    Keywords : DEM; skogsstruktur; kantzon; Lidardata; vattendrag; skogsbruk; forest structure; riparian zone; Lidar; forest operations;

    Abstract : I Sverige bedrivs skogsbruk på en stor del av skogsmarken vilket riskerar att påverka miljön i vattendragen negativt. Lokala utströmningsområden i anslutning till vattendrag har extra stor betydelse för ytvattnets kemi. READ MORE

  2. 2. Modeling and analysis of a district heating system containing thermal storage

    University essay from Chalmers tekniska högskola/Institutionen för energi och miljö

    Author : Berna Melissa Akkaya; Dmytro Romanchenko; [2013]
    Keywords : district heating; optimization; modeling; thermal storage;

    Abstract : The need for space heating and hot water in the residential and services sector makes up a major part of the total Swedish energy demand. This need is to a large extent satisfied by district heating (DH). In the future, it is expected that the energy system will include a larger share of intermittent renewable energy sources.
