floods

types of floods

riverine flooding - flooding that develop when prolonged + widespread rainfall cause natrual water wau like river,creek rise beyond their normal capacity + spill over banks

flash flooding - severe storm w high bolumes of rainfall over short period of time

storm surge = abnormal rise of sea level + tide level due to storm - water pushed to shore

impact flood

damage service + infrustucture

• replacement + repair = very expensive + take long time

loss acess to public service

• school, hospital,day care + agecare = loss of acess / damaged

contamination of floodwater - threat to health of ppl + animal

• increase risk of diseases

• damage farm

• crops = wasted/ruined - harvest delays +economy impact+ foodsortages+ inflation

• crops + rescorces die underwater - lose food supply + money

soft engineeering

using natural processed to manage flooding more sustainable

afforestaion - planting more trees to redice run off + increase water being drawn into plants

river restoration - restoring river to natrual course(less straight) which slow the flow of ruver

hard engineering

man made physical structcure built to control flow of water + reduce flooding

dams - reduce risk of flooding

leevees - man made embankments along edge of river - increase capacity of channel to prevent over flow of water

impacts of floods

damage to services + infrustructure

rroads,railways, electricity - inaccessible + washed away

loss acess to public services

schools , hospitals ,= loss acess + damaged

contamination of floodwater - threat health of ppl + animal

increase risk of disease

agriculture impacts crops = wash away - harvest delay + food shortage + local ecnomoy impact

short term impacts

damage to services + infrustrucutre w waste water + electricity + sewerage damaed

nusinesses, homes washed way

long term impacts
