The challenge is focused on the improvement of current version of system designed in first hackatho and further works. This system is calculating the water reservoir storage capacity based on the DEM of reservoir bottom and current water level with the incorporating the water reservoir watershed parameters and precipitation forecast. The input data are processed and stored in existing WebGIS server platforms (GeoServer, PostGIS).

Current system description:

• input data: Reservoir bottom DEM, Reservoir watershed DEM, land cover of watershed; data is stored in PostGIS
• database of water level simulations (substitution for actual sensors)
• database of soil moisture simulations (substitution for actual sensors)
• connection to openweathermap to provide the weather forecast data

What we expect from participants during the hackathon:

• general insight on the created system, discussion, proposals of improvement, new functionality
• creation of the of the hydrological modelling – new or existing models implementation and improvement in accordance to available data
• new or improved data inputs – weather forecast, soil maps, land cover, etc.

Introduction/Context

As the farmers are pumping out the water from reservoir, the water storage is decreasing and the water level is descending. The water level elevation can be surveyed with existing prototype of ultrasonic sensor that stores the currently measured and calculated water level elevation in database and with the use of reservoir DEM we can calculate the current amount of water in reservoir.

As the longer periods of droughts are presumed worldwide (climate change in progress), the amount of available irrigation water is crucial. If we would be able to incorporate the data from watershed (watershed terrain slopes, land use, soil types, etc.) and the prediction of precipitation (weather forecast), we can predict the amount of water that will flow to reservoir during drought period and during/after rain event. This would help the farmer to manage the usage of remaining water amount in reservoir by altering the uptake of water for irrigation.

Ambition of the challenge

Challenge is aiming both on introducing the concept to the broader audience of experts both to gain the new insight to this topic and to spread the concepts idea to incorporate its principles and solutions to the further incorporating in research topics and/or in practical applications in real situations.

Next steps

• spread the information
• gather the information to improve the system (technical, general)
• provide the opportunity to test the own solutions of hydrological modelling

Tools and applications:

• system i currently working on infrastructure of virtual server of company ATAPEX (PostGIS database, Geoserver, Python server), the sensors of soil moisture are operated by company PlantControl, weather forecast is provided by openweathermap. Org API

Used data:

• Reservoir bottom DEM, Reservoir watershed DEM, land cover of watershed; data is stored in PostGIS
• database of water level simulations (substitution for actual sensors)
• database of soil moisture simulations (substitution for actual sensors)
• connection to openweathermap to provide the weather forecast data
