are mainly in the southern hemisphere – e.g. S American and Africa…show more content…
Leakage 2. Rainfall and Population Imbalance (uneven distribution) 3. Variability in Rainfall 4. Seasonality – rainfall imbalance 5. Pollution www.geobytesgcse.wordpress.com 1. Explain the following water supply pro blems: Yr 11 - Watery World www.geobytesgcse.wordpress.com 2. Fold along here 1. Leakage 2. Uneven Rainfall distribution in the UK 1. Leakage – loss of water through broken pipes is an increasing problem – in areas such as London – over 50% of pipes are over 100 – ageing pipes leak and traffic and freezing weather damage pipes further. Daily cost to economy of water leakage in UK - £1,500,000 - £3.6 mill. Uneven Rainfall and Population Distribution in the UK. 1/3 of population live in SE – but driest part of the UK (600-800mm p.a.) – in mountainous areas like N Wales – low population but high rainfall totals (200mm p.a) www.geobytesgcse.wordpress.com St Ivo School Geography Department - GCSE REVISION Point source pollution – contamination resulting from emissions from a particular location. Define point source pollution and give an example of this in an LIC. www.geobytesgcse.wordpress.com Fold along
