Groundwater is an essential source of drinking water, and it often contains contaminants in the form of dissolved metal ions that pose health risks and affect its suitability for consumption. Removal of these contaminants by conventional treatment methods, such as oxidation and filtration, results in additional treatment steps for managing...

The integrated management of river catchments is a challenge to be addressed by many water authorities, where some of them even today do not yet incorporate the aquifers’ status in decision-making. This situation has led to the depletion of many aquifers, deeply affecting the drinking water supply, agriculture, and industries. This challenge is...

Groundwater (GW) makes up roughly half of the global drinking water supply. Conventional iron removal in GW treatment produces approximately 10,000t/d of iron sludge. Iron sludge consists of low-density flocs with low to no commercial value and causes frequent energy intensive backwashing of the rapid sand filter. This study aimed to explore the...

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...

Groundwater extraction has increased significantly in Nepal. In combination with climate change, this might lead to accelerated groundwater resource depletion. No recent research has been done in the assessment of these resources in the Banke district development area in the Terai. This study aims to assess whether the intensification of...

Like many cities in sub-Saharan Africa, Kumasi, Ghana is facing greater groundwater demands in part due to rapid urbanization. However, currently Ghana does not systematically monitor groundwater, which poses a challenge in management and implementation of science-based policy. Additionally, coordination among stakeholders in Ghana’s water...

The Netherlands has suffered form three successive dry summers resulting in a lowering of the groundwater table, causing water shortage. Also in the area of Water BoardDe Dommel, locatedwithin the province of Brabant, water shortage is a common problem. This results in water abstraction restrictions for farmers in the crop season every year....

Groundwater is an essential ingredient in farming, knowledge about how this is expected to change over time can help farmers improve yields and save water. Predictions about the groundwater level can be made using a mathematical model. This model takes into account the precipitation and evaporation, the flux towards a deeper aquifer and flux to...

The removal of iron from groundwater is essential to avoid aesthetic issues of the produced drinking water and to reduce maintenance cost of the system. The most applied iron removal method of oxidation and filtration produces large volumes of aqueous iron sludge of little value and the method is more likely to fail at high iron concentrations....

The goal of this study was to get a better understanding of the current groundwater drainage in New Orleans, Louisiana. An analysis was conducted on the interactions between groundwater drainage and different water infrastructure systems like: the sanitary sewer system, the storm water drainage system, and the drinking water system. Due to the...

In the winter of 2014 upon 2015 the Hondsbossche dike, between Petten and Camperduin in the Netherlands, has been transformed into a dune area through sand replenishment at the seaside of the dike. The area inland has been appointed as a Natura-2000 area because of the highly appreciated ecological value. A reduction of saltwater seepage would...

Aquifer Thermal Energy Storage (ATES) is a geothermal technique that is an important component in the transition towards renewable energy in the heating and cooling industry, which accounts for half of the world's energy consumption. However, the technology has not yet been implemented in many countries. The main reason is that extensive...

Due to climate change, extreme phenomena like droughts are going to be intensified. Even though droughts in agriculture have been studied, regarding urban environment their consequences are rather unexplored. Cities are susceptible to droughts and the estimation of their vulnerability is the first step for their protection. The objective of this...

The city of Kolkata in India is undergoing rapid urbanization and expansion. As the city expands and engulfs its neighboring areas, it threatens the sustainability of natural resources in peri-urban areas – spaces that are gradually transitioning from rural to urban areas. One such natural resource, groundwater, forms the lifeline of peri-urban...

Estimating groundwater levels spatially using time series analysis. With time series analysis a response function of an observation well is determined. The response function is used to calibrate a conceptual groundwater model. This conceptual model is used to estimate groundwater levels in an area.

Globally, growing demand for fresh water and declining water availability puts significant pressure on water resources. Due to rapid urbanization and insufficient water resource planning and waste water management, the Kathmandu Valley (Valley) is facing both a water quantity and quality crisis. Annually, groundwater extractions in the Valley...

Calibration of groundwater models can be done manually by comparing the measured and computed groundwater heads or automatically using algorithms which do the work for you. Modules for this purpose are included in or linked externally to traditional groundwater modelling software and used. One such module PEST (Parameter ESTimation) uses the...

First estimations for the groundwater recharge in the Chindwin basin in Myanmar are presented in this report. This estimations are based on base flow separation and a SWAT model. Multiple base flow separation methods are applied and these are compared with the base flow produced by the SWAT model. This first estimations show a range of 248-670...

Inhabitants and ecosystems in delta areas are becoming increasingly vulnerable to the effects of subsidence, triggered both by natural causes and anthropogenic causes. Yangon is a city in the Irrawaddy delta in Myanmar where little is known about the true extent of this hazard, while its effects can potentially harm millions of its inhabitants....
