Abstract

Consumption of water as the main request is unavoidable in human life. Many areas of Iran, including Mazandaran, faced problems with access to water in necessity seasons. In wet areas with good annual rainfall, proper management of available water resources and rainwater harvesting is a worthy solution. The aim of this study is to analyze the long-term rainfall in Babolsar based on synoptic data in order to select areas prone to rainwater harvesting in the city. In this study, the time series of daily rainfall data in a period of 68 years including the years 1952-2012 has been used and the climatic parameter of precipitation in three periods of monthly, seasonal and annual has been analyzed. Analysis indicated the implementation of rainwater harvesting systems and areas prone to this in the city of Babolsar is approved. The results of this study showed that the Gamma operator with a coefficient of 0.7 is the best option for the study area. According to the calculations, the amount of runoff in the city was estimated at 696,570 cubic meters, which is very suitable for rainwater harvesting.
