TLDR
In this paper, the equations describing water movement in a dry snow cover are derived, and examples of flow through ripe, refrozen, and fresh snows are given, showing that the grain size of snow has a large effect on the timing of water discharge.
Abstract
The equations describing water movement in a dry snow cover are derived, and examples of flow through ripe, refrozen, and fresh snows are given. The grain size of snow has a large effect on the timing of water discharge. Water is retained by dry snow to raise its temperature and satisfy the irreducible water saturation. These requirements delay and reduce runoff following rain on dry snow.

A theory for the scalar roughness and the scalar transfer coefficients over snow and sea ice

TL;DR: In this article, the authors present a theoretical model that predicts neutral-stability values of CH and CE as functions of the wind speed and a surface roughness parameter, which is used to establish the interfacial sublayer profiles of the scalars, temperature and water vapor, over aerodynamically smooth and rough surfaces.

Slower snowmelt in a warmer world

TL;DR: The authors showed that shallower snowpack melts earlier, and at lower rates, than deeper, later-lying snow cover, and that the fraction of meltwater volume produced at high snowmelt rates is greatly reduced in a warmer climate.

Wetting front advance and freezing of meltwater within a snow cover: 1. Observations in the Canadian Arctic

TL;DR: In this paper, the authors showed that when the wetting front reached premelt stratigraphic horizons, water ponded at the interface and then flow fingers developed and penetrated the lower stratum.

Retention of Greenland runoff by refreezing: Implications for projected future sea level change

TL;DR: In this paper, a model is presented which describes in a simple way the transient process of infiltration, refreezing, and runoff in a future warming climate, applied to Greenland, for which predictions of runoff-induced sea level rise that do not consider the residual water content of the firn are as much as 5.0 cm too high over 150 years.

The transmission of water through snow

TL;DR: In this paper, an instrument which makes use of the difference in the dielectric constants of ice and water was constructed and used to detect small changes in the liquid water present in a snow pack.

The capillary effects on water percolation in homogeneous snow

TL;DR: A theoretical basis for introducing capillary effects into the theory of water percolation through snow is given in this article, where a capillary pressure-liquid saturation relationship found in the laboratory is used together with the theory to make a quantitative examination of capillary effect.

A theory for water flow through a layered snowpack

TL;DR: In this paper, a natural snowpack with ice layers is described in terms of an equivalent anisotropic porous medium, represented as a diagonalized matrix whose principal values can be calculated from a small amount of information about the prototype snowpack.

The dynamics of liquid water in deep snow-packs

TL;DR: In this article, the hydromechanic and dynamic potentials which influence the retention and discharge of water by the snow-mantle have been studied and a solution of the snowmelt problem which will improve the forecasting of floods as well as forecasting of agricultural and industrial water-supplies is proposed.
