Jacek Jaroszewicz developed user-facing documentation and visualization assets for two core algorithms in the Riverscapes-tools repository, focusing on hydrologic data analysis and algorithm visualization. He delivered comprehensive guides and figures for the Hydrologic Context Tool, detailing baseflow and flood discharge estimation using regression equation methodologies, and for the Confinement Algorithm, providing clear visual explanations of its logic. His work, primarily using Markdown for documentation, emphasized clarity and reproducibility, consolidating assets to streamline onboarding for new users. While the scope was limited to documentation and visualization, the depth of technical detail supported transparency and improved the usability of hydrology-focused analytical tools.
