| Abstract: | The aim of this research is to gain a clear image of two recently introduced methods, the entry test and trajectory approach, in dike reinforcement preparation that can be used by waterboards to apply for the program list of the HWBP. Besides, the consequences of these two methods on a project of Waterboard Rivierenland are examined. 6 experts from various waterboards have been interviewed that have experience with at least one of the two methods, or both. From their experiences a benchmark analysis was conducted with the goal to compare the methods to each other. Considered quantitative benchmarks are lead time, time investment, amount of employees and (extra) financial cost. Most experts indicated a relatively small lead time (compared to the total assessment chain) and also indicated a parallel execution of tasks, leading to a small time investment. The amount of employees is comparable to a normal project team and the two methods do barely have any extra financial costs. Qualitative benchmarks are ease of use, administrative goals & ambitions and preparation. These benchmarks are scored on a scale based on expert experiences. The results are dependent on a lot of factors and include subjective judgement and should therefore be taken with caution. From these results possible consequences regarding planning for a project from Waterboard Rivierenland, Sprok-Sterreschans-Heteren (SSH), have been determined. Three options of method implementation on the SSH timeline are given as well as advice for the continuation of the SSH project regarding the use of the entry test, trajectory approach or both. It became clear that the entry test is a structured method that helps identify uncertainties, area partners and linkage opportunities early on in the dike assessment chain, and helps give projects an accelerated start towards a (pre-)exploration phase. Useful advice and tips for the continuation of projects are given by the assessment team of the entry test, resulting in more stable project scopes. The trajectory approach is a useful non-obligatory tool that helps defining a reinforcement strategy considering the area characteristics, uncertainties and planning of area partners. The implementation of the trajectory approach differs much per waterboard and is very dependent on specific characteristics of the dike reinforcement project and priorities of the waterboard. It is up to the waterboard how to integrate the trajectory approach together with the entry test, which could result in a considerably lead time. |
