Anthropization and Climate Change: Impact on the Discharges of Forest Watersheds in Central Africa
climate change urbanization impervious area Cameroon runoff
2023/12/15
Climate change and anthropization are major drivers of river flows variability. However, understanding their simultaneous impact on discharges is limited. As a contribution to address this limitation,...
The Millennium Drought (southeastern Australia) provided a natural experiment to challenge the assumption that watershed streamflow always recovers from drought.
Delineation of eco watersheds by integration of Remote Sensing and GIS techniques for management of water and land resources
Eco watersheds PC analysis Water Resources Hierarchical Clustering
2016/5/20
Present study describes the concept of eco-watersheds. Eco watershed is described as the homogenous watershed which have similar characteristics for natural resources development and management practi...
