Bachelor thesis Evaluation of the results of intersucho.cz by external reporters analyses data from an online questionnaire available on intersucho.cz, where external reporters subjectively assess by marks whether the water balance in the soil according to the SoilClim model corresponds with reality in their region - district. The comparison of the districts was made on the basis of established criteria - for districts with more than 100 assessments per year, the objectivity coefficient is calculated by which the 4 worst- performing and the 4 best-performing districts are selected on the basis of the annual evaluation. The development of the assessment is analysed in more detail in selected districts. Based on the analyses performed, no demonstrable change in the assessment of model outputs by external reporters has been observed since the introduction of the new version of the water balance model SoilClim II. However, the overall improvement in the assessment in the previous year, 2021, which is the best-performing year since the introduction of the questionnaire investigation, is demonstrable.

The methodology describes how to predict soil moisture and drought intensity, and at the same time addresses reliability of the predictions and how these can be used. The ability to predict soil moisture values over a period of up to 9 days is presented through using ensemble of models for numerical weather forecasts. This method brings also new opportunities to mitigate impacts during drought events by farmers using such forecasting tools. With regard to the relatively high predictability of soil moisture and drought intensity, the methodology introduces the basic procedures and provides necessary information for the users. In this methodology, the results of 2017 drought event are presented as an example. The drought forecasting system for the Czech Republic is fully functional and is and will be available through www.intersucho.cz.
