China's longest river - Chang Jiang.

Catchment - 1/5 of China.

Hydroelectric power - vital for china;s economimc development.

40% of China's output.

Human causes of flooding - soil erosion in upper catchment, land lost to grow more food because of population pressure, rapid urban growth meaning less infiltration.

Physical causes of flooding - huge catchment area, localised rain, timing and amount of rain varies in each sub basin.

Benefits of dam:

The hydropower provides 10% of China's current needs.

It creates jobs causing economic growth.
