Dynamic numerical simulation of water condition is useful for reservoir management. In developing countries, however, meteorological and hydrological time-series required for the numerical simulation are often unavailable. This paper presents a case study for generation of data absent at the Joumine Reservoir, Tunisia. Data of Wind Finder on web site and daily sunshine duration at the nearest weather stations were utilized for data generation of cloud cover and solar radiation being based on meteorological correlations found in Japan which is located in the same latitude as Tunisia. Time series of inflow water temperature was estimated from air temperature using a numerical filter expressed by a linear second-order differential equation. Numerical simulation by a vertical 2D turbulent flow model for stratified water body with the generated data successfully reproduced the seasonal thermal condition in the reservoir obtained with a thermistor chain for eight months in 2009.
