1. 1. Probabilistic Assessment of Pile Drivability in Swedish Soils

   University essay from KTH/Jord- och bergmekanik

   Author : MAEDEH ALINEJAD KORDMAHALLEH; [2020]
   Keywords : Pile refusal; Monte Carlo method; probabilistic model; boulder.;

   Abstract : Site investigations are often performed prior to the design of pile foundations with the aim to collect data regarding soil properties including boulder content. The obtained data is typically limited due to non-homogeneous characteristic of the soil. READ MORE

3. 2. Tree cover and tree traits affects soil carbon and soil compaction in parklands in central Burkina Faso

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Gustaf Dal; [2016]
   Keywords : Burkina Faso; soil; soil organic carbon; dry bulk density; parklands; trees; agroforestry; vegetation density; tree density;

   Abstract : Burkina Faso is a country with an insufficient agricultural production and this is partly due to the fact that the population is growing and also because of environmental factors such as drought, erosion and poor soils. The most common agricultural system in this part of the world is the parkland which can be defined as farmlands with scattered well-grown trees. READ MORE

4. 3. Att läsa brandspår i skogslandskapet: olika underlag för att förstå naturlandskapets branddynamik

   University essay from SLU/School for Forest Management

   Author : Anders Dahlberg; [2016]
   Keywords : ASIO; brandspårsfrekvens; skogsbrand;

   Abstract : The purpose of this study is to explore different methods to understand the local history of past fire disturbance regimes in a forest management unit. Focusing on the Bergslagen region in south-central Sweden, which has a very long history of forest management, the frequency of occurrence of fire scars on living trees, burned wood, and macroscopic charcoal in the litter layer and in small peat bogs, were studied in landscape strata different with different biophysical characteristics affecting the probability of fire.

5. 4. Near-surface stratigraphy of till and glacifluvium near Knaften, northern Sweden : Identifying small-scale stratigraphy using ground-penetrating radar

   University essay from Institutionen för ekologi, miljö och geovetenskap

   Author : Holger Jacobson; [2013]
   Keywords : Ground-penetrating radar; small scale; near surface; stratigraphy; late Weichselian; grain-size comparison;

   Abstract : The aim of the study was to assess the possibilities in using ground-penetrating radar to identify small-scale stratigraphy in the upper 1 m of a soil profile and to statistically identify differences in the stratigraphic units discovered using the GPR unit. The study area is ca 15 km southwest of Lycksele near a gravel pit on the banks of Örån. READ MORE

6. 5. Uncertainty and sensitivity analysis in soil strata model generation for ground settlement risk evaluation

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Pan Minyi; [2013]
   Keywords : Monte Carlo simulation; kriging; soil strata; sensitivity analysis; risk analysis; uncertainty analysis; physical geography; Earth and Environmental Sciences;

   Abstract : Popular summary: Ground settlement due to groundwater drainage during construction is important to be considered since ground settlement may cause severe building damages. The calculation of ground settlement contains several parameters with uncertainties, e.g. READ MORE
