Integrated Decision Making for Reservoir, Irrigation, and Crop Management

An integrated approach to reservoir, irrigation, and cropping management which links four di€erent modelsÐa hydrologic model (PRMS), a crop growth simulation model (EPIC), an economic model based on linear programming, and a dynamic programming modelÐis developed and demonstrated. The demonstration is based on an irrigation district located in a subhumid climate with an irrigation reservoir lar...

CropIrri: A Decision Support System for Crop Irrigation Management

A field crop irrigation management decision-making system (CropIrri) was developed based on the soil water balance model, crop phenology model, root growth model, crop water production function, and irrigation management model. The irrigation plan is made through predicating of soil water content in root zone and daily crop water requirement using historical and forecasting weather data, measur...

Corn yield responses under crop evapotranspiration-based irrigation management

Improving irrigation water management is becoming important to produce a profitable crop in South Texas as the water supplies shrink. This study was conducted to investigate grain yield responses of corn (Zea mays) under irrigation management based on crop evapotranspiration (ETC) as well as a possibility to monitor plant water deficiencies using some of physiological and environmental factors....

Developing a GIS-based Spatial Decision Support System for Automated Tree Crop Management to Optimize Irrigation Inputs

In recent years there has been a growing interest in the application of geographic information systems (GIS) for the development of spatial decision support systems (SDSS). The current paper presents the development of a GISbased SDSS for precision management of tree crops. The SDSS is being developed within the framework of the '3D-Mosaic' project which aims at optimizing water consumption in ...
