Impacts of climate change on water resources and water environment in the Three Gorges Reservoir
Climate change is one of the major global issues commonly concerned by international communities. Taking the Three Gorges Reservoir which is the largest water conservancy project in China as the object, this study attempts to clarify the current conditions of water resources and water environment especially the spatial distribution characteristics of water resources amount and main non-point so...
متن کاملPopulation , Natural Resources and Environment
Population-environment studies have implicitly permeated demography but only until the mid-20 century has the debate been rekindled and research expanded. This article reviews the origins and history of the population-environment debate and attempts to provide insight into the most recent approaches and methodology. Beginning with the most traditional relationships established between demograph...
متن کاملHydrology and Water Resources 4
CONTENTS • There are apparent trends in streamflow volume—both increases and decreases—in many regions. These trends cannot all be definitively attributed to changes in regional temperature or precipitation. However, widespread accelerated glacier retreat and shifts in streamflow timing in many areas from spring to winter are more likely to be associated with climate change. • The effect of cli...
متن کاملSustainable soil and water resources: modelling soil erosion and its impact on the environment
With the projected increase in world population to 9 billion by 2050, along with per capita income growth, the demand for land and water resources is going to increase significantly. Conversion of land to intensive agriculture has led to dramatic decreases in plant, animal and insect biodiversity, with approximately 40% of the world’s land surface now covered by croplands and pastures. Intensiv...
متن کاملWater Resources Bulletin
During waning flood flows in gravel-bed streams, finegrained bedload sediment (sand and fine gravel) is commonly winnowed from zones of high shear stress, such as riffles, and deposited in pools, where it mantles an underlying coarse layer. As sediment load increases, more fine sediment becomes available to fill pools. The volume of fine sediment in pools can be measured by probing with a metal...
