Water dynamics in the Klaipėda strait
(Aplinkos inžinerija : Vilniaus Gedimino technikos universiteto mokslo žurnalas, 1998)Klaipėdos sąsiauris jungia Kuršių marias ir Baltijos jūrą. Tai akvatorija , kurioje vyksta intensyvi nenutrūkstama skirtingų vandens masių cirkuliacija. Kiekvienais metais apie 23 km gėlo vandens išteka į Baltijos jūrą, o ... -
Water hammer simulation using simplified convolution-based unsteady friction model
(Water: Special issue: About an important phenomenon—water hammer, 2022)Omission of frequency-dependent hydraulic resistance (skin friction) during modelling of the water hammer phenomenon is unacceptable. This resistance plays a major role when the transient liquid flow occurs in rigid-walled ... -
Water loss management experience of Lithuania
(Bulletin of National University of Water Management and Nature Resources Use : collection of scientific papers = Вестник национального университета водного хозяйства и природопользования : сборник научных трудов, 2015)This article presents some general techniques for real water loss reduction and the results of tests on the ways for reduction of apparent water losses in Lithuanian water supply systems. It has been determined that the ... -
Water management tasks in the summer polders of the Nemunas lowland
(Irrigation and drainage, 2006)Surplus water during floods as well as the low level of the soil surface determine the complicated ecological, economic and demographic conditions in the Nemunas delta. Subsequently, it leads to different types and intensity ... -
