& WaterITech

richland_chambers.jpg
Background

The Richland-Chambers reservoir was first impounded in 1987, and now serves as a key drinking water reservoir in Texas that, like many other reservoirs, faces serious eutrophication problems.

Challenge

Nutrient rich reservoirs often experience frequent blooms of potentially toxin-producing cyanobacteria and also periods of bottom water anoxia. Periods of anoxia can lead to increased levels of manganese in the water, which can cause problems with memory, attention, and motor skills in both children and adults, when used for drinking water over long periods of time.

Solution

ASAP Rural, ASAP Reservoir and ASAP Live are combined into an integrated digital twin and forecasting solution for the Richland-Chambers reservoir and its watershed.

Benefits

Forecasts of the hydrology and water quality of the Richland-Chambers reservoir can improve decision making in relation to reservoir operations, and facilitate reduced risk of downstream flooding as well as a more stable and cost-efficient water supply.

vejle.jpg
Background

The city of Vejle in Denmark is an area prone to flooding due to its topography. Vejle is therefore used as a test site for improving flood forecasting as part of the National Center for Climate Research hosted by the Danish Meteorological Institute (DMI).

Challenge

The Grejs and Vejle rivers join close to the city center, and due to their steep topography, they oftentimes experience overbank flooding shortly after cloud burst events. This means that historical and culturally important buildings in the city center are at risk, and that irreversible damage at times is caused by flooding events.

Solution

ASAP Rural has been set up, and further developed in collaboration with the core developers at US Department of Agriculture, WaterITech and DMI. Subdaily forecasts of river discharges are produced, and a range of experiments with the scale of weather forecast inputs to the hydrological model are done to improve flood forecast skill.

Benefits

ASAP Rural simulates hydrological forecasts, and provides a unique early warning and planning system. The municipality of Vejle now has the option to make decisions based on the forecasted risk of flooding, and for example operate a lock system installed in the Grejs river.
