What causes Floods?
Heavy Rainfall: Causes increase in sea level rise etc.
Over–saturated soil (when the ground can’t hold in any more water and could turn into mud etc): Infiltration can’t take place due to the soil’s impermeability resulting in so then surface run off will be increased.
Bangladesh suffered one of its worse floods ever. Despite being flooded being common in this country, the floods of 1998 were particularly severe resulting in over 1000 deaths and 30 million people being made homeless.
