بررسی عملکرد سیستم و سازه‌های کنترل و پخش سیلاب ایستگاه‌های آبخوان‌داری و ارائه پیشنهادات اصلاحی در راستای افزایش بهره‌وری (بررسی موردی: ایستگاه قوشه دامغان)

Flood spreading research stations on aquifers with multi-purpose purposes were implemented in different regions of the country, which have noticeable differences in terms of climate, topography, land structure, geomorphology, soil and vegetation, with almost the same method. Considering the variety of structures and the possibility of evaluating their performance in the flood spreading stations on the aquifer of Semnan province, it has been tried to evaluate the basic points about improving the performance and increasing the life of the structures and suggest corrective solutions for it. The most important correction suggestions in the design of the system and structures are: 1- The correct location of the construction site of the flood distribution system based on geomorphological, hydrological, climatic and geological studies and in coordination with the departments implementing structural plans in pasture and desert areas. 2- Appropriate planning to control fine-grained sediments. 3- Restoration and modification of water supply channels - expansion and expansion using the construction of transverse walls in the area between flood transfer gates. 4- Study, investigation and precision in the placement of the gates according to the topographical condition of the broadcast arena. 5- Construction of a circulating slave system in order to control the flood speed, increase the length of the path, increase the permeability, sedimentation, control and direct the flood. 6- Vertical piping in the bottom of expansion channels to penetrate the flood to a depth of more than 4 meters after the flood accumulates in them and settles fine-grained sediments.
