“…Processes simulated in WaSSI include infiltration, ET, surface runoff, snow accumulation and snow melt, soil water storage, and streamflow. Infiltration, soil storage, and surface runoff were computed with algorithms from the Sacramento Soil Moisture Accounting Model (Burnash, Ferral, & McGuire, ; Burnash, ) with input from the State Soil Geographic Database (STATSGO; Natural Resources Conservation Service, ) and 2005 domestic water usage data (USGS; Kenny & Juracek, ). A complete description of the WaSSI model can be found in Sun et al (, ) and Caldwell et al ().…”

Assessment of wildland fire impacts on watershed annual water yield: Analytical framework and case studies in the United States

et al. 2016

More than 50% of water supplies in the conterminous United States originate on forestland or rangeland and are potentially under increasing stress as a result of larger and more severe wildfires. Little is known, however, about the long-term impacts of fire on annual water yield and the role of climate variability within this context. We here propose a framework for evaluating wildland fire impacts on streamflow that combines double-mass analysis with new methods (change point analysis, climate elasticity modeling, and process-based modeling) to distinguish between multiyear fire and climate impacts. The framework captures a wide range of fire types, watersheds characteristics, and climate conditions using streamflow data, as opposed to other approaches requiring paired watersheds. The process is illustrated with three case studies. A watershed in Arizona experienced a +266% increase in annual water yield in the 5 years after a wildfire, where +219% was attributed to wildfire and +24% to precipitation trends. In contrast, a California watershed had a lower (−64%) post-fire net water yield, comprised of enhanced flow (+38%) attributed to wildfire offset (−102%) by lower precipitation in the post-fire period.Changes in streamflow within a watershed in South Carolina had no apparent link to periods of prescribed burning but matched a very wet winter and reports of storm damage. The presented framework is unique in its ability to detect and quantify fire or other disturbances, even if the date or nature of the disturbance event is uncertain, and regardless of precipitation trends.

“…As such, per capita residential water use of around 409 L per day is close to the national average despite the arid climate (Kenny & Juracek, 2012;Santos, 2013). Climate and its effect on evapotranspiration drive high levels of outdoor water use (Wentz & Gober, 2007), and much of domestic water use goes to support vegetation that would not be able to survive if reliant only on the 182 mm of rain that typically fall in a single year, given the average high temperature in July is 41.2 C (National Weather Service, 2015).…”

Detection of foreclosure-related landscape management changes using Landsat

et al. 2015

a b s t r a c tThe volume of properties affected by foreclosure over the past decade suggests the potential for dramatic change in vegetation cover due to changes in management. Yet, the specific pathology of each foreclosure, the temporal asynchrony among foreclosures, and differences in the area available for vegetation growth across properties presents challenges to observing and measuring change. This paper develops and tests a difference in deviations approach that compares the parcel NDVI to a neighborhood norm before and after foreclosure. The difference in deviations approach addresses the challenges of separating parcel-level change corresponding to foreclosure and identifies changes on both small and large parcels. The method relies on a time series of Landsat Normalized Difference Vegetation Index (NDVI) data, individual home foreclosure records and property tax assessment data for Maricopa County, Arizona from 2002 to 2012. To establish the level of difference associated with observable landscape change, we use a probit regression model, coding Google Earth images for properties across the range of observed deviations of difference. The basic assumption underlying the approach is that if foreclosure coincides with a change in management, it will lead to changes in vegetation structure and thus, NDVI values. We estimate that 13% of home foreclosures in Maricopa County over the period from 2002 to 2012 resulted in declines in vegetation whereas 6.5% resulted in vegetation increases. Future uses of this method for understanding landscape management in residential landscapes are discussed.

“…Kenny and others (2009) estimated that household water use is about 100 gal/d per person. However, some of that amount is used outdoors for watering lawns and gardens, washing cars, and other purposes (Barlow and others, 2009;Garrison and others, 2011;Kenny and Juracek, 2012). Most outdoor use occurs in the warm seasons, and in some areas the magnitudes of outdoor uses from year to year are correlated to precipitation (Barlow and others, 2009;Kenny and Juracek, 2012).…”
