The aim of this thesis is to clarify the impact various flood control in extreme rainfall-runoff situations in an interest basin. For this purpose, for the catchment of Kopaninsky river has been set up hydrological model in Mike SHE application. Also have been executed scenarios of different flood control, which passed through the simulation in model Mike SHE. The resulting data from simulations serve as a basis for evaluating the effectiveness and applicability of scenarios for the catchment.

This thesis describes a study of the application of linear programming, a mathematical optimization technique, to the problem of operating a system of flood control reservoirs in the most efficient way for maximum flood peak reduction. The reservoir system studied was one which is proposed for flood control in the Fraser River Basin and for which preliminary designs have been made. The proposed sites are in the headwater areas of the river basin, remote from the area to be protected. A channel routing method which was linear was required for use with the linear programming technique. A method was developed which was based on monoclinal wave theory. Several different cases were studied in which the reservoir capacities and combinations of reservoirs included in the system were varied. The results show the maximum regulation which is available from each combination of reservoirs and identify the minimum storage capacities required at each site. Application of the technique in planning studies and in real-time reservoir operation is discussed. / Applied Science, Faculty of / Civil Engineering, Department of / Graduate

The model choice problem in Hydrology is illustrated by means of the optimum levee design for flat rivers along a confluence reach. Special attention is given to the selection of a probability distribution for the joint flood stages. The optimality criterion used is the minimization of construction plus expected flood damage costs. The main assumption in the mathematical model is that the levee profile is uniquely determined as a function of the levee heights at the extremes of the reach; thus the problem is reduced to the determination of the optimum pair of extreme levee heights. The selection of a probability distribution of flood stages, from a set of distributions estimated from the partial duration series, is performed using either one of two selection procedures: likelihood of the Chi -square statistic and sample likelihoods. A composite distribution, taking into account the model uncertainty, is also derived. The methodology presented is applied to the remodeling of the levee on the west bank of the Zagyva River, in Hungary. A sensitivity analysis is performed, using the best ranking distributions according to the two model choice procedures. The composite distribution appears to offer a reasonable choice.
