Summary: This study focused on the impact of water table levels and nitrogen fertilizer rates on potato growth and tuber yield, showing that optimal soil water content and water table management play a crucial role in maximizing crop yields and quality. Adjusting water table levels throughout the season according to crop evapotranspiration can reduce irrigation water requirements and minimize the risks of soil water saturation and yield losses.

Summary: Water is crucial for human survival, but its quality can decline due to pollution and contamination caused by the growing population and industrial facilities. The Water Quality Index is widely used to evaluate surface water quality, and this study explores various models that can help assess water quality in different areas. The level of contamination in water affects its overall quality, and pollution indices are useful tools for measuring pollution levels.

Summary: This study calculates the annual irrigation water requirement and effective irrigation water using remote sensing meteorological data and the principles of the Miami model and water balance. Based on the ratio between the effective irrigation water and irrigation water requirement, an irrigation guarantee capability index is established to evaluate the irrigation guarantee capability in the arid region of northwest China. The analysis also explores the rational allocation of water resources in the northwest arid area through the analysis of irrigation water requirement, effective irrigation water, and irrigation guarantee capacity index from 2001 to 2020.

Summary: The demand for freshwater resources has increased due to escalating global population and increasing drought indices in agricultural zones. Improving water use efficiency in irrigated agriculture through smart monitoring and irrigation control strategies is crucial for sustainable agricultural production. Closed-loop irrigation control strategies, particularly when combined with soil-based, plant, and weather-based monitoring methods, can significantly improve water use efficiency in irrigation scheduling.

Summary: The external corrosion of cast iron water supply pipes is related to the availability of free moisture at the pipe wall. Terrain wetness indices can be used to estimate soil surface moisture content. The study demonstrates the potential of terrain indices to indicate relative soil wetness in urban areas, revealing the potential risk of pipe failure.

Summary: Water deficit, especially in summer, is a significant stress factor for olive oil production. A precision irrigation strategy based on daily trunk growth was compared with different deficit irrigation strategies in a high-density olive orchard. The precision strategy achieved high water savings and productivity, but oil production varied depending on the irrigation strategy.

Summary: This study aimed to evaluate the water quality of Ismailia Canal based on regional and seasonal variability. The results showed that most physicochemical parameters were within acceptable irrigation limits, except for potassium concentrations. Seasonal variation in water quality was significant, while regional variation was not. There were significant correlations between different water quality parameters, with pH being a significant factor affecting the water quality index. It is recommended to treat drainage water before mixing it with irrigation water to improve suitability for irrigation.

Summary: This study proposes a threshold-based method to extract the extent and timing of flood irrigation in the Hetao Irrigation District (HID) in China. The model uses MODIS water indices and robust thresholds to achieve strong generalization capability. Through validation using pixel and field survey data, the model shows an overall accuracy of over 90.0% for the irrigation area.

Summary: A statistical model is used to reconstruct daily terrestrial water storage anomaly (TWSA) by combining monthly GRACE observations with daily temperature and precipitation data. The reconstructed TWSA is utilized to monitor the catastrophic flood event that occurred in the middle and lower reaches of the Yangtze River basin in 2020. The study introduces a modified wetness index (MWI) and a normalized daily flood potential index (NDFPI), which show potential for daily flood monitoring and early warning.

Summary: Plant water deficit index (PWDI) is a critical index for irrigation scheduling that reflects the extent of abiotic stresses. Smart irrigation scheduling based on PWDI thresholds has been suggested to maximize yields and minimize negative environmental effects. A two-year experiment on drip-irrigated cotton under film mulch was conducted to investigate the effects of PWDI-driven irrigation under saline conditions. Results showed that higher PWDI thresholds led to increased irrigation depth but decreased irrigation frequency and total volume, resulting in a deteriorated soil water and salt environment, slower growth, and lower yield and net profit. Guidelines for smart irrigation scheduling were provided based on quantitative results, taking into account water management measures and cotton market prices. An optimal PWDI threshold of 0.49 was found to maximize economic benefits and water productivity. Lower thresholds should be considered when cotton prices are low, while higher thresholds can be used to improve water efficiency. Further research is needed to consider crop sensitivity to water and salinity stresses at different growth stages and optimize irrigation depth per event.

Summary: Nutrient loss in surface runoff from hill country catchments is typically generated from small areas and over short time periods. This study compared nutrient and sediment losses in surface runoff on two hill country sub-catchments with contrasting soil types. The results highlight the potential benefit of strategically placing cattle feed supplements on soils less prone to surface runoff to improve freshwater outcomes.
