“…Dichos mecanismos son propios de regiones de clima húmedo, ya sea en la zona templada (Carey y Woo, 2001;Buttle et al, 2004) o en las bajas latitudes (Putty y Prasad, 2000). En España se han estudiado esos procesos hidrológicos en cuencas de montaña pirenaicas (Gallart et al, 1997;Latron et al, 2004), pero bajo condiciones climáticas no estrictamente mediterráneas.…”

“…An actual estimation of runoff volume and peaks is also important for planning different interventions in integrated watershed management and many flood protectionprojects [1,2]. The tasks in relation to estimation runoff volumes and flood peaks can be, however, easily simplified by adopting a modelling concept understanding rainfall partitioning and the principal factors triggering runoff [3][4][5].…”

“…The rainfall-runoff modelling approach is most frequently used in hydrology for estimating the runoff signal which leaves the catchment from the rainfall signal received by the basin [6,7]. Different techniques of the hydrologic modelling approach have been so far adopted in different studies, with some of them focused on an empiricalbasis and other modelling approaches based on the distributed modelling concept [1,8]. The type of the modelling approach normally depends on the purposes, data availability, and ease of use [9,10].…”

“…It is thus imperative to choose a suitable model with a simple structure, minimum input data requirements, and a reasonable precision [1,[10][11][12]. Considering the lack of sufficient data on one hand and the complexity of hydrological systems on the other, a lot of computer-based hydrological models have been developed, such as Soil Water & Assessment Tool (SWAT), Hydrologic Engineering Center-Hydrologic Modeling System (HEC-HMS), Topography based hydrological model (TOPMODEL), The Water Erosion Prediction Project (WEPP) Model, and Annualized Non Point Source Pollution Model (AnnAGNPS) [13][14][15].Those models were developed based on different situations of data availability and ease of complexity.…”

Estimation of runoff is vital forplanning activities in relation to integrated watershed management and flood protection measures. This research was conducted at one of the catchments in Abbay River (upper Blue Nile River) basin to assess the applicabilityof the Hydrologic Engineering Centre Hydrological Modelling Software (HEC-HMS) modelfor simulation of runoff. It was aimed at selecting the best loss and transform methods in the model, as well as testing the applicability of the calibrated model to ungauged watersheds. Two loss methods such as soil conservation service (SCS) and initial and constant methods with two transform methods including SCS and Clark unit hydrographs were considered in the study for selecting the best combinations applicable in the area. While comparing the simulation results of each combination, better results were obtained in the model set containing the initial and constant loss method and SCS unit hydrograph with a Nash-Sutcliff Efficiency (NSE) of 82.8%, R 2 of 0.83, and 10.71% of relative bias errors, followed by initial and constant with Clarks unit hydrograph, and it can be used for similar ungauged watersheds.

“…To learn more about the streamflow-generation mechanisms in the Western Ghats region (mountains located in South India), Putty and Prasad (2000) used a lumped conceptual model based on the variable source-area theory. The results show that flow from dynamic subsurface saturated zones contributes substantially to quickflow: fieldwork and a modified version of the model were necessary.…”

Performance of process-based hydrological models is usually assessed through comparison between simulated and measured streamflow. Although necessary, this analysis is not sufficient to estimate the quality and realism of the modelling since streamflow integrates all processes of the water cycle, including intermediate production or redistribution processes such as snowmelt or groundwater flow. Assessing the performance of hydrological models in simulating accurately intermediate processes is often difficult and requires heavy experimental investments. In this study, conceptual hydrological modelling (using SWAT) of a semi-arid mountainous watershed in the High Atlas in Morocco is attempted. Our objective is to analyse whether good intermediate processes simulation is reached when global-satisfying streamflow simulation is possible. First, parameters presenting intercorrelation issues are identified: from the soil, the groundwater and, to a lesser extent, from the snow. Second, methodologies are developed to retrieve information from accessible intermediate hydrological processes. A geochemical method is used to quantify the contribution of a superficial and a deep reservoir to streamflow. It is shown that, for this specific process, the model formalism is not adapted to our study area and thus leads to poor simulation results. A remote-sensing methodology is proposed to retrieve the snow surfaces. Comparison with the simulation shows that this process can be satisfyingly simulated by the model. The multidisciplinary approach adopted in this study, although supported by the hydrological community, is still uncommon
