“…The effectiveness of their framework was later confirmed in United States catchments by exploring the physical controls of regional patterns of FDCs Ye et al, 2012). As suggested by Yokoo and Sivapalan (2011), the high flow part of a FDC is highly responsive to precipitation. If so, the Curve Number (CN) method can be used in estimating the high flow part firstly because it is simple and convenient to use (Tedela et al, 2012) and secondly it estimates runoff based on a single CN parameter with an empirical precipitation and runoff relationship.…”

“…Based on the proposed framework by Yokoo and Sivapalan (2011), the MMF was used in estimating flows in the FDC middle component. Therefore, the FDCs of daily measured discharge (Q m ) and MMF were plotted and the two quantities were analyzed at the middle part.…”

“…Therefore, this study aims to develop a methodology for estimating the shape of a FDC in Hawaii Island watersheds following the framework of Yokoo and Sivapalan (2011). Towards this goal, the present study investigates (1) if we can estimate the middle flow part of a FDC from MMF and (2) how can we estimate the high flow part of a FDC from daily precipitation data and the CN method in well-gauged Hawaiian watersheds.…”

“…Its simplicity and ability to project an image of combined watershed information regarding runoff variability leads to it having many applications (Vogel and Fennessey, 1995). As for such FDCs, Yokoo and Sivapalan (2011) suggested a framework for reconstructing FDCs in a modeling approach. They separated a FDC into fast and slow flow parts and suggested that a strong relationship may exist between fast flows and precipitation for the high flow part and slow flows and the mean monthly flow (MMF) for the other part.…”

Abstract:The authors attempted to develop a simple methodology for estimating daily flow duration curves (FDCs) in island watersheds under humid tropic conditions, to realize better water management in data-limited island watersheds. This study disaggregated a FDC into three parts, namely high, middle and low flow parts and estimated each part independently. Based on Hawaiian watersheds, this study developed a methodology for estimating the high flow part using daily precipitation data and the Curve Number (CN) method, whereas we estimated the middle flow part directly from mean monthly flow (MMF) data. The results for the middle flow part showed the MMF data closely tracking the daily FDCs for nine of the eleven studied watersheds. For the high flow part, the results showed that only after calibration of the CN method, were there significant improvements in estimations. These results suggest it is possible to estimate the middle flow part of the FDC with MMF but the high flow part must use a calibrated CN in the CN method. This study also explored the relationship between calibrated CN and estimated absorption capacity of the studied watersheds to find the possibility of estimating suitable CN of a watershed from its geological characteristics.

“…Lastly, the flow duration curve (FDC) plots daily streamflow magnitude (on a log scale) as a function of the percent of time it is exceeded. The FDC can be divided into 3 sections, with the upper third corresponding to flood events and the fast flow response of a catchment, the middle third to the slow flow response of the catchment and its regime curve, and the lower third the low flow response (Yokoo and Sivapalan, 2011). While the upper third of the FDC is mainly related to precipitation intensity, the lower third is more related to properties of the catchment itself .…”

Abstract. Historically, the central Midwestern US has undergone drastic anthropogenic land use change, having been transformed, in part through government policy, from a natural grassland system to an artificially drained agricultural system devoted to row cropping corn and soybeans. Current federal policies are again influencing land use in this region with increased corn acreage and new biomass crops proposed as part of an energy initiative emphasizing biofuels. To better address these present and future challenges it is helpful to understand whether and how the legacies of past changes have shaped the current response of the system. To this end, a comparative analysis of the hydrologic signatures in both spatial and time series data from two central Illinois watersheds was undertaken. The past history of these catchments is reflected in their current hydrologic responses, which are highly heterogeneous due to differences in geologic history, artificial drainage patterns, and reservoir operation, and manifest temporally, from annual to daily timescales, and spatially, both within and between the watersheds. These differences are also apparent from analysis of the summer low flows, where the more tile-drained watershed shows greater variability overall than does the more naturally drained one. In addition, precipitation in this region is also spatially heterogeneous even at small scales, and this, interacting with and filtering through the historical modifications to the system, increases the complexity of the problem of predicting the catchment response to future changes.

Recent hydrologic synthesis efforts have presented evidence that the seasonal water balance is at the core of overall catchment responses, and understanding it will assist in predicting signatures of streamflow variability at other time scales, including interannual variability, the flow duration curve, low flows, and floods. In this study, we group 321 catchments located across the continental U.S. into several clusters with similar seasonal water balance behavior. We then delineate the boundaries between these clusters on the basis of a similarity framework based on three hydroclimatic indices that represent aridity, precipitation timing, and snowiness. The clustering of catchments based on the seasonal water balance has a strong relationship not only with regional patterns of the three climate indices but also with regional ecosystem, soil, and vegetation classes, which point to the strong dependence of these physiographic characteristics on seasonal climate variations and the hydrologic regimes. Building on these catchment clusters, we demonstrate that the seasonal water balance does have an imprint on signatures of streamflow variability over a wide range of time scales (daily to decadal) and a wide range of states (low flows to floods). The seasonal water balance is well integrated into variability at seasonal and longer time scales, but is only partly reflected in the signatures at shorter time scales, including flooding responses. Overall, the seasonal water balance has proven to be a similarity measure that serves as a link between both short-term hydrologic responses and long-term adaptation of the landscape with climate.
