ارزیابی مهمترین روش‏های سنتی و آبخیزداری استحصال رواناب در منطقه زاگرس

There are valuable Iranian farmer’s innovations in the field of water and soil resources which contribute to sustainable water usage and soil protection. The purpose of this research was to identify the technical characteristics of traditional methods of collecting and extracting runoff as well as modern watershed management methods in Zagros regions. For this purpose, six traditional methods that play a role in water resource management and storage and 11 watershed management methods were constructed mainly by the watershed management (affiliated to the former Ministry of Jihad-e-Sazandeghi). The evaluation consisted of two parts: technical evaluation (based on field verification by relevant expert) and local inhabitant comments. The opinions of the local farmers were mostly qualitative focusing on reception willing, taking similar measure and the resulting benefits. The results of this research revealed that most of the investigated measures play a effective role in harvesting rainwater and runoff, soil moisture storage, reducing soil erosion and flooding hazards. They were still common and had more points in scoring by responders. Furthermore, watershed management measures include short earthen dams, various types of stone dams built in the form of a cross section inside the waterway (check dam and gabion), river banks dike and terraces. Field verification showed that some of them were destroyed and partly eliminated. In general, all methods play a significant role in runoff harvesting and soil conservation, while the proper replacements are needed.
