- River Regimes in different climate
- The Yukon, Alaska
- polar in winter, warmer in summer
- precipitation is frozen in winter, flow is low
- summer - snowmelt causes flow to be higher
- polar in winter, warmer in summer
- The Amazon
- tropical climate - consistent temperature and precipitation
- high biodiversity means high evapotranspiration
- seasonality - consistent river flow - El Nino and La Nina may produce changes in rainfall which affect river discharge
- deforestation- affects interception, infiltration and surface run off
- dams can cause more discharge above the demand reduce flow below it
- The Murray-Darling, Australia
- sub-tropical
- much of it is in a rain shadow - surrounded by mountains which collect rain and can cause long periods of drought
- clear wet and dry seasons which changes flow of the river
- El Nino brings less rain but La Nina brings wetter and colder conditions
- water is used in the cities and for irrigation - natural flow altered for human access which had led to loss of habitat
- The Yukon, Alaska
