    • Dams with Hydroelectric Station in Small Rivers: Sediment and Nutrient Retention 

      Vaikasas, Saulius; Lamsodis, Romanas (Hydrology: from research to water management: XXVI Nordic hydrological conference, Nordic Association for hydrology, Riga, Latvia, August 9-11, 2010. NHP report No. 51, 2010)

    • Fr Number for smallHydroelectric Station: Impact on Biotic Environment 

      Vaikasas, Saulius; Sabas, Gintautas; Palaima, Kęstutis (Hydrology: from research to water management: XXVI Nordic hydrological conference, Nordic Association for hydrology, Riga, Latvia, August 9-11, 2010. NHP report No. 51, 2010)

    • Hydraulic criteria and estimation of the hydropower plant (HPP) operation impact on the river environment 

      Vaikasas, Saulius; Palaima, Kęstutis; Sabas, Gintautas (8th International Conference "Environmental Engineering", May 19-20, 2011, Vilnius, Lithuania CD, 2011)
      Interaction between a river and its environment is crucial, and negative impact of a HPP operation on the environment must be estimated. In order to be able to evaluate this impact, hydraulic parameters such as velocity, ...

    • Mathematical modelling of flow dynamics of the urban river Nevezis in Kedainiai 

      Vaikasas, Saulius (The 7th International conference "Environmental engineering": selected papers, May 22-23, 2008 Vilnius, Lithuania. Vol. 2, 2008)
      The dynamics of flow velocities and water level in the Nevėžis River in Kėdainiai was estimated by applying a hydraulic-mathematical model DELTA. It was established that there were no conditions for a non-desirable riverbed ...

    • Methods of increasing suspended sediment deposition in the Nemunas delta 

      Rimkus, Alfonsas; Vaikasas, Saulius (The 7th International conference "Environmental engineering": selected papers, May 22-23, 2008 Vilnius, Lithuania. Vol. 2, 2008)
      Floods in the Nemunas delta inundate the bright areas of the valley, where the significant part of the sediments brought by water is deposited. It decreases the pollution of water getting into the Curonian Lagoon and the ...

    • Modelling the impact of small hydropower dam on sediment retention in the river Virvyte 

      Vaikasas, Saulius; Rimkus, Alfonsas (Environmental engineering : the 8th international conference, May 19-20, 2011, Vilnius, Lihtuania: selected papers. Vol. 2 : Water engineering. Energy for buildings, 2011)
      The hydroelectric power plants (HPP) are a valuable source of renewable energy; however they negatively impact the environmental conditions in the river. The paper presents investigation of the ways to coordinate these ...

    • The effect of lime admixture to trench backfill on chemical composition of drainage water 

      Šaulys, Valentinas; Bastienė, Nijolė (The 7th International conference "Environmental engineering": selected papers, May 22-23, 2008 Vilnius, Lithuania. Vol. 2, 2008)
      The field studies on the impact of lime admixture into trench backfill on the chemical composition of drainage water were conducted in a site located in southwestern Lithuania. Heavy-textured clay loam soils were drained ...
