Increasing the Efficiency of the Sacramento Model on Event Basis in a Mountainous River Basin

Application of a GIS based distributed model for rainfall runoff simulations

“…The basin has a nearly symmetric shape, close to an oval shape rather than an elongated shape, which has the effect of generating hydrographs with steep rising limb; as a result, high peak discharges are often observed. The datasets used in the analysis were mainly the Digital Elevation Model (DEM), the Corine Land Cover (2012), and the hydrological soil type, according to SCS (1972) and the work of Bournas and Baltas (2021) were taken into consideration. Other DEM-derived geomorphological and hydrological attributes, such as the slope and streams definition.…”

“…The precipitation datasets of the adjacent to the catchment area rain gauges, depicted in Figure 1, were provided by the National Observatory of Athens network (NOANN) (Lagouvardos et al, 2017), which feature 10-minute precipitation recordings. Finally, the streamflow data were derived from water level measurements by applying a derived rating curve as shown in the work of Bournas and Baltas (2021).…”

“…Along with these, water basin characteristics like soil properties, vegetation cover, watershed topography, soil moisture content, characteristics of ground water aquifer are also considered (Devi et al, 2015). Especially, the development of distributed hydrological models with varying degrees of complexity to address a wide range of scientific questions has become widespread in recent years (Kampf and Burges, 2007;Smith and Gupta, 2012;Bournas and Baltas, 2021).…”
