The Amazon rainforest is among the most vital ecosystems on earth, holding about a quarter of the global terrestrial carbon sink. Since 2005, three 100-year return period droughts have occurred, the likes of which have the potential to turn the forest from a carbon sink to a source – meaning disastrous consequences for the planet. Monitoring of...

This study investigates the many dynamics of the Manyame Catchment and comes up with recommendations on how to adapt or become more resilient to the risks at hand. The bad politics and forthcoming economic situation of Zimbabwe has led to instability and dramatic inflation over the last decade. This has resulted in a terrible investment climate,...

In 2008 the Red Cross Red Crescent (RCRC) started with Forecast-based Financing pilots to improve existing Early-Warning Early Action systems. Forecast-based financing is a new methodology to prepare, deliver and respond in a more effective and efficient manner, based on hazard forecasts. Actions are triggered when a forecast exceeds a danger...

The scarcity of groundwater storage change data at the global scale hinders our ability to monitor groundwater resources effectively. In this study, we assimilate a state-of-the-art terrestrial water storage product derived from Gravity Recovery and Climate Experiment (GRACE) satellite observations into NASA's Catchment land surface model ...

European agriculture and water policies require accurate information on climate change impacts on available water resources. Water accounting, that is a standardized documentation of data on water resources, is a useful tool to provide this information. Pan-European data on climate impacts do not recognize local anthropogenic interventions in...

Understanding, characterizing, and predicting drought is vital for the reduction of its consequences. In the last few decades, many studies have moved drought analysis from the conventional lumped approach to a more spatiotemporal analysis. Two main developments have motivated this: one is global data availability and the other is the number of...

Drought is a recurrent extreme climate event that strongly affects every spectre of the natural environment and human lives (Madadgar andMoradkhani, 2014). There were numerous drought episodes recorded in MidwesternUSA, particularly in California. It has affected many aspects, including water shortages, groundwater overdraft, critically low...

Droughts are a serious threat to the planet. Especially in agriculture, the consequences are devastating leading to reduced yields or crop failure with further implications for economics, politics and society. Being able to monitor and predict agricultural droughts is an important step to reduce agricultural vulnerability and secure livelihoods....

The Upper Blue Nile (UBN) basin is less-explored in terms of drought studies as compared to other parts of Ethiopia and lacks a basin-specific drought monitoring system. This study compares six drought indices: Standardized Precipitation Index (SPI), Standardized Precipitation Evaporation Index (SPEI), Evapotranspiration Deficit Index (ETDI),...

Climate change with extreme hydrological conditions, such as drought and flood, bring new challenges to seepage behavior and the stability of earthfill dams. Taking a drought-stricken earthfill dam of China as an example, the influence of drought-flood cycles on dam seepage behavior is analyzed. This paper includes a clay sample laboratory...

Water scarcity and drought (WS-D) are growing concerns throughout Europe and especially in Southern Regions. This study focuses on agriculture on Sicily, Italy. It explores the way(s) European policies to tackle WS-D are actively performed by the actors in the Sicilian water and agricultural sectors, in order to uncover potential disparities...

The Amazon rainforest plays an important role in the global water and carbon cycle, and though it is predicted to continue drying in the future, the effect of drought remains uncertain. Developments in remote sensing missions now facilitate large-scale observations. The RapidScat scatterometer (K<sub>u</sub> band) mounted on the International...

Since the 1990th Sasol, a local Non-Governmental-Organization (NGO), builds sand storage dams, to mitigate the consequences of droughts in the semi-arid county of Kitui, Kenya. Sand storage dams are dams constructed in ephemeral rivers which increase the storage capacity of the riverbeds. The water stored by sand storage dams enables local...

The time lag between anomalies in precipitation and vegetation activity plays a critical role in early drought detection as agricultural droughts are caused by precipitation shortages. The aim of this study is to explore a new approach to estimate the time lag between a forcing (precipitation) and a response (NDVI) signal in the frequency...

Simulation of reservoir operations is important to investigate the effects of climate change and changes in human water demands on water availability in the future. Several reservoir simulation models exist, however it is unknown in which situations what type of model could be applied. This study tries to give an answer to the question how...

This book addresses pressing challenges of policy makers, planners and project managers in the water sector to successfully implement adaptation action. It draws on case studies about water sensitive urban design (WSUD) in Australia and the Room for the River flood protection programme in the Netherlands. The book explains a procedure for...

The fresh water supply will be more under pressure, due to the predicted effects of climate change in the Netherlands. More frequent salt water intrusion during the summer semester is caused by the joint occurrence of low river discharges and the expected sea level rise. The control of external salinity is necessary to guarantee a sufficient...

This research investigates the Wilnis dike failure that occurred in the dry summer of 2003. It is believed that drought played an important role in decreasing the stability of the dike, finally leading to failure. In the reported MSc project the situation during drought is simulated with the help of finite element method programs Plaxis and...

Transport van verontreinigingen via slibdeeltjes (vooral via gesuspendeerd materiaal, daarnaast ook via ‘bedload’) kan een belangrijk aandeel vormen in het totale transport van deze stoffen. Het kan hierbij gaan om grote hoeveelheden die bovendien grensoverschrijdend verplaatst worden, en grote ecologische effecten teweeg kunnen brengen. Voor...
