Decision Support Systems Completed
It is a difficult task to determine the desirable environmental targets for aquatic resource managers, because of a myriad of physical, hydrological, and biological processes affecting aquatic ecosystems and hydroscapes, the complexity of interactions and the multifaceted information, and substantial levels of uncertainty. Computer-based Decision Support Systems (DSS) can help integrate and communicate scientific information and analyses, and thus provide support tools for decisionmaking. The AS Branch is working on DSS development to generate spatially explicit indices of habitat suitability for various flow scenarios.
DSS integrates spatially explicit environmental data, alternative water flow scenarios, flow-specific hydrodynamic estimates of local habitats, estimates of physical-chemical conditions, and habitat suitability criteria for key taxa. Our work creates and improves geospatial integration and representation of flow-dependent habitat suitability and the scoring systems for alternative flow regimes, based on continually improving flow data and statistics and quantitative understanding of site-specific relations between flow and desired environmental conditions.

Small Unoccupied Aircraft System (sUAS) Flights
Small Unmanned Aircraft Systems (sUAS) are an emerging technology which may result in safer and improved methods to conduct wildlife surveys. The objective of this task is to test the capabilities of various cameras and sensors onboard a small Unoccupied (or unmanned) Aircraft System (sUAS) to determine if they are a useful and effective tool to inventory various flora and fauna important to USGS... - Publications

Development of a decision support tool for water and resource management using biotic, abiotic, and hydrological assessments of Topock Marsh, Arizona
Topock Marsh is a large wetland adjacent to the Colorado River and the main feature of Havasu National Wildlife Refuge (Havasu NWR) in southern Arizona. In 2010, the U.S. Fish and Wildlife Service (FWS) and Bureau of Reclamation began a project to improve water management capabilities at Topock Marsh and protect habitats and species. Initial construction required a drawdown, which caused below-aveAuthorsChristopher Holmquist-Johnson, Leanne Hanson, Joan Daniels, Colin Talbert, Jeanette HaegeleAn integrated Riverine Environmental Flow Decision Support System (REFDSS) to evaluate the ecological effects of alternative flow scenarios on river ecosystems
In regulated rivers, managers must evaluate competing flow release scenarios that attempt to balance both human and natural needs. Meeting these natural flow needs is complex due to the myriad of interacting physical and hydrological factors that affect ecosystems. Tools that synthesize the voluminous scientific data and models on these factors will facilitate management of these systems. Here, weAuthorsKelly O. Maloney, Colin B. Talbert, Jeffrey C.
