Flood management describes methods used to reduce or prevent the detrimental effects of flood waters. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Flood management methods can be either of the structural type (i.e. flood control) and of the non ...
These techniques may be used in the identification of flood dynamics, [22] [23] storm characterization, [24] [25] and groundwater flow in karst systems. [26] Regression analysis is used in hydrology to determine whether a relationship may exist between independent and dependent variables.
[8] [81] During a presentation of the report to the Empire Club of Canada, McBean associated flooding of Toronto's Union Station on June 1, 2012, with "unthinkable" severe weather and other historic floods in Canada (see presentation 3:14), while it was later revealed the flooding was caused by construction contractors actions and the removal ...
Atmospheric rivers of the sort causing massive floods and mudslides in Canada's British Columbia are akin to a river in the sky, weather systems that carry up to 15 times the volume of the ...
Due to an increase in heavy rainfall events, floods are likely to become more severe when they do occur. [59]: 1155 The interactions between rainfall and flooding are complex. There are some regions in which flooding is expected to become rarer. This depends on several factors. These include changes in rain and snowmelt, but also soil moisture.
The 2019 spring floods in Ontario, Quebec and New Brunswick were exceptional floods in eastern Ontario, southern Quebec and from the St.John River region to New Brunswick, Canada. In fact, flooding along the Ottawa River has been recognized as the most important weather event of the year 2019 in Canada, and the one along the Saint John River as ...
gives Canada equal credit to U.S. projects existing in 1961 (better than first added), ignores the flood control benefits provided by Libby and other post-1961 U.S. projects, and; also ignores the flood control benefits provided by the Canadian power storage operation that normally drafts far more than the 8.45 Maf flood control obligation.
It is a method of controlled and intermittent irrigation. A periodic drying and re-flooding irrigation scheduling approach is followed in which the fields are allowed to dry for few days before re-irrigation, without stressing the plants. This method reduces water demand for irrigation and greenhouse gas emissions without reducing crop yields.
