RS MINERVE has increased its visibility since its creation in 2011. Over 2015, we have had visits from 56 different countries. Main visitors come from Switzerland, Peru, Spain, Brazil, Mexico, the United States, Canada and South Korea.

During the first 7 months of 2015, we have had more than 3’000 pages viewed by more than 1’000 visitors accounting for more than 300 downloads of RS MINERVE. If we add direct downloads from the officiel download page on the Crealp website, more than 700 people have already downloaded RS MINERVE this year !! We are becoming a big community and we thank all the users for being part of this adventure !


Operational forecast newly based on RSMINERVE 2.0

Since July 2015, the CREALP (Centre de recherche sur l’environnement alpin) provides hydrological forecasts based on the new software version RS MINERVE 2.0.  The forecast results are used as a basis for flood prediction and flood emergency response planning for the Canton of Valais.

Three times a day, the operational system performs real-time forecasts using RS MINERVE 2.0 with command-line scripts.  Two simulation tasks are run at each time:

  • The first task, called ‘Control simulation’ simulates the last 24 hours, based on observed meteorological and measured river discharges. This task serves as control and variable initialization for the second task.
  • The second task is the ‘Forecast simulation’ which provides predicted flows for the Rhone and its tributaries, using the COSMO-7 meteorological forecast from MeteoSwiss.

Called from a DOS Terminal, each task is composed of a VBScript containing all the functions required to perform a hydrological simulation, such as launching RS MINERVE, opening the model, loading the inputs, performing the simulation and saving the results.

Documentation about the use of command-line scripts will be available with the official release of RSMinerve 2.0 in Fall 2015.


Why you should try RS MINERVE !

Have you ever used RS MINERVE ? Not yet ? Do you know its advantages compared to other similar programs? Some reasons why RS MINERVE could be really interesting for you are given hereafter :

  • The hydrological-hydraulic model can be built with different hierarchical levels (called sub-models) which easily allow the organization of your model per region. A must for large models!
  • The different hydrological models (SOCONT, HBV, SAC-SMA, etc) can be easily converted from one to another in order to test which model provides the best performance.
  • The RS GIS tool allows the connection between the hydrological model and the shapefiles. The simulation and visualization of the results can then be directly realized from the RS GIS.
  • The user-friendly interface has been built for an easy understanding of the program and you can rapidly execute you first hydrological simulation.
  • The calibration module performs perfectly optimization of the hydrological parameters. Different algorithms can be tested and the objective function can be  modified to adapt it to the user’s interest.
  • You do not need to create meteorological series for each element of your model, but only a database with your observed meteorological data. Then,  each element will automatically build its meteorological series based on the database.

Soon joining the RS MINERVE community ?


Model simulation and visualization from RS GIS

Did you know that you can simulate directly from RS GIS in RS MINERVE?  Did you know that you can even view results also from RS GIS?

Once a simulation is achieved, RS GIS allows the visualization of series (hydrographs, reservoir levels,…) directly from the shapefiles when they are linked to the hydrological model.

You can click on basins, rivers or junctions from different shapefiles to visualize every result produced by RS MINERVE.

In addition, you can also visualize 2D results for a selected date to spatially represent the model’s results such as snow cover or soil saturation. Visualizing model properties, initial conditions and variables could not be easier !

Don’t hesitate to test new functionalities which become a key to represent results in a simple and a performant way in order to understand model outcomes.

Courses about ‘Hydrological and hydraulic modelling with RS MINERVE’ in Lima (Peru) – April 2015

Two courses (beginner and advanced) about ‘Hydrological and hydraulic modelling with RS MINERVE’ have been held on April 13th to 15th and on April 16th and 17th 2015 in the Headquarters of the National Service of Meteorology and Hydrology of Peru (SENAMHI), in Lima, Peru.

In the first course, for beginners, theoretical and practical parts have been combined to provide the required knowledge to model hydrological basins with the help of RS MINERVE. 35 participants from different Peruvian organizations and consulting enterprises have taken part with a great interest and success.

In the second course, for advanced users which already followed the course for beginners in 2014 or 2015, the details of the RS GIS and the RS Expert modules where revealed. Then, a practical exercise allowed the participants to become experts in hydrological and hydraulic modelling with RS MINERVE. About 25 participants took part in this course, with a big success that predicts another time two courses for 2016.

The courses, taught by J. García Hernández and J. Fluixá Sanmartín, from the Centre de recherche sur l’environnement alpin (CREALP-Switzerland) and by J. Paredes Arquiola, from Technical University of Valence (UPV-Spain), was organized in collaboration with the SENAMHI, the CREALP, the University of Zurich, the Swiss Agency for Development and Cooperation (SDC), Meteodat, Care Perú, ProyectoGlaciares and the Ecole Polytechnique Fédédale de Lausanne (EPFL).

New algorithms for hydrological parameters optimization

In addition to the SCE-UA (Shuffled Complex Evolution – University of Arizona), used for the optimization of the hydrological parameters in RS MINERVE, two new algorithms have been implemented: the “Uniform Adaptive Monte Carlo” and the “Coupled Latin Hypercube and Rosenbrock”

The Uniform Adaptive Monte Carlo (UAMC) algorithm is based on the Monte Carlo experiments that rely on repeated random sampling but has been modified in order to iteratively adjust the solution space.
The algorithm randomly launches a collection of simulations (block) and finds the better results in the solution space. Afterwards, the solution space is adjusted and a new group of simulations starts. The process is repeated until the optimization converges to the best set of parameters.

The Coupled Latin Hypercube and the Rosenbrock algorithm, generates a powerful tool for optimization of complex problems. This combined algorithm can discretize a wide domain and then narrow your search to smaller sectors. Scanning of the space of possible solutions is performed by the Latin Hypercube. This algorithm allows pseudo-statistical sampling conditioned by the previous calculated solutions. The Latin hypercube is an evolution of the Monte Carlo method, with more homogeneous samples achieved with fewer samples. An important advantage of this method is that the dimension of the problem is defined by the division of the latin hypercube and not by the number of parameters.
The best results from samples become the starting points required for Rosenbrock algorithm. The advantage of this subroutine calculation lies in the speed to obtain near optimal values. This algorithm is based on a gradient search, adjusting axis changes based on the direction of maximum enhancement, thus reducing the number of evaluations of the objective function.

The course, taught by Javier García Hernández, Alain Foehn, Samuel Alesina and Javier Fluixá Sanmartín, from the Centre de recherche sur l’environnement alpin (CREALP) and some members of the Steering committee of Hydro10, was organized by the CREALP in collaboration with the Ecole Polytechnique Fédérale de Lausanne (EPFL), the Technical University of Valencia (Spain) and the Hydro10 Association.

Vectorial icons for hydrological-hydraulic objects

Hydro10 collaborates in the development of RS MINERVE and has created a new graphic line with vectorial images for all available objects  in RS MINERVE.

The attractiveness of a software comes not only from a robust mathematical basis but also from an enjoyable interface. The new icons will improve the quality of the user-friendly graphical interface and the details when zooming. This new development reinforces the look of the software and enhances the significant work achieved about new modules  in recent months.
