Irrigation and Irrigation Canals in the Khorasan (8-10th Centuries)

In a medieval economic life based on agriculture, climate was an important factor affecting agricultural production. Although dry agriculture could be practiced in several places, water was an important element in conducting agriculture in a more efficient way. In Khorasan, a region rich in water resources, there was, however, a need for irrigation canals; and several projects were implemented to solve problems in irrigation water use during the period under study. For this reason, the canals were opened in a large part of the Khorasan. In this regard, the study discusses water resources, their distribution, streams, rivers, irrigation canals, irrigation practices and water use rights
