1. How would you respond to the following 'statement' in a
scientific sound way? "There is sufficient water available globally
- this will not
change as a result of climate change. The global water supply is
therefore not a problem!
a) In total there will be and always has been enough water per
person theoretically available. The issue is that not all regions
share the same access to water, especially clean drinking
water. There is also the issue that many regions experience
dry periods within which the water
demand can also not be met, think rainy season
and dry season in Asia. Additionally, there may not be enough
quality drinking water in regions due to organic or chemical
pollution.
,1. Why will the 'water shortage' 'worsen' in some regions of the
world? Which are they?
a) Due to climate change rainfall patterns will change as the
global water cycle adapts to higher temperatures (more water
storage in warmer air)
and rising ocean levels. This may lead to extended droughts or short and
intense rainfall patterns
where large shares of annual rainfall falls within hours or days.
Another issue is that higher
temperatures can lead to snow droughts in the mountains that recharge
river flows and
groundwaters normally during the year. African countries and
Southeast Asia will experience periods of extremely low
available water.
,What were the controlling factors for the July 2021 Ahr flood?
Floodplains were disconnected, incomplete
integration of historical information regarding
flooding potential, hubris to deal with precipitation mainly with
canalization, steep valley and flat soils
1. Which climatic conditions could have
exacerbated the 2013 Danube flood? (also 2004)
Strong rainfall lead to the flooding. The floods were exacerbated
due to heavy rainfall days before, leading to a limited soil water
infiltration potential increasing direct surface runoff in the
catchment. A good thing was that cold
temperatures in parts of the catchment made the precipitation fall as
slow, which slowed that waters entrance into the river.
, 1. Name 3 measures to protect against
pluvial/fluvial flooding and explainhow they work.
a. Pluvial
i. Increase the soil water infiltration capacity by reducing the
amount of sealed area in a region,
allowing for deep percolation of water or increase drainage via culverts.
ii. Build houses on stilts, so that the essential parts of the house
can sustain a certain height of the water column before being
affected.
iii. Built retention basins for drainage systems where
large amounts of water can be led to, limiting the surface
water height
b. Fluvial
i. Reconnecting floodplains means slowing down the water, as
well retaining parts of it
ii. Allowing for river dynamics, such as widening
also slows down the water and allows for a greater transport capacity in
case of surplus water
