Data Analysis Tools

The Alkalinity Calculator will analyze the titration curve and calculate the alkalinity or acid neutralizing capacity (ANC) of the sample using one or more of several different methods. Alkalinity is for filtered samples, while ANC is for unfiltered samples. The results will be displayed in tabular and graphical form.

A map app to get recharge values from streamgage locations in Pennsylvania. Development of this app is described at the Related Science page.

An easy-to-use, Web-based geodatabase of historical flood and paleoflood information which includes links to sources of flood data. The interface makes this collection of information useful to water-resource managers to better understand the historic events for improved flood-frequency estimates of the largest floods in Colorado.
