ABSTRACT:

Hydropeaking is a phenomenon that causes daily variation in flow from hydropower dams. The hydropeaking at the Glen Canyon Dam has high range (difference of daily and and low) and has caused lowest diversity of the EPT population downstream the dam. We present a range of flows and corresponding volumes for different scenarios of discharge from the dam that are suitable to provide conditions to sustain the hydropeaking and increase the bug population.

Project Abstract:
Human-caused climate change poses a threat to the ski industry and communities that rely on ski tourism. However, resorts may be able to mitigate some of the social and economic impacts using adaptation strategies. We analyze historical weather data, future climate projections and interviews with Utah ski resort managers to investigate the effects of climate change for ski resorts across the state of Utah (USA). We investigated past trends at all Utah resorts from 1981 – 2018, and future projections for Utah from 2020 – 2100 under two different climate change scenarios (Representative Concentration Pathway (RCP) 2.6 and RCP 8.5). We also conducted semi-structured qualitative interviews with Utah resort mangers to understand how they perceive climate change impacts, adaptation strategies, and barriers to adaptation. We found that resorts in Utah are warming faster than global averages, with an increase in mean maximum temperatures by 1.5°C - 2.6°C from 1981 - 2018 during the ski season. By the end of the century, Utah could warm an additional 5.7°C under RCP 8.5. Resort managers are concerned about shorter season lengths, shifting ski seasons, less snow cover, and less quality snow. Resorts are already adapting by using snowmaking and diversifying offerings. However, barriers to adaption include financial costs plus low temperatures and adequate water availability for snowmaking. Climate change is already impacting resorts, but adaptation practices are likely to reduce the negative impacts at most of the the Utah ski resorts from a warming climate.

ABSTRACT:

The Colorado River Compact apportions water between upper and lower basin and requires the upper basin to deliver a total of 7.5 MAF to lower basin each year. The Colorado river system has been very reliable in past and has survived many dry periods without failing to meet the demand requirements of both basins. The drought that began in the region at the turn of the century has rendered it very difficult for the upper basin to meet the delivery requirements to the lower basin. Many management options have been explored and some have been implemented to maintain increase the reliability of the system. This report focuses on creating a pareto front for the reliability of the Colorado river supply in response to demands to upper and lower basin. This could help in identify what would be the tradeoffs for reliability of one basin if the system is managed to meet the requirements of the other basin.
