Accounting for Hydrologic and Land-Atmospheric Functions of Man-Made Reservoirs across Canadian Regions

人工水库是加拿大和世界各地水资源管理的关键，用于多种目的，从水力发电到供水，防洪和娱乐。尽管有重大的社会经济效益，大规模的环境变化与水库运行。最重要的是，水库的蓄水具有显著的调节作用，在时间和空间上严重扰乱了径流和地表水的储存。此外，水库将自然土地覆盖物变为开放水域，因此扰乱了土地与大气之间的水和能量通量。这可能会进一步与当地和区域气候相互作用，并导致一种新形式的“人为气候变化”，而不仅仅是温室气体的排放。

Manmade reservoirs are key to water resource management in Canada and throughout the world, and are used for multiple purposes, ranging from hydropower production to water supply, flood protection and recreation. Despite major socio-economic benefits, massive environmental changes are associated with reservoir operation. Most importantly, significant regulative effects are associated with reservoirs’ impoundment, which can severely perturb the streamflow regime and surface water storage in time and space. In addition, reservoirs alter the natural land cover to open water, and therefore, perturb the water and energy fluxes between the land and the atmosphere. This may further interact with local and regional climate, and lead to a new form of “anthropogenic climate change”, beyond the emission of Greenhouse Gases.
