Differential Changes in Water and Sediment Transport Under the Influence of Large-Scale Reservoirs Connected End to End in the Upper Yangtze River

open access: yesHydrology
The analysis of changing trends of river runoff and sediment discharge and the exploration of their causes are of great significance for formulating sustainable development measures for river basin systems.

Assessment of Nutrient and Bacteria Contributions from Watersheds with Predominantly Agricultural and Urban Land Uses in Coastal North Carolina

open access: yesHydrology
Excess concentrations of fecal indicator bacteria, nitrogen, and phosphorus have caused closure of shellfish growing waters, swimming advisories, eutrophication, and impairment of aquatic habitat in the Tar–Pamlico Estuary, North Carolina.

Perda de água, solo e fósforo com aplicação de dejeto líquido bovino em latossolo sob plantio direto e com chuva simulada Water, soil and phosphorus loss after cattle slurry application to oxisol under no-tillage and simulated rainfall

open access: yesRevista Brasileira de Ciência do Solo, 2009
A região dos Campos Gerais do Paraná é importante produtora de leite em sistema confinado e, com isso, também geradora de dejeto líquido bovino. Os objetivos deste trabalho foram avaliar perdas de água, solo, P total, P solúvel e P particulado em chuva ...

Runoff

open access: yes, 1973
Contained within the 4th Edition (1974) of the Atlas of Canada is a map that shows average annual runoff patterns. There is a second map, accompanied by bar graphs for selected gauging stations of representive rivers, which expresses the volume of flow by months as percentages of the annual average volume.

Seasonality of runoff and precipitation regimes along transects in Peru and Austria

open access: yesJournal of Hydrology and Hydromechanics, 2017
The aim of this study is to understand the seasonalities of runoff and precipitation and their controls along two transects in Peru and one transect in Austria. The analysis is based on daily precipitation data at 111 and 61 stations in Peru and Austria,

The identification of suitable areas for afforestation in order to reduce the potential for surface runoff in the upper and middle sectors of Buzãu catchment [PDF]

open access: yesCinq Continents, 2015
Deforestations, besides the global climate change, are the main cause of the intensification of f loods and flash - floods in the latest years.

Assessment of runoff contributing catchment areas in rainfall runoff modelling

open access: yesWater Science and Technology, 2006
In numerical modelling of rainfall caused runoff in urban sewer systems an essential parameter is the hydrological reduction factor which defines the percentage of the impervious area contributing to the surface flow towards the sewer. As the hydrological processes during a rainfall are difficult to determine with significant precision the hydrological

Multi-model climatic water balance prediction in the Zala River Basin (Hungary) based on a modified Budyko framework

open access: yesJournal of Hydrology and Hydromechanics, 2020
Providing information on the impacts of climate change on hydrological processes is becoming ever more critical. Modelling and evaluating the expected changes of the water resources over different spatial and time scales can be useful in several fields ...

Runoff on rooted trees [PDF]

open access: yesJournal of Applied Probability, 2019
AbstractWe introduce an idealised model for overland flow generated by rain falling on a hillslope. Our prime motivation is to show how the coalescence of runoff streams promotes the total generation of runoff. We show that, for our model, as the rate of rainfall increases in relation to the soil infiltration rate there is a distinct phase change.
