Popis: Recent researches have suggested that atmospheric depositions are a major source of nutrients to aquatic ecosystems. It is important to identify and quantify nutrients deposited into surface water and the relationship with wind direction and wind speed to understand the contributing sources of nutrient deposition to Lake Kivu. This study analyzed the relationship of the contribution of TP and TN from the atmospheric deposition with wind direction and wind speed during the period 2017-2019 using regression analysis. Atmospheric deposition of nutrients (TP and TN) and lake water were analyzed in the laboratory for TP and TN using standard analytical methods. Wind speed (m/s) and wind direction (o) were collected at Lwiro station using automatic sensor and gaps were filled by data downloaded from NASA/POWER SRB/FLASHFlux/MERRA2/GEOS website. Temporal variation of TN and TP atmospheric deposition rates is significantly different over time (p
