“…La técnica de monitoreo batimétrico con ecosonda aplicada para obtener los puntos detallados en la Figura 2, se basa en la medición de la profundidad del agua y el intervalo de tiempo requerido para que las ondas ultrasónicas viajen, a una velocidad conocida, desde un punto conocido a una superficie reflectante (Wernly et al, 2016).…”

“…Con la información batimétrica disponible, es necesario construir las curvas Cota-Volumen y Cota-Área para estimar la capacidad del embalse, de manera que se pueden planificar posibles medidas para controlar los fenómenos de sedimentación como lo son el dragado mecánico o el lavado de un embalse que ha sido planificado para estos propósitos. En este contexto, existe una gran variedad de herramientas computacionales para estimar el volumen y el área de un embalse en base a su batimetría y dada una cota de nivel determinada: las herramientas de diseño asistido tipo CAD (Yakubu et al, 2015), los sistemas de información geográfica (Venkatesan et al, 2012;Wernly et al, 2016) y de ciencia de datos (Fuska et al, 2017;Hollister y Stachelek, 2017).…”

<p>In the management of the regulation volumes of the water resource projected for a variety of benefits (hydroelectric uses, irrigation, drinking water, among others), it is essential to calculate the morphometric variables of the reservoirs to anticipate changes in their morphology and predict how these changes could affect projected achievement. In this document, taking into consideration the fundamental concepts of Integral Calculus, the development of an innovative methodology is presented to obtain the Cota-Volume and Cota-Area curves in reservoirs; the methodology was formulated in R programming language with the help of geographic information tools. A computational optimization was achieved for the processing of the variables of level, area and volume of a regulation body respect to the use of traditional methodologies. To validate the developed tool, the capacity curves of regulation volume of the Minas - San Francisco reservoir located in the south of the Republic of Ecuador were obtained. This reservoir was designed to dislodge its sediments with washing processes. This fact has motivated the continuous monitoring of the morphological conditions of the reservoir to plan maintenance processes due to the loss of volume and to the deposit of particles from its tributaries. In addition, an analysis based on wavelets curves was applied to the digital elevation models obtained from LiDAR techniques and bathymetric echo sounder to demonstrate the sedimentation processes that occur in this body of regulation.</p>

“…The calculation of the volume of water resources requires an assessment of the accuracy of determining the parameter of volume V. In the literature, one can find many formulae defining the accuracy of the determination of the volume of water resource or earth mass m V [7,17]. The selection of a proper algorithm of calculations should be adjusted to the character of the measurement data and type of the specially made model.…”

Summary:Krakow's anthropogenic water bodies make up an attractive element of the city landscape. The largest and most-valuable in ecological, landscape and economic aspects are Bagry, Staw Płaszowski, Zakrzówek, and the complex of water bodies in Przylasek Rusiecki. Especially worth noting is the Bagry Reservoir (Zalew Bagry) located near the city center, which has yet to be thoroughly inventoried despite being used since the 1970s. The scientific studies carried out thus far have covered only selected elements of the geosphere; i.e., investigating the flora and fauna resources (biosphere and hydrosphere), searching for aggregate resources, and drilling the clay and silt by geological-engineering (lithosphere). So far, the underground part has not been geo-morphologically documented, even though Bagry has functioned as an attractive bathing resort and a sporting venue in the center of Krakow for many years. In many scientific works and press articles, a lot of information can be found on selected morphometric parameters; however, these values require verification, as they are not current for the most part and do not reflect the actual situation. Nowadays, surveying teams have measurement and information technology tools that allow for the creation of situation and altitude maps (of the surface) and hydrographical (bathymetric) maps, which will allow for an assessment of the characteristics of the water areas and their adaptation for community purposes (recreation, sport, didactic, education, nature, etc.). This article presents the results of hydrographical measurements of Bagry and a full analysis of the morphometric parameters of the reservoir.

Within the borders of the city of Cracow there are several water bodies that are important and valuable in ecological, aesthetic (landscape), economic and recreational aspect. One of them is the Bagry Reservoir, called Bagry Wielkie, situated in Płaszów, in the neighbourhood of the zone designed for industry, warehouses, transport (railway no. 91) and residential areas. Over the whole period of its existence and use, the water body was subdued to frequent geometric changes. Transformations resulted mainly from the demand of the neighbouring brickyards for clay, gravel and sand exploited for the needs of the development in the area of Płaszów, especially during Nazi occupation and the stage of the fi rst phase of the industrialization of socialist Poland (1950Poland ( -1970. The end of exploitation in 1972 and leaving the excavation without carrying out the process of remediation measures caused the return of ground waters to the state of hydro-geological (spontaneous liquidation of the depression funnel). The change in the level of the water table and a very complicated shoreline, typical in this type of post-exploitation water bodies, often cause the separation of the peripheral fragments of the water body from its main part. This limits the possibility of applying popular bathymetric sets, i.e. echo-sonars fi xed on manned boats, carrying out the process of acoustic probing in water areas. In 1999, the small water body located in the south-west part of the study area, was still an integral part of the Bagry. Nowadays it is separated from the main body with a narrow piece of land. Thus the supplementation of hydrographical documentation required the application of automatic measurement tools. The article presents the results of the application of hydro-drone Smart-Sonar-Boat in making a bathymetric map of this poorly accessible fragment of Bagry, making contribution to the cartographic documentation made by R. Gawałkiewicz (Gawałkiewicz R., 2017). ZALEW BAGRY -CZĘŚĆ 3.
