Abstract. Flow duration curves are simple and powerful tools to deal with many hydrological and environmental problems related to water quality assessment, water-use assessment and water allocation. Unfortunately the scarcity of streamflow data enables the use of these instruments only for gauged basins. A regional model is developed here for estimating flow duration curves at ungauged basins in Sicily, Italy. Due to the complex ephemeral behaviour of the examined region, this study distinguishes dry periods, when flows are zero, from wet periods using a three parameters power law to describe the frequency distribution of flows. A large dataset of streamflows has been analysed and the parameters of flow duration curves have been derived for about fifty basins. Regional regression equations have been developed to derive flow duration curves starting from morphological basin characteristics.

The Cost

Hydrologic variables such as available flow for electrical generation and its time distribution, together with flood magnitudes, represent the basis for evaluation of potential hydro sites. Economic viability, especially for small-scale hydro sites is very sensitive to these basic hydrologic variables. Unfortunately, many potential small-scale hydro sites are located on ungauged streams and often the cost of deriving the necessary site specific hydrologic information for design is prohibitive in relation to overall project costs. Therefore, regional techniques have been developed for evaluating the necessary hydrologic variables at a prefeasibility level for small-scale ungauged sites anywhere in Canada. Studies concerned with developing regional techniques for application to feasibility level evaluations have been completed for Atlantic Canada, British Columbia, and Ontario.The methodology can be used to estimate the flow duration curve and the turbinable flow curve for ungauged streams. Equations relating characteristics of the curves to physiographic and climatic parameters have been derived for eleven regions across Canada. An example demonstrating application of the new methodology is included. Key words: hydroelectric power, small-hydro, regional hydrology, ungauged streams, flow duration curves, turbinable flow curves.
