Table of Contents:
- <div> <p><span lang="EN-US">This repository contains input data and analysis results used in the article titled:</span> <span lang="EN-US">"Two Decades of Nutrient Dynamics in Polish Rivers: Long-Term Trends in Nitrogen and Phosphorus". The dataset includes both <strong>raw monitoring data</strong> and <strong>processed outputs</strong> used in long-term trend analyses. Nutrient concentrations were combined with simulated daily <strong>river discharge data</strong>, and trends were evaluated using the <strong>WRTDS (Weighted Regressions on Time, Discharge, and Season)</strong> approach, implemented through the <strong>EGRET</strong> and <strong>EGRETci</strong> R packages. </span>The input data were collected from <strong>52 monitoring sites across Poland</strong> between <strong>2005 and 2022</strong> from the Polish Chief Inspectorate of Environmental Protection (<a href="https://wody.gios.gov.pl/pjwp/publication/367">GIOŚ</a>), <span lang="EN-US">operating within the framework of the State Environmental Monitoring Program</span>. The data include <strong>nitrate nitrogen (NO₃-N)</strong>, <strong>total nitrogen (TN)</strong>, and <strong>total phosphorus (TP)</strong> concentrations in flowing surface waters.</p> </div> <p>The dataset is saved in *.xlsx format and contains the following four tables:<br><strong>Legend</strong> – provides descriptions of column headings used in the other tables.<br><strong>waterQualityLocation</strong> – contains information (metadata) about the surface water monitoring sites,<br><strong>waterQualityData</strong> – summarizes the results of concentration and flow measurements (input data),<br><strong>EGRET_bootPairOut</strong> – presents the trend analysis results generated by the ECRETci model (output data).<br>Each table is included in a separate sheet in which the first line contains a table heading described by abbreviations without spaces.</p>
