Assessing the degree of ecological change and baselines for reservoirs: challenges and implications for management [PDF]

open access: yes, 2019
Tropical reservoirs are sensitive to eutrophication but long-term impacts of impoundment on their productivity and biota are poorly understood. Here, we employ a palaeolimnological approach to assess whether ecological baselines can be defined for ...

Improving Flood Simulation Performance of Distributed Hydrological Model in the Plain–Hilly Transition Zone via DEM Stream Burning and PSO

open access: yesRemote Sensing
Accurate flood simulation and forecasting in plain–hilly transition zones remain challenging due to limitations of medium- and low-resolution digital elevation models (DEMs), which often produce discontinuous drainage networks and misaligned confluence ...

Simulation of Karst Floods with a Hydrological Model Improved by Meteorological Model Coupling

open access: yes, 2022
Karst basins are prone to rapid flooding because of their geomorphic complexity and exposed karst landforms with low infiltration rates. Accordingly, simulating and forecasting floods in karst regions can provide important technical support for local ...
