Urbanization increases the risk of flooding primarily by replacing natural landscapes with impervious surfaces like roads and buildings, which prevent water from being absorbed into the ground. This leads to increased surface runoff during heavy rainfall, overwhelming drainage systems and waterways. Additionally, urban areas often have altered topographies and reduced vegetation, which further exacerbate flooding risks. Climate change can intensify these effects, resulting in more frequent and severe flooding events.
Humans can increase the risk of flooding through activities such as urbanization, deforestation, and poor land management practices that can lead to increased runoff and reduced water absorption capacity of the land. Climate change can also exacerbate flooding events by altering precipitation patterns and increasing the severity of storms.

Built-up areas increase the risk of flooding by increasing the amount of impervious surfaces like pavement and buildings, which prevent water from soaking into the ground. This leads to more runoff during heavy rain, overwhelming drainage systems and causing localized flooding. Additionally, urbanization can disrupt natural drainage patterns, increasing the likelihood of flash floods.
Urbanization can increase surface runoff by replacing natural surfaces with impermeable ones like pavement and buildings, which prevents water from infiltrating the ground. This can lead to higher volumes of water flowing over land and into waterways, increasing the risk of flooding and water pollution. Urbanization also disrupts natural drainage patterns, further exacerbating surface runoff issues.
Living below sea-level, I mean just look at New Orleans... High rainfall and like you said living below sea-level like Bangladesh they are 1m above sea-level. deforestation and urbanisation

Humans can indirectly cause floods through activities such as deforestation, urbanization, and land development that disrupt natural drainage patterns and increase the risk of flooding. Climate change can also exacerbate flood events due to extreme weather patterns.
Urbanization has been blamed for the increase of childhood asthma issues.

the role it plays is that they keep all the flooding away
Saturated soil cannot absorb additional water, leading to surface runoff during heavy rainfall. This runoff can quickly accumulate and overwhelm drainage systems, increasing the risk of flooding in the area.
