- factors affecting discharge
- Impermeable Rocks
- e.g granite and soil (e.g clay) will not allow water to pass through
- large amounts of surface run off and greater flood risks
- e.g granite and soil (e.g clay) will not allow water to pass through
- permeable rocks
- high infiltration capacity and will reduce overland flow
- steep gradient drainage basin
- greater overland flow
- heavy rain
- if the soul has already been saturated by heavy rain there is a reduced infiltration capacity
- slow light rain
- impermeable man made surfaces
- such as concrete or tarmac will result in higher discharge
- due to higher amounts of surface run off
- such as concrete or tarmac will result in higher discharge
- vegetated areas
- help to reduce flood risk through infiltration
- dry soil
- able to absorb more water therefore slower increase of discharge
- temperature
- hot-more evaporation therefore more discharge
- cold- little transpiration therefore increased discharge
- hot-more evaporation therefore more discharge
- Impermeable Rocks
