2. 1. Evaluation of Modern Irrigation Techniques with Brackish Water

   Author : Tarek Selim Aboulila; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Soil water; Soil Salinity; Drip irrigation; HYDRUS-2D 3D; El-Salam Canal; Egypt.;

   Abstract : Modern irrigation techniques are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. READ MORE

4. 2. Data preparation, hydrodynamic and contaminant transport shallow-water simulations of Lake Victoria

   Author : Seema Paul; Vladimir Cvetkovic; Jesper Oppelstrup; Roger Thunvik; Felix Mtalo; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake bathymetry model; Steady-state analysis; Numerical model validation; Lake water balance; Correlation and seasonal variations; Solute transport; Vattendjupskarta; Validering av numerisk modell; Vattenbalans; Korrelationer och säsongs-variation; Transport av lösliga ämnen; Mark- och vattenteknik; Land and Water Resources Engineering;

   Abstract : This study explores shallow lake numerical hydrodynamic processes that support model development and validation, extreme events and effects of water circulation in Lake Victoria. Lake Victoria is the second largest freshwater lake in the world, and the largest in East Africa. READ MORE

5. 3. System for water driven down-hole hammer drilling

   Author : Göran Tuomas; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

   Abstract : Drilling with water driven down-hole hammers is a recently developed method for competitive production of boreholes. The technology requires large flow rates of preferably high quality fluid to drive the hammer tool. One method to reduce the consumption is to process and recycle the used drilling fluid. READ MORE

6. 4. Efficient Management of Water Utilities : Sustainability Analysis of Swedish Performance

   Author : Nasik Najar; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainability index; reinvestment; facilities status; climate adaptation and flood security; ; water utility in Sweden;

   Abstract : In Sweden, a sustainability index (SI) has been used since 2014 as an internal benchmark management tool to analyse and steer municipal water and wastewater (WW) activities toward sustainability. A consistent trend in national results from SI across all years is that while day-to-day operations are working well, there are deficiencies in strategies for long-term planning. READ MORE

7. 5. Pit lake water quality and hydrology : Insights from case studies and modelling of pit lakes in northern Sweden

   Author : Oscar Paulsson; Anders Widerlund; Lars Lövgren; Adam P. Jarvis; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geokemi; Applied Geochemistry;

   Abstract : As extraction techniques are improving an increased number of low grade deposits can be economically mined. However, this also means that the number of open pit mines will increase and as a result the number of pit lakes as well. READ MORE
