Abstract The aim of the paper is the identification of the kinds and conditions of retention occurring in the selected of young glacial catchment (the Potok Oliwski) in natural and anthropogenic conditions by means of the mathematic model of Mike She. As a result of the performed calculations it has been possible to determine that the studied area, thanks to the nature-shaped factors, has a high retention potential, which refers to the ground water storage. The conditions of surface retention, in which a great role is played by blind drainage, have been analysed as well. Keywords Retention · Catchment · Edge zone · Area without outflow · Depression
Introduction To approach the problem of water resources in detail, it is necessary to study them from a macro and systematic perspective (Wang et al. 2016). First, new places should be sought, where humans they could tap new resources or apply some technological measures to recover substantial amounts of water that have so far figured as losses in the total balance. One of the latter is employing natural retention to store and then recover water. This can involve not only the surface water cycle, but also the sub-surface one. Among the natural objects that can be employed to store precipitation water and then be used for household and economic purposes are basins without outlets, both of the absorptive and the evapotranspiration type (Major and Cieśliński 2010). All kinds of practices, both technological (small water reservoirs, weirs, gates, etc.) and non-technological (afforestation, tree planting, protective vegetation belts, protection of kettle ponds, country ponds, marshes, etc.)—can help to slow down or stop water while restoring the natural landscape. However, to be able to employ the various forms of retention correctly, one should first identify the conditions that will affect small water cycles and the magnitude of retention in the catchments (Quinton * Roman Cieśliński [email protected] 1

et al. 2003; Brooks 2005). Today, to assess changes in hydrological and climatic conditions considered in global, regional and local level are used all kinds of mathematical models. One of the better models involving different elements of the natural environment of water circulation, including the retention model is Mike She. This model is used, among other things Larsen et al. (2014) for a Danish catchment, Wang et al. (2012) who performed the analysis multi-site calibration, validation and sensitivity of the MIKE SHE Model for a large watershed in northern China, Prucha et al. (2016) who performed a variety of hydrological simulation scenarios for dry areas, Doummar et al. (2012) who made simulation of flow processes in a large scale, Rahim et al. (2012) who made application of
