Characterizing Hydrologic Conditions for Water Allocations<\/strong><\/p>\n\n\n\n

In-stream flow targets for environmental purposes are frequently tiered to real-time hydrologic conditions. However, characterizing those conditions to appropriately reflect hydrologic variability, especially in heavily-regulated river systems, can be a challenge. Don Anderson worked with stakeholders to develop criteria for the Platte River Recovery Program (USA) that set real-time flow targets determining when water regulation facilities associated with the species recovery effort can divert or store flows without conflicting with recovery efforts. This work is documented in Characterization of Hydrologic Conditions to Support Platte River Species Recovery Efforts<\/a>.<\/p>\n\n\n\n

Flow Forecasting Tool to Benefit Native Fish<\/strong><\/p>\n\n\n\n

In support of efforts by The Nature Conservancy and other Price River, Utah, basin interests, Cresta Hydrologics developed this tool<\/a> to aid water managers in determining, by April 1 of each year, whether basin hydrologic conditions were likely to result in either (a) unusually low flows in the lower Price River in the June-September period or (b) peak flows in the April-June period that could approach bankfull conditions — either case presenting specific opportunities to benefit native fish with augmented instream flows.<\/p>\n\n\n\n

Road Network Erosion Modeling to Protect Marine Resources<\/strong> <\/p>\n\n\n\n

Working with the U.S. National Park Service, Don Anderson conducted watershed-scale studies of long-term and present-day erosion and sediment delivery on St. John, U.S. Virgin Islands. He established the first quantitative estimates of erosion and sediment delivery associated with specific land use activities on the island<\/a>, and developed recommendation for sediment control practices to protect sensitive marine resources, using GIS-based models of surface hydrology, slope stability, and soil erosion. Study results were published as a 153-page Park Service technical publication.<\/p>\n\n\n\n

Flow Recommendations<\/strong> for a Colorado River Tributary<\/strong><\/p>\n\n\n\n

Working with partners of the Upper Colorado River Recovery Program, and based on a review of 25+ years of biologic, hydrologic, and fluvial geomorphologic data, Don Anderson and co-authors developed interim flow recommendations<\/a> for federally listed endangered fish associated with the White River in western Colorado and eastern Utah. These recommendations established the basis for subsequent fish protection and recovery strategies being incorporated into a White River endangered fish management plan.<\/p>\n","protected":false},"excerpt":{"rendered":"
