“…They are very flexible as, due to their irregular structure, they are able to map regions of high heterogeneity with more data points than smooth terrain and thus avoid redundancy and increase data-storage efficiency DeVantier and Feldman, 1993). TINs also proved to be useful in a number of hydrological applications (e.g.…”

Abstract. The characteristics of a landscape pose essential factors for hydrological processes. Therefore, an adequate representation of the landscape of a catchment in hydrological models is vital. However, many of such models exist differing, amongst others, in spatial concept and discretisation. The latter constitutes an essential pre-processing step, for which many different algorithms along with numerous software implementations exist. In that context, existing solutions are often model specific, commercial, or depend on commercial back-end software, and allow only a limited or no workflow automation at all.Consequently, a new package for the scientific software and scripting environment R, called lumpR, was developed. lumpR employs an algorithm for hillslope-based landscape discretisation directed to large-scale application via a hierarchical multi-scale approach. The package addresses existing limitations as it is free and open source, easily extendible to other hydrological models, and the workflow can be fully automated. Moreover, it is user-friendly as the direct coupling to a GIS allows for immediate visual inspection and manual adjustment. Sufficient control is furthermore retained via parameter specification and the option to include expert knowledge. Conversely, completely automatic operation also allows for extensive analysis of aspects related to landscape discretisation.In a case study, the application of the package is presented. A sensitivity analysis of the most important discretisation parameters demonstrates its efficient workflow automation. Considering multiple streamflow metrics, the employed model proved reasonably robust to the discretisation parameters. However, parameters determining the sizes of subbasins and hillslopes proved to be more important than the others, including the number of representative hillslopes, the number of attributes employed for the lumping algorithm, and the number of sub-discretisations of the representative hillslopes.

“…Since so much of hydrology is linked to processes at the Earth's surface, the connection with the topographic, computer-based methodology known as GIS was a predictable step in the evolution of hydrological sciences (DeVantier and Feldman 1993). A GIS links land cover data to topographic data and to other information concerning processes and properties related to geographic location.…”

“…The application of GIS in natural resources and engineering can be traced back to 1980-1990, and since then, continued efforts have been put into research and development and exponential growth has occurred in GIS applications in natural resources, particularly land and water resources. The review papers of DeVantier and Feldman (1993) and Tsihrintzis et al (1996), dealing with application of GIS in hydrology and water resources, are noteworthy. The automatic characterization of stream networks is a necessary preliminary step for many computer-based hydrologic and geomorphic models (e.g.…”

In recent years, a vital part of water resources management plans is the implementation of hydrologic models. A wellknown example is the Soil and Water Assessment Tool most recognized as SWAT model. SWAT was applied in Thasos Island to simulate the water yield and highlight the most significant of the local torrents. The produced map identify four significant torrents: "Prinos" torrent, "Genna-Maries" torrent, "Limenaria-Kastrou Lakos" torrent and TheologosDipotamos" torrent. In addition, a field survey was conducted at the specific torrents to evaluate the results of the model and select the proper ones for further study and management plans in order to store surface water for other purposes and needs of the residents.Keywords: SWAT, field survey, torrent discharge, management plans, Thasos ____________________________________________________________________________________________ IntroductionHydrology is a science that requires spatial data in order to compose water resources management plans. The hydrological models are very important for this purpose and they are used worldwide and frequently in such applications [1]. The processing speed while using complex calculations to estimate the various hydrological phases is a major advantage of hydrologic models [2]. Various hydrological models have developed in recent years with the ability to directly incorporate geographic data through its integration with Geographic Information Systems (GIS) [3]. The GIS technology has the potential of the collection, storage, processing, analysis and visualization of different data sets with geographical reference. Furthermore, using GIS allows visualization of the spatial distribution of the components of the hydrological cycle and the simulation elements of geographic space as they are arranged in nature [4]. A wellknown model of this category is the Soil and Water Assessment Tool [5] through its interface with GIS (ArcSWAT). SWAT was developed for modeling hydrologic basins by taking into account the meteorological, geographical, geological and soil characteristics, land use and management practices. This study describes the application of SWAT in Thasos Island in order to simulate the torrent discharges of the local torrents. Materials and MethodsSWAT is a hydrologic model developed to predict the water yield and torrent discharge of a basin [6]. It is very useful software because it is manageable through a GIS interface named ArcSWAT [7]. The hydrologic cycle is given as the following (Eq. 1)where t is the simulation period, SWt is the soil water content after the simulation period, SW 0 is the soil water content at the beginning of the simulation period, and R day , Q surf , ET day , w day and Q gw are daily values (in millimeters) for precipitation, runoff, evapotranspiration, infiltration and return flow, respectively. SWAT requires the Digital Elevation Model (DEM) (Fig. 1) for the creation and the delineation of watersheds. According to the properties of the DEM, SWAT proposes a minimum threshold value which...
