Mostly in Python, with some Go on the side.</p> <p>Find me on <a href="https://github.com/rhkarls">GitHub</a> to see what I am working on.</p>https://rhkarls.github.io/page/cv/Fri, 10 Apr 2026 00:00:00 +0000https://rhkarls.github.io/page/cv/<h2 id="experience">Experience</h2> <h2 id="add-your-work-experience-here"><em>Add your work experience here.</em></h2> <h2 id="education">Education</h2> <h2 id="add-your-education-here"><em>Add your education here.</em></h2> <h2 id="skills">Skills</h2> <h2 id="add-your-skills-here"><em>Add your skills here.</em></h2> <h2 id="publications">Publications</h2> <p><em>Add any publications or reports here.</em></p>https://rhkarls.github.io/page/projects/Fri, 10 Apr 2026 00:00:00 +0000https://rhkarls.github.io/page/projects/<h1 id="code-projects-currently-on-github">Code projects currently on GitHub</h1> <h2 id="eplines">eplines</h2> <p><a href="https://github.com/rhkarls/eplines">eplines repository</a> | <a href="https://pypi.org/project/eplines/">eplines on PyPI</a></p> <p>A small visualization package producing empirical and exceedance probability/frequency heatmaps and cycle plots of many or long time-series.</p> <p>Can for example be used to visualize exceedance frequency at different times of the year for streamflow time series — basically a flow-duration curve for each day of the year:</p> <p><img src="https://rhkarls.github.io/img/discharge_exceedance_example.png" alt="fdc_eplines"></p> <p>The above graph shows the cumulative frequency of streamflow for each day of the year: how often specified discharges were equaled or exceeded. Low flows are exceeded often (values close to 1, with 1 meaning exceeded 100% of the time). Extreme high flows occur less often and have lower exceedance frequency.</p>
