The increase of world population requires food security and sustainable agriculture and these achievements can be reached through drainage of agricultural lands. The conventional drainage methods such as lateral drainage, vertical drainage and interceptor drains have been used for many years to control water table and soil salinity. These methods increase agricultural production but their installations are expensive and cause damage to environment. Therefore, in recent years, less expensive and more environmentally acceptable drainage methods have been introduced. Dry drainage is a new drainage method that has been introduced recently. In this method, the natural soil system is used to reclamate soil and evaporation of fallow land is used to control soil salinity and water table of planted area. In dry drainage, part of field will be cultivated and another part will be left as fallow. For dry drainage it is required that the water table be shallow and evaporation be high similar to the condition of many dry and semi dry regions. There are few researches about the design and performance of this method of drainage under different soil salinity conditions. Therefore, the objective of this study was to evaluate the performance of dry drainage under different soil and irrigation water salinities. In order to simulate the conditions of dry drainage a physical based model with dimension of 200 cm length, 50 cm wide and 100 cm high was designed, constructed and the model was used to collect data. The model was designed in such a way that half of it could be used for irrigation and the other half could remain as fallow. The model was studied for six different combinations of soil salinity, irrigation water salinity and water table position. During each experiment and for each of the above conditions, soil moisture, soil salinity and temperature profiles were monitored, with respect to time and were compared. For each of the above conditions and during the experiment, the evaporation was measured. The lowest evaporation with value of 5 mm per day was observed at time that surface of fallow soil was covered with salt. This value is close to the common design value of drainage coefficient of agricultural lands. The results showed that as the irrigation water salinity increases the performance of dry drainage improve. As the salinity of irrigation water and soil increased, the daily evaporation decreased. For each of the experimental conditions, the salinity-evaporation profile was plotted. This plot can be used for better evaluation and design of dry drainage for the study site. For dry and semi dry regions, which are suitable for dry drainage condition, the use of dry drainage method is recommended to control and reduce soil salinity.
