Interpolação dos parâmetros da equação de chuvas intensas com uso do inverso de potências da distância Interpolation of parameters of intensity-duration-frequency equation using the inverse distance to a different powers

Revista Brasileira de Engenharia Agrícola e Ambiental, 2003
As equações de chuvas intensas representam excelente alternativa para a determinação das precipitações críticas utilizadas em projetos de engenharia; contudo, a sua determinação é muito trabalhosa.

Sediment transport by runoff on debris-mantled dryland hillslopes [PDF]

, 2012
Hillslopes supply sediment to river channels, and therefore impact drainage basin functioning and evolution. The relationship between hillslope attributes and sediment flux forms the basis of geomorphic transport laws used to model the long-term ...

Transporte de solutos no solo e no escoamento superficial: I - desenvolvimento do modelo e simulação do movimento de água e escoamento superficial Solute transport in soil and surface runoff: I - model development and simulation of soil water movement and surface runoff

Revista Brasileira de Engenharia Agrícola e Ambiental, 2000
Desenvolveu-se um modelo matemático para simulação do transporte de soluto no solo e no escoamento superficial. As equações diferenciais que regem os processos de transporte são resolvidas numericamente, pelo método das diferenças finitas.

Rainfall and water yield in Macizo del Caroig, Eastern Iberian Peninsula. Event runoff at plot scale during a rare flash flood at the Barranco de Benacancil

Cuadernos de Investigación Geográfica, 2021
Floods are a consequence of extreme rainfall events. Although surface runoff generation is the origin of discharge, flood research usually focuses on lowlands where the impact is higher.

Influence of Climate and Land Use Change on Runoff in Xiying River

Land
In arid inland river basins, the upstream runoff generation zones contribute the majority of the basin’s water resources. Global warming and land use changes will produce uncertain impacts on runoff variations in the headwaters of inland rivers in arid ...
