Faint o bobl sy'n byw ar yr arfordir yn y DU?
3
miliwn
View source
Pam mae rhai cymunedau'n fwy agored i niwed na eraill?
Oherwydd eu
lleoliad
a'r peryglon fel ymchwyddiadau storm ac
erydu arfordirol
View source

Ymchwyddiadau
storm
ac erydu arfordirol
View source
Pam mae cymunedau ar hyd M么r y Gogledd yn arbennig o agored i niwed?
Oherwydd
digwyddiadau
sy'n gysylltiedig 芒'r tywydd fel ymchwydd
stormydd
View source
Beth sy'n achosi ymchwydd stormydd?
Gwyntoedd cryfion
a gwasgedd isel
View source
Faint gall lefelau'r m么r godi oherwydd ymchwydd stormydd?
Hyd at 5 metr
View source
Beth yw canlyniad ymchwydd storm 5.8 metr ar 5 Rhagfyr 2013?

Ymchwydd
stormydd
, llanw uchel a
gwyntoedd
cryfion
View source
Sut gall daeareg arfordirol gynyddu perygl i gymunedau?
Mae daeareg wan yn cynyddu cyfradd yr erydiad
View source
Beth yw'r effaith o glog-glai ar gyfradd erydiad?
Mae cyfradd yr erydiad yn uwch na phe bai daeareg y clogwyn yn graig galed
View source
Pa gymunedau sy'n arbennig o agored i lefelau'r m么r yn codi?
Cymunedau ar dir isel, llai na 10 metr uwchben lefel y m么r
View source

Maen nhw'n fwyfwy agored i lifogydd ac erydu arfordirol
View source
Beth yw'r prif beryglon i gymunedau arfordirol yn y DU?
Ymchwyddiadau
storm
Erydu arfordirol
Gwyntoedd
cryfion
Llanw uchel
View source
Sut mae daeareg yn dylanwadu ar agored i niwed cymunedau arfordirol?
Daeareg wan =
cyfradd
erydiad
uwch
Daeareg galed = cyfradd erydiad
is
Daeareg clogwyn =
effaith
ar
lefelau'r m么r
View source
Beth yw'r cysylltiad rhwng lefel y m么r a chymunedau arfordirol?
Cymunedau ar dir isel = mwy agored i
lifogydd
M么r y Canoldir
yn codi = perygl i gymunedau
Delta'r N卯l
= lleoliad agored i niwed

View source
What are the four human factors that affect community vulnerability to flooding and erosion?
Wealth
,
education
, age, and access to

How does wealth affect community vulnerability to flooding and coastal erosion?
Poor
communities are less likely to afford weather-resistant housing.

High-income
countries can invest in flood risk reduction measures.

Trains professionals for
emergency
action plans.
View source

experience
and depend on others for guidance
