Project objectives
Project objectives decision-support tool to assess water availability at ungaged stream locations in Massachusetts

  • Develop an easy-to-use, screening-level, decision-support tool to estimate continuous unregulated and regulated daily streamflow at ungaged locations in Massachusetts

POINT-AND-CLICK GIS USER-INTERFACE COUPLED WITH COMMONLY-USED SPREADSHEET AND DATABASE SOFTWARE

USER CAN TEST WATER-MANAGEMENT SCENARIOS BY ADJUSTING THE PERIOD OF ANALYSIS AND CHANGING INPUT DATA

TECHNICALLY-DEFENSIBLE APPROACH REQUIRING FEW PARAMETERS

Selection of an index gage using geostatistics
Selection of an index gage using geostatistics decision-support tool to assess water availability at ungaged stream locations in Massachusetts

Each point on the map is the Pearson’s r correlation between the natural logarithms of the streamflows at BURL and another gage.

EXAMPLE

By kriging the correlations, we obtain a correlation map for southern New England, which can be used to determine the correlation between any stream location and the BURL gage.

R2 = 0.839

Selection of an index streamflow gage continued

We can create a correlation map for each of the potential index gages in our study area.

Now suppose we want to select the gage most correlated with our ungaged site.

We can obtain kriged estimates of correlation between our ungaged site and each of the index-streamflow gages in the study area.

Estimated R2 between ungaged site and the BURL gage = 0.845

Estimated R2 between ungaged site and the OLDS gage = 0.793

Estimated R2 between ungaged site and the GREC gage = 0.882

R2 = 0.882

R2 = 0.845

R2 = 0.793

We will use the GREC gage to transform the flow-duration curve to a time series of flows.


Streamflow gages used in the analysis decision-support tool to assess water availability at ungaged stream locations in Massachusetts

There are 66 gages identified as least-altered in southern New England.

Most sites have no major water withdrawals, discharges or return flows in the basin and the predominant land cover is forest.

The MA SYE tool estimates daily mean streamflows from October 1, 1960 through September 30, 2004.

Each site was jack-knifed to compare estimated and observed streamflows.

  • If aquifer properties are known, the user has the option to apply the program STRMDEPL, an analytical solution that is used to include the time-varying effects of a ground-water withdrawal or discharge on streamflow

Limitations
Limitations decision-support tool to assess water availability at ungaged stream locations in Massachusetts

  • Regulated streamflow estimates are limited by the availability and quality of the water-use data

  • Estimates of regulated streamflow do not include other factors that have an effect on streamflow: land-use change, surface-water reservoirs, storm-water returns, and septic discharge

  • Method requires coincident ground- and surface-water divides

    • Existing ground-water-flow models are used to compute streamflow at fixed stream locations where divides are not coincident

Point and click gis user interface
Point-and-click GIS user-interface decision-support tool to assess water availability at ungaged stream locations in Massachusetts

Users also have the option to export a map and shapefile of the study area.

Users begin by opening an ESRI ArcMap document and locating the stream of interest.

The user clicks on the stream location to delineate an on-the-fly watershed, compute basin characteristics, and query the water-use database for points within the watershed.


Navigating the tool decision-support tool to assess water availability at ungaged stream locations in Massachusetts

All relevant data is stored in a user-specified location and project folder.

A master Microsoft Excel file guides the user through the post-processing, graphing and reporting of the results.
