Investigation of empirical relationships for flood peak estimation in Cyprus

This project arose after a personal consultation with the officials of the Water Development Department of Cyprus and is a subject of particular interest to hydrologist engineers. Although the methodologies proposed are at a primary stage, it seems possible to give acceptable estimates concerning the calculation of flood peaks, taking into consideration that the proposed methodology for estimating the time of concentration, is based on field data obtained from the area to which they refer. The project can be divided into two subsections. The first section is basically the editing of raw data (which are: series of monthly pick flows and maps of surface physiographic characteristics of the island as land use, terrain model, geological formations, etc.) as well as the production of new maps (runoff curve number map, flow coefficient map), the choice of the suitable river basins for data processing and also the estimation of hydrological characteristics of these basins. The second section presents the processing of the hydrological calculations results. This section focuses mainly on the investigation of whether the existing equations for the time of concentration adjust well to the data taken from hydrological basins of Cyprus. Furthermore, in this section new empirical formulas for calculating the time of concentration are examined arising solely by linear regression and optimization of Cyprus field data. Finally, a methodology for the estimation of the flood peaks in Cyprus basins, is proposed.
