AbstractOne of the main challenges of water scarcity is the water consumption in the agriculture sector. Therefore, optimizing water consumption and applying an optimal management in the agriculture sector is necessary. The implementation of a participatory management of water resources in the rural areas and the creation of Water User Association (WUA) can be a successful approach towards this management. That requires the continuity of the management, the comprehensive participation of farmers, and the exploitation of water resources; however, this action needs to understand the factors affecting the behavior of consumers. Thus identifying the factors influencing farmers’ intentions towards participation in WUA is essential. The purpose of this study is to identify factors affecting farmers' intentions towards participation in water user association, by theory of planned behavior (TPB). There are 21 agriculture water pumping stations active in Lorestan Province. Farmers at each agriculture water pumping stations make up a Water User Association. The population of this study consisted of all WUAs in western Iran (N = 1990), and through a proportional stratified random sampling technique farmers were selected (N = 133) from the population. Moreover, the validity of the questionnaire was confirmed by a panel of experts. The reliability of the questionnaire was calculated at pre-test stage for different parts of the questionnaire ranging from 0.83 until 0.91. The collected data were analyzed using Statistical Package for the Social Sciences 20 software. The results revealed that there were effective variables including subjective norm, attitude, and extension training courses which contributed to the importance of participation in the water management, and that the educational level of farmer was a controlled variable that could affect farmers' attitudes towards participating in Water User Association; these factors could explain 53% of farmers' participation totally.

In this article, a general methodology for simulation of water resources management is suggested. The research has been conducted in three different levels: a deep analysis of the historical management procedures, the development of some alternative ways to optimal management, and the establishment of planning criteria at short, middle, and long term. The main constraints, divided into three categories according to the severity of probable losses, have been defined as a function of several expected goals: hydro power, flood control, recreational activities, etc. The model was applied with excellent results to the upper region of the St. François river basin (Québec, Canada). Key words: simulation, resources management, mathematical models, optimization.

In the article efficiency of water distribution in the territory of Amu-Surkon basin is analysed and based on the results, provided the recommendations. The study is conducted within the project QH-A-QH-2018-409 “Increase efficiency of water resources management in Surkhandarya region: improve interbasin re-distribution of the water resources of Surkhandarya and Sherabaddarya Rivers” funded by Uzbekistan government. The main problems of water management in the Surkhandarya region are: outdated irrigation systems requiring an urgent modernization; large dependence on pump irrigation; low energy efficiency of pumping stations due to use of the old high energy-consuming equipment; irrational distribution and large unproductive technical and operational water losses. Increase of sensitivity to climate change with forecasting of 50% water deficit by 2050 leads to drought and further desertification, including impact on food security. In the article some results are introduced related to improve water allocation by redistribution of water resources between the river basins in the region aimed to reduce of pumped water use for irrigation.

Abstract The subtropical monsoon climate zone is featured with the abundant water resources but uneven temporal and spatial distribution, so seasonal water shortages are frequent. In order to reduce the water shortage and water spill in this region, a nonlinear optimization model for the joint operation of a system of a reservoir and two pumping stations is developed in this paper. In this model, the water supply of reservoir and pumping volume of pumping stations in each period are two types of decision variables, which are subjected to the annual available water in the reservoir, water rights of the two pumping stations and the operation rule of reservoir. However, the modern intelligent algorithms may fail in dealing with constraints of if statements like the operation rule of reservoir in this model. In light of the shortcoming of the classical genetic algorithm, a modified genetic algorithm is proposed by comparing the different methods for dealing with constraints. The modified algorithm showed a better adaptability to the operation rule. The modified genetic algorithm may provide a reference for similar modern intelligent algorithms to solve optimal water resources allocation for multiple reservoirs and multiple pumping stations system.
