Abstract:This research addresses the drainage capacity problem of the side channel of the Peursumse Vliet. The Peursumse Vliet is a polder drainage channel north of Giessenburg, in the Alblasserwaard, South-Holland. This research was done, in commission and in collaboration with Waterschap Rivierenland, which is the responsible water authority of the area. The aim of this research is to create and evaluate design scenarios with alternate solutions to increase the drainage capacity of the channels near the Peursumse Vliet without dredging. To achieve this aim, two scenarios with alternate solution and a reference scenario are created. However, the water system of the Alblasserwaard and the Peursumse Vliet are described first. And furthermore, the context and urgency of the problem are explained. After, alternate solutions for the problem are devised and two scenarios and a reference scenario are created. The reference scenario is a scenario with minimal measures, instead of making major adjustments to the area and water system, just maintaining the current situation and managing the current assets is the goal of this scenario. The first scenario (scenario 1) makes use of a temporary pumping station to drain water out of the polder. This way, less water has to flow through the concerned channel and therefore stress on those channels is relieved. The second scenario (scenario 2) adds a second channel alongside the Peursumse Vliet in order to increase the drainage capacity of the system. The goal of this measure is to release stress on the current channel and improve the drainage capacity without having to dredge. After the creation of the scenarios, the scenarios are evaluated following the stakeholder wishes using a multi-criteria analysis. Therefore, a stakeholder analysis is performed first. The main stakeholders are the different departments of Waterschap Rivierenland, neighbouring inhabitants, wildlife and the municipality. From these stakeholders, the following set of design criteria are chosen to evaluate the scenarios on: costs, time, durability, technicality and risks. The multi-criteria analysis gives scores to the different scenario’s based on the criteria and their respective weights. Concluding from the design evaluation, the second scenario with the additional channel is the most preferred. Using the weighting strategy, that best suits the goals of Waterschap Rivierenland and the Peursumse Vliet, which gives the second scenario has a MCDA score of 128 while the others have 119 and 120 respectively. In my opinion, the second scenario is indeed the most preferred solution, and the cost would be good value, mainly because of the long durability of the solution and the fact that a temporary bridging solution is able to continue into a permanent solution in the future.
