The Problem<br />
The Problem illustrated in Figure 1 is based on the fact, that most of the existing drainage channels <strong>and</strong><br />
gullies are able to transport more than a certain discharge Qt without inundating the surrounding area. If the<br />
discharge overtops this threshold <strong>and</strong> reaches a peak discharge Q max, all resulting discharge (Qmax – Qt) is<br />
exceeding the drainage capacity of the transport channel <strong>and</strong> leads to flood water which cause inundation<br />
within the city.<br />

In order to adequately study the erosion <strong>and</strong> flood water processes <strong>and</strong> find appropriate solutions to the<br />
above research questions, the study team of 26 persons was subdivided into different groups. Each group had<br />
a specific research objective <strong>and</strong> members worked as a team both in the field as well as in generating a group<br />
report. Besides, each group gave a short presentation of their work after every two days. Below, is the<br />
summary of each group listed in chapter four.<br />
