Abstract

In this study gravel filter were used to control runoff and sediment to enhance vegetation in Dareh Morid Basin of Baft, Kerman.This research was conducted in a completely randomized block design with four treatments and three replications.Treatments included natural system as a control, natural system with gravel filter, im permeable system without gravel filter, and impermeable system with gravel filter. The effect of gravel filter on reducing sediment and increasing vegetation was measured at depths of 25, 50 and 75 cm using TDR device after each rainfall.The results of this study revealed that at all three mentioned depths in the impermeable system with gravel filter, the moisture was significantly higher than in other treatments.The performance of the gravel filter along with making the system surface impermeable reduced sediment erosion and increased vegetation. As a result, it can be claimed that the rainwater harvesting through impermeable surfaces using gravel filter will be a good solution to control runoff plus sediment and a significant contribution to the water supply of plants in arid and semi-arid regions.
