This is the summary of what Francesco Serafin did in its first year of doctoral studies, defending for his admission to his second year Ph.D. Undoubtedly he did a lot of work and he program to di even more. Three are the lines of his research: implementing a new flexible structure based on graphs for commanding simulations of interacting systems; implementing a domain specific language for doing environmental models (and particularly to solve ordinary and partial differential equations); deplying a system that makes easier to do replicable science.
The document discusses various geomorphological analysis tools available in the open-source software HortonMachine. It describes how HortonMachine can be used to analyze digital elevation models (DEMs), calculate terrain attributes, extract stream networks, and delineate catchment boundaries. Specific commands are mentioned for calculating flow directions, drainage networks, slope, curvature, catchment attributes and more. The goal is to provide quantitative and qualitative tools for understanding catchment morphology.
Parma 2016-05-17 - JGrass-NewAGE - Some About The State of ArtRiccardo Rigon
This describes the motivation behind the JGrass-NewAGE infrastructure. It also shows the main components that were implemented. Finally it shows and comments some case studies and some use cases
This document summarizes the history and future of JGrass, an open source Java GIS application that provides a graphical user interface and plugins for the GRASS GIS. It describes the motivation for JGrass 1.0 and 2.0, challenges faced, and the decision in 2007 to join with the uDig community. Key points covered include improved support for shapefiles, DWG files, and the GRASS raster library in JGrass 3.0 through integration with uDig and its plugins.
Return period from a stochastic point of viewRiccardo Rigon
Volpi and coworkers discussed the idea of return period. Her statement is that independence is not a requirement for obtaining the classical equation of return period.
This is inscribed in the old story of stochastic processes used as representation of phenomena that appear highly variable. The field needs some refreshment after the discovery of climate change. Volpi's et al. Has the merit to bring in some novelty. I was intrigued by the separation and relation between return period and waiting time.
The document discusses the use of different hydrological models. It notes that while every hydrologist would like a single model, different problems require different levels of detail. As such, various models are used, including GEOtop for fully distributed, grid-based modeling; NewAge for large-scale hillslope-stream modeling and anthropic infrastructures; Boussinesq for fully coupled subsurface-surface modeling; and PeakFlow for GIUH and peak flood modeling. The models each have their own appropriate applications and levels of detail.
GEOtop 2.0 - The snow and freezing soil modellingRiccardo Rigon
This is the second talk given at AGU Fall Meeting 2013. It complements the first talk by presenting something of the new snow modelling, and freezing soil algorithms
This document describes a graphical language for representing reservoir systems using time-continuous Petri nets (TCPN).
Places in the TCPN represent water storages such as volumes of groundwater or energy/momentum contents. Transitions represent fluxes between storages. The TCPN uses colors to distinguish different types of quantities (mass, energy, etc.) and storages. Connections between places and transitions represent differential equations governing the system.
An example TCPN represents a system of three differential equations with three storages, inputs, and both linear and nonlinear fluxes. Additional information like parameter values can be provided in tables. Adjacency matrixes describe the connections between places and transitions. TCPNs provide an algebraic framework for conceptual
Young and old forest impacts on the hydrological cycleRiccardo Rigon
Manoli uses a simplified ABL theory to study the effects of vegetation on precipitations, and, in particular he sorted out the effects of vegetation ages. Some about the theory of ABL came from the good old John Albertson work but the novelty here is that eco-hydrology enters in the merit of phenology-plants evolution. Conditions in which conclusions are drawn are pretty uniform (probably Durham forest can be considered a nice approximation of it), and this call for a treatment made with a process-based model
Abstract. This talk is about the GEOtop and JGrass-NewAge model, their physical bases, their informatics based on older (the first) and new (the latter) programming paradigms, the lessons I learned in building them with my group of people in an academic environment, their future, and the understanding that there is no the best model, but certainly a better way to do models.
Hydrological modelling was for long time, and still is, almost a synonym of simulating rainfall-runoff. Recently, however, the scope of hydrology became wider, even among engineers. Modelling in hydrology now certainly still means modelling discharges, but also modelling snow, evapotranspiration and turbulent exchanges, and surface/subsurface interactions. With the goal of reproducing the whole picture of the terrestrial hydrological fluxes, my coworkers and I worked together in the last decade to build new models and new types of models. We started from the lesson by P. Eagleson, and we built first the process-based (grid based) GEOtop model. GEOtop is “terrain-based” (it is based on the use of digital terrain models and uses the knowledge of interaction between morphology and process) “distributed” (all the simulated variables are calculated for each pixel of the basin) model of “the water cycle” (it simulates all the components of the water cycle, accounting for both the mass budget and the energy budget, the two budget equations being coupled through the temperature of the soil, which controls evaporation, hydraulic conductivity, and accumulation of the snowpack). However, this GEOtop was intimidating many, either for the complexity of the process and its internals, and possibly not adapted to large scale modelling where faster solutions are required.
Therefore we also worked on a different, more parsimonious model, called JGrass-NewAGE. From the lesson learned by implementing and maintaining GEOtop, we also found necessary to build the new model on new informatics. This system sacrifices process details in favour of efficient calculations. It is made of components apt at returning statistical hydrological quantities, opportunely averaged in time and space. One of the goals of this implementation effort was to create the basis for a physico-statistical hydrology in which the hydrological spatially distributed dynamics are reduced into low dimensional components, when necessary surrogating the internal heterogeneities with "suitable noise" and a probabilistic description. Unlike other efforts of synthesis, JGrass-NewAge keeps the spatial description explicit, at various degrees of simplicity. This has been made possible by opportune processing of distributed information which, in this way, has become part of the model itself.
Metastatistical Extreme Value distributionsRiccardo Rigon
- The document presents the Metastatistical Extreme Value (MEV) distribution as an improvement over classical extreme value theory.
- MEV accounts for the stochasticity in both the number of rainfall events per year and the parameters of the underlying rainfall distribution. This better represents scenarios with limited data where the asymptotic assumptions of classical methods break down.
- The author applies MEV using a Weibull distribution for daily rainfall and finds it outperforms generalized extreme value and peak over threshold methods by reducing estimation errors of rainfall quantiles by around 50% on average across diverse datasets.
This describes the research efforts made on the river Adige in CLIMAWARE and GLOBAQUA projects by the Hydrology group of University of Trento. This is the Italian version.
Reservoirology#4 or the representation of PDEs with TC Petri netsRiccardo Rigon
This document presents a graphical method for representing systems of partial differential equations using Petri nets. It uses the 1D Richards equation modeling unsaturated flow as an example. Key aspects covered include representing the state variable, fluxes, boundary conditions, ancillary expressions, and coupling between surface and subsurface domains. The method allows for a complete representation of complex partial differential equation systems through graphical notation.

Virtual water refers to the water used in the production of agricultural and industrial products. Large amounts of water are required to produce many goods - for example, 1kg of beef requires 16,000kg of water. Countries import virtual water when they import water-intensive goods produced elsewhere. This is important for water-stressed countries. For example, in Southern Africa the average annual runoff in South Africa is 45.2km3/year, while Lesotho contributes an additional 5.2km3/year through water transfers. Several countries in the region are already experiencing water stress according to common definitions. The document provides statistics on water availability and usage in several Southern African countries.
John Dalton established quantitative hydrology in 1799 by creating a water balance for England and Wales using rainfall and river flow data. He attributed the origin of springs to rainfall, rejecting long-held myths and laying the foundation for the modern understanding of the hydrological cycle. Recent work has focused on understanding soil evaporation dynamics at the pore scale, finding that as the soil surface dries, the spacing between pores increases, leading to higher evaporative flux per pore that can maintain an overall constant evaporation rate despite a decreasing surface area. This pore-scale model provides insights into evaporation rates, surface resistance, and energy partitioning during drying.

The title describes it all. Jeremy Pal's student Brianna Pagàn and coworkers put an impressive set of tools to estimate the impacts of land use and climate change on water resources of south California.
The document discusses modern approaches to flood forecasting. It begins by noting the importance of data collection and organization for hydrological modeling and forecasting. Key tools mentioned for hydrological modeling include HEC-HMS, SWAT, and SWMM. The document also discusses the importance of using multiple linked models to account for hydrological and hydraulic processes. Examples provided include systems used by ARPAE in Italy and the state of Iowa in the US. These contemporary approaches are characterized as using high-resolution data, multi-objective multi-process models, and cyberinfrastructure to run complex distributed hydrological models. However, the document notes that while such sophisticated systems provide valuable information, there are still open questions around verification at small scales

S [L3

T°1
], ET [L3

[L3

] are precipitation, evapotranspiration, and runoff (surface and groundwater)
respectively. The Qis represent input fluxes, of the same nature of Q, coming from
adjacent control volumes.

It is clear that Eq.(5.1) is governed by two types of terms, which can be easily identi-
fied as “inputs" and “outputs". The outputs are certainly evapotranspiration, ET, and
discharges, Q, including the Qis, because they come from the assembly of control volumes.
The inputs are J(t), but this term has to be split into rainfall and snowfall. Moreover,
other inputs are ancillary to the estimation of outputs, in particular temperature, T and
radiation Rn. Another input of the equation is the definition of the domain of integration
and its“granularity", i.e. its partition into elements for which a singe value of the state
variables is produced.
In this paper we discuss the estimation of all of these input quantities, with the

basin outlet, but in this application we excluded it because at these scales (of around ten
kilometers) travel time in channels is irrelevant (D’Odorico and Rigon, 2003). Eventually
the Hymod component provides an estimate of the discharge at each link of the river
network of the watershed, downstream to the HRUs.

Several validation studies of SREs have been conducted in the Ethiopian UBN basin
(Dinku et al., 2007, 2008; Haile et al., 2013; Gebremichael et al., 2014; Worqlul et al.,
2014; Romilly and Gebremichael, 2011; Hirpa et al., 2010; Habib et al., 2012). For

We divide the UBN basin into 402 subbasins and channel links as shown in figure 7.2.
This spatial partitioning may not be the finest scale possible, however, considering the
size of the basin, it can be considered an acceptable compromise to capture the water
budget spatial variability.
