Fuzzy committees of specialized rainfall-runoff models: Further enhancements and tests

Kayastha, N. (author), Ye, J. (author), Fenicia, F. (author), Kuzmin, V. (author), Solomatine, D.P. (author)

Often a single hydrological model cannot capture the details of a complex rainfall–runoff relationship, and a possibility here is building specialized models to be responsible for a particular aspect of this relationship and combining them to form a committee model. This study extends earlier work of using fuzzy committees to combine...

Geometric dependency of Tibetan lakes on glacial runoff

Phan Hien, V. (author), Lindenbergh, R.C. (author), Menenti, M. (author)

The Tibetan Plateau is an essential source of water for Southeast Asia. The runoff from its ~34 000 glaciers, which occupy an area of ~50 000 km2, feeds Tibetan lakes and major Asian rivers like the Indus and Brahmaputra. Reported glacial shrinkage likely has an impact on the runoff. Unfortunately, accurate quantification of glacial changes is...

Data compression to define information content of hydrological time series

Weijs, S.V. (author), Van de Giesen, N.C. (author), Parlange, M.B. (author)

When inferring models from hydrological data or calibrating hydrological models, we are interested in the information content of those data to quantify how much can potentially be learned from them. In this work we take a perspective from (algorithmic) information theory, (A)IT, to discuss some underlying issues regarding this question. In the...

Investigating the dynamics of bulk snow density in dry and wet conditions using a one-dimensional model

De Michele, C. (author), Avanzi, F. (author), Ghezzi, A. (author), Jommi, C. (author)

The snowpack is a complicated multiphase mixture with mechanical, hydraulic, and thermal properties highly variable during the year in response to climatic forcings. Bulk density is a macroscopic property of the snowpack used, together with snow depth, to quantify the water stored. In seasonal snowpacks, the bulk density is characterized by a...
