and to maintain it in 1337, the water and soil protection committee was formed in the country. dam management in iran, most of its goal in the early years was to reduce the input to the reservoirs of the country's dams. he found taking money and taking credit i started to build a structure and maintain a forest in the early fifties and it became operational in lavasan. it is the first fruit juice activity in the country in this area . it was done in figure 13. now there is one here that is covered with snow from the beginning of the projects until 1957, about 800 . a thousand watershed operations had been carried out in the country, and with the increase in activities , it has reached 3.6 million hectares, and it became a technique to solve water problems and needs and to strengthen financial resources, the slope of the watershed operation curve in the fourth and fifth periods of development is declining. however, our credit resources did not grow compared to the expenses during the development period, it had gained more speed when my mother did this. now , about 63% of the old

shirazi's report to protection soil and the dangers of soil erosion in iran, providing water and soil with vital elements that in order to preserve them, the water and soil protection committee was formed in the country in 1337. reservoir management in iran was mostly aimed at reducing the sediment entering the country's dam reservoirs in the early years. 1348, the first water catchment research was started in the country, and after injecting corton , i started to build structures and green leaves. in the early fifties, water catchment became operational. this catchment area of ​​letian dam in lavasan is the first fruit juice activity. it was done in this region in the country, but now there is one here it is known that since the beginning of the implementation of the projects in the year 1957, about 800,000 hectares of snow cover had been implemented in the country, and with the increase in activities , it has reached 3.6 million hectares. the watershed operations curve declined in the fourth and fifth period of development, our credit resources did not grow compared to the costs, but in the sixth period, the development speeded up, and it was because my mother did this now

iran's experts held a conference on soil protection and the dangers of soil erosion in iran, and the vital elements needed to preserve it in 1337, the water protection committee the soil was formed in the country. dams in iran mostly aimed to reduce the sediment entering the reservoirs of the country's dams . the structure and conduct of war that you have in the early fifties the operation of this catchment area of ​​the letian dam in lavasan is the first fruit juice activity in the country in this area , which was carried out in the form of sediment dams, and now there is one here, covering about 800,000 hectares of snow from the beginning of the projects until 2057. watershed management in the fifth country with the increase of activities has reached 3.6 million hectares and has become a technique to solve water problems and needs and strengthen the country's water resources . the costs did not grow, but in the sixth period, the development speed it took more time for my mother to do this. now, about 63% of the old people say that the importance of watershed management is that the instruments do two things . with the recent floods that have happened in the

and managers and a report on soil protection and the dangers of soil erosion in iran, giving water and soil vital elements that are necessary to maintain in 1337, the committee water and soil protection was formed in the country. water dams in iran were mostly aimed at reducing the sediment entering the country's dam reservoirs. water dam research was keyed in the country. and back, but in the early fifties, a water dam was put into operation. letian is in lavasan. the first fruit juice activity in the country was carried out in this area in the form of a series of sediment dams, and now there is one here . about 800 thousand hectares of tabrizi operation in the country has become the fifth it was said that with the increase of activities, it has reached 3.6 million hectares and became a technique to solve water problems and needs and strengthen the country's water resources. did not grow, but in the sixth period, the development speeded up until now , about 63% of the old experts say about the importance of watershed management, it takes one's instruments when it rains , when it comes, water gets inside the thing at this rate, and new experts on the country

management projects in 2017. soil and the dangers of soil erosion in iran and the vital elements to preserve it in 1337, the committee for water and soil protection was formed in the country, dam management in iran , most of its goal in the early years was to reduce the inflow into the reservoirs of the country's dams . the researches of abrizdar in the country got the key, he found it through a wedding card, took money and got credit, i started to build a structure and maintain a forest, which was operational in the early fifties, the abrizdar is in lavasan , the first fruit juice activity in the country was carried out in this area. the shape of a series of sedimentary bands is now it is known here that from the beginning of the implementation of the projects to the year 1957, about 800,000 hectares of watershed management operations were carried out in the country, and with the increase in activities , it has reached 3.6 million hectares and became a technique to solve water problems and needs. and strengthening the country's water resources, the slope of the curve of watershed operations declined in the fourth and fifth periods of development
