Tipping bucket rain gauges (TBR) are widely used worldwide because they simple, cheap, and have low-energy consumption. However, their main disadvantage lies in measurement errors, such as those caused by rainfall intensity (RI) variation, which results data underestimation, especially during extreme events. This work aims to understand these types of identifying some causes through an analysis water behavior its effect on the TBR mechanism when RI increases. The mechanical biases effects...
Water, energy, and food security are essential for human health and  development. However the increasing demand for natural resources, has surpassed capacity of multiple ecosystems is compromising their sustainability resilience. The management these resources interconnected, cannot be managed independently, since water energy production. Also crucial maintenance ecosystems, so WEFE NEXUS emerges as a resource strategy.In Spanish demarcation Duero River basin, scarcity...
Tipping bucket rain gauges (TBRs) have been, and apparently will continue to be one of the most widely used pieces equipment for rainfall monitoring, being frequently calibration, validation downscaling radar remote sensing data, due their major advantages–low cost, simplicity, low energy consumption. Thus, many works focused focus on main disadvantage–measurement biases (mainly in wind mechanical underestimations). However, despite arduous scientific effort, calibration...
Hydrologic processes acting on catchments are complex and variable, especially in mountain basins due to their topography specific characteristics, so runoff simulation models water management also complex. Nevertheless, model parameters usually estimated the basis of guidelines from user manuals literature because they not monitored, high cost conventional monitoring systems. Within this framework, a new promising generation low-cost sensors for hydrologic monitoring, logging, transition...
A novel methodology for the optimal placement of sensors in watercourses is presented. The aimed at finding locations to maximize amount information monitor flow and velocity watercourses. based on maximization Gram determinant sensor responses each possible location or a combination locations. Two illustrative examples are presented wherein one- two-sensor cases monitoring Venero Claro River Basin, Spain, selected. kinematic wave method was used evaluate response every location. results...
This paper presents a novel approach to assess spatial and temporal irrigation performance in urban parks can assist park manager/operator decisions management. First, needs are estimated by traditional scheduling the zones with similar water that share same electric valve (hydrozones) identified. Then, is calculated using relative supply (RWS) indicator mapped (GIS software). be adapted various scales. In this study, it was applied Valdebebas development VBB (Madrid) between 2017 2019...
The Duero basin is the largest watershed in Iberian Peninsula, with a surface of 98.073 km2 distributed Spain and Portugal. 80% area (78.891 km2), where plays an important role for country’s energy food production. However, region, droughts are frequent have increased last years stressing water resources creating competition friction among users. Likewise, demand irrigation has also as along fertilizer prices. uncertainty on future critical it must be managed. Within this context,...
Water scarcity and water stress have become a concern for many countries worldwide, especially to Mediterranean like Spain. Which, together with the increase in energy prices, affected food production degraded ecosystems. Over last two decades Spain, irrigated areas expanded interest of modernizing irrigation systems cope increased consumption promote economic development maintenance rural population. At same time, managing – rising fertilizer prices necessities, but also...
Water stress, together with rising energy prices, have become a major concern worldwide, especially for food production (the water consumer) that leads to ecosystem degradation in arid and semiarid countries such as Spain. The Spanish irrigated area ​​ has been continuously expanding modernizing response the demant increase promote economic development support rural areas which are aspects generally considered on an individual basis, against advice of international...
Tipping bucket rain gauges are worldwide implemented due to their simplicity, low-energy consumption, and cheaper cost. Being main disadvantage measurement biases caused by different factors such as wind, mechanical, etc. This work focus on errors rainfall intensity variation, its effect into the mechanism, which results in underestimation, specially at extreme events. Aiming understand these identifies causes. A semi-analytical simulation based gauge mechanism response has been developed...
<p>Precipitation measurement has always been of human interest. Its estimation can guide the decisions concerning flooding prevention and irrigation scheduling in semi-arid regions.</p><p>Nowadays, manufactures offer several types rain gauges. Among them, tipping-bucket gauges (TBRs) is most frequently used worldwide to collect rainfall data. It structure simple manufacturing cost reasonable. Also, operating mechanical mechanism saves energy be...
<p>For annual cropping systems sensitive to water stress, such as citrus, efficient management can allow facing their large consumption and enhancing crop sustainability. However, apply water-saving strategies it is necessary monitoring soil and/or plant status. In the last decade, a wide number of sensors providing indirect measurements volumetric content based on physical properties, dielectric permittivity or matric potential, have been developed. Among using frequency...
