Search for my resource (mind map) 'Impacts of human activities on flooding.' That should cover everything (river flooding that is, coastal flooding probably has different reasons).

Deforestation means there is less interception and evapotranspiration so more run off
Urbanisation leads to impermeable surafaces and drains so more run off
Channel straightening means river flows faster so increases flood risk downstream

  • If deforestation occurs flooding occurs as less rain is intercepted by the trees
  • If mangroves are destroyed in order to develop coastal areas flooding is more likely to occur
