Modelling of hydrological rainfall-runoff processes is facilitated by the application of the systemtheoretical approach to linear, nonlinear and stochastic models. To this purpose, the variables involved in methods for determinating areal precipitation and baseflow separation are discussed. The convolution theorem in the theory of linear systems and the mathematical transform technique (Laplace-, Z-transformation) are used to identify characteristics of the watershed, and simulate hydrological processes. To support the calculation of model output functions, computer programs are included in the text. This volume is suitable as a text for hydrology courses at universities or engineering academies. 1 Introduction.- 2 Preparation of Hydrological Variables for Modelling.- 2.1 Mean Areal Precipitation.- 2.2 Baseflow and Runoff.- 2.3 Effective Rainfall.- 3 Treatment of Hydrological Variables in Linear System Models.- 3.1 System-Theoretical Elements.- 3.2 Concepts in Linear Systems.- 3.3 Treatment of Variables in the Time Domain.- 3.4 Treatment of Variables in the Frequency Domain.- 3.5 Particular Linear Systems (Conceptional Models).- 3.6 Identification of Linear Systems.- 3.7 Linear Systems with Stochastic Inputs.- 4 Treatment of Hydrological Variables in Non-Linear Systems.- 4.1 Volterra Series Model.- 4.2 Composition of Parallel Submodels.- Appendix 1 Program: PMSB1.- Appendix 2 Program: PMSB2.- Appendix 3 Program: PMSB3.- Appendix 4 Program: PMSB4.- Appendix 5 Program: PMSB5.- Appendix 6 Program: PREF1.- Appendix 7 Program: PREF2.- Appendix 8 Program: PREF3.- Appendix 9 Program: VAZAO1.- Appendix 10 Program: VAZAO2.- Appendix 11 Program: VAZAO3.- Appendix 12 Program: VAZAO4.- Appendix 13 Program: IDENT1.- Appendix 14 Program: IDENT2.- Appendix 15 Program: PCORR.
