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 کاملComparing several genetic algorithm schemes for the calibration of conceptual rainfall-runoff models
The Genetic Algorithm (GA) is often associated with local search optimisation techniques in the calibration process of Conceptual Rainfall-Runoff Models (CRRMs) (Wang, 1991; Franchini, 1996), i.e. the GA is used for approaching the region encompassing the global solution and then its results are used as a starting point for the local optimizer in the subsequent "fine-tuning" process. However, t...
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 کاملUse of a genetic algorithm combined with a local search method for the automatic calibration of conceptual rainfall-runoff models
Wang (1991) reported that a genetic algorithm (GA), combined with a local search method, is an efficient and robust means for the calibration of conceptual rainfall-runoff models. In this article Wang's genetic algorithm has been slightly modified in order to improve its efficiency. The "optimal parameter set" produced by the G A has then been used as the starting point for a local optimization...
