Calibration of conceptual models for rainfall-runoff simulation
Conceptual mathematical models are a useful tool for rainfallrunoff modelling of a basin. The calibration of such models has attracted the attention of a number of hydrologists since unique and optimal parameters are difficult to obtain. The calibration of a conceptual model is discussed through a simple conceptual model whose parameters are determined using a search technique. It is shown that...
متن کاملRegionalisation of Rainfall-Runoff Models
A new approach to regionalisation for prediction of flow characteristics in ungauged catchments is presented. If flows in ungauged catchments are to be predicted using calibrated rainfall-runoff models, regional relationships between the parameters of such models and catchment attributes must be determined. This is only possible with parsimonious models (fewer than about 7 parameters), and even...
متن کاملDevelopment of a simple, catchment-scale, rainfall- evapotranspiration-runoff model
Representation of the hydrological interaction between the land surface and the atmosphere requires considerable improvement, particularly for predicting evapotranspiration feedbacks for use in models of the general circulation (GCMs) of the atmosphere. The predictive model developed here attempts to use a water balance approach that extracts information from the masses of catchment-scale time ...
متن کاملConceptual runoff models - fiction or representation of reality ?
Seibert, J., 1999. Conceptual runoff models fiction or representation of reality? Acta Univ. Ups., Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 436. 52 pp. Uppsala. ISBN 91-554-4402-4. Available observations are often not sufficient as a basis for decision making in water management. Conceptual runoff models are frequently used as tools for a wide ...
متن کاملFuzzy committees of specialised rainfall-runoff models
This discussion paper is/has been under review for the journal Hydrology and Earth System Sciences (HESS). Please refer to the corresponding final paper in HESS if available. Abstract Often a single hydrological model cannot capture the details of a complex rainfall-runoff relationship, and a possibility here is building specialised models to be responsible for a particular aspect of this relat...
