Topography and hydrology modeling and influence on soil erosion simulation, at ...
Duarte, A.C.; Ferreira, Carla; Vitali, GiulianoDiffuse pollution from agricultural activities is a major environmental problem. The extent of the impacts is driven, e.g., by local topography due to the influence on hydrological processes. This study aims to investigate the use of dif-ferent scale topographic data in assessing runoff-erosion processes. The TopAG-NPS module, a component of the AnnAGNPS model (Annualized Agriculture Nonpoint Source), was used ...
Modelação da topografia do terreno e simulação da erosão hídrica numa pequena b...
Duarte, A.C.; Ferreira, Carla; Vitali, GiulianoNa simulação dos impactes das atividades agrícolas na poluição difusa à escala da bacia hidrográfica, é importante uma adequada configuração topográfica do terreno e a compreensão do seu comportamento hidrológico. Neste estudo foi utilizado o módulo FlowNet Generator, componente do modelo AnnAGNPS (Annualized Agriculture Nonpoint Source), para avaliação da influência da resolução vertical do Modelo Digital do T...

Sustainable water management in horticulture: Problems, premises, and promises
Ferreira, Carla; Soares, Pedro R.; Guilherme, Rosa; Vitali, Giuliano; Boulet, Anne; Harrison, Matthew Tom; Malamiri, Hamid; Duarte, A.C.Water is crucial for enduring horticultural productivity, but high water-use requirements and declining water supplies with the changing climate challenge economic viability, environmental sustainability, and social justice. While the scholarly literature pertaining to water management in horticulture abounds, knowledge of practices and technologies that optimize water use is scarce. Here, we review the scienti...

Use of simulation models to aid soil and water conservation actions for sustain...
Duarte, A.C.; Ferreira, Carla; Vitali, GiulianoAdequate planning of soil and water conservation requires understanding and prediction of the interactions between soil, climate and management scenarios. These interactions have been investigated over the last decades by means of modelling tools. Some of the most widely used models, namely KINEROS, WEPP, SWAT, and AnnAGNPS have been compared in terms of interfaces, processes, data and parameter requirements, t...
