Short summary
Short summary
Creep of soft soils such as clays and peat are important in settlement caused by surface loads. By contrast, creep is not commonly considered in land subsidence driven by groundwater pumping. This is odd, because the subsidence involves the same types of soft soils. A new MODFLOW-2005 land subsidence package is introduced that includes creep. In an application to northern Jakarta it is shown amongst others that creep contributes to subsidence long after drawdown in pumped aquifers has stabilized

A tool is presented that allows efficient and largely automated production of predictive land subsidence maps on a national scale in the Netherlands. The tool, based on Python scripts, is named Atlantis and calculates the subsidence induced by phreatic groundwater level management in Holocene soft-soil areas through peat oxidation and consolidation. Process formulation, input datasets and data handling procedures are elucidated. Maps produced with Atlantis will soon be available online.

Short summary
Drained peatlands cause high CO2 emissions. We assessed the effectiveness of subsurface water infiltration systems (WISs) in reducing CO2 emissions related to increases in water table depth (WTD) on 12 sites for up to 4 years. Results show WISs markedly reduced emissions by 2.1 t CO2-C ha-1 yr-1. The relationship between the amount of carbon above the WTD and CO2 emission was stronger than the relationship between WTD and emission. Long-term monitoring is crucial for accurate emission estimates.

Short summary
In general, water infiltration systems in peat meadows reduce groundwater level lowering and yearly vertical soil dynamics. Groundwater level fluctuations induce soil volume decreases and increases in both the saturated and unsaturated zone, causing yearly soil dynamics of up to 10 cm. Multi-year subsidence rates are in the order of mm/yr. Such research is vital to increase knowledge on subsidence processes and to develop effective measures to reduce land subsidence and greenhouse gas emission.

Short summary
Draining peat causes high CO2 emissions, and rewetting could potentially help solve this problem. In the dry year 2020 we measured that subsurface irrigation reduced CO2 emissions by 28 % and 83 % on two research sites. We modelled a peat parcel and found that the reduction depends on seepage and weather conditions and increases when using pressurized irrigation or maintaining high ditchwater levels. We found that soil temperature and moisture are suitable as indicators of peat CO2 emissions.

Levelling and extensometers are applied to monitor subsidence in a cultivated peatland in Overijssel, The Netherlands, in the period end 2018 to end 2019. Preliminary results show vertical movements in the order of centimeters related to seasonal dynamics (rise in autumn/winter, subsidence in spring/summer) and shorter-term dynamics related to groundwater level fluctuations. Additional data collection is needed to assess long term net subsidence.

Ongoing subsidence is a complex problem for the Netherlands. Old strategies for coping have limits. In the Dutch National Scientific Research Program on Land Subsidence (2020–2025), we will develop an integrative approach to achieve feasible, legitimate and sustainable solutions for managing the negative societal effects of land subsidence, connecting fundamental research on subsidence processes to socio-economic impact of subsidence and to governance and legal framework design.

For many subsiding coastal areas, solutions to subsidence are readily available, but difficult to implement. To facilitate decision making and implementation of measures to subsidence, a sound and shared knowlegde base is required. But how to start creating such a knowledge base? This paper presents a comprehensive, step-by-step approach to address land subsidence, illustrated by best practise examples from around the world. This 6M approach will contribute to lowering the threshold to act.

We present a framework to evaluate the benefits and costs of coastal adaptation through dikes to reduce future flood risk. If no adaptation takes place, we find that global coastal flood risk increases 150-fold by 2080, with sea-level rise contributing the most. Moreover, 15 countries account for 90 % of this increase; that adaptation shows high potential to cost-effectively reduce flood risk. The results will be integrated into the Aqueduct Global Flood Analyzer web tool.

Land subsidence is a global problem, but a global land subsidence map is not available yet. Such map is crucial to raise global awareness of land subsidence, as land subsidence causes extensive damage (probably in the order of billions of dollars annually). With the global land subsidence map relative sea level rise predictions may be improved, contributing to global flood risk calculations.

Short summary
In many coastal and delta cities land subsidence now exceeds absolute sea level rise up to a factor of ten. The total worldwide damage of resulting increased floodrisk and structural damage to structures is estimated at billions of dollars annually. In this study a quick-assessment of subsidence is performed on mega-cities. Results of these case studies are presented and compared, and a (generic) approach how to deal with subsidence in current and future subsidence-prone areas is provided.

Short summary
In many delta cities land subsidence exceeds absolute sea level rise up to a factor of ten by excessive groundwater extraction related to rapid urbanization and population growth. An Integrated Assessment Framework (IAF) for subsidence is introduced, illustrated by several (delta) case studies. Based on that a list of 10 generic key issues and possible solutions is presented in order to further develop and support a (generic) approach how to deal with subsidence in subsidence-prone areas.

Short summary
Minimizing land subsidence is of increasing importance in urban areas in The Netherlands. Modelling was done to shed light on various measures to control the water table in reducing land subsidence. Calculations were done for conditions that occur in the city of Gouda. Results suggest, amongst others, that measures that can more permanently raise the water table by a small amount are more effective than measures that prevention a large water table drop during an occasional drought.
