Shrimp farming is an important source of income in Vietnam. In the Mekong Delta several shrimp farms are established, due to its stable weather and environmental conditions making it possible to farm throughout the whole year. The farm where this research was done is an extensive culture system. In these systems, the water is exchanged using the...

Foka, E. (author)
The growing agglomeration and climate change are two challenges for the urban areas, which result in the reduction of permeable surface, the increase of surface runoff and a change in the temperature and precipitation patterns. These, in addition to the uncertainty of the climate change, point towards the need for adaptive sustainable solutions....

Ongoing urbanisation and the subsequent extensive use of the urban water system can lead to degradation of its surface water quality. In the Netherlands, urban water bodies often suffer from the manifestations of eutrophication due to (historically) high nutrient loadings. This research focused on the enhancement of surface water quality of semi...

Light is attenuated by materials present in the water column by scattering and absorption. The knowledge of light attenuation and its contributing factors influencing visibility/turbidity is unknown in Singapore waters. This MSc thesis consists of field measurement, laboratory experiment and numerical modelling in 3 parts; parameterisation of...

This study is aiming to improve the understanding of hydrodynamic circulation in large shallow lakes. The Lake Taihu, the third largest lake in east China, is picked up as the study area for three reasons. The basin of Lake Taihu is considered as the most populated and developed area as a backyard of Shanghai. Lake Taihu is a typical shallow...

The water quality of a 5 hectare lake system in Gardens by the Bay, Singapore is modelled. The lake system comprises two lakes, Dragonfly and Kingfisher Lake, connected by a 5 metre wide stream. Inflow is from runoff from the 50 hectare catchment and from pumping from the neighbouring Marina Bay Reservoir at a rate of 20 Ls-1, 24/7. Outflow is...

The worldwide availability of safe and clean drinking water constitutes one of the main challenges of our era. Unfortunately, due to progress-related issues such as global warming, population growth and industrial development, the availability and quality of drinking water is expected to deteriorate in the coming years, posing new threats for...

Rainwater harvesting is the primary source of fresh water on the majority of isolated and volcanic islands in the Eastern Caribbean island chain that lack reliable sources fresh water. Recent research studies have determined that the microbiological quality of rainwater in cistern systems is generally unstable and can lead to serious health...

The water quality of the Brantas river in Indonesia is of concern to several agencies on East Java. These agencies all measure its water quality in their own way in terms of locations, rhythms and parameters. The goal of this thesis is to find out if these agencies measure the same and if not, how these measurements differ. From these...

This study investigates the connection between macro-scale parameters (MSP) and micro-scale water quality parameters (MSWQP) in the Brantas River, employing a multivariate linear regression (MLR) modelling approach. The analysis reveals several critical insights into the complex dynamics of water quality in this river system.<br/><br/>Key...

The Dutch water management system is confronted with a lack of awareness among citizens and further faces the consequences of climate change and urbanisation. New governance structures with high levels of citizen participation are required to be fit for the future. An implementation of participation could be citizen science, which is rather...

In the one-dimensional 'Rhine Alarm Model' differences between the actual travel time of a pollutant-cloud (Tpol), originating from an instantaneous release of an accidental spill, and the travel time, based on the flow velocity (Tflow) is represented by a lag coefficient ß. The travel time of the pollutant Tpol is related to the centroid of the...

Water injection is widely used in the petroleum industry for the increase of hydrocarbon recovery or disposal of wastewater. Water production and injection are the primary mechanisms in Geothermal Energy. Both include injecting water into a porous formation under matrix injection conditions. While maintaining water injection is vital in these...

The Ecostress project has the intention to develop systems and methodologies to observe changes in urban coastal areas. Within this project, the Wadden Sea is taken as a pilot area. The goal is to produce tools to assess human, social and environmental impacts, such as the spatial risk and socio-environmental impacts of coastal urbanization. One...

Driven by solving water shortage problems and meeting the increasing strict regulations of water quality, changes of supply water quality are commonly happening worldwide. These kinds of irregular changes can have impacts on drinking water distribution systems with accumulated material, leading to chemical, physical and microbiological...

For this thesis a hydrochemical groundwater survey was carried out on the Caribbean island of Curaçao in 2020 as part of the NWO SEALINK project. In order to be well-adapted against anthropogenic and natural pressures, Curaçao needs representative data, yet thorough hydrochemical datasets were only sparsely collected in the wet seasons of 1977...

This thesis discusses the use of fast and robust solution methods for advection-dominated advection-diffusion-reaction equations coming from water quality problems. Therefore we look at fluxlimiters by the FCT method in combination with the local-theta approach to increase both the accuracy and the efficiency. The discretized equations (by the...
