Abstract: AbstractAn innovative method is presented and demonstrated for analyzing spatially distributed water quality measurements to identify persistent sources of contamination within a waterbody. The method consists of first ...

Abstract: AbstractThe standard curve number method is based on an initial abstraction factor, λ, equal to 0.2, while field measurements have shown that λ can vary substantially between catchments, and measured values are typically ...

Abstract: AbstractMethods for estimating curve numbers from field measurements are investigated. It is shown that for the same calibration data set the curve number (CN) estimated using the median method will generally be greater ...

Abstract: Abstract A kinematic model of the flow dynamics and nutrient transport in a long and narrow lagoonal estuary with multiple canal discharges and tidal inlets is developed and demonstrated for the nutrient-impaired segments ...

Abstract: The assumption that normalized 24-h rainfall distributions are independent of return period is investigated. The results of this study show that this assumption is justified in the interior region of the eastern United ...

Abstract: Estimation of intensity-duration-frequency (IDF) functions at ungauged locations is sometimes done using the method introduced by Chen in 1983 [Chen, C. 1983. “Rainfall intensity-duration-frequency formulas.” J. Hydraul. ...

Abstract: The conventional method of delineating wellhead protection areas using travel times is not well suited for application in wellfields containing seepage lakes. The concentration factor is identified as an intrinsic vulnerability ...

Abstract: AbstractConventional methods of identifying clusters of hydrologic time series are based mostly on using a Euclidean distance measure. Such approaches agglomerate time series with similar means, and the temporal fluctuations ...

Abstract: This study identifies five normalized depth-duration functions (NDDFs) that can be used to represent the rainfall characteristics in various regions of the United States. An analysis of the NDDFs at 9,24 hydrometeorological ...
