Comparison of Process-Based and Temperature-Index Snowmelt Modeling in SWAT

Abstract: Snowmelt hydrology is an important part of hydrological analyses where significant proportion of precipitation is expected to fall in a snow form. Many models have long been introduced to enable the simulation of snowmelt processes in the watershed ranging from simple temperature based equations to complex and sophisticated process-based equations. Usually, mixed results have been reported whether or not the difference between results achieved by incorporating data demanding models vis-à-vis simple temperature… Show more

“…Daily SWE was modeled at the site from 1970 to 2012 using a form of the soil water assessment tool (SWAT) temperatureindex snowfall-snowmelt model (27) with modifications to the calculation of a snowmelt rate factor (37). Model parameters were calibrated to 23.5 y (1989-2012) of daily SWE observations from a nearby snow telemetry (SNOTEL) weather station 25 km to the west (Table S4).…”

“…Although the first is more physically based it requires more input variables, whereas the latter uses more readily available variables. Comparisons of the two methods have found insignificant differences in the melted water calculated (Kustas et al, 1994;Debele et al, 2010). However, the site-specific degree-day parameters need to be assessed (Bentsson, 1984).…”

“…Protecting these water resources is an emerging global challenge. Different models ranging from normal temperature-index-based algorithms to complex algorithms have been used to predict snow and glacier melting processes in the region [3] where snow and glacier melt provides stream flow for the Indus river system. Pakistan's northern mountainous part, known as Gilgit-Baltistan (GB) with a varying elevation (2000 m to 8611 m above sea level) and unique glacier and snow cover dynamics, offers exclusive opportunities and challenges for researchers to better understand the hydrological processes occurring in the region.…”
