Performance of the FAO AquaCrop model for wheat grain yield and soil moisture simulation in Western Canada

Mkhabela, Manasah S.; Bullock, Paul R. - In: Agricultural Water Management 110 (2012) C, pp. 16-24

Wheat (Triticum aestivum L.) is the major grain crop grown in western Canada (Canadian Prairies) and soil water stress is considered the main limiting factor for crop growth. The objective of this study was to adapt and test the ability of the FAO developed AquaCrop model (v3.0) to simulate...

Evaluating flood risk and alterations to hydraulic patterns following installation of low-grade weirs in agricultural systems

Prince Czarnecki, J.M.; Baker, B.H.; Brison, A.M.; … - In: Agricultural Water Management 146 (2014) C, pp. 69-74

decreased drainage and increased flooding in adjacent fields. The purpose of this study was to determine if weirs increased the … risk of flooding and backflow. Analyses were conducted to evaluate the effect of low-grade weirs on hydrology. The first … suggest weirs do not increase flooding potential but merely hold water in ditches longer by slowing return to pre …
