The HGSRT Process

The HGSRT Process: construct a HydroGeoSphere model of your site

01

Construct a HydroGeoSphere Model of Your Site

Establish the geographical area where you’d like to perform near-real-time forecasting, and work with us to build a custom HydroGeoSphere model. Models typically range from site scale (<1 km²) at high resolution to coarsely resolved basins over 150,000km²).

The HGSRT Advantage

A physics-based approach is known to produce more accurate simulations even in regions with very little/sparse observational & borehole data. A custom-tailored model will resolve the features you care about and deliver insights your stakeholders need.

The HGSRT Process: Spin Up Your Model To Real-Time

02

Spin Up Your Model To Real-Time

Aquanty staff will spin your model up to near-real time conditions using meteorological (re)analysis data and short-term weather forecasts.

The HGSRT Advantage

Aquanty’s advanced weather and snow data processing pipelines mean your model will be marched forward in time with the best possible boundary flux data.

03

Gathers Real-time Data

HGSRT is connected to a wide range of data feeds, and more feeds can be added to the system. Data can be integrated from any available streamflow, groundwater, and soil moisture sensors.

The HGSRT Advantage

Near-real-time data feeds allow HGSRT to perform initialization, bias correction, predictive skill analysis, and to help provide context about changing conditions. Do you use Wiski, WSC, or USGS? We are already connected.

04

Forecast Initialization

HGSRT’s advanced forecasting pipeline will trigger forecasts at regular intervals. Forecast initial conditions are selected automatically based on observational data or from a continuous model spin-up that updates daily.

The HGSRT Advantage

HGSRT uses a patent-pending forecasting procedure. Complex data processing tasks are all abstracted away from the user for ease of use, and results are uploaded to the cloud for secure data dissemination.

The HGSRT Process: Automated Forecast Orchestration

05

Automated Forecast Orchestration

Hydrological forecasts are driven by liquid precipitation + snowmelt and potential evapotranspiration maps derived from a meteorological forecast. Postprocessing routines upload streamflow rates, water levels, and soil saturation predictions to the cloud.

The HGSRT Advantage

Weather forecast uncertainty is a major source of hydrological forecast uncertainty. By forcing the models with an ensemble of weather forecasts, the user can see a spread of possible conditions 7 to 32 days out.

The HGSRT Process: Visualize Results on Any Device

06

Visualize Results on Any Device

Use your desktop PC or mobile device to visualize forecasts using our advanced web map and time series charts. Export results for processing, or connect to HGSRT’s APIs. Securely lock down access to your own set of expert users.

The HGSRT Advantage

Integrated GW-SW models generate big data, but HGSRT’s web application is fast, modern, and responsive. Exported HGSRT forecasts can integrate seamlessly with your current computer systems.
