Abstract

In-Site water harvesting is just one of the rainwater harvesting techniques with a wide range of traditional and innovative methods. Its efficiency can be improved by applying proper management and mechanization. By following the traditional architecture of Iran and modifying the existing rainwater harvesting methods, designed an In-Site water harvesting system for planting or groundwater feeding, called the Kajaveh, as a matrix of inverted cones. In order to study the influential factors on the Kajaveh system, 13 different treatments were examined. The results indicate that there is a specific base diameter and cone height which were determined according to the climatic and geographical conditions of the region and lead to the optimal operation of the Kajaveh system in water harvesting. Considering the different initial conditions for these treatments, results indicated that the case with a wall slope of 0.3 m/m, cone base diameter of 50 cm, loam soil, rainfall intensity of 12 cm/h, and rainfall length of 10 min, to yield the best rainwater harvesting results and on the average provided 14.9% more water than the unstructured state in the target area.
