Groundwater is the major source of drinking water and irrigation in many rural areas of India. In recent decades, groundwater abstraction using bore wells (also known as tube wells) from deeper aquifers increased manifold. Over-exploitation of groundwater and its depletion over the years have resulted in drastic fall in groundwater levels and drying-up of existing wells in many areas. Construction of farm ponds, percolation tanks, earthen dams and minor water harvesting structures are some measures to enable storage and direct use of water and contribute to recharging and augmenting groundwater.Full Text

Five sets of cylindrical drip emitters used for up to five years in the farmlands were scanned using micro-computed tomography. Around 54.46–94.52% of the total clogging material on the emitters was found on the active outlet areas that facilitate delivery of water by the emitters. Also, larger flocks of the clogging material were found on the outlet areas. Emitter geometric features, viz. width of flow path, dent angle and boundary curvature were observed to influence the extent of physical and chemical clogging. Any attempt to design an anti-clogging emitter may necessarily include optimization of active outlets.Keywords
