What is C3A (In Italian) ? My presentation to the students of Viticulture and Oenology of the Center of Agricolture, Food and Environment of the University of Trento

This is an unusual topic for the blog. Because it happens that I am the director of the Centro Agricoltura, Alimenti, Ambiente of the University of Trento, in my academical duties there is also to present to students what our Center is about.  You can find the presentation in Italian clicking on the Figure below.

The research program (in English) of the Center can be found also in another post, here.

MARRMOT (and others) models represented using the Extended Petri Nets

 This is a place holder - Document still missing

The draft presented in this post represents all the MARRMoTs hydrological models using the Extended Petri Nets graphs. This show in practice that the statement that all the integral distributed hydrological models  (a.k.a. lumped distributed models, the hydrological dynamical systems, semi-distributed hydrological models) can be represented by means of the EPN is actually true. 

The MARRMoT (Modular Assessment of Rainfall-Runoff Models Toolkit) is a collection of hydrological models designed to simulate rainfall-runoff processes across different scales and conditions. Developed in MATLAB, MARRMoT provides a modular framework that allows researchers to compare, assess, and implement various conceptual hydrological models consistently

Key Features and Purpose:

• Model Variety: MARRMoT includes 47 different rainfall-runoff models, ranging from simple lumped models to more complex, semi-distributed structures.
• Comparative Framework: Its standardized environment enables researchers to test models on the same data sets and conditions, making it easier to assess model performance, suitability, and sensitivity.
• Customization: Users can adapt model configurations or modify parameters within the toolkit to better fit specific research objectives or study basins.
• - Open-source and Accessible: MARRMoT is open-source, encouraging community contributions, modifications, and application across various hydrological research areas.

This toolkit is particularly useful for researchers looking to improve or validate hydrological models and for those who want a structured way to compare the effects of model structure on hydrological simulation outcomes.

Extended Petri Nets (EPNs) are an enhanced version of traditional Petri Nets, a mathematical modeling language originally designed to describe distributed systems with concurrent, asynchronous processes. EPNs incorporate additional features to increase modeling flexibility and allow for more complex system representations. In scientific modeling, they are used for representing and analyzing systems in which discrete and continuous interactions are critical, like biological networks, chemical reactions, ecological models, or engineering processes.

In hydrology, an EPN might represent a soil-plant-atmosphere model, where state variables (such as soil moisture or leaf temperature) are stored in places (nodes) and fluxes (like water or energy flow) are represented as transitions. The EPN structure could allow the model to account for dependencies like temperature effects on transpiration, thus helping visualize and simulate complex feedbacks and interactions in the water cycle.

Two possibile positions, if the right people show up

We are once again looking for exceptional individuals to join our team for PhD (3 years) or postdoc (2 years) positions.

Position 1: GEOframe-NewAGE System Application and Methodologies to build a Po Digital Twin

This role focuses on the implementation and application of the GEOframe-NewAGE system to the Po River Basin. You will assist the team in finalizing the calibration and analysis of the hydrology of the Po catchment for the period 1990-1991, with exciting outcomes expected in climatology, drought studies, and hydroinformatics applications. This project is not purely applicative as it may initially seem. It aims to encompass numerous methodological aspects and offers a wealth of research opportunities, along with the data needed to pursue them.

Position 2: Earth Observations and GEOSPACE System Development

This position focuses on integrating Earth Observations into the GEOSPACE system, with further development and applications in the Po River Basin and the Val di Non (Noce River catchment). The primary objective is to advance the integration of high-resolution remote sensing with hydrological modeling, while also improving our land-surface modeling capabilities. The role involves exploring and testing various transpiration models, incorporating increasing levels of physical realism and plant physiology to enhance model reliability.

We encourage interested candidates to explore my blog, where you’ll find detailed information about our working methods, the tools we use, and the philosophy we follow. An insightful candidate will recognize how well we might work together by reviewing the contents they find.

Rules of the (ECHO) house (or what the Ph.D.s and postdoc should do) by Andrea Rinaldo

 

The Rivers' Speech

Andrea Rinaldo is retiring. So young and strong I would say, he is only seventy  now  (seventy is the new forty, at least for him) and he will certainly continue to produce. Therefore the University of Padova is celebrating him on Friday, September 27 afternoon. He will talk about University and eventually some of his direct students, part of a family which now has grew wide and international, were asked to highlight for the general audience (in Italian) Andrea's research.  

My topic was, quite obviously, geomorphology and river networks. Clicking below the figure you can find what I prepared in Italian (pre-recorded video here). Below The  English version is here (pre-recorded video here). It is a short talk (8 minutes or so, but I hope that you like it). The complete records of the event in honor of Andrea Rinaldo can be found on YouTube.

A new way of discussing on the web with a distributed responsability

As many of you may know, recently, Jan Seibert issued an appeal to young hydrological researchers, advising caution when accepting invitations to become editors for review issues. In the past, these invitations were broadly distributed, but the results were often disappointing, leading to wasted time and effort. Demetris Koutsoyiannis, among others, raised opposing viewpoints, shifting the focus to the broader issues within scientific publishing and the influence large publishers can exert on the development of science.

This appeal was somewhat unusual for the AboutHydrology mailing list, which typically serves as an announcement platform, not a forum for discussion. Nevertheless, the topic quickly gained traction (considering the size of the community), with several prominent scientists contributing to the conversation. I eventually had to close the discussion within a day to prevent it from becoming overly repetitive. Despite its brevity, the conversation provided a good overview of the relevant perspectives.

### Key Takeaways:

1. Moderating a discussion list is surprisingly overwhelming.

2. A mailing list isn't the ideal platform for synthesizing differing opinions, but it can at least offer a quick overview of diverse perspectives on a given topic.

3. After a certain point, even well-informed and motivated contributions stop adding significant value.

4. Finding a suitable platform for discussion is essential.

5. A mailing list, despite its origins in fostering debate (like the old listserv model), is not the right tool for this anymore. Today, there are better alternatives.

Moderating such discussions is demanding, and moderators may not always have a vested interest in the topic. My proposed solution is a more distributed approach, where people can raise a question in a specialized application and share a link for feedback, allowing engagement without requiring users to join the application itself. The person who raises the question would be responsible for moderating that particular thread.

The ideal platform for AboutHydrology would be a tool designed for question pooling—something like an evolved version of *Klicker*, developed by the University of Zurich, where Jan works. *Klicker* allows questions to be posed and moderated, and users can respond via a shared link. This setup would allow the questioner to create a poll, share it on AboutHydrology, and gather feedback. At the end of the process, a report summarizing the responses could be distributed via the mailing list. While I have used the older version of *Klicker* with my students, I’m not yet proficient with the latest version.

Currently, one limitation of *Klicker* is that it doesn't seem to support direct interaction between users. However, here’s an example link to illustrate how it could work: [Jan’s opinion](https://pwa.klicker.uzh.ch/session/daf1a9ec-f26e-4ff4-ba79-30a8dd7b8cb6).

If anyone on the list knows of an alternative platform that might better suit this purpose, I’d appreciate recommendations and introductions to such tools.
