Spatial variability of leachate flow and distribution in a landfill stabilized by leachate recirculation

Recirculation and infiltration of leachate in landfills are performed to accelerate the process of stabilizing organic matter in waste. At landfill De Kragge (Bergen op Zoom, the Netherlands), leachate recirculation and infiltration measures started in March 2018. This research aims to provide insight related to leachate flow throughout the...

Quantifying the settlement of an aerated landfill using remote sensing methods

As part of the Dutch sustainable landfill project iDS, two compartments of the Dutch landfill Wieringermeer have been treated by in-situ aeration since 2017. The chosen method of aeration is over-extraction, where suction pressure is created causing ambient air to intrude into the landfill. Aeration induces enhanced settlement due to the...

Spatial and temporal variability of hydrological behaviour and leachate composition in a landfill stabilized by in-situ aeration: An experimental and numerical study on the cause and mitigation of reduced aeration efficiency

"Landfills form the final stage in waste processing and are sources of multiple environmentally harmful emissions. Due to the biodegradation of organic material, methane, a strong greenhouse gas, is released into the air and soluble pollutants, like ammonium or heavy metals, are flushed out of the landfill waste. In modern landfills, the waste...

Feasibility study of flushing To Lich River with Red River water through West Lake

The goal of this study is to examine the feasibility of this solution, from a water quality and hydraulic point of view. Firstly, the current state of the three water bodies was investigated and a stakeholder analysis was conducted to look into the social and political context. Secondly, the effect of the solution on the water quality in the WL...

Hydrological and hydrodynamic processes and their impact on spatial characteristics of Terminos Lagoon, Mexico

Terminos Lagoon is the biggest and ecologically most important fluvial-lagoon system of the southern Gulf of Mexico. Rivers, sea and meteorology all influence the lagoon, variable over the year, resulting in a complex situation. To protect this area, it is crucial to know how different hydrological processes, hydrodynamic processes and spatial...

Flood Prevention Guayaquil: A feasibility study on local stormwater storage and the effect of sea branch closure to prevent pluvial and coastal flooding

The city of Guayaquil suffers from regular floods. During the wet season, typically from late December until late April or early May, multiple floods per week can occur. Mainly the excessive rainfall in combination with high tide penetrating into the city results in a high flood risk, but some flood-prone areas can also flood in case of spring...

Effect of movement on the settlement of fluid mud: None

This thesis describes the research about the effect of movement on fluid mud. This was done by exposing several samples of fluid mud from the port of Hamburg to different types of movement for an extended amount of time. It was found that when fluid mud is exposed to kinetic energy of the type used in this experiment, particles will arrange...
