INEXACT SECTOR-WISE PLANNING OF LAND AND WATER RESOURCES IN A LARGE CANAL COMMAND IN THE SUB-HUMID REGION OF EASTERN INDIA

Abstract

A stepwise linear programming (SLP) is utilized for solving the land and water resources management problem. The formulated model considers integrated planning of surface water and ground water resources. The developed model is applied to Hirakud command area of western Odisha. The western part of Odisha faces acute shortage of drinking water almost every year. The study area is bounded by Mahanadi river in the west. Model is applied for the major crops in the canal command area. The model is evaluated for different inexact bounds on available natural resources (land and water). The model results are useful in evolving crop specific land utilization levels and quantities of surface and ground water resources for deriving maximum benefit. The model also provides season specific crop scheduling information. The performance evaluation study shows potential applicability of the developed methodology.
