The aim of the project is to optimise the design of geosynthetic-reinforced timber piled embankments, a.k.a. light embankment piling. The project is financed by Branschsamverkan i Grunden.
The project focuses on describing the effect of suction on heave and 2D-thermal modeling. This project is funded by BVFF.
The project aims to study how frequency data used to detect defects in tracks and ballast can also be used to describe the embankments properties for larger sections.
In this project, the influence of 3D effects on slope stability analysis will be studied focusing on extend of excavations and distance to the embankment to identify scenarios. The findings can be helpful to improve current engineering practice.
Small and medium sized ports (SMP) represent a “hidden” potential in Baltic Sea Region (BSR). If the ports handling less than 10 million tons of cargo are classified as SMPs there are about 160 small and medium-sized ports in Baltic Sea Region handling in total 270 million tons of cargo (1/3 of total volume in BSR).
Small and medium-sized ports (SPM) compose a significant share of the Baltic Sea Region port network. They also handle remarkable amount of cargo and thus play a notable role in local and regional economies in the area (100 – 300 million tons annually depending on definition of SMP).
- thermal treatment for contaminate concentration and transformation of waste to value.
The global tendens is a warmer climate and with that comes problems with thaw on roads.
My work is a part of the project dealing with dust generation and dust spreading around mining areas. Case study is provided by LKAB Company. The work is carried out in close cooperation with my colleague Qi Jia and supervision is provided by professors Nadhir Al-Ansari and Sven Knutsson.
Rainwater harvesting (RWH) is an old technique experienced in several countries. Some of the earliest RWH constructions in history were found in Iraq.
Mosul Dam is one of biggest dams on Tigris River in Iraq, which is located in northern part of Iraq, about 60km north of Mosul city.
This research is aimed to study the design and construction of hazardous waste landfills with respect to the long term performance. The main purpose of the design and construction of these facilities is to isolate such wastes from the biota in the form of tightly designed landfills. Hazardous wastes can be defined as the waste that causes substantial or potential threats to biotic receptors. These wastes have properties that make the waste to be considered as hazardous; ignitability, corrosivity, reactivity and toxicity. Chemical wastes and low level radioactive waste like Depleted Uranium (DU) are considered as hazardous waste and contained in the form of near-surface landfills.
In this research project sediment distribution in Mosul dam reservoir is investigated. Mosul dam is one of the largest dams in Iraq located on the Tigris River in northern Iraq at a distance 50km north the Mosul city as shown in map.
In recent years, the growth of islands in Tigris River increase due to the shortage of incoming water especially at Baghdad City. This led to choking in river cross sections and reduces the river’s ability to pass an extra flood wave along the major cities in addition to problems of deposition at intake of water treatment plants. To overcome this kind of problems, precise engineering study for causes of sediment deposition and rate of deposit are required. One of the powerful tools for such a solution is the application of mathematical models.
The research project deals with methods to more effectively use limited amounts of snow in a warmer climate with shorter periods of winter. For the tourism industry it is of great importance to have snow early in the winter season and to be able to guarantee the right amount of snow with the right quality.

Dredging of several millions cubic metre of sediments in ports and fairways to increase depth to big vessels and ships in Baltic sea in the near future needs high attention in handling many of these ‘hot-spots’ of highly contaminated sediments.
Dam safety is an important issue and it is relevant for WRD (Water Retension Dams) and tailings dams. Large unexpected movements indicate lack of performance and ongoing processes within the structure that are not known and /or not desirable.
Many by-products from mining processes are fine grained silty soils. The materials are known as “tailings”.

Long-Term Subsidence is a major problem for road and rail expansion in areas with sulphide soils. Sulphide soils are mainly located along the northern coast. In a research project that runs from 2008 - 2013 studied subsidence of sulphide soils to reach important new knowledge for future infrastructure projects.
