The PEARL institutional ABM simulating authorities' decision making for the selection of resilience strategies
Introduction
The local authorities that are responsible for the city’s flood protection are required to decide which measures are going to be implemented in their area of responsibility. The authorities are presented with a set of measures that are applicable to their area.
Each flood resilience measure may be characterised using different attributes and their alternative characteristics.
For example, as seen in the following descriptive table of a measure, the flood control dam is a long term engineering measure, built to protect downstream areas. It is mainly constructed to detain and store water and to increase the infiltration of water to the ground. It aims to mitigate the effects of flood events. Additionally, it has strongly positive impacts for pluvial, drainage and fluvial flood events and it is implemented on a river basin scale mainly in areas with rural land uses.
| Name of Measure | Flood control dam | ||
|---|---|---|---|
| Measure Type | Engineering | ||
| Measure timescale | Long term | ||
| Measure Type Approaches | Protection Approaches | ||
| Measure subcategory | Water Retention or Detention | Conveyance & Storage Structures | Infiltration & Buffering Technique |
| Application Target | Mitigation | ||
| Problem Type (positive effects) | Pluvial | Fluvial | Drain & Sewer |
| Spatial Scale | River Basin | ||
| Land Use | Rural | ||
Additionally, flood resilience measures require specific information related to the area of implementation, such as: the construction cost, the estimation of the construction/implementation time, the operational cost and the responsible authority. For example, the flood control dam that was built in Kamaraki basin that is described in PEARL’s Knowledge Base was built in 12 months, with around 1 million euros, needs roughly 5000 Euros/year as an operational and maintenance cost and is under the jurisdiction of the Regional Authority. Another flood control dam on another stream of Rethymno was built in 8 months, with around 500.000 million euros, needs roughly 2000 Euros/year as an operational and maintenance cost and is under the jurisdiction of the Municipal Authority.
Select Measures
In the following sections you may choose the set of flood resilience measures that will be included in the institutional simulation. You may choose to use the flood resilience measures that have been chosen for the Rethymnon region or you may choose to select measures from the PEARL’s Knowledge Base and define based on your expert knowledge the specific information related to the area of implementation.
