The study of the hydrologic cycle is physically focused on the analysis of the interactions between the soil surface (and specifically the soil water content, linked with precipitation) and the low atmosphere, which occur mainly through the mediation of the soil itself, the vegetation and the turbulent and radiative energy transfers which take place on the Earth's surface. In recent years, the hydrologic research has evolved towards a comprehensive theory describing the mass, energy and motion-quantity exchanges between surface and atmosphere at several scales. The practical aims of this efforts are: (1) to improve the mid- and long-term hydrologic forecasts; (2) to increase our capability of describing the impacts deriving from changes in the soil use and in the climate on the hydrologic cycle and on the Earth's ecosystems. The paper illustrate the implementation of GEOTOP, a distributed model of the hydrologic cycle which is meant to give a scientific contribution in this direction. GEOTOP is a terrain-based model, i.e. it is based on the employment of DEMs (digital elevation models); it is a distributed model, since all the simulated variables are returned for each pixel in the basin; it is a model of the hydrological cycle, in the sense that it simulates all the elements of the hydrological cycle, and not only the mass balance but also the energy balance: in fact the two balance equations are coupled by the evapotranspiration terms and by the soil temperature, which controls the soil hydraulic conductivity and the snow cover accumulation. As to the soil-atmosphere interaction, GEOTOP follows the treatment initially developed by Deardorf, and then implemented, with numerous changes, in land surface models either at global scale like BATS, NCAR-LSM, NOAH-LSM - or at larger scales like the VIC or at basin sclae like the DHSVM. The model adopts original solutions for the discharge calculation. In particular, it differs from the TOPMODEL, because it does not assume any stationeries conditions in the subsurface flows.

La modellazione idraulica dei fluidi bifasici solido liquido
Aronne, Armanini
TC160 Hydraulics
Sommario
Si propone una rivisitazione delle teorie bifasiche solido-fluido, applicate alle correnti idriche, con particolare riferimento alle correnti gravitazionali che interessano gli alvei a forte pendenza. Viene posta particolare enfasi al problema della coesistenza del regime frizionale e del regime collisionale.
Nella nota si riportano anche alcuni riscontri sperimentali delle più recenti teorie su questo particolare punto.
La nota è una relazione generale tenuta dall'autore al XXXII Convegno di Idraulica e Costruzioni Idrauliche, tenutosi a Palermo
nel settembre 2010.
Abstract
The paper presents an overview of the theories on two-phase (solid-fluid) approaches to the water flows, with particular reference to gravitative granular flows, affecting the mountain steep streams, such as debris flows.
Particular emphasis is given to the problem of the coexistence of the frictional regime and the collisional regime inside the same flow field.
The note reports also some experimental evidences of the most recent theories on this specific item.
The paper reports a keynote lecture given by the author at the XXXII Italian Congress of Hydraulics and Hydraulic Construction held in Palermo on September 2012.

Proceedings of the 17th International Workshop on Physical Processes in Natural Waters: PPNW2014, Trento, Italy, 1-4 July 2014
TC160 Hydraulics
The focus of the PPNW workshops is the physics of inland and coastal water bodies and their interactions with the physical and biogeochemical processes that control water quality, ecosystem function, and the services such systems provide. The workshops traditionally cover a broad spectrum of scientific topics. Besides general topics, the Trento workshop pays special attention to the coupling of
physical and ecological processes and water quality in alpine and perialpine lakes.
PPNW is an open workshop, actively seeking to expand contacts with neighbouring fields such as physical oceanography, the atmospheric sciences, and engineering. With 40 to 60 participants and a small number of invited speakers, the PPNW meetings are characterized by
their active workshop atmosphere and a comfortable time frame for presentations and discussion.
