Comparative study of ecohydrological streamflow probability distributions

Porporato, Amilcare (AMER GEOPHYSICAL UNION, 2010)

We run a comparative study of ecohydrological models of streamflow probability distributions (pdfs), p(Q), derived by Botter et al. (2007a, 2009), against field data gathered in different hydrological contexts. Streamflows ...
Effect of different jump distributions on the dynamics of jump processes

Porporato, Amilcare (AMER PHYSICAL SOC, 2010)

The paper investigates stochastic processes forced by independent and identically distributed jumps occurring according to a Poisson process. The impact of different distributions of the jump amplitudes are analyzed for ...
Impact of stochastic fluctuations in storage-discharge relations on streamflow distributions

Porporato, Amilcare (AMER GEOPHYSICAL UNION, 2010)

In this paper we extend recent theoretical results on the structure of the probability density function of streamflows forced by stochastic rainfall sequences. Our extension is aimed at incorporating an additional, independent ...
Stochastic modeling of soil salinity

Porporato, Amilcare (AMER GEOPHYSICAL UNION, 2010)

A minimalist stochastic model of primary soil salinity is proposed, in which the rate of soil salinization is determined by the balance between dry and wet salt deposition and the intermittent leaching events caused by ...
