Impacts of vegetation and human activities on temporal variation of the parameters in a monthly water balance model

Shui kexue jinzhan, 2018
The non-stationary nature of watersheds due to changing environments has invalidated the assumption that hydrological model parameters reflecting the physical characteristics of watersheds were time-invariant. To improve the performance of a hydrological

Exploration on hydrological model calibration by considering the hydro-meteorological variability

Hydrology Research, 2020
The hydrological response is changeable for catchments with hydro-meteorological variations, which is neglected by the traditional calibration approach through using time-invariant parameters.

Urbanization and hydrological conditions drive the spatial and temporal variability of microplastic pollution in the Garonne River.

Science of the Total Environment, 2021
Microplastic (MP) pollution represents a novel environmental pressure acting on freshwater ecosystems. Improving our understanding of the dynamics of MP pollution in freshwater ecosystems is therefore a prerequisite for managing and limiting this ...

Longitudinal Dynamics of Hydrological Connectivity in the Yellow River Delta, China

Frontiers in Marine Science, 2022
River deltas are formed by the interaction of connecting water and sediment, and they are among the most economically and ecologically valuable ecosystems on Earth. Because of their special locations, together with direct and indirect human interference,
