Changes in extreme climate event frequencies have markedly different effects on watershed nitrogen exports than do changes in mean temperature and precipitation
Aquatic reactive nitrogen threatens human health and riverine and coastal ecosystems, yet its behavior under climate extremes remains poorly understood. Here we use a frequently cited SPAtially Referenced Regression On Watershed attributes (SPARROW) model to systematically assess the influence of climate extreme frequencies, defined by type intensity, duration, seasonality and co-occurrence of precipitation and temperature events, on the delivery…
Temporal variability in irrigated land and climate influences on salinity loading across the Upper Colorado River Basin, 1986-2017
Freshwater salinization is a growing global concern impacting human and ecosystem needs with impacts to water availability for human and ecological uses. In the Upper Colorado River Basin (UCRB), dissolved solids in streams compound ongoing water supply challenges to further limit water availability and cause economic damages. Much effort has been dedicated to understanding dissolved solid sources, transport, and management in the region, yet tem…
Seasonally dynamic nutrient modeling quantifies storage lags and time-varying reactivity across large river basins
Nutrients that have gradually accumulated in soils, groundwaters, and river sediments in the United States over the past century can remobilize and increase current downstream loading, obscuring effects of conservation practices aimed at protecting water resources. Drivers of storage accumulation and release of nutrients are poorly understood at the spatial scale of basins to watersheds. Predicting water quality outcomes in large river basins dem…
Low threshold for nitrogen concentration saturation in headwaters increases regional and coastal delivery
River corridors store, convey, and process nutrients from terrestrial and upstream sources, regulating delivery from headwaters to estuaries. A consequence of chronic excess nitrogen loading, as supported by theory and field studies in specific watersheds, is saturation of the biogeochemically-mediated nitrogen removal processes that weakens the capacity of the river corridor to remove nitrogen. Regional nitrogen models typically assume that remo…
