Optimization of agricultural drainage system design with multiple objectives in a vertisol soil district of China based on DRAINMOD simulations
摘要
Abstract
Owing to the unevenly distributed rainfall, water logging and drought hazards happen concurrent- ly almost every year in the poorly drained vertisol soil district in the Huaibei Plain of China. The existing drainage system was designed for single objective of water logging control, which neglected equal needs of drought prevention and water quality protection. With the aid of the field hydrology model-DRAINMOD, this paper presents a simulation study of drainage system design considering multiple objectives including maximizing crop yields, minimizing subsurface drainage, and land saving etc. The results show that the op- timized subsurface drainage system layout for the study area is placing the drain pipes at depths no deeper than 1.2m and spacing between 18 to 30m. The analysis also shows that replacing the existing open drain- age ditches at field level may save land area of more than 10% in the study area.关键词
