1 Smedema, L. K.. 1988. Watertable control indices for drainage of agricultural land in humid climates. Agricultural Water Management, 14(1-4):69-77.
(Location: IWMI-HQ Call no: PER Record No: H05222)
Annual and seasonal watertable regimes of agricultural land have in many cases successfully been related to drainage objectives characterizing these regimes by such indices as average watertable depths, duration and frequencies of occurrence of high watertables, etc. The merits and applicability of these indices have been analyzed in this paper.
