Stable isotopes of oxygen and hydrogen in the Truckee River–Pyramid Lake Surface‐Water System. 2. A predictive model of δ18O and 182H in Pyramid Lake
Limnology and Oceanography, 1994Co-Authors: Steven W Hostetler, Larry BensonAbstract:A physically based model of variations in WO and 6*H in Pyramid Lake is presented. For inputs, the model uses measurements of liquid Water inflows and outflows and their associated isotopic compositions and a set of meteorological data (radiative fluxes, air temperature, relative humidity, and windspced). The model simulates change of lake volume, thermal and isotopic stratification, evaporation, and the isotopic composition of evaporation. A validation of the model for 1987-1989 and 199 1 indicates that it can reproduce measured intra- and interannual variations of 6’*0 and 6*H. Three applications of the model demonstrate its ability to simulate longer term responses of VO to change in the hydrologic balance and hydrologic characteristics (opening and closing) of the lake. Annual variations of the isotopic (al80 and a2H) composition of Pyramid Lake are associated by Benson (1994) with annual patterns of precipitation, evaporation, streamflow discharge, and lake mixing (stratification). Larger, long-term changes in isotopic composition are linked to change in the hydrologic balance and the hydrologic state (e.g. whether the lake is open or closed) of the lake. In this paper, we present a model used to simulate variations in 6180 and 62H in Pyramid Lake that occur in response to change in the hydrologic balance and climate. Several steady state and dynamic models of al80 and 62H have been developed and applied

Stable isotopes of oxygen and hydrogen in the Truckee River‐Pyramid Lake Surface‐Water System. 3. Source of Water vapor overlying Pyramid Lake
Limnology and Oceanography, 1994Co-Authors: Larry Benson, James W C WhiteAbstract:During 1988 and 1989, a series of Water-vapor extractions were conducted in the Pyramid Lake basin to determine the source of moisture that overlies the lake. Calculations of the isotopic and Water-vapor balances were made from isotopic and meteorological data from the Pyramid Lake and Reno, Nevada, areas. The results indicate that in the warm season, most of the moisture that overlies the lake is derived from evaporation as opposed to advected moisture. Isotopic fluxes at the lake Surface can be approximated by climatic data from the lake site, which simplifies the calculation of this input in numerical simulations of the isotopic evolution of the lake. The stable-isotopic composition of a lake is a function of the volume-weighted isotopic values of each component of the lake’s hydrologic balance. Researchers have used the stable-isotope history of a lake together with the volume-weighted isotopic composition of easily measured components of the hydrologic balance to estimate the stable-isotope values or amounts of less easily measured components of the hydrologic balance (see IAEA 1970, 1979). It is usually relatively simple to quantify the amounts and isotopic compositions of components of the Surface-Water System and the isotopic composition of groundWater. It is often more difficult to quantify the amount and direction of groundWater transport across the sediment-Water interface and the amount and isotopic composition of lake Surface evaporation. The isotopic value of Water evaporated from a lake is highly dependent on the isotopic value Acknowledgments We express our appreciation to those who assisted in sampling, including Jim Davis, Dan Mosley, and Nancy Vucinich. Special thanks to Irving Friedman, who loaned us the copper traps used for Water-vapor extraction; to Carol Kendall and Tyler Coplen, who oversaw the isotopic analyses; to James Ashby, who maintained the weather stations; and to Steve Hostetler, who extracted the meteorological data from the weather-station database and stratified the wind data for the Sutcliffc and Northshore sites. We also thank Zell Peterman, Steve Hostetler, and Pieter Tans for reviews of earlier versions of this manuscript.

Natural and NH4+-enriched zeolitite amendment effects on nitrate leaching from a reclaimed agricultural soil (Ferrara Province, Italy)
Nutrient Cycling in Agroecosystems, 2018Co-Authors: Barbara Faccini, Mauro Coltorti, Nicolò Colombani, Dario Di Giuseppe, Gianni Ferretti, Micòl MastrociccoAbstract:In this paper we report an overview of the main outcomes of a 3-years experimental cultivation carried out in an Italian reclaimed agricultural field amended with different types of zeolitites (rock containing > 50% of zeolites), under cereals cultivation (Sorghum vulgare Pers, Zea mays and Triticum durum). The aim of the experiment was to exploit the properties of zeolite-rich volcanic rocks (zeolitites) for reducing the excessively high NO3− content in the soil and in Waters flowing out the sub-Surface drainage System of the field and flushing into the Surface Water System, reducing concomitantly also chemical fertilization application rates (up to 50%). Zeolitites were tested both in their natural state and in a NH4+-enriched form, obtained through an enrichment process with NH4+-rich zoo-technical effluents (pig slurry). NO3− content in soils and in Waters discharged through SSDS were periodically monitored during the experimentation and crop yield quantified. Results showed that, for three consecutive cultivation cycles, the overall NO3− concentrations in Water extracts was reduced by 45% in the zeolitite treated soils, while in SSDS Waters the reduction reached the 64%. Notwithstanding the lower N input from chemical fertilizers, crop yield was not negatively affected in the zeolitite amended soils with respect to the control. Zeolitite addition increased thus soil NH4+ retention and probably influenced several pathways of N losses, allowing a better fertilizer use efficiency by plants and a reduction of the overall NO3− concentrations in the Surface Waters.
