Lately, I have been using Notepad++ as an R IDE. There are many reasons on why it might (or might not) be a good idea to abandon RStudio for a more lightweight option like Notepad++ for example. However, in this post I’m not gonna argue about which one is better, but rather I will show […]
RRIr: R scripts for the Rainfall-Runoff-Inundation model.
The last couple of months I have been following the newsletter and activities of ICHARM i.e., the International Centre for Hazard Assessment and Risk Management. ICHARM, situated in Japan, is one of the Water Centers under the auspices of UNESCO which conduct research on water-related disasters, among others. Below is a picture from their 2021 […]
A conceptual HBV hydrologic model written in R.
A while ago, I stumbled upon an interesting paper* where the authors presented a conceptual HBV hydrologic model. This model, which is basically a modification of the original HBV model developed by the Swedish Meteorological and Hydrological Institute (SMHI), takes as input the daily precipitation and temperature and turns this information in simulated streamflow. The […]
Modifying EVS source and adding the Ignorance Score.
The Ensemble Verification System (EVS) is an open-source java software tool for verifying ensemble forecasts of hydrometeorological variables. However, even though it comes with a variety of verification metrics to choose from, it lacks the Ignorance Score, a measure which I find one of the easiest to interpret and communicate to forecast users. The Ignorance […]
Open channel’s free surface.
A few years ago, as part of my BSc studies, I wrote a Fortran 90/95 program which defines the profile of free surface of water when flowing inside an open trapezoidal channel. Firstly, the program takes as input a few physical characteristics of the channel and calculates the critical and normal depth of the flow, […]
