Many criticize Bible because it talks about Global floods at the time of Noah. They think it is a big mistake. Muslims believe that Noah's floods were local. They think Quran corrected that stories which exists in the Bible. However from what I understand, Noah's flood are global in Quran as it seems. It can be seen from the following verse
So We inspired him (with this message): "Construct the Ark within Our sight and under Our guidance: then when comes Our Command, and the fountains of the earth gush forth, take thou on board pairs of every species, male and female, and thy family- except those of them against whom the Word has already gone forth: And address Me not in favour of the wrong-doers; for they shall be drowned (in the Flood).
Then the word went forth: "O earth! swallow up thy water, and O sky! Withhold (thy rain)!" and the water abated, and the matter was ended. The Ark rested on Mount Judi, and the word went forth: "Away with those who do wrong!"
Noah builds the ark and collected all kinds of specie in pair, then the ark lands on a mount. Wouldnt this mean the floods were global. This link says says
Apart from those who boarded Prophet Nuh's (as) Ark, the entire tribe was drowned. The dead included the Prophet's son who thought he could escape by seeking shelter on a mountain.
So why was it not global flood. If you consider that Earth was considered flat at that time, this makes perfect sense. My other argument is one needs only about 100 ft of flood water (esp in those times) to destory a particular tribe. We are talking about Mountains here.
