ABSTRACT:

For my final project, I wanted to look at how the concentration of nitrogen and phosphorus in the Sacrament River changed after both the 1999 Jones fire and the 2013 Clover fire hit Whiskeytown National Recreation Area. To do this, I found relevant CUAHSI data and analyzed it using python. I then published my findings as a HydroShare resource. The 1999 Jones Fire and the 2013 Clover Fire were both significant wildfires that occurred in California, each leaving a lasting impact on water quality in the region. The Jones Fire, which ignited in Nevada County, burned over 27,000 acres of land, predominantly in the Tahoe National Forest. Similarly, the Clover Fire, originating in Shasta County, scorched approximately 8,000 acres of land. Both fires generated substantial amounts of ash, sediment, and debris, which washed into nearby waterways during rainfall events, compromising the water quality of tributaries and rivers such as the Sacramento River. The influx of pollutants posed risks to aquatic habitats and downstream communities reliant on clean water sources. These events underscore the broader challenge of managing wildfires and their aftermath to mitigate environmental degradation and safeguard water resources for both human and ecological needs.

ABSTRACT:

Irrigation of residential properties in urban settings is typified by small and irregular areas, many untrained water users, limited end-use metering, and differing groundcover in contrast to agricultural settings. This makes analyzing irrigation patterns to promote efficient water use challenging. Analysis of Irrigation by Remote Sensing (AIRS) combines multispectral aerial imagery, evapotranspiration data, and ground-truthed measurements to overcome these challenges. We demonstrate the application of AIRS on eight neighborhoods in West Haven, Utah using 0.6 m National Agriculture Imagery Program (NAIP) and 0.07 m drone imagery, reference ET, and water meter data from Weber Basin Water Conservancy District (WBWCD). We find the difference between the actual and hypothetical water required for each parcel and compare water use over three time periods of interest (2018, 2021 and 2023). We find that users are overwatering by smaller amounts with time. Using AIRS would allow water utilities to track water user habits over time and see if conservation efforts impact water usage. I included a a shapefile showing where secondary meters are placed, where Utah counties are, as well as a Landsat image.
