Learning objectives:<br />
The learning objective of the course is to give the students a fundamental knowledge and a pratical<br />
understanding of the common techniques for data processing in hydrology and water management. This<br />
knowledge and understanding must allow the students to select and apply most appropriate techniques to<br />
summarize and organize data. It also allows them to have an insight in the limitations of data collection, and the<br />
corresponding consequences for the water management. More specifically, the consequences to the<br />
development and the calibration of mathematical models and other predictive tools are discussed. Also the<br />
consequences to the evaluation, the exploitation and the management of the water systems are addressed. The<br />
latter water management and research tasks may be based on mathematical modelling or not. The understanding<br />
of the data limitations and their consequences are also useful in setting up most appropriate data collection<br />
programs for specific water management and planning problems. Based on discussions of the different<br />
uncertainty sources, also a fundamental insight is given in the general process of mathematical modelling. By<br />
using examples from specific water fields (surface hydrology, hydraulics, wastewater treatment, …) in the<br />
lectures and the pratical sessions, this course has an important interaction with the other courses.<br />
Course description:<br />
An overview is given of the important concepts of probability and statistics as they are used in hydrology and<br />
water management. After an introduction of the basic terminology, an overview is given of techniques for data<br />
handling and data processing. These techniques can be classified into two groups: descriptive statistics and<br />
inferential statistics. In descriptive statistics, most common techniques are considered for summarizing and<br />
organizing the data in a sample (a dataset). These consist of both numerical and graphical techniques. In<br />
inferential statistics, techniques are studied to draw conclusions about the physical reality (the full population),<br />
based on a limited amount of data available (a sample). Regarding the latter techniques, also the notion of<br />
mathematical modelling is explained together with the different sources of uncertainty involved. In this way,<br />
the students are given a basic understanding of the limitations of mathematical modelling and their<br />
consequences to water management and planning decisions.<br />
The course uses examples in theory as well as for the exercises. These examples are mainly hydrological and<br />
water quality data that are typically available for surface waters.<br />
The following topics are addressed in the course, in chronological order:<br />
1. Initial definitions:<br />
statistics, probability, hydrological variables, -series, -processes and -data;<br />
population vs. sample, errors in data<br />
2. Descriptive statistics:<br />
- Presentation of data:<br />
