North Saskatchewan River flood of 1915

North Saskatchewan River flood of 1915 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand North Saskatchewan River flood of 1915 rather than just read about it. In short: The North Saskatchewan River flood of 1915 was one of the largest floods in the history of Edmonton. On 28 June, the Edmonton Bulletin reported the river had risen "10 feet [3.0 m] in as many hours." A frantic telegram from Rocky Mountain House alerted local authorities to the flood's arrival.

Reference excerpt

The North Saskatchewan River flood of 1915 was one of the largest floods in the history of Edmonton. On 28 June, the Edmonton Bulletin reported the river had risen "10 feet [3.0 m] in as many hours." A frantic telegram from Rocky Mountain House alerted local authorities to the flood's arrival. The water rose to the deck level of the Low Level Bridge and debris was gathered along the bridge. The debris included a house swept away by the current. The Canadian Northern Railway parked a train on the bridge to hold the bridge down and try to prevent it from being swept away. At its highest point the river was estimated to have risen to over 13 metres (42 ft) above the low water level, even higher than the worse previously known flood in Edmonton, the 1899 flood. Thousands of Edmonton residents watched the flood destroy lumber mills along the city's river valley. At the time the river valley was a hub of the city's industrial activity, including lumber and boatbuilding businesses, brick yards, coal and gold mining, and breweries, many of which were severely damaged, suffering enormous losses. No lives were lost, and no serious injuries are attributed to the flooding, but 2000 Edmontonians lost their homes, with 700 houses severely damaged and 50 swept away completely. Most of the people who lost their homes were members of Edmonton’s working class and could hardly afford replacing their homes and belongings. The Edmonton Bulletin estimated damage to the businesses and homes to total three-quarters of a million dollars, all without flood insurance. Like all rivers, the North Saskatchewan River is subject to periodic flooding, caused by rapid snowmelt in its headwaters in the mountains or heavy rain in its river basin. With the establishment of permanent communities along the river's course, administrative/government records exist recording floods in the North Saskatchewan occasionally over the past century. The river is known to have flooded in 1830 (due to an ice dam of the flow) but the 1899 flooding of the river was the first summer-time flood of the river in known human experience or local folklore. The 1915 flood peaked at about four metres higher than the 1899 flood. The Bighorn Dam, constructed in the early 1970s near Nordegg, Alberta, and the Brazeau Reservoir, constructed in the mid-1960s, have not eliminated the possibility of flooding on the North Saskatchewan River.

Worked examples

Example 1 — a first encounter with North Saskatchewan River flood of 1915

Start with the simplest possible case. Write down what North Saskatchewan River flood of 1915 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to North Saskatchewan River flood of 1915 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about North Saskatchewan River flood of 1915 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of North Saskatchewan River flood of 1915

In research: North Saskatchewan River flood of 1915 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses North Saskatchewan River flood of 1915 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: North Saskatchewan River flood of 1915 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1910s floods, 1910s in Edmonton, 1915 disasters in Canada, so understanding it makes those chapters shorter.
In everyday life: Look for North Saskatchewan River flood of 1915 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
