Data for Investigating the Joint Effect of Changes in Impervious Cover and Climate on Trends in Floods

This data release contains data in support of "The Joint Effect of Changes in Impervious Cover and Climate on Trends in Floods: A Comparison of Panel and Single-Station Quantile Regression Approaches" (Over and others, 2025). It contains input and output data used to analyze the effect of impervious cover and climate changes on trends in floods using three regression approaches. The input consists of two files: "finalStationList.csv," which contains streamgage information for the 127 streamgages used in this study, and "regressionInput.csv," which contains data used as input into regressions for each streamgage. The output consists of "lm_trends.csv," "byStation-log10_ann_max_MWBM_Q.csv," and "FixedEffects-log10_ann_max_MWBM_Q.csv." "lm_trends.csv" contains trend analysis results by streamgage. "byStation-log10_ann_max_MWBM_Q.csv" contains the regression results for annual maximum streamflow from MWBM and impervious fraction by streamgage. "FixedEffects-log10_ann_max_MWBM_Q.csv" contains fixed effects for annual maximum streamflow from MWBM and impervious fraction by streamgage.

Also included is "modelArchive.zip", which contains the scripts used to create the data provided in this data release and in Over and others, 2025. It contains the input data necessary to run the scripts and readMe files with directions for running the scripts locally.
