Abstract
Looming water scarcity could be curtailed with intelligent water losses control. Present study was designed to assess the relative effect of watercourse lining in prospect of seepage minimization. Qualitative as well as quantitative analysis was undertaken using water conveyance efficiency, annual water saving, increase in cropping intensities, time and land saving along with labor saving indictors over Gadeji minor in Sindh, Pakistan. Primary data was collected from field measurements while secondary data was gathered from NPIW (National Program for Improvement of Watercourses), Irrigation Department, personal interviews and site survey. The analysis revealed that lining of 30% initial portion of watercourses resulted average annual water saving of 10.32 hectare-m. Similarly, the cropping intensity increased 15% in Rabi and 14% in Kharif seasons. Crop yield increased by 17% for wheat crop, 14% for cottoncrop, 12% for sugarcane, 17% for chilies, 11% for onion crop and 20% for rice crop after lining the selected watercourses. Thus, it is concluded that watercourse lining has noticeable effect for seepage control which yielded a significant water saving. In future, economic viability of watercourse lining may be assessed for obtaining optimum benefits.
