In Spring 2011, Manitoba experienced the worst flood it had gotten in 300 years. The flood overflowed dry land with extreme amounts of water. This flood lasted more than 2 months! Giving Manitoba its worst. The premier had to go as far as contacting the Prime Minister to get help from the troops.
It all started winter of 2010. Winnipeg, being a city in Canada, got lots of snow in the winter anyways but this time, the state (Manitoba) received above normal precipitation. This means, the more snow in the winter, the more to melt in the spring. On top of this the temperatures did not raise a single degree above the freezing mark between November 17th and February 3rd. Normally, they see around 7-8 days. The cold lead to a froze ground which could not absorb the snow and rain. Therefore, resulting in a flood in the spring (April- June). When the temperatures started to cool down, the rivers started to swell, breaking the layer of ice at the top of the rivers. The caused ice jams, large chunks of ice floated downstream causing damage to what ever what at the destination. This is what happened to Assiniboine River. …show more content…
But you may be wondering, how did scientists measure this flood? Well the tool used during floods are called rain gauges, in specific, stilling wells as these are what floods are measured with. These are the most common way of measuring precipitation. Rain gauges work quite simply; they are dug into the soil with measurements labelled on them. We read how many millimetres or inches are collected in the rain gauge from a passing storm or flood. This determines the level of water
