Assessment of Irrigation Demands Based on Soil Moisture Deficits Using a Satellite-Based Hydrological Model

Remote Sensing, 2023
Soil moisture deficit is an essential element in the estimation of irrigation demands, both spatially and temporarily. The determination of temporal and spatial variations of soil moisture in a river basin is challenging in many aspects; however ...

Satellite-Based Evapotranspiration in Hydrological Model Calibration

Remote Sensing, 2020
Hydrological models are usually calibrated against observed streamflow (Qobs), which is not applicable for ungauged river basins. A few studies have exploited remotely sensed evapotranspiration (ETRS) for model calibration but their effectiveness on ...

Comparison of hydrological model ensemble forecasting based on multiple members and ensemble methods

Open Geosciences, 2021
Ensemble hydrologic forecasting which takes advantages of multiple hydrologic models has made much contribution to water resource management. In this study, four hydrological models (the Xin’anjiang model (XAJ), Simhyd, GR4J, and artificial neural ...

How do GPM IMERG precipitation estimates perform as hydrological model forcing? Evaluation for 300 catchments across Mainland China

Journal of Hydrology, 2019
Accurate precipitation estimates are essential for reliable hydrological simulations of fluxes and states. Satellite precipitation products have been widely used for hydrological applications, especially for ungauged regions.

Correcting the radar rainfall forcing of a hydrological model with data assimilation: application to flood forecasting in the Lez Catchment in Southern France [PDF]

, 2012
The present study explores the application of a data assimilation (DA) procedure to correct the radar rain- fall inputs of an event-based, distributed, parsimonious hy- drological model.

Early warning of shallow landslides: Monitoring of pre-failure suction-induced deformation [PDF]

E3S Web of Conferences
Most of the Landslides Early Warning Systems (LEWS) in operation are based uniquely on monitoring rainfall data, limiting their performance due to false alarms generated by rainfall thresholds.

Simulating interactions between saturated and unsaturated storage in a conceptual runoff model [PDF]

, 2003
There is an increasing demand for modelling the fluxes of chemical constituents at the catchment scale. Conceptual runoff models provide a basis for such modelling tasks provided that they capture the essential hydrological processes.

Attribution of runoff variation to climate and human-driven changes in the transition zone between the Qinling Mountains and the Loess Plateau under vegetation greening

Hydrology Research, 2022
The need for water safety management has increased in the transition zone between the Qinling Mountains and the Loess Plateau, China due to streamflow decline over the past 30 years. Vegetation greening, largely due to the result of the ‘Grain for Green’

Modeling Subsurface Hydrology in Floodplains [PDF]

Water Resources Research, 2018
AbstractSoil‐moisture patterns in floodplains are highly dynamic, owing to the complex relationships between soil properties, climatic conditions at the surface, and the position of the water table. Given this complexity, along with climate change scenarios in many regions, there is a need for a model to investigate the implications of different ...
