Baldocchi's Classics

I took the  freedom to reproduce Dennis Baldocchi's classic. The original post is on his website to which I dedicated another post. A must for who is interested in Soil-Vegetation-Atmosphere interactions.  I just added the link to the publications (on the title when pdf is open).
As a post of mine, it can be seen as a companion of the two recent posts on plant-atmosphere interactions where further references are presented (I and II).

Estimating water budgets with JGrass-NewAGE

We already talked about water budgets, and the papers of ours that deals with it (see below). Because in this Fall AGU meeting there was a dedicated session, we presented an abstract:

Recently we presented two papers one dedicated to the estimation of the water budget components in a small, basin, the Posina catchment [Abera et al., 2017], and the other in a large basin, the Blue Nile [Abera et al., 2017b]. Closing the budget in the two cases was different. Worth to say, it was much more difficult to close the budget at Posina, since at the large scale satellite platform can reasonably help to validate the results. At the smallest scale ground measurements usually available do not guarantee the closure of the budget without making additional hypothesis and remote sensing data cannot give very much help.  The hypothesis that we made is that the groundwater storage comes back to the initial level after a certain time, that we called Budyko time, TB. This time can be fixed arbitrarily, for instance, to five years and then varied to assess, through these trials the uncertainty of the budget. The large scale case was largely supported by remote sensing data, instead, either for calibration and/or validation. This contribution explains how we actually did, clarifies some aspects of the informatics necessary to obtain it and openly discusses the issues risen in our work. We also consider varying configuration of the water budget schemes at the subbasin level, and how this affects the estimates.
Finally we analyse the problem of travel times [e.g. Rigon et  al., 2016a, Rigon et al, 2016b]  as it comes out from considering the multiple fluxes and storages and discuss how much they can be realistic. All considerations and  simulations are based on the JGrass-NewAGE system [Formetta et al., 2014] and its evolution presented in Bancheri [2017].

As we say in the presentation, we could not talk about the travel times. However there are several other places where you can find about, here. 
Clicking on the above Figure, you will see the presentation that was used in NewOrleas. However, on Youtube, we uploaded an extended version with comments.

So finally, I was obliged to try to understand what Copulas are. Put it simply. They are functions that connect marginal distributions to their multivariate distribution. Sklar (1959) theorem shows that the copula exists and is unique for any pair. Restricting to bivariate distribution function for sake of simplicity, Sklar theorem establish that the joint cumulative distribution $H(x,y)$ of any pair of continuous random variable (X,Y) may be written as as:
H(x,y) = C(F(x),G(y)) \ \ \ \forall x, y \in \mathbb{R}
where $F(x)$ and $G(y)$ are the marginal distributions of $X$ and $Y$. $C$, the copula, can be though as a function such that:
C:\, [0,1]^2 \mapsto [0,1]

Obviosly just in the Platonic world where you know $H$,$F$ and $G$, you can determine the unknown $C$. In practice you work with much less information, where you have the marginals, $F$ and $G$ and, maybe some information about the correlation of the random variables they describe.
So you have to infer the multivariate distribution, by selecting, as usual I would say, the copulas among a large set of copulas templates.
This is what is written for instance in Genest and Favre 2007, a paper particularly directed to hydrologists. So, for your introduction to Copulas you can probably start from that paper. However, I came to it, by its citation in Ebrechts, 2009. Traditional references on the subject are the books by Joe (1997) and Nelsen (1999) but a nice review paper (therefore more synthetic) is Frees and Valdez 1998.
Particularly relevant copulas are useful to understand correlations among variables, and the so called empirical copulas (e.g. Genest and Favre, 2007) can be used to this scope.
Among Hydrological application, I can mention, among others, De Michele and Salvadori (2002), Salvadori and De Michele (2004), Grimaldi and Serinaldi (2006), and Serinaldi et al., 2009.

On Complex Network Representation and Computation of Hydrological Quantities

Francesco Serafin participated for us to the AGU fall meeting presenting part of his work. They gave him a poster, actually the poster whose image is below. It is about the representation of Hydrological models as a network of interactions.

You can access a more readable version of the poster by clicking on the Figure. A similar, more recent presentation, given for IEMSS 2018 at Fort Collins can be found below:

Marialaura Bancheri defense

The Ph.D. Thesis of Marialaura Bancheri is already available in a previous post. On december 14, she finally defended it. This is the video of her performance. Her topics are: research reproducibility, GEOFRAME, reservoir based modelling (or semidistributed modelling) of the hydrological cycle, travel times theory re-interpreted in the perspective of reservoirs modelling.

I have no doubt that it could be very useful to all who are interested in our recent work and to all those that try to interpret catchment scale behavior through travel times. Marialaura was an outstanding student, is an exceptional team manager, and she is looking for an appropriate post-doc position.

Monday's discussion on evapotranspiration - Part II - The soil-plants fluxes

The first post treated transpiration from the point of view of the atmosphere control volume. There is a “below” though. Below is composed by leaves, trunks/stems, roots. Roots, in turn, are being inserted in soil from where they sip water and nutrients.
Water in soil is understood to be moved by Richards equation (with all the possible variations or extensions), essentially a Stokesian flow (therefore laminar) in the bundle of soil pores.
Plants do not have a pumping heart and therefore has been since long time argued how they can move water up until the tallest leaves that, can be as high as 150 m above soil level. Some plants do not have either a real “vascular” system in the sense we mean for animals, with arteries and veins. They have indeed specialised interconnected cells to move water up, called collectively xylem, and specialised interconnected cells to move around sucrose and the products of photosynthesis (especially to fruits and roots) called phloem.

So the xylem is the place were to look for ascending water. But how water moves in it ? Since Hales (1727), reported in Holbrook and Zwieniecki (2005), the theory invoked was the cohesion-tension one, which is well illustrated in the introduction of e.g. Holbrook and Zwieniecki (2005), which is open (on Amanazon). Other references include Tyree (2003), which is satisfying from the conceptual point of view but not from the point of view of equations. From this side, possibly Steudle (2001) and Strook et al., (2014) are better. Also Pickard (1981) remains a good reference.
The problems to be understood in xylem water movement is how cohesion-tension works. Under normal conditions, atmosphere is very arid and, for instance at normal temperatures, assuming a 50% of specific humidity of air, it correspond to a pressure of -100MPa (e.g. Jensen at al, 2016), while at roots is usual conditions, water is at much higher pressure, ~ -1.5MPa, meaning, that the gradient of pressure along a plant of ten can be as high are 10 MPa/m (see also Nobel, 2009).
Therefore water is “pulled” and we have to face with the counterintuitive idea that water resist to a tension. For liquids to resist to tensile forces, it is necessary that no bubble is nucleated inside the liquid that disrupt the liquid continuity (creating emboli, e.g. Fsher, 1948). Eventually mechanisms for refilling the vessels have also to be required for understanding the real functioning of plants. This is actually matter of research.
Very much attention to the physics of the process, is also paid in the recent review by Jensen et al, (2016). There also the phloem flux is covered with quite detail and reference therein is large and up-to date. Reading the papers I cited, that are just a few in my collection, can be a starting point for understanding the problem, and this is an advise that I am experimenting myself.
Personally, being highly ignorant of plants physiology, I also require to study it overall. A reference I am following is a classic textbook, Taiz and Zeiger (2002), but a more physical-chemical-mathematical approach ca be found in Nobel (2009).
My first look at the above papers make me remain with the idea that too details hide a possible, more integrated and macroscopic treatment of the matter, at level of single tree, without having necessarily to cope with each cellular movements of water. In fact a look to plants functioning as a whole, is what we, hydrologists are looking for.
Concentrating on plants does not mean we have the whole picture, since soil-plant(s) interactions must be accounted for. We already said that, especially in this case, Richards equation is considered the equation describing water flow in soil. Richards equation, however, is a partial differential equation, ideally written at the Darcy scale, while soil-water-plant interactions happen at the smallest scale of roots. Pickard (1981) gives a description of roots structure but this is therefore not enough to understand well what happens. Soil scientists are bold, and therefore they use a sort of brute-force attack to the problem, where the Darcy scale is ignored and Richards equation is used at small scale where one root link can be associated “mechanistically” to an elementary control volume. A good and up-to-date illustration of this approach is given, for instance in Schröder (2013) Ph.D. Thesis. The only trick used to differentiate the usual approach for adapting it to root interactions is to add two type of conductivities. But please read Schröder (2013) and Huber et al. (2014) to have full and detailed account of it. Companion to this approach is the use of some root model, for instance as Root Typ (Pagès et al., 2004). The latter model are useful also alone, cause the information they contain of roots architecture and density, factors that certainly any theory cannot neglect.

So, I hope to have indicated some initial lectures of which you find the reference below. Below below you also find a bunch of other references, some from the same Authors, that could probably be a good second lecture.

Krigings paper

Finally we submitted the Kriging paper. Interpolation of hydrological quantities is a necessity in hydrological modeling. Since the beginning of last century, various techniques were implemented to obtain it:
or other types of interpolation 

We prefer Kriging. This paper accounts for the implementation of Krigings inside the JGrass-NewAGE system

The paper can be seen here. However, you can find all the material of the paper on the OSF platform. We tried to share everything from code to data and even the simulation we have performed. Therefore, in principle, any reader could try our software and reproduce our result.
