A long-time water-table study of an irrigation project in Southern Alberta

Authors: Rapp, E. And J.C. Van Schaik
Description: Adequate crop production in irrigated areas generally requires water-table depths of at least 152 cm (2). Although crop production in arid and semiarid areas is possible with water tables at shallower depths, the danger of water logging and salinizing of the surface soil can be reduced by proper irrigation management, or by installing adequate sub surface drainage. In many irrigation districts observation wells are used by project personnel to detect areas where sustained crop production is endangered by water tables rising too close to the surface. Rapp and van Schaik (4) studied short time records of some observation wells on the Bow River irrigation project to deter mine cyclic trends of water tables in glacial till soils during several growing seasons. However, short-time records do not permit estimation of long-time trends as affected by hydrologic cycles and changes in irrigation practices. Rapp et al (3) studied the relationships between irrigation water use and various hydrologic budget items from 1958 to 1968, inclusive, for the Vauxhall District of the Bow River Project. The objective of this study was to determine long-time trends of water-table depths in the Vauxhall District of the Bow River Project in Alberta, Canada.
