Daily Weather Forecasts Used to Manage Soil-Water

by James L. Fouss, USDA, ARS, Baton Rouge, LA, USA,
Richard C. Thompson, USDA, ARS, Baton Rouge, LA, USA,



Document Type: Proceeding Paper

Part of: Development and Management Aspects of Irrigation and Drainage Systems

Abstract:

This paper describes a newly developed method for analyzing the rainfall probability data included in daily weather forecasts issued by the National Weather Service. The purpose is to aid the farmer or farm manager in daily management/control decisions for operating water management systems in humid climate conditions. The method is illustrated by computer simulation results for a 'controlled' water table management system (combination subsurface drainage-irrigation system), with the daily weather forecast analysis used as a means to decide if and when the controller of the water management system should be manually 'overridden'.
