| Abstract: |
| Aimed at the liberty of water order and the low water use efficiency, with close linking to the management rules of the Yellow River water and based on real-time irrigation forecast and the fuzzy cluster theory, a management system is developed for allocation of the irrigation water resources in the lower reaches of the Yellow River, including crops water demands sub-model and real-time water order sub-model.The factors of soil moisture, rainfall and weather types are thought of in the crops water requirement sub-model.The management systems and the software are used in Qucun irrigation area, and the results are reasonable.The system can be used to improve the water use efficiency and give suggestions to the operators. |
