The results showed that: (1) TRMM data were very useful for hydrological simulation in high and cold mountainous catchments (2) precipitation was the primary contributor nearly all year round, reaching 56.5% of the total runoff on average (3) groundwater occupied the biggest proportion during dry seasons, whereas snowmelt made a substantial contribution only in late spring and summer and (4) hydrological signatures were useful for helping to evaluate the performance of the hydrological model. Hydrological signatures were finally used to help identify if the hydrological model simulated total runoff and corresponding proportions properly. The uncertainty in runoff proportions from precipitation, snowmelt, and groundwater was quantified by a batch-processing module. Tropical Rainfall Measuring Mission (TRMM 3B42V7) data were utilized as a substitute for gauge-based rainfall data, and the capability of simulating precipitation, snow, and groundwater contributions to total runoff by the Soil and Water Assessment Tool (SWAT) was investigated. In this work, one tributary of the Yarlung Zangbo River Basin (the upper stream of the Brahmaputra River) was used as a case study for hydrological modeling. Meanwhile, hydrological modeling is challenging due to parameter uncertainty. However, lack of data in these mountainous catchments prevents full understanding of the response of hydrology or water resources to climate change.

For average runoff over Greece, draining to different parts of the Mediterranean Sea, both drivers have contributed more or less equally to a considerable total decrease of −75 ± 10 mm/year.
We find that the precipitation change has driven decrease while the irrigation development has driven increase in evapotranspiration, leading to a net total increase of 26 ± 7 mm/year on average over Greece. Changes are assessed from an early (1930–1949) to a recent (1990–2009) period, with different climate (particularly less precipitation) and human influence (particularly more irrigated agriculture) conditions in the latter. We synthesize climate, hydrological, and human land- and water-use data with the aim to decipher key changes and their drivers for freshwater availability and flux balance in five nested catchments across Greece.
