Abstract: Assessment of the hydrological parameters of the Kalako waterfall on the Tinkisso-Dabola River by the 42-year data reconstruction method from 1971 to 2012. The year of calculation of hydrological parameters is 1989. The values of hydrological parameters (precipitation heights, flow volume and monthly flow) in this year from the site of Kalako determined, are zero in the months of December, January and February. They are minimal during the months of February (8.0 mm, 2.72×106 m3 and 1.04 m3/s), April (29.1 mm, 9.89×106 m3 and 3.81 m3/s) and November (8.9 mm, 3.02×106 m3 and 1.16 m3/s). This results in a very small amount of water during these periods. On the other hand, during the period from May to October, the hydrological parameters of the site are important, with the maximum values observed in September (333.42 mm, 113.02×106 m3 and 43.75 m3/s). These results show that, during the year of calculation, seven (7) months (April, May, June, July, August, September and October) out of twelve (12) of the Kalako site are very favorable for the production of hydroelectric power.Abstract: Assessment of the hydrological parameters of the Kalako waterfall on the Tinkisso-Dabola River by the 42-year data reconstruction method from 1971 to 2012.
