Pressure is given as : height X Density X accln due to gravity So pressure is directly proportional to height or depth. So as the depth of water increases , pressure exerted increases. So dams are made broader at the bottom to sustain the pressure

dams and tall buildings are made broader at the bottom because if the bottom area will be less, the pressure exerted will be more due to which the building might fall or break
