Faced with water scarcity and its rising costs, it is necessary to use it in a rational way. This study proposes the development of an autonomous system of water monitoring in condominiums (smart house), through meters that use turbine flow sensors and ZigBee technology for sending data to a coordinator, allowing monitoring of the consumption at various points of a building in almost real time. Users can read the consumed volume throughout a smartphone application. This stimulates a more rational way of using water, besides allowing to alert for leaks in pipes, faucets, showers and toilets. The accuracy of this sensor was compared with a mechanical flow meter and an ultrasonic sensor in the laboratory, all presenting errors smaller than 10% of readings for water flow above 2 L/min. The quality of the ZigBee network was analysed, in terms of interference with Wi-Fi, Bluetooth devices and a microwave oven, to assess if there are data losses in the sensor network and only Bluetooth caused losses, showing robustness in the combined ZigBee and Wi-Fi.

Most current water allocation strategies fail to address the unbalanced development among multiple systems. How to optimize the coordination development relationships among the social, economic and environmental systems has always been the focus. To bridge this gap, this study innovatively constructed a water optimal allocation model for coordinated development and applied it to the main stream of the Xiangjiang River Basin, China. The results showed that: (i) In 2025, the water deficit ratio of the study area will increase from 3.21 to 5.50% when P = 50% and from 4.59 to 6.85% when P = 75%. The existing water supply capacity will not be able to meet the increasing water demand. (ii) Agricultural and industrial water will account for a large proportion of the total water consumption. Due to the transformation of industrial structure, measures should be formulated to bring the best benefits. (iii) Restricted by different systems, the coordinated development in each city will present spatial and temporal differences. (iv) The proposed model was proved to overcome the backwards of uncoordinated development and achieve a balance of the regional social, economic and environmental benefits. Also, some recommendations and limitations were discussed. This study provides an effective basis for enhancing regional sustainable water resources planning and management.

Water resources are important factors limiting social and economic development, so how to ensure the coordination between economic development and water resources–ecological management capacity has become a key issue that needs to be addressed urgently for China’s high-quality economic development. This paper used nighttime light data as proxy variables of economic development to calculate the coupling coordination degree between provincial economic development and water resources–ecological management capacity in China from 2004 to 2019 based on the coupling coordination degree model; w constructed a spatial econometric model to explore the spatial correlation and influencing factors between economic development and water resources–ecological management capacity. The results are shown in the following: (1) The overall level of China’s economic development is on an upward trend, but the regional development is unbalanced, showing a decreasing spatial pattern distribution of the eastern coastal region–mid-western region–far-western region. (2) The level of water resources–ecological management capacity is low, and the spatial distribution shows a decreasing trend in the far west–central and western–eastern coastal regions. (3) The level of coupling and coordination between economic development and water resources–ecological management capacity rises from a mild imbalance level to a little imbalance level, and the spatial distribution is consistent with the spatial distribution of economic development. (4) The factors influencing the level of coupling and coordination of inter-provincial economic development and water resources–ecological management capacity in China mainly involve the population scale, technological progress, affluence, and foreign direct investment. Each province and city should take into account its own actual situation and develop targeted measures to promote the coordinated development of economic development and the water resources–ecological management capacity.
