Vineyards represent complex Mediterranean agrosystems that deliver significant ecosystem services to society. Yet, many vine-growers still need assimilate the importance of crop and soil management conservation water resources. The main objective this study was evaluate use balance terms in rainfed irrigated vineyards Italy Portugal, respectively, both cases aiming at sustainability natural resources use. SIMDualKc model is used for sites after calibration validation by fitting content...
Abstract The main goal of this study was to estimate inflows the Maranhão reservoir, southern Portugal, using two distinct modeling approaches: a one-dimensional convolutional neural network (1D-CNN) model and physically based model. 1D-CNN previously trained, validated, tested in sub-basin area where observed streamflow values were available. trained here subject an improvement applied entire watershed by replacing forcing variables (accumulated delayed precipitation) make them correspond...
Guadiana international catchment, located in the Iberian Peninsula. The River catchment has registered an intense and speed up modification of its natural regime over last few decades to cope with water scarcity. Such modifications pose a serious challenge development improved management tools as information on available resources is often not detailed enough. This study aimed simulate flow using MOHID-Land model during 30 years period. Two scenarios were defined by considering (or not)...
Abstract Water distribution in sprinkler irrigation systems remains one of the most challenging problems water management. Due to lack uniformity, parts a field may be over‐irrigated while others under‐irrigated, thus affecting root and nutrient uptake crop yield. The objective this paper was show capabilities MOHID‐Land model simulating soil dynamics maize growth under stationary system with low uniformity (56%). A 3D simulation domain (28 × 26 1 m) defined consider different application...
The southern Iberian Peninsula is characterized by evergreen oak woodlands (locally known as montado), which constitute an important savanna-type agro-silvo-pastoral ecosystem. This ecosystem facing a progressive decline for several reasons, with the foremost being overgrazing. Better management tools are necessary to accurately quantify systems’ carrying capacity and sustainable stocking rates that prevent land degradation. purpose of this study was determine whether MOHID-Land model could...
Hydrological modeling at the catchment scale requires upscaling of many input parameters for better characterizing landscape heterogeneity, including soil, land use and climate variability. In this sense, remote sensing is often considered as a practical solution. This study aimed to access impact assimilation leaf area index (LAI) data derived from Landsat 8 imagery on MOHID-Land’s simulations soil water balance maize state variables (LAI, canopy height, aboveground dry biomass yield). Data...
Hydrological models are increasingly used for studying watershed behavior and its response to past future events. The main objective of this study was conduct a sensitivity analysis the MOHID-Land model identify most relevant parameters/processes influencing river flow generation. is complex, physically based, three-dimensional catchment-scale applications. A reference simulation implemented in Ulla River watershed, northwestern Spain. focused on sixteen water dynamics at that scale....
Hydrological modeling is nowadays critical for evaluating the status, past trends, and future perspectives of water availability at global, regional, local scales. The Iberian Peninsula registering more frequent severe droughts scarcity caused not only by extreme meteorological events, but also increased demand urban, industrial, agricultural supplies. Better simulation models are thus needed accurately quantifying resources. In this study, natural flow regime in different watersheds was...
The success of an irrigation decision support system (DSS) much depends on the reliability information provided to farmers. Remote sensing data can expectably help validate that at field scale. In this study, MOHID-Land model, core engine IrrigaSys DSS, was used simulate soil water balance in irrigated vineyard located southern Portugal during three growing seasons. Modeled actual basal crop coefficients and transpiration rates were then compared with corresponding estimates derived from...
The IrrigaSys decision support system (DSS) has supported farmers’ decision-making regarding irrigation scheduling in the Sorraia Valley district Southern Portugal over a span of six years (2017–2022). This study aims to conduct postevaluation adherence DSS, employing multicriteria analysis (MCA) approach with data from 2019 (driest year) and 2020 (average growing seasons. Two distinct scenarios were taken into consideration: first focused on water conservation, second centered economic...
<p>Currently hydrological models are not generally coupled to coastal and regional ocean because, even if regarded as a powerful useful tool, they do fully accomplish estimate accurately the right volume of water reaching zone for many reasons including management activities such human consumption, irrigation, etc. For this reason, continue use river climatologies boundary conditions representing an active boundary. Furthermore, continuous salinity observations in area scarce...
<p>The WATER4EVER Project (http://water4ever.eu/) was built on the premise that agriculture is by far largest consumer of water, with about 70% diverted water being used in irrigation. Agriculture also considered as a key source diffuse pollution inefficient practices resulting high and nutrient (particularly N P) surpluses are transferred to bodies through processes (runoff leaching), promoting eutrophication, associated biodiversity loss. aims thus develop new monitoring...
A modelação do balanço de água no solo desempenha hoje um papel fundamental ao nível da otimização das práticas rega, ajudando a definir, com rigor, os calendários rega em função necessidades hídricas culturas, propriedades hidráulicas e características dos equipamentos. No entanto, para tal, é necessário que o modelo seja sujeito previamente intenso processo calibração validação as suas previsões sejam confiáveis. Este trabalho tem como objectivo simular dinâmica numa vinha regada na região...
The coupling of coastal or regional ocean models to hydrological observed data is currently an uncommon practice in operational oceanography. Though are regarded as a powerful and useful tool for estimating the quantity quality freshwater running watershed, they fail provide accurate results river flow reaching area due water-management activities occurring within catchment, such human consumption, irrigation, storage, etc. For this reason, many continue impose surface zero-salinity...

Existem atualmente uma série de ferramentas (modelos, sensores, produtos deteção remota) apoio à gestão da rega, mas que pelas suas especificidades técnicas, são difíceis utilizar pelos agricultores ou serviços extensão rural. Este trabalho apresenta o sistema decisão IrrigaSys (irrigasys.maretec.org) integra base dados, um modelo baseado em processos físicos, imagens satélite e interface gráfica online. tem sido desenvolvido ao longo dos últimos 5 anos, prestando rega a cerca 103 parcelas...
<p>Watershed modelling is one of the most important assessment tools in watershed planning and management. Nonetheless, classic calibration models, which a few discharge gauges near outlet catchment are used to compare measured simulated streamflow, often criticized by not assuring that relevant processes such as evapotranspiration, soil moisture, crop growth, groundwater recharge well represented area. This study aimed simulate streamflow two Mediterranean catchments, Orba...
