Transcript of Western Cordillera

Western Cordillera Location West coast of North America
Yukon to British Columbia and western Alberta Age Mesozoic and early Cenozoic periods
30-100 million years ago Physical features of the landscape Jagged mountains
"U" shaped valleys
3 major mountain ranges:
Cascades, coastal and rocky
Hills, plains and ridges Climate Little percipitation
2500 mm of percipitaion in the cascades and coastal ranges and less than 250mm in the plateau country
It's like the Maritime climate
Wet during fall and winter Vegetation Differs tremendously
Douglas fir, Red Cedar, and Hemlock grow in the moist areas
In the South evergreens do not grow due to the lack of percipitation Population How it was created The collision of the North American and Juan de Fuca plates Popular tourist attractions Rocky mountains
Vancouver art gallery, which contains two must-see exhibitions
Vancouver Aquarium, which contains over 70,000 captivating creatures
Many fine dinning areas and architecture in Vancouver such as their One wall center Height 150 m
Floors 48
Year 2001 Blue water cafe Has the largest selection of oysters Approximately 4,533,929 people By Yousaf Hussain Thank you for watching my presentation and I hope all of you were able to learn something new :) Definition "A long and wide chain of mountains, especially the main mountain range of a large landmass. Cordilleras can include the valleys, basins, rivers, lakes, plains, and plateaus between parallel chains of a single mountain system, or they can consist solely of a string of connected mountain peaks." Definition taken from dictionary.refrence.com

Climate change is projected to have significant impacts on the future water resources of Canada. A particularly critical region involves the leeward slopes of the western cordillera where changes to the amount of snow and ice resources could have adverse effects not only for the cordillera region itself, but also for the downstream locations that rely heavily upon these resources. For example, the Peace-Athabasca Delta (PAD) relies heavily upon upstream water resources for the beneficial flooding of riparian ecosystems. In certain years, however, large snow pack conditions can result in flood hazards to several communities. In the context of this workshop, activities in the South Saskatchewan River basin including for example, irrigation, agriculture, municipal water supply and quality, and recreation also rely on the amount and timing of water supplies from headwaters of the cordillera. To determine impact and adaptation strategies for these downstream regions, reliable estimates of future changes and variability in the cordillera™s water supplies are required. At this time, however, there is limited knowledge regarding the impacts of future changes to temperature and precipitation on the magnitude and timing of water resources from the leeward slope region of the western cordillera. This study addresses these knowledge gaps.The simulated current (1961-90) monthly temperature and precipitation output from seven different GCMs (recommended by the IPCC for scenario impact studies) will be compared to various observed climate data sets (gridded data, observed station data, previously developed snow and ice data set) over the leeward slopes of the western cordillera. Based on the assessment, it will be determined which GCM or ensemble of GCMs best represents the current climate over the region. A series of predicted (e.g. 2x CO2) changes from the selected GCM(s) will then be applied to observed climate over the study area to produce multiple scenarios of future temperature and precipitation values at the daily scale. Note that most previous impact scenarios have relied only on monthly data but this is not a suitable time step for assessing intra-seasonal changes in snow runoff regimes. A methodology to apply daily GCM output to observed climate has already been developed at NWRI. These future daily temperature and precipitation scenarios will subsequently be used in a snow pack model (e.g. SNOW THERM) to determine a range of possible future snow pack conditions over the study area (i.e. amount, density structure, timing of spring melt). These factors are critical for spring runoff and thus, hydrological conditions downstream. At this point, a thorough review ofusable alpine region hydrologic runoff models (that incorporate daily temperature and precipitation data) will be conducted and the best model or models chosen. Key nodes representing different hydro-climatic regimes will then be selected (e.g. headwaters of the Liard, Peace, and South Saskatchewan rivers) and the chosen hydrologic model(s) used to construct scenarios of future runoff regimes over the various regions. A review of climate change impact case studies over the study area, as well as, similar regions around the world will be carried out and with the results from this investigation, the most likely scenarios of future runoff characteristics (amount, timing of spring freshet) will be determined. As this work continues, the results will be discussed with various stakeholders to determine implications for future economic and environmental activities including hydro-electric power generation, agricultural demand, extreme events, and trans-boundary (provincial and international) water agreements. In addition to reports on each sub-objective, a final summary report describing all findings and recommendations will be produced. This study will directly address the vulnerability of the primary source of flow from the western cordillera to climate change. Snow melt from this alpine area is the dominant source of water feeding the hydroelectric and agricultural systems operating in the prairieportions of Alberta and Saskatchewan. Consultations with stakeholders regarding the nature of the projected hydrologic changes assessments will also be made: a) to identify the sensitivity of the current organizational (including trans-boundary water agreements) and physical structures to such change, b) to quantify critical thresholds in seasonal availability of water, and c) to determine potential adaptation strategies or barriers in the water-use systems.

4.Notes from Class
5.World geography book
6.Regions of Canada book
7.Google search: What is the western cordillera first search link/website Definition of words Cascades: Anything that looks like a waterfall.

Coastal: Located near a coast

Rocky: Full of rocks Types of Rocks: The types are Igneous, sedimentary, Metamorphic Also, they are said to came there 65 million years ago. Human Interaction Hiking
Climbing The size and frequency of avalanches in our western mountains parks is expected to increase. This would enhance the habitat of some species such as hoary marmot. However, it would also increase safety hazards for back country travelers.

Biomes in this region will be the most susceptible to elevation shifts. Ba niff National park alone contains 41 plant species that reach their range limits in the park and that will particularly sensitive climate change.

Warmer spring and fall temperatures will extend the melting season of glaciers by at least a month in the Southern Rocky mountains. Glaciers that are less than 100m thick could disappear in the next 20 years. God had finished the Earth but there was nothing on it
God then created 2 kids called dumber and other because he was so tired
I know what your thinking but dumber is smart and other is dumb
The brothers found the area in ruins with nothing
The Brothers had amazing powers created animals, human, nature etc.
But then dumber started to fight with other and kick him out because dumber did most of the work to create this world
other went and lived inside what we know as the pacific plate
Dumber and other had wars for years but when dumber was dying he hid himself inside the north american plate
The plates collied for years after years that created the mountains to protect humans from the battle
when the mountains formed the humans called the region bwalka or as we call it the western cordillera
even now the brothers are fighting without caring of the humans
But when the world ends or when one of them dies then they will see what they have done from this war.
