  Performance assessment (PA) of irrigation and drainage systems has been an important area of research and debate in recent years. The present study was carried out to determine some performance parameters of sprinkler irrigation systems. Thirty-eight subunits (lateral) were monitored and assessed in the Konya Basin of Turkey. Sprinkler nozzle-pressure, flow rate, and their variations, and the amount of irrigation water were determined. Application and distribution uniformity, irrigation adequacy, and characteristics of system design and application were analyzed. Christensen Uniformity coefficient (CUC) and distribution uniformity (DU) values were between 41% and 88%, and between 18% and 81%, respectively. Variation in pressure and flow rates, and the use of different sprinkler parts in the same system were the main causes of the observed heterogeneity. It was concluded that by reducing lateral spacing the water distribution pattern, such as CUC and DU, could improve significantly and thus improve irrigation adequacy.

  Soil salinity and water logging, as well as water scarcity, are the most common problems limiting irrigated agriculture crop production in southeast Turkey. Thus, this study was conducted in order to predict the effect of drainage control factors on irrigation efficiency, irrigation sufficiency, root zone salinity, and drain discharge using SaltMod simulation. Investigations were conducted in the Harran Plain, also known as the Fertile Crescent or Upper Mesopotamia. High crop evapotranspiration rates and deep water table levels have led to visible increases in irrigation water requirements in the region. Therefore, the level of the water table appears to be a factor of great importance to sustainable crop production. Root zone salinity will increase to 3.0 dS m-1 at the end of a 10-year period if the drainage control factor (Frd) increases to above 0.75; however, the drain discharge rate was estimated to decrease from 1.350 m to 0.050 m for the summer season and to increase to 0.026 m in the winter season. In contrast, total drainage is predicted to decrease while irrigation efficiency is forecasted to increase during the summer season.
