“…The attributes used in the regionalization of flow characteristics in the pursuit of estimating the flow rate at the ungauged site include proximity, the catchment area, elevation, the slope of the basin or channels, land use, and weather conditions (Monjardin et al, 2017, Razavi & Coulibaly, 2013. In Isahaya reservoir catchment, area, slope, and land use are major aspects affecting flow regime and subsequently informed the choice of the method that could be used in transplanting flowrate characteristics.…”

This paper presents a framework for mapping flow information from the gauged to the ungauged river basins. The calibration and validation of a hydrologic model were conducted to establish basic watershed characteristics. The new framework was then applied to account for the two watersheds' proportionality in their similarity, such as the influence of land use on transplanting flow signatures. Three land-use scenarios-discharges at the ungauged and gauged sites formed the basis of an equation mapping the gauged discharge signal to the ungauged site. In comparison with intermittent observed data, the framework prediction attained a precision of 0.85≥NSE≤0.95, 0.80≥R2≤0.94, 0.56≥bR2≤0.89. Despite considerable differences in the watershed area, slope, soils, and land cover, the framework satisfactorily depicted the variation in flow pulses of each river. In the absence of established hydrological information, this provides an alternative flow estimation at ungauged sites, reducing uncertainties in the regionalization of model parameters.

“…The N.F. provides an alternative method for reasonably estimating discharge at an ungauged location when the number of gauges is limited, and other methods are inapplicable or ineffective.The attributes used in the regionalization of flow characteristics in the pursuit of estimating the flow rate at the ungauged site include proximity, the catchment area, elevation, the slope of the basin or channels, land use, and weather conditions[29] [51]. In the Isahaya Reservoir watershed, area, slope, and land use are important aspects that affect the flow regime and influence the choice of method that can be used to transplant flow characteristics.…”

This paper describes a framework for mapping flow information from a single gauge to the 9-ungauged river basins with distinct attributes. To establish the basic watershed characteristics at the gauged site, a hydrologic model was calibrated and validated against the historical continuous discharge dataset. The framework was then applied to account for the two watersheds' proportionality in their similarity, such as the influence of land use on transplanting flow signatures to the ungauged site. Three land-use scenarios-discharges at the ungauged and gauged sites formed the basis of an equation mapping the gauged discharge signal to the ungauged site. In comparison with intermittent observed data, the framework prediction attained a precision of 0.85 ≥ NSE ≤ 0.95, 0.80 ≥ R 2 ≤ 0.94, 0.56 ≥ bR 2 ≤ 0.89. Despite considerable differences in the watershed area, slope, soils, and land cover, the framework satisfactorily depicted the variation in flow pulses at each of the 9 ungauged discharge sites. In the absence of sufficient hydrological information, for example, the presence of a single gauge, the framework provides an alternative method to estimate flow at ungauged sites, reducing uncertainties in the regionalization of model parameters.
