“…In this scenario, AH sensors can be involved as an advantageous tool to measure the water levels within a crop field and hence to quantitatively characterize the irrigation, both from a spatial and temporal point of view. That information can then be used to calibrate and validate models useful to guide the decision-makers to establish scientific-based guidelines for the farmers (Costabile et al, 2023). As an example, here we report the evolution in time of the irrigation wavefront (Figure 8) measured during a border irriga- tion event on July 20, 2021.…”

“…It can be appreciated that, initially, the field starts to be gradually filled by the water (profiles 20 min, 30 min and 40 min in Figure 9), subsequently, there is a phase where the water levels remain almost stable along the agricultural field (profiles 50 min and 60 min in Figure 9) and finally, it begins to empty (profile 70 min in Figure 9) after the interruption of irrigation. Data obtained from this experimental campaign by using AH devices as water level detectors could be employed to better understand border irrigation dynamics and in particular to describe both waterfront advance and recession, calculate the intake opportunity time, estimate uniformity of water distribution onto the field or calibrate hydrodynamical models (Costabile et al, 2023;Salahou et al, 2018).…”

“…The field is about 1.5 ha in size, divided into 4 borders, three of which have a quasi-rectangular shape of approximately 30 m in width and 120 m in length. The slope is about 0.61%, with a regular longitudinal profile, which was determined through a photogrammetric drone flight (Costabile et al, 2023). Closed-end border irrigation is the method for watering each border.…”

In this paper, we present ArduHydro, a low-cost device for water level measurement and monitoring designed for employment in controlled and outdoor environments. It measures the water level through an ultrasonic sensor and elaborates the signals through an Arduino microcontroller. The small size of this device, its robustness and accuracy make ArduHydro properly versatile for different applications in the field of water control and management. This article describes the design, the components, the costs, and the performance of ArduHydro. The performance was assessed with a laboratory test inside an open-channel flume and comparing ArduHydro measurements with those obtained with a traditional ultrasonic sensor. Furthermore, an example of ArduHydro application for detecting the wavefront evolution during surface irrigation of a maize crop is presented. The results revealed that ArduHydro measurements were, on average, very consistent with those obtained by the traditional ultrasonic sensor in all different flow conditions. The application of ArduHydro during a surface watering of an agricultural field allowed us to obtain important spatiotemporal information about the water depth along the longitudinal direction of the field, paying the way for a real comprehension of the dynamics of wavefront evolution in a real-world case study.

In our era, the rapid increase of parallel programming coupled with high‐performance computing (HPC) facilities allows for the use of two‐dimensional shallow water equation (2D‐SWE) algorithms for simulating floods at the “hydrological” catchment scale, rather than just at the “hydraulic” fluvial scale. This approach paves the way for the development of new operational systems focused on impact‐based flash‐floods nowcasting, wherein hydrodynamic simulations directly model the spatial and temporal variability of measured or predicted rainfall on impacts even at a street scale. Specifically, the main goal of this research is to make a step to move toward the implementation of an effective flash flood nowcasting system in which timely and accurate impact warnings are provided by including weather radar products in the HPC 2D‐SWEs modelling framework able to integrate watershed hydrology, flow hydrodynamics, and river urban flooding in just one model. The timing, location, and intensity of the street‐level evolution of some key elements at risk (people, vehicles, and infrastructures) are also discussed considering both calibration issues and the role played by the spatial and temporal rainfall resolution. All these issues are analyzed and discussed having as a starting point the flood event which hit the Mandra town (Athens, Greece) on the 15 November 2017, highlighting the feasibility and the accuracy of the overall approach and providing new insights for the research in this field.

“…The sensors were installed just before the beginning of the irrigation intervention and removed right after the water depth across the eld was completely depleted. In Field A, the water level sensors were installed at 5, 10, 15, 20, 30, 50, 75, 105, 140 and 175 m from the head of the eld; in Field B they were located at 10, 15, 20, 30, 40, 50, 60, 70, 85, 100 m. More information on the instrumentations and monitoring procedures adopted in both experimental elds can be found inMasseroni et al (2022) andCostabile et al (2023).…”

The effects of climate change on water availability affect the performance of surface irrigation, which is the oldest and most common method of water application to row crops worldwide. A paradigm shift towards strategies aimed at increasing flexibility of irrigation scheduling and improving the design and management of field layouts and irrigation practices should be explored to promote water savings at the farm scale. In this study, we investigate how adopting a more flexible irrigation scheduling and optimizing irrigation management variables and field layout it is possible to increase the efficiency of border irrigation and thus achieve water savings and improve quality of crop production. The analysis of the actual performance of border irrigation was carried out on two maize fields located in the Padana Plain (Northern Italy) in two years characterized by different rainfall patterns (i.e. 2021 and 2022). Based on this information, continuous monitoring of soil moisture status combined with the AquaCrop-OS agro-hydrological model was used to manage flexible irrigation scheduling over the experimental fields. While the optimization of irrigation management (flowrate per unit width and cutoff time) and field geometries (border width and slope) was studied using WinSRFR 5.1 USDA software, which was properly calibrated by measures of waterfront advance and recession. The results show that with flexible irrigation scheduling and proper irrigation management and field layout, significant water savings can be achieved. Specifically, in the case study, seasonal water savings of about 10% were obtained just by scheduling irrigation based on actual crop water needs in a very dry agricultural season, while water savings reached up to 60% in a wetter season. On average, an additional 7% of water savings was achieved over the agricultural season when the irrigation duration was correctly applied to each border of the experimental plots, while approximately 20% of water was saved when the border width was correctly designed based on inflow availability. These results provide useful information for improving the management of border irrigation in practice, both under current conditions and in the face of increasing freshwater scarcity in the future.
