A tool to evaluate and optimize water management and climate adaptation strategies at the scale of an integrated water system
SCAN is a software that supports the evaluation of climate adaptation strategies. The tool can be used to analyze the integrated water system, while focusing primarily on water quantity - hydrology and hydraulics (rivers, floodplains and urban drainage systems incl. reservoirs, rain water tanks, infiltration devices, different types of blue-green solutions, effect of hydraulic regulations, etc).

Technology has been proven to work in its final form and under expected conditions. In almost all cases, this TRL represents the end of true system development. Examples include developmental test and evaluation (DT&E) of the system in its intended weapon system to determine if it meets design specifications.

Our technology is TRL 8: the concept and models underlying our SCAN system have been proven to work in several operational projects for end users. See: https://www.sumaqua.be/new-cases for an overview of these projects.
How does it work?
The proposed concept makes use of several highly innovative modelling approaches and building blocks, that flexibly can be combined to build a tool for decision support on integrated water systems, which may consist of catchments and/or rivers, sewer systems, etc (both large and small scale systems). The modelling approaches are flexible and modular, such that we can create tools tailored to the intended applications. Also, the level of model detail is adaptable, thereby obviating the creation of overly complex and too rigid models. Different temporal and spatial scales can be covered.
Due to their flexibility and very short calculation times, the created models are ideally suited for various applications requiring numerous or long term simulations, and integrated analyses, such as simulations of the effect of climate scenarios, land use changes, water management scenarios; real-time applications, including intelligent real-time control and warning systems; evaluation and optimization strategies: from the installation of blue-green solutions, retention and infiltration basins along rivers and sewer systems, to strategies to optimize the water availability at catchment or regional scale, to integrated flood - drought control strategies, hydropower, etc. The tool can account for uncertainties and probabilistic analyses through ensemble runs.

GM4W - GeoGuard Module for Water vapor monitoring
Monitoring the temporal and spatial variability of precipitable water vapour (PWV) at a local scale is important to improve the probabilistic nowcasting and forecasting of localized sudden storms and heavy rain, that can have spatial scales down to few kilometres. Local fluctuations of PWV, in fact, may be associated with increases of water vapour in the lower troposphere, which cause deep convection that may result in heavy rainfall. Before the initiation of convection, convergence of water vapour near the ground surface occurs. Previous studies reported that the local-scale amount of water vapour at a height of 1 km increases from about 30 minutes to 1 hour before the formation of rain drops because of the ground surface convergence process. This local-scale signal can be a precursor of rainfall, which would be useful to be assimilated into numerical weather prediction models, thus it is deemed important to detect it by high-resolution PWV measurements.
GM4W provides new technology for the reliable and continuous water vapour monitoring with high horizontal resolution. It is based on low-cost single-frequency Global Navigation Satellite Systems (GNSS) receivers, designed and developed by GReD through a collaboration with Proteco Consortium. They can also be used to detect the deformation and movements of the ground (e.g. landslides, subsidence) and critical infrastructure (e.g. dams, bridges, high voltage towers, etc) and are designed to be able to operate under all weather conditions.

We should actually consider two different TRLs:
- the hardware (i.e. the monitoring units which will be deployed on the field) is at TRL 9, since the same GNSS units have been used by large clients of GReD for critical infrastructure (i.e. bridges, dams, high-voltage towers) and land (i.e. landslides) displacement monitoring for more than 1 year.
- the overall water vapour monitoring system, which includes innovative (server-side) components such as the local ionospheric delay modelling and the continuous estimation of tropospheric delays, from which the integrated amount of precipitable water vapour can be inferred. This is more likely at TRL 6, since the technology has been demonstrated in relevant environment, namely by dedicated dense networks deployed for testing; however, it was not demonstrated in an actual operational environment, where water vapor data would have to be analysed for probabilistic nowcasting in order to issue timely early warnings.
How does it work?
GM4W uses low-cost single-frequency GNSS receivers (basically the same chipsets that are used within smartphones and car navigation systems) to retrieve Precipitable Water Vapour (PWV) after compensanting single-frequencies measurements for the ionosphere-induced delay estimated by local ionospheric models. These models, which are used with a dense network of low-cost receivers, can be estimated by a Precise Point Positioning adjustment of the observed pseudo-ranges between a receiver and all the satellite in view at a given epoch. GM4W technology consists of IP67-certified weather-proof monitoring units that are able to exploit low-cost GNSS data for the estimation of PWV.

Water from Heaven - Hemel(s)water
Water from Heaven contributes to local rain water storage and helps to overcome droughts.
Drinking water made of rain from own roof. Sustainable water purification and storage for dry seasons.

Two prototpes are tested at different environments:
1) A first pilot was installed at Ecovillage Boekel in February 2016 and is still running
2) A second pilot was performed at Heijmans One (a mobile house). Heavenly water together with the Tesla power wall made this house utility independent.
How does it work?
Water is collected from the roof and stored in a storm water collection tank (large enough to collect extreme rainfall) then by gravity the water is purified by an ultra filtration membrane system that removes bacteria and viruses. The water is stored in a pure water tank, large enough to overcome droughts. An optional pump allows water flows in house for showering etc.
