1 Supplementary Material the Blue Water Footprint of Electricity from Hydropower B Corresponding Author
Supplementary material The blue water footprint of electricity from hydropower Mesfin M. Mekonnena,b and Arjen Y. Hoekstraa aDepartment of Water Engineering and Management, University of Twente, P.O. Box 217, 7500 AE Enschede, The Netherlands b corresponding author: [email protected] Method The water footprint of electricity (WF, m3/GJ) generated from hydropower is calculated by dividing the amount of water evaporated from the reservoir annually (WE, m3/yr) by the amount of energy generated (EG, GJ/yr): WE WF (1) EG The total volume of evaporated water (WE, m3/yr) from the hydropower reservoir over the year is: 365 WE 10 E A t1 (2) where E is the daily evaporation (mm/day) and A the area of the reservoir (ha). There are a number of methods for the measurement or estimation of evaporation. These methods can be grouped into several categories including (Singh and Xu, 1997): (i) empirical, (ii) water budget, (iii) energy budget, (iv) mass transfer and (v) a combination of the previous methods. Empirical methods relate pan evaporation, actual lake evaporation or lysimeter measurements to meteorological factors using regression analyses. The weakness of these empirical methods is that they have a limited range of applicability. The water budget methods are simple and can potentially provide a more reliable estimate of evaporation, as long as each water budget component is accurately measured. However, owing to difficulties in measuring some of the variables such as the seepage rate in a water system the water budget methods rarely produce reliable results in practice (Lenters et al., 2005, Singh and Xu, 1997). -

NOTES and CORRESPONDENCE Synoptic-Scale Controls of Summer
15 FEBRUARY 2006 NOTES AND CORRESPONDENCE 613 NOTES AND CORRESPONDENCE Synoptic-Scale Controls of Summer Precipitation in the Southeastern United States JEREMY E. DIEM Department of Anthropology and Geography, Georgia State University, Atlanta, Georgia (Manuscript received 15 October 2004, in final form 11 August 2005) ABSTRACT Past climatological research has not quantitatively defined the synoptic-scale circulation deviations re- sponsible for anomalous summer-season precipitation totals in the southeastern United States. Therefore, the objectives of this research were to determine the synoptic-scale controls of wet and dry multiday periods during the summer within a portion of the southeastern United States as well as to assess the linkages between synoptic-scale circulation and multidecadal variations in precipitation characteristics for the study domain. Daily precipitation data from 30 stations for June, July, and August from 1953 to 2002 were converted into 13-day totals. Using standardized principal components analysis (PCA), the study domain was divided into three precipitation regions (i.e., South, Northwest, and Northeast). Wet and dry periods for each region were composed of the top 56 and bottom 56 thirteen-day periods. Composite circulation maps for 500 and 850 mb revealed the following: wet periods were generally associated with an upper-level trough over the interior southeastern United States coincident with strong lower-tropospheric flow into the South- east from the Gulf of Mexico, and dry periods were characterized by ridges or anticyclones over the midwestern and southeastern United States coupled with weak lower-tropospheric flow. Many of the wet periods had surface fronts. Over the 50-yr period, increased precipitation was significantly correlated with increased occurrences of midtropospheric troughs over the study domain. -

Walter, Ronald Elliott, Terry Howell, Daniel Itenfisu, Marvin Jensen ENDORSEMENTS Irrigation Association, 2004 ASCE-EWRI Task Committee Report, January, 2005 ASCE Standardized Reference Evapotranspiration Equation Page ii ABSTRACT This report describes the standardization of calculation of reference evapotranspiration (ET) as recommended by the Task Committee on Standardization of Reference Evapotranspiration of the Environmental and Water Resources Institute of the American Society of Civil Engineers. The purpose of the standardized reference ET equation and calculation procedures is to bring commonality to the calculation of reference ET and to provide a standardized basis for determining or transferring crop coefficients for agricultural and landscape use. The basis of the standardized reference ET equation is the ASCE Penman-Monteith (ASCE-PM) method of ASCE Manual 70. For the standardization, the ASCE-PM method is applied for two types of reference surfaces representing clipped grass (a short, smooth crop) and alfalfa (a taller, rougher agricultural crop), and the equation is simplified to a reduced form of the ASCE–PM. -
