1California Simulation of Evapotranspiration of Applied Water and Agricultural Energy Use in California显示文摘The California Simulation of Evapotranspiration of Applied Water (Cal-SIMETAW) model is a new tool developed by the California Department of Water Resources and the University of California, Davis to perform daily soil water balance and determine crop evapotranspiration (ET c ), evapotranspiration of applied water (ET aw ), and applied water (AW) for use in California water resources planning. ET aw is a seasonal estimate of the water needed to irrigate a crop assuming 100% irrigation efficiency. The model accounts for soils, crop coefficients, rooting depths, seepage, etc. that influence crop water balance. It provides spatial soil and climate information and it uses historical crop and land-use category information to provide seasonal water balance estimates by combinations of detailed analysis unit and county (DAU/County) over California. The result is a large data base of ET c and ET aw that will be used to update information in the new California Water Plan (CWP). The application uses the daily climate data, i.e., maximum (T x ) and minimum (T n ) temperature and precipitation (P cp ), which were derived from monthly USDA-NRCS PRISM data (PRISM Group 2011) and daily US National Climate Data Center (NCDC) climate station data to cover California on a 4 km×4 km change grid spacing. The application uses daily weather data to determine reference evapotranspiration (ET o ), using the Hargreaves-Samani (HS) equation (Hargreaves and Samani 1982, 1985). Because the HS equation is based on temperature only, ET o from the HS equation were compared with CIMIS ET o at the same locations using available CIMIS data to determine correction factors to estimate CIMIS ET o from the HS ET o to account for spatial climate differences. Cal-SIMETAW also employs near real-time reference evapotranspiration (ET o ) information from Spatial CIMIS, which is a model that combines weather station data and remote sensing to provide a grid of ET o information. A second database containing the available soil water holding capacity and soil depth information for all of California was also developed from the USDA-NRCS SSURGO database. The Cal-SIMETAW program also has the ability to generate daily weather data from monthly mean values for use in studying climate change scenarios and their possible impacts on water demand in the state. The key objective of this project is to improve the accuracy of water use estimates for the California Water Plan (CWP), which provides a comprehensive report on water supply, demand, and management in California. In this paper, we will discuss the model and how it determines ET aw for use in water resources planning.Morteza N Orang Richard L Snyder Shu Geng Quinn J Hart Sara Sarreshteh Matthias Falk Dylan Beaudette Scott Hayes Simon Eching 2013Journal of Integrative Agriculture2013,12,8:3
2AVO分析新方法及其在西班牙Guadalquivir盆地中的应用显示文摘本文介绍了一种新的AVO方法,该方法允许解释员处理实际数据(这归因于拟3-D可视化模块),避免了单独根据地震处理技术带来的种种限制。研究区(图1)位于西班牙西南部陆上Guadalquivir盆地。该盆地是一个与Betic褶皱带和向南的逆冲断层带(活动边缘)有关的前陆盆地,它位于向北延伸的古生代稳定边缘(被动边缘)上。主要储集层是上中新统的浊积岩,砂岩平均孔隙度为20%~25%。在这一地区发现了大量的天然气。Consuelo García Mojonero ngela Echánove Hornos 毛宁波 2000国外油气勘探2000,12,2:3
3Effect of unburned carbon content in fly ash on the retention of 12 elements out of coal-combustion flue gas显示文摘The aim of this study was to evaluate whether unburned carbon particles present in fly ash can help in the retention of S,Cl,Br,As,Se,Cu,Ni,Zn,Ga,Ge,Rb,and Pb out of flue gas during the coal combustion at fluidised-bed power station where the coal was combusted along with limestone.The competitive influence of 10%-25% CaO in fly ashes on the distribution of studied elements was studied as well to be clear which factor governs behaviour of studied elements.Except of S(with significant association with CaO) and Rb and Pb(with major affinity to Al2O3) the statistically significant and positive correlation coefficients were calculated for the relations between unburned carbon content and Br(0.959),Cl(0.957),Cu(0.916),Se(0.898),Ni(0.866),As(0.861),Zn(0.742),Ge(0.717),and Ga(0.588) content.The results suggest that the unburned carbon is promising material in terms of flue gas cleaning even if contained in highly calcareous fly ashes.Lucie Bartonov Bohumír ech Lucie Ruppenthalov Vendula Majvelderov Dagmar Juchelkov Zdeněk Klika 2012Journal of Environmental Sciences2012,24,9:3
