Assessing the Problems and Increasing the Resilience of Madi in Isfahan against Urban Floods (A Case Study: Zones 1 and 3)

Water streams branching from Zayandehrood in Isfahan, called Madi, are unique features of this city. Madi play a vital role in climate, agriculture, groundwater recharge, and urban flood control in Isfahan. The purpose of this study is to evaluate the madi problems of areas 1 and 3 of Isfahan in order to increase their resilience to urban floods. In this research, using the method of survey and field surveys, the madi path of Isfahan city in the central areas of the city (regions 1 and 3) was investigated and the problems that arose for the madi in different places using the positioning device. Satellite finder and receipt-recording were recorded, then problems were identified and categorized and necessary management solutions were provided to solve problems. The results showed that the length of the madi network of region one is 10921 meters (10.9 km) and the madi of Niasaram spring with 3624 meters is the longest madi of this region. Zone 3, despite having a larger area than Zone One, has less material network than Zone One. Studies on the madi problems of these two areas showed that the madi of region one have 33 types of problems, the most important of which are bed slope correction and cleaning. There are 18 problems in area three, the most important of which is dredging and cleaning. For this purpose, solutions appropriate to the problems of each madi should be considered. Organizing the green space around the madi and proper use of urban furniture and creating a space in order to benefit and use as many residents as possible around the madi is one of the most important management strategies to maintain and organize the material network in these two areas.
