1.1 Objective of investigation
Objectives of investigation for two parts data are to obtain crop pattern and irrigation water volume change with time, and to supply parameter for irrigation water optimal allocation model.
1.2 Investigation spots and items
Investigation spots include six water management stations that are Dangzhai, Hua’er, Daman, Xiaoman, Jiantan, and Ershilidun, respectively, at Daman irrigation district. Investigation items comprise water allocation time, branch channel inflow, Dou channel inflow, irrigation area, channel water use efficiency, water price, and water fee. Investigation time is described as followed:
2012.03.16 to 2012.04.04, Spring irrigation;
2012.04.04 to 2012.05.14, Summer irrigation;
2012.05.20 to 2012.06.24, Summer irrigation;
2012.05.16 to 2012.07.06, Summer irrigation;
2012.07.15 to 2012.08.02, Autumn irrigation;
2012.08.10 to 2012.08.26, Autumn irrigation.
Investigation spots include eight water management station that are Chang’an, Shangqin, Dangzhai, Liangjiadun, Shimiao, Xiaoman, Xindun, and Yangou, respectively, at Yingke irrigation district. Investigation time and items is described as followed:
