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 ...

Hydrological simulation of the Jialing River Basin using the MIKE SHE model in changing climate

Journal of Water and Climate Change, 2021
Climate change and human activities have an important impact on the changing environment, leading to significant changes in the basin water cycle process. The Jialing River Basin, the largest tributary of the upper Yangtze River, is selected as the study

Effects of rainfall intensity on runoff and nutrient loss of gently sloping farmland in a karst area of SW China

PLoS ONE, 2021
Nutrient losses from sloping farmland in karst areas lead to the decline in land productivity and nonpoint source pollution. A specially tailored steel channel with an adjustable slope and underground hole fissures was used to simulate the ...

Design Optimization of Biocrust-Plant Spatial Configuration for Dry Ecosystem Restoration Using Water Redistribution and Erosion Models

Frontiers in Ecology and Evolution, 2022
Land degradation is one of the main threats to dryland sustainability in the next decades, hence restoration of the degraded land from drylands is an urgent need to maintain ecosystem functionality and their ability to provide ecosystem services.

Recent anthropogenic curtailing of Yellow River runoff and sediment load is unprecedented over the past 500 y

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance The Yellow River (YR) is the cradle of Chinese civilization. It supports agriculture, social prosperity, and human survival. YR runoff and sediment load have sharply fallen since the late 1980s.
