Remote prediction of soil types: A working methodology to predict Unified Soil Classification System (USCS) classes based on total geological history

The Dutch Ministry of Defence is interested in developing a tool or workflow that can be used to remotely predict Unified Soil Classification System (USCS) classes of any area to aid mobility-related decisions. Therefore, this study was initiated by Cohere Consultants in collaboration with NEO, a Dutch remote sensing company and Utrecht...

The influence of vertical loading on the lateral behaviour of rigid monopile foundation in clay soil: An analysis using 3D Finite Element Modeling

Monopiles with large diameter (larger than 6 m) and low aspect ratio (less than 6) are increasingly used in offshore wind farms. These foundations demonstrate a rigid response under lateral loading. The validity of the existing design methods, that are based on small diameter flexible piles, has been questioned by both the industry and...

The Influence of Grout Installation Parameters on Shaft Bearing Capacity of Screw-Injection Piles

In modern piling technology screw piles are used as a type of deep foundation for engineering structures, with the principal benefit of using said piles is that they offer an installation method that is virtually noise and vibration free. This makes these piles ideal for construction works in urban areas where surrounding structures can be...

Simulation of fluid flow through fractured rock, a smeared approach

Geothermal energy reservoirs can be used as sources of renewable and sustainable energy. The concept of geothermal technology relies on the harvesting of heat from the deep rock by injecting fluid that circulates through the porous, fractured reservoir rock between the injection and production boreholes, and thereby transports the heat to the...

Effect of Mineral Scaling on Geothermal Wells: Carbonate Scaling

As of 2040, Energy Information Administration (EIA) expects an increase of 28% in world energy consump- tion. The majority of this consumption is projected to account from developing countries such as India, China and other third world countries since the economy is increasing rapidly. [3]<br/>In order to overcome this fast increase, the human...

Engineering a horizontal layer of reduced permeability using Al-DOM precipitation

Leakage of contaminants to the subsurface is a potential threat to groundwater and is a major problem with storage tanks. When the contaminant reaches the groundwater, it can be subjected to subsurface flow due to which a contaminant plume may form and the contaminant can spread. In this research, it was investigated if a horizontal layer of...

Groundwater and solute transport modelling study Vosdonk Noord at Etten-Leur: Examining the effect of two implementation methodologies for highly heterogenic shallow subsurface characteristics

The industrial site of Vosdonk Noord at Etten-Leur in the Netherlands consists of a large soil contamination in combination with highly heterogenic shallow subsurface soil characteristics. In this report, we study the groundwater flow and solute transport behaviour at this project location. Throughout this process, knowledge is gathered about...
