WARREDOC International Winter School on Data Rich Hydrology 2019

The "Data Rich Hydrology" Winter School 2019 took place in beautiful Colombella, Perugia (Italy). It was jointly organised by the Water Resources Research and Documentation Center (WARREDOC) and UNESCO World Water Assessment Program (WWAP). The WARREDOC was established at the Università per Stranieri di Perugia (UNISTRAPG) since 1985 - developing research, advanced training and scientific communication in the field of water, environment and disaster risk management.

The days were organised into a serious of lectures and lab sessions and food and accommodation were provided all at the location of the Villa Colombella, that was an extraordinary experience. We were completely immersed in this place students and lecturers altogether.

The program encompassed mainly lectures of absolute high scientific standard and well presented by the experienced and well-known lecturers.

- The Era of Data Rich Hydrology, 1st keynote lecture, by Prof. Rafael L. Bras

Prof. Bras is one of the forefathers of hydrology (Google Scholar). He gave us a history lesson of conceptual, numerical and later computational hydrology and modelling of catchments. He concluded with the outlook of what we as young hydrologists should keep striving towards to improve understanding and modelling of the hydrological cycle.

- The WWDR and SDG 6 Synthesis Report, 2nd keynote lecture, by Prof. Stefan Uhlenbrook, also head of UNESCO WWAP

- Remote sensing and data assimilation in hydrology by Prof. Fabio Castelli

- Hydrologic modelling in a data rich world by Prof. Prof Riccardo Rigon

- Citizen science and big data in hydrology by Prof. Fernando Nardi

- Beyond traditional extreme value theory: lessons learned from rainfall and hurricane intensity by Prof. Marco Marani

More topics got covered by further renowned professors, researchers and practitioners in hydrological and hydraulic modelling:

- Groundwater hydrology and hydrological process mechanics
- The water-food-energy nexus
- Modelling scaling properties of precipitation fields
- Hydrologic measurements and novel observation technologies
- Drones in Hydrology (lecture & hands on)
- Hydrological risk assessment: Return period and probability of failure
- Advances in the space-time analysis of rainfall extremes
- Data poor vs. data rich cases for flood hazard (lecture & hands on)
- Distributed Data quality and urban flood modelling uncertainty
- Stream flow measurements: ground and satellite observations
- Remote sensing data and tools to foster inland water monitoring and flood modeling

I also had the pleasure to get interviewed by research fellow and PhD student Francisco Pena, who does a radio show on Disaster Risk Reduction. We had a great chat about our ideas and views on the topics and lectures during this Winter School on Hydrology and did some brainstorming:

Hydrological Society Conference - Web-based real-time processing of environmental measurements

This case study was presented as poster abstract.

Kmoch, A., White, P. A., & Klug, H. (2015). Sensor Observation Service and web-based real-time Processing of environmental Measurements in the Upper Rangitaiki Catchment (Poster). In The NZ Hydrological Society Conference 2015, 26th November, in Hamilton, New Zealand

Abstract:

Environmental assessments naturally depend on field observations and technological advancements. , such as tTelemetry, allow the automated collection, transmission and processing of these measurements. However, modelling of natural processes is typically a complex challenge and involves applying expertise of scientists as well as a host of data preparation steps (White, 2006, White et al., 2003).
In addition, automation of model execution with the most recent observation data is dependent on the integration of the data collection, storage and processing elements (Klug and Kmoch, 2014). This paper demonstrates a system that integrates a Sensor Observation Service (SOS) that includinges field observations and internet-based environmental data with a rainfall recharge model that allows near-real time calculation of rainfall recharge in the Upper Rangitaiki catchment, Bay of Plenty region.
The SOS specification is an Open Geospatial Consortium (OGC) standard for the open and standardised integration of environmental sensors into an internet-based environmental data infrastructure (Klug and Kmoch, 2015, Klug, Kmoch, Reichel, 2015).

Figure 1. Process of data flow from field site sensors, to SOS data service to a simulation model process

Results:

• We showed that it is possible to link the collected data directly to a simple rainfall recharge model (Figure 1)
• The low cost sensor and circuit board instrumentation collects data and forwards them to the field computer in 10-minute intervals via robust, low power, ZigBee wireless protocol
• The field computer running a standard Linux operating system, transfers observation data in 10 minute intervals via a 3G mobile data connection to an online SOS server.
• From the service the observations are available in a standardised open format.
• A website can access the raw data from the SOS server and plotted data points within 5-10 minutes of field measurement
• A rainfall recharge model runs with the latest data points from the online SOS server.
