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...

Empirical study of nonlinearity in direct runoff on a 100 km 2 basin

One of the scale problems in hydrology is to relate nonlinearity in basin response to size and other factors. On the Sputka basin (103.4 km), three groups of unit hydrographs were identified, each group having a common shape parameter, TV, of the Nash model and each, therefore, representing one dimensionless response. The existence of the three dimensionless responses can be explained in the fi...

Evaluation of monthly runoff estimated by a rainfall-runoff regression model for reservoir yield assessment

Results of further evaluation tests of a monthly rainfall-runoff model used for extending streamflow data records in England and Wales are presented. In particular, since the objective of the record extension exercise was to make available long enough data records for reservoir yield assessment, model performance in reproducing the reservoir storage-yield-reliability relationship during calibra...

Changes in flood regime by use of the modified curve number method

This paper describes the use of a simple two stage rainfall-runoff model in which a curve number (CN) principle is used to calculate the soil water content and, subsequently, the rainfall contribution to direct runoff and groundwater flow. The maximum soil water retention, S, is used to express various characteristics of a catchment (infiltration rate, soil cover and land use, as in the CN meth...

Regional rainfall and flood frequency analysis for Sicily using the two component extreme value distribution

This paper first presents a duration-dependent hypothesis regarding the parameters of the two component extreme value (TCEV) distribution and proposes a simple model to obtain the rainfall depthduration relationship both at ungauged sites and at short record gauged sites in the Sicilian region. Then, by using the annual maximum peak flood and the annual maximum mean daily discharge recorded in ...
