Comparison of Precipitation and Streamflow Correcting for Ensemble Streamflow Forecasts [PDF]

Water, 2018
Meteorological centers constantly make efforts to provide more skillful seasonal climate forecast, which has the potential to improve streamflow forecasts. A common approach is to bias-correct the general circulation model (GCM) forecasts prior to generating the streamflow forecasts.

Quantifying the streamflow change and influencing factors with a spatio-temporal coupling analysis framework

Journal of Water and Climate Change, 2023
Streamflow change and its influencing factors are synchronous and correlated in temporal and spatial scales. The aim of this study is to develop a spatio-temporal coupling analysis framework for quantifying streamflow change and its influencing factors ...

Investigation of cross-entropy-based streamflow forecasting through an efficient interpretable automated search process

Applied Water Science, 2022
Streamflow forecasting has always been important in water resources management, particularly the peak flow, which often determines the seriousness of the impending flood. However, the highly imbalanced flow distribution often hinders the machine learning

Hydrological drought forecasting and monitoring system development using artificial neural network (ANN) in Ethiopia

Heliyon, 2023
The objective of this study is to investigate and perform long–term forecasting of both streamflow and hydrological drought over Ethiopia. Observed streamflow and precipitation data are collected from 17 streamflow stations and 34 rainfall gauge stations

Improving the Distributed Hydrological Model Performance in Upper Huai River Basin: Using Streamflow Observations to Update the Basin States via the Ensemble Kalman Filter

Advances in Meteorology, 2016
This study investigates the capability of improving the distributed hydrological model performance by assimilating the streamflow observations. Incorrectly estimated model states will lead to discrepancies between the observed and estimated streamflow ...

Temporal dynamics of streamflow: application of complex networks

Geoscience Letters, 2018
This study employs the concepts of complex networks to study the temporal dynamics of streamflow, with emphasis on annual scale (i.e., year-to-year connections).

Elasticity curves describe streamflow sensitivity to precipitation across the entire flow distribution [PDF]

Hydrology and Earth System Sciences
Streamflow elasticity is the ratio of the expected percentage change in streamflow to a 1 % change in precipitation – a simple approximation of how responsive a river is to precipitation.

Study on streamflow similarity regionalization based on nonlinear correlation and complex network

Shui kexue jinzhan, 2022
Streamflow similarity regionalization is significant for interpolating and transferring streamflow data and regional flood frequency analysis. To accurately identify the similarities and differences of streamflow characteristics of different hydrological

GRACE Satellites Enable Long-Lead Forecasts of Mountain Contributions to Streamflow in the Low-Flow Season

Remote Sensing, 2021
Terrestrial water storage (TWS) in high mountain areas contributes large runoff volumes to nearby lowlands during the low-flow season when streamflow is critical to downstream water supplies. The potential for TWS from GRACE (Gravity Recovery and Climate

Isolating the impacts of land use and climate change on streamflow [PDF]

Hydrology and Earth System Sciences, 2015
Quantifying the isolated and integrated impacts of land use (LU) and climate change on streamflow is challenging as well as crucial to optimally manage water resources in river basins.
