The place in Picture B is more prone to flooding. This is because the ground is made of concrete tiles, this means that the ground is less permeable, which means that less water is be able to infiltrate into the ground. This causes more surface runoff and thus there is an overflow of large amounts of water on land that is normally dry, resulting in floods.

I think it's picture because the picture shows brick tiles which has a low permeability thus would not allow water to infiltrate this causing flooding as the water has no other place to go and would remain on the normally dry surface of the road

Picture b is more prone to flooding because there is no vegetation in picture b but just concrete. Thus, there will be more surface runoff than infiltration in picture b.

1. Picture B is more prone to flooding
2. Reason: permeable of surface cover
3. Explain: it’s a concrete surface as it’s made of tiles which means Low permeability thus water can’t be filtrate easily

Picture B has lower permeability than picture A. picture B has a concrete surface while picture A has dense vegetation. Water cannot infiltrate the ground easily in picture b, there is a high surface runoff resulting of overflowing of large amounts of water onto land that is normally dry. Hence picture b is more prone to flooding than picture a

Picture B
cos its concrete
Its has a low permeability, which leads to more surface runoff , causing higher chances of flood

picture B is more prone to flooding because in urban areas have concrete floors which are less permeable for infilratrion causing more surface run off causing flooding also in picture A it is a rainforest which may harbour some water ways that could lead thr water to rivers or ponds or lakes-ur onii chan

Picture B is more prone to flooding as the area is mostly made out of cement, unlike picture A, which is mostly vegetated surfaces. As the cemented surfaces are less permeable than the vegetated surfaces, the amount of surface runoff will be higher, causing less water to infltrate into the ground, resulting too much water build up, causing and overflow of water onto land that is normally dry, resulting in a flood

B, it has Low impermeability as it is a concrete surface

Picture B is more prone to flooding because of the low permeability of surface cover which means that water cannot infiltrate into the ground easily. It has concrete surfaces which is impermeable and water is unable to infiltrate into ground. Thus, there is an increase in surface runoff compared to the vegetated surface cover in picture A which results in the overflows of large amount of water onto land that is normally dry and causes flooding

Picture B
Reason: picture B shows concrete surface covers while picture A shows vegetated surface covers
Explain: permeablility is the ease at which water infiltrate into a surface cover. Vegetated surface cover does not allow water to infiltrate and hence made it impermeable
Concrete surface covers allow water to infiltrate in and hence made it permeable

The city is surrounded by concrete which means that when it rains, the water will not be able to infiltrate into the ground. Thus, Low permeability of surface cover make these cities prone to flooding because of the high surface runoff due to the concrete surfaces. This in turn leads to overflows of large amounts of water of water onto land that is normally dry. Another way cities make themselves prone to flood is because as it slowly expands, the land that used to be natural vegetation will be removed and replaced by concrete and water will not be able to seep into the ground.

Picture b is more prone to flooding because the floor of the streets are made form a material that does not allow water to infiltrate. Thus making the ground impermeable which leads to high surface runoff which makes picture b more prone to flood

Picture B is prone to flooding because its surface is concrete which has low permeability that allows more surface runoff and lesser infiltration which causes flood in normally dry places.

Picture B is more prone flooding as it is a concrete surface and therefore is impermeable, resulting in a overflow of water in the areas that are normally dry.

Picture B is more prone to flooding due to the small channel capacity and is made out of concrete which is impermeable hence water is unable to infiltrate into the ground. as a result, this leads to an increased risk of water being collected and water level collected to rise, resulting in flooding. thus, flooding is more prone to occur in Picture B as flooding refers to large amounts of water overflowing over land that is normally dry.

Picture B is more prone to flooding due to it having a concrete surface instead of a vegetated surface Thus , Less water will infiltrate the ground is more prone to Flooding By : DS Dhanvin and Asyura

Picture B is more prone to flooding.Due to lower permeability of surface cover picture B is more prone to flooding.Picture B has concrete surface which has low permeability.There is high surface runoff due to the presence of impermeable surface.This in turn results in the overflows of large amounts of water onto land that is normally dry.
