The influence of various climatic factors on snowmelt runoff was determined through 583 multiple correlations for streams in a Bureau of Reclamation multiple‐purpose reservoir system located in northern Colorado and southeastern Wyoming. The use of highspeed electronic computers facilitated the solution of the equations and the determination of various statistical parameters considered indicative of accuracy. The superiority of using both precipitation and snow‐survey data as primary factors was indicated. Other factors, including winter and spring temperature and melt‐season precipitation, were found helpful in individual cases, but not uniformly. Investigations of factors antecedent to the snow‐accumulation period revealed no significant increase in accuracy. Numerous investigations were also made of different methods of weighting the primary factors.
Six areas define the functional problem of urban water management; and there is also the financial problem. Possible resolutions are integrated and areawide management and their combination. Here are detailed analyses of the conundrum's resolutions.∗
This report of an investigation to determine a multiple correlation equation for use in relating various hydrologic factors is an extremely worthwhile presentation. As the authors point out, there have been numerous papers reporting results of statistical analyses of hydrologic data. However, there have been too few papers devoted to a description of the techniques used in selecting and designing empirical equations for use in regression analysis in hydrologic studies. The recent rapid increase in the application of electronic computers emphasizes the need for increased familiarity with basic mathematical and numerical methods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
