Hydrology data and workflows

Quality-controlled and efficient access to hydrological data.

Data is integrated, stored and processed in trusted technologies

Online hydrology monitoring requires expertise blended with flexible thinking to produce precise, bespoke solutions to make the most of vital water resources data. ADASA has more than 30 years’ experience in selecting optimum technologies for hydrology data and workflows.

We know the market and solutions available and adapt them to guarantee solutions to fit water resources data requirements of our customers.

Real-time data acquisition, importation and integration are available via a wide range of water quantity and quality sensors, including IoT devices, telemetry and SCADA systems as well as data exchange formats. Apply automatic or manual quality control and assurance processes to make data more trustable and defensible.

Validate and clean incoming hydrologic data feeds with automatic or semi-automatic data quality assurance (QA) and quality control (QC) processes. There are toolsets to adjust and correct hydrologic data, including sensor drift and offset correction, threshold correction, gap interpolation and more. The system keeps all data versions, so all changes are audited.

Automated responses to real-time events remove the need for constant system supervisions. Our systems monitor all hydrological data to assess and respond to episodes, and can send early warning SMS or email alarms and notifications. Environmental compliance can be tracked, as well. This reduces the negative impacts of incidents as well as saves time.

Useful maps, data grids and charts give access to and display all available hydrological data to permit quick analysis and better decision-making.

There are pre-defined reports, too, ideal for periodic reporting and compliance, but also fully dynamic hydrologic data search engines. Data can be extracted in multiple text formats or made available through secured or published APIs should information be required by external consumers or third-party systems.

Online hydrology monitoring offers flexible and powerful calculation engines which derive data from raw observations, including aggregations, mixing data from different sources or applying stage-discharge or level-volume transformations and so forth. Modelling techniques and the use of machine learning can help our customers predict the status of valuable water resources and to define scenarios for impact assessment, dam release impact assessments, dam inflows or streamflow forecasting and more.

All hydrological data is always secured, with full control over user permissions and access. We use the latest technologies to ensure our customers they never lose access to their information. The system processing capacity can scale to adapt to storage or access needs, always mindful of the lowest infrastructure costs. ADASA offers the best quality and trustworthy solutions for hydrology data and workflows.
