A Comparison of Simple Snowmelt Models for the Ane River Basin

Synopsis The objective of the present work was to develop and compare simple snowmelt model formulations using data from the Ane River Basin. The model comparison was done using winter 2001-2002 data from the Surumi station, located in the Ane River Basin, Northeast part of Lake Biwa. A temperature-index and a enhanced temperature-index (including income shortwave radiation) models were applied to the data considering different time resolutions. The results show that the empirically derived base model using hourly time steps had a good agreement with the data. Apparently, using hourly data to go to a finer resolution of 10 minutes data could be used without so much error arising from the simulation. The Enhanced Temperature-index compared to the other models showed little to no improvement.
