Data usage

The data of the project can be downloaded for free. In the tab Overview and Download or here in the CrowdWater Menu, you have to click on “Download Project Data” and accept the license. At the moment, you will get an empty file when you download the data for the first time. If you repeat the process, you will get a file containing all the data.

The first two dissertations written within CrowdWater considered the category “virtual staffgauge”. Subjects of the research were the usability of the collected data for hydrological models as well as possible improvements with the CrowdWater game. The publications, easily understandable summaries and comics of the take home messages can be found here.

The data can be used by everyone for example for hydrological modelling. The different parameters of a hydrological model are calibrated on the basis of runoff, precipitation and temperature data of the past. Goal is for the model to represent the characteristics of a catchment as well as possible and to be able to simulate the runoff in the future. The runoff data can be collected in many ways, for example by measuring water level classes with the CrowdWater app and converting them into runoff data. The relation between waterlevel and runoff will differ for every individual spot.

Hydrological modelling is applied for example to develop flood warning systems, to regulate the water usage for agricultural purposes, to manage water resources in general or to plan on the energy production by hydropower plants. However, there are many other fields of use.

An example of a hydrological model is the HBV model which was developed in Sweden by Sten Bergström in the 1970s. The HBV light version by Jan Seibert is an improved version in terms of user-friendliness and can be downloaded here. More information can be found in these slides.

CrowdWater waterlevel spots which were updated regularly are suitable for the usage in hydrological modelling. However, all the CrowdWater data from all the categories can be used for other purposes too! We are looking forward to see applications of CrowdWater data in many fields of use.

We are happy if you write us a message to if you use the data, so we can see what can be achieved with it.
