Predicting snow cover dynamics and relevant streamflow due to snowmelt is a challenging issue in mountainous
basins. Spatio-temporal variations of snow extent can be analyzed using probabilistic snow cover maps derived from
satellite images within a relatively long period. In this study, Probabilistic Snow Depletion Curves (P-SDCs) and Probabilistic
Snow Lines (P-SLs) are acquired from Moderate Resolution Imaging Spectroradiometer (MODIS) cloud-filtered
daily snow cover images. Analyses of P-SDCs show a strong correlation with average daily runoff (R2 = 0.90) and temperature
(R2 = 0.96). On the other hand, the challenge lies in developing noteworthy methods to use P-SDCs in streamflow
estimations. Therefore, the main objective is to explore the feasibility of producing probabilistic runoff forecasts
with P-SDC forcing in a snow dominated basin.
Upper Euphrates Basin in Turkey has large snow extent and high snowmelt contribution during spring and summer
periods. The melting characteristics are defined by P-SDCs using MODIS imagery for 2001–2012. The value of snow
probability maps on ensemble runoff predictions is shown with Snowmelt Runoff Model (SRM) during 2013–2015
where the estimated runoff values indicate good consistency (NSE: 0.47–0.93) with forecasts based on the derived
P-SDCs. Therefore, the probabilistic approach distinguishes the snow cover characteristics for a region and promotes a
useful methodology on the application of probabilistic runoff predictions especially for snow dominated areas.
