Notable people Amir Arsalan Motahari Jalil Zandi Ali Sorena Agricultural sector The Hablehrood river originating from Dalichai-Firouzkooh flows to the plateau of Garmsar. Its water is extensively used for agriculture. Since salt water mixes with Hablehrood before its arrival to the city, the water is not fit for drinking. Hablehrood is the only permanent river in Semnan province. Thanks to the water provided by Hablehrood, people in Garmsar grow wheat, barley, cotton and yellow melon. Garmsar is known across Iran for its sweet and crispy yellow melons. Water management The many river branches and the irrigated fields provide recharge to the aquifer. Since ancient times, groundwater in the Garmsar area has been exploited by ghanats (qanats, karezes) and shallow wells, mainly for irrigation of agricultural land, but also for household purposes. In the last decades, the number of deep-wells has increased sharply and the ghanats have fallen dry. Yet, at the fringes of the fan, problems of waterlogging occur owing to irrigation losses higher up that are transported through the aquifer to the lower lying areas causing shallow watertables, while the evaporation from the shallow watertable brings salts into the rootzone which henceforth is salinizing. As a result, the agriculture in the fringes suffers low yields or is impossible. Cuisine The traditional cuisine of the city is called Tahchin. It differs from the classic Tahchin common in other cities. Tahchin is a tasty and fragrant rice-based food where marinated raw meat is slowly cooked
