The river Rhine is one of Europe’s busiest waterways and is part of the Rhine-Alpine corridor. In 2018 the river experienced a severe low discharge extreme. This impacted the river’s transport capacity for a period of several months, causing shortages of source materials and fuels in regions far in-land. Historically, prolonged droughts of this...

Sand dams are impermeable water harvesting structures built to collect and store water within the volume of sediments transported by ephemeral rivers. The artificial sandy aquifer created by the sand dam reduces evaporation losses relative to surface water storage in traditional dams. Recent years have seen a renaissance of studies on sand dams...

Due to climate change, drought-flood alternations have become more frequent and more severe in many countries in the world. However, little research has been done on the relationship between flood and drought. Thus, this research aims to investigate whether a relationship exists between multi-year droughts and the floods that follow in the post...

Over the last years the Netherlands has often had to deal with droughts and water shortages during summer. This problem is caused by long periods without rain but with high evaporation rates and is enhanced by groundwater extraction for drinking water. Due to climate change, these droughts are expected to occur more often and become more severe....

To reduce the Urban Heat Island (UHI) effect Green Infrastructure (GI) is seen as a key measure. Though, often the need for water to evaporate is neglected. This study focuses on showing the effects of irrigation and increased soil moisture contents on GI within urban areas to reduce the UHI-effect. ENVI-met, a micro-climate model, is used to...

One of the substantial causes for food insecurity in an area is drought. Drought is a very insidious disaster. Unlike rapid onset disasters, like an earthquake or flood, it increases its grasp over an area over time. The longer the drought lasts, the more an area is destroyed leaving devastating effects that can last many years. The impacts of...

Due to climate change, a new water management policy is considered in the Netherlands. The shift towards greater extremes in both wet periods and dry periods requires a more dynamic policy. It is investigated what effect the placement of a permanent water barrier in the Rijnmond has on the water levels in the Rhine branches, and if this can be...

Drought and subsidence are two out of several water-related urban climate adaptation challenges many cities in the Netherlands currently face. Drought is expected to increase in frequency and extent due to climate change. Therefore, drought is likely to further pressurize (subsiding) urban areas in the coming decades. Although the impact of...

During intense periods of drought, the development of cracks is observed in peat and clay dikes. Asset managers of the dikes increase the inspection frequency in times of drought to be able to monitor these cracks. Significant development of the cracks contributes to the development of different failure mechanisms. In this study, the occurrence...

Droughts are considered to be one of the most damaging, yet least understood, natural hazards of all. Despite their prevalence, a thorough understanding of them lacks because they are such complex phenomena, and their manifestation can differ depending on the region they occur in. Monitoring hydrological variables and processes is imperative for...

A green-blue roof consists of a water storage layer with on top a substrate layer covered with vegetation. Due to the presence of the water storage layer, a green-blue roof is better capable of retaining heavy rain events. A movable valve makes it possible to manage the amount of water on the roof and the timing of drainage from the roof to the...

The stress on global food security is expected to increase. Hence, crop and drought monitoring will become increasingly important in the future. Synthetic Aperture Radars (SAR) are able to penetrate clouds and thus reliably provide data. Despite the extensive literature that can be found on the use of high spatio-temporal resolution SAR data, a...

The 2018 summer drought in Europe was particularly extreme in terms of intensity and impact due to the combination of low rainfall and high temperatures. However, it remains unclear how this drought developed in time and space in such an extreme way. In this study we aimed to get a better understanding of the role of land–atmosphere interactions...

In arid and semi-arid regions of the world, the occurrence of prolonged drought events (megadroughts) associated with climate change can seriously affect the balance between water supply and demand, thereby severely increasing the susceptibility of such regions to adverse impacts. In this study, a simple framework is introduced to estimate...

Study region: The study area is the river basin upstream of the Kariba dam located in the Zambezi River at the border of Zambia and Zimbabwe. Study focus: During the dry season of 2019 in Sub-Saharan Africa, extremely low water levels occurred in the Zambezi. According to news media, locals perceived this drought as the worst in several...

Droughts in a warming climate have become more common and more extreme, making understanding forest responses to water stress increasingly pressing. Analysis of water stress in trees has long focused on water potential in xylem and leaves, which influences stomatal closure and water flow through the soil-plant-atmosphere continuum. At the...

Drought characterization and risk assessment are of great significance due to drought’s negative impact on human health, economy, and ecosystem. This paper investigates drought characterization and risk assessment in the Lempa River basin in Central America. We applied the Standardized Evapotranspiration Deficit Index (SEDI) for drought...

The Netherlands was faced with drought disruption within their Inland Waterways (IWT) in the past few years. The drought of 2018 was so severe that the disruption caused economic losses. As the topic of drought disruption is new, little strategies have been developed to reduce the economic loss due drought disruption. One concept has gained...

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...

This research focuses on the impact of extreme low river discharges, meaning discharges below 1200 m2/s at Lobith. In 2018 extreme low river discharges in the river Rhine led to congestions in the main Dutch part, called the river Waal. The river Waal is an important river for inland navigation, but during low discharges the...
