Comparing Commonly Used Aquatic Habitat Modeling Methods For Native Fishes, Eryn K. Turney
Comparing Commonly Used Aquatic Habitat Modeling Methods For Native Fishes, Eryn K. Turney
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Water resources are managed for a variety of human needs, including agriculture, industrial and municipal consumption, hydropower generation, and recreation. There has been a recent push to incorporate habitat needs of aquatic wildlife into water management models alongside these other uses, particularly as competition for limited water resources in a changing climate has reduced instream flow and contributed to declining native fish populations. Habitat models are used to estimate species distributions and differentiate between suitable and unsuitable habitat based on variables important to a given species, but are not usually incorporated into water management models. Because there are many ways …
Big Fish And More Of Them: Salmonid Habitat Availability, Quality, And Use Across Multiple Scales Within A River-Reservoir System, John S. Mclaren V
Big Fish And More Of Them: Salmonid Habitat Availability, Quality, And Use Across Multiple Scales Within A River-Reservoir System, John S. Mclaren V
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Reservoirs and their associated rivers provide water for agricultural and municipal uses, ecological benefits for fish and wildlife, and associated recreational activity. However, in the Greater Yellowstone Ecosystem climate change and population growth are putting pressure on water quality and supply, potentially damaging the unique and economically important coldwater trout habitat that these systems support. In this study, the author investigates the impact of changing water quality and supply on trout habitat quality, quantity, and selection to assist conservation goals in the Henry’s Fork Watershed in eastern Idaho. The study found that higher availability of cold-water refuge habitat in Island …
Probabilistic Estimation Of Water Conservation Effectiveness, David E. Rosenberg
Probabilistic Estimation Of Water Conservation Effectiveness, David E. Rosenberg
Civil and Environmental Engineering Faculty Publications
An analytical method is derived to describe the distribution of water quantity saved among customers within a water-use sector who adopt a water conservation action. Analytical results tend toward lognormal distributions with long tails, quantifying a smaller subset of customers that show potential to achieve large savings. Example effectiveness distributions are shown for seven long-term conservation actions potentially implemented by urban, domestic water users in Amman, Jordan. Monte Carlo simulations verify the analytical derivations. The probabilistic outputs contrast with common methods that estimate conservation action effectiveness as a product of typical (average) characteristics for disaggregated customer groups. Implications to size …
