Mathematical models of the quantity and quality water in hydrographic basins enable simulation a wide variety processes, including production sediments, dynamics point nonpoint sources pollution. These have become increasingly complex, requiring large amounts input data, which can increase uncertainty results simulations. For this reason, it is essential to perform calibration validation procedures. The objective work was conduct sensitivity analysis distributed hydrological model (SWAT)...

This study introduces the modified sequent peak algorithm (MSPA 2024), an advanced reservoir design framework that incorporates resilience as a key performance metric alongside traditional measures like reliability and vulnerability. By integrating thresholds, MSPA 2024 addresses complexities of water resource management under diverse hydrological conditions demand scenarios. Comparative analyses reveal surpasses approaches, such behavior analysis (BA) earlier versions, particularly in...

The Paraguaçu watershed in northeastern Brazil faces increasing water scarcity, with resources unable to meet the demand. Accurate assessment of availability is thus essential for efficient planning and management local resources. In this work, potential SWAT model predicting daily monthly variability hydrologic regime River was assessed. Model calibration/validation followed: (i) A hierarchical framework; (ii) maximum, average minimum streamflow based on paired t-test linear regression...

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...

Management decisions related with water quality in lakes and reservoirs require a combined land-water processes study approach. This reports on an integrated watershed-reservoir modeling methodology: the Soil Water Assessment Tool (SWAT) model to estimate nutrient input loads from watershed, used afterwards as boundary conditions reservoir model, CE-QUAL-W2. The system was applied Torrão drainage basin. objective of quantify total maximum load that allows be classified mesotrophic. is...

Over the past decades, water quality models have become unique tools in management of aquatic resources. A consequence their widespread application is significant number now available. Available methodologies to compare provide limited support for choice first place, especially end-users or modelers with experience. Here we propose a method assist selection particular model from set apparently similar models. The termed ScoRE, as it grades according three main aspects: Scope (aim, simulated...

Abstract Rhipicephalus sanguineus Latreille (1806) (Ixodida: Ixodidae) is considered to be the most widely distributed tick and have a vast range of habitats hosts, including livestock, pets wildlife. In addition morphological differences, recent investigations using approaches based on molecular genetic markers revealed existence different R. lineages in geographic regions. this study, 475 ticks collected from dogs western Iberian peninsula were studied both morphologically genetically, 12S...

Water resources are impacted by several stressors like over-population and over consumption that compromises their availability. These expected to progressively intensify due climate change in most regions of the world, with direct impact on watersheds river systems. This study investigates effect different watershed pressure scenarios hydrological regime Sorraia River basin, Portugal. catchment includes one largest irrigated areas country, thus being strongly influenced anthropogenic...

Evapotranspiration is a process driven by weather, vegetation, and soil conditions. The complex interrelations among these parameters have been modelled numerous remote-sensing energy balance algorithms. When estimating evapotranspiration on regional scale, the spatial variability of weather important thus closer attention to meteorological input data required. aim this work improve accuracy actual integrating outputs from model into remotely sensed model. In order achieve this, time series...

Abstract This study describes an integrated modelling approach to better understand the trophic status of Montargil reservoir (southern Portugal) under climate change scenarios. The SWAT and CE-QUAL-W2 models were applied basin reservoir, respectively, for simulating water nutrient dynamics while considering one climatic scenario two decadal timelines (2025–2034 2055–2064). Model simulations showed that dissolved oxygen concentration in reservoir's hypolimnion is expected decrease by 60%...

This paper describes an integrated modelling approach to study water use vulnerability in a typical Mediterranean basin under different climate change projections. The soil assessment tool (SWAT) and the MOHID (from modelo hidrodinâmico) Water model were used evaluate impacts of two scenarios (GFDL-ESM2M IPSL-CM5A-LR) on availability Montargil’s reservoir (Portugal) during decadal timelines (2030 2060). Reservoir performance metrics estimated considering also demand scenarios: average last...

There is an increasing variety of hydrometeorological information sources available for operational water management.These comprise in-situ measurements, Earth Observation, meteorological models, and hydrological models.The effective use all these together challenged by two aspects.First, there communication technology (ICT) challenge acquiring, processing, merging, presenting the various data streams operationally.Secondly, are methodological gaps on how to integrate multiple in a useful...
