removal of vegetation

there are no roots to collect, filter, or absorb the rain water

paved roads = more runoff

paved roads, parking lots, and sidewalks increase runoff and cities must build, maintain, and finance stormwater systems

wetlands destruction

the wetlands act like sponges and stores water and when drained or built on, rain can no longer be absorbed

creating concrete rivers

developers create concrete rivers to channel water away from the development and this prevents absorption and harms river life

physical causes

flooding happens when vegetation is low, slopes are steep, or rainfall is heavy and long, because water runs off quickly and the ground can’t absorb it fast enough.

human causes

More pavement, broken city pipes, and building in flood-prone areas all increase flooding because they stop water from soaking in or put people in risky places.

flooding solution: bioswales

A bioswale is a shallow, plant-filled ditch that slows down rainwater, filters out pollution, and helps water soak into the ground instead of causing flooding.

Protect Wetlands

Wetlands are very important - to plants and animals but also to people as they absord huge quantities of Water

preventing and managing flooding

Flood agencies warn people, and floodplains are risky places to build because they flood easily.

legisation and education

laws, forecasting, and education help reduce flood damage and keep people safe.

Climate

is average

weather

is now

Making a climate graph (know the components)

red line teperature (oC) and blue bars for precipitation (mm)

Interpreting a climate graph: wet

look at the bars (precipitation) wet = tall bars = lots of rain

Interpreting a climate graph: dry

look at the bars (precipitation) dry → short bars, not much rain

Interpreting a climate graph: warm

look at the line (temperature) warm = stays high (around 15°C or more)

Interpreting a climate graph: cold

look at the line (temperature) Cold = low temps, may go below 0°C

Interpreting a climate graph: Continental Climate

Big temperature difference (hot summers, cold winters) usually less precipitation temp range is large (25°C or more)

Interpreting a climate graph: Maritime Climate

Small temperature difference more precipitation temp range is small (less than 25°C)
