Abstract
Water logging adversely affected agricultural lands creating doubts about the sustainability of irrigated agriculture. Many irrigation project command areas of Tamil Nadu lack adequate supply of water to agriculture in three to four months every year due to inadequate water resources. At the same time water logging problems due to excess water release from reservoirs during heavy rainfall periods from inter-state rivers is the common problem in some low lying areas. Hence a dual system to tackle water logging in monsoon season and scarcity during summer is the need of the hour. Water table management system (i.e. Controlled Drainage cum Sub irrigation system) is the next level of improving water management in irrigated agriculture. The water table management system was designed to work effectively both in monsoon season as controlled drainage system and as sub irrigation system during summer.
