ABSTRACT:

This data set includes data for the Functional Flow Reference Hydrographs for 43 Gage Stations across the Rio Grande/Rio Bravo Basin under the Natural and Regulated Flow Regime and for 16 gage stations under the Resilient Flow Regime. The concept of the resilient flow regime is a flow regime that absorbs some perturbation by human alterations but still preserves ecologically beneficial characteristics associated with the natural flow regime. The resilient flow regime is derived from the period when there was human alteration, but the flow characteristics remained within the variability of the natural flow. The resilient period is identified using resilience theory by calculating time thresholds, which refer to a point in time (e.g., a year) when a permanent flow regime shift occurred. The Functional Flow Metrics were calculated for the daily naturalized and regulated streamflow data for 43 gage stations using the functional flow calculator. A series of FFMs were obtained for each year on record, and each metric is used to construct the Functional Flow Hydrographs that represent the natural, regulated, and resilient flow regime.
