Dalton Medal Lecture: How far can we go in distributed hydrological modelling? [PDF]

open access: yes, 2001
This paper considers distributed hydrological models in hydrology as an expression of a pragmatic realism. Some of the problems of distributed modelling are discussed including the problem of nonlinearity, the problem of scale, the problem of ...

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

open access: yesRemote 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 ...

A physically-based parsimonious hydrological model for flash floods in Mediterranean catchments [PDF]

open access: yes, 2011
A spatially distributed hydrological model, dedicated to flood simulation, is developed on the basis of physical process representation (infiltration, overland flow, channel routing).

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

open access: yesE3S 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.

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

open access: yesOpen 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 ...

A goodness of fit measure related to r² for model performance assessment [PDF]

open access: yes, 2013
Checking the predictive worth of an environmental model inevitably includes a goodness of fit metric to quantify the degree of matching to recorded data, thereby giving a measure of model performance. Considerable analysis and discussion have taken place

Assessing the influence of the Merzbacher Lake outburst floods on discharge using the hydrological model SWIM in the Aksu headwaters, Kyrgyzstan/NW China [PDF]

open access: yes, 2013
Glacial lake outburst floods (GLOF) often have a significant impact on downstream users. Including their effects in hydrological models, identifying past occurrences and assessing their potential impacts are challenges for hydrologists working in ...

Present and future of hydrology

open access: yesWater Science and Engineering, 2013
The complexities of hydrological phenomena, the causes that lead to these complexities, and the essences and defects of reductionism are analyzed. The driving forces for the development of hydrology and the formation of branch subjects of hydrology are ...

Application of SWAT Model for Simulating Monthly Runoff, Lake Urmia Watershed in Kurdistan Province, Iran [PDF]

open access: yesمحیط زیست و مهندسی آب, 2020
The Soil and Water Assessment Model (SWAT) is a continuous and semi-distributed model. The SWAT model is capable of being connected to the Geographic Information System (GIS).
