Modelagem matemática do escoamento superficial na escala de encosta sob plantio direto
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloCentro de Ciências Rurais, 2017-02-24)
The runoff generation over fields with no-tillage agriculture management remains being a
problem with environment, social and economic impacts. The purpose of this research was
evaluate the capacity of a physic based and ...
Comportamento hidrológico de pequenas bacias hidrográficas pareadas com campo e eucalipto no bioma Pampa.
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloCentro de Ciências Rurais, 2023-02-27)
With the growing demand for forestry, especially eucalyptus and pine plantations for the
production of wood, pulp and resins, concerns have increased about the impacts on the
conservation of water resources, especially ...
Hydrological model for urban catchments - analytical development using copulas and numerical solution
(TAYLOR & FRANCIS LTD, 2010)
A model based on analytical development and numerical solution is presented for estimating the cumulative distribution function (cdf) of the runoff volume and peak discharge rate of urban floods using the joint probability ...
Análisis comparativo del comportamiento de la escorrentía de tres microcuencas andinas con diferente régimen de precipitación y cobertura vegetal
(Universidad de Cuenca, 2017)
The paper presents a descriptive comparative analysis of the precipitation and runoff of three Andean
small watersheds (varying in size between 0.6 and 1 km2), using approximately 8 years of rainfall and
discharge data, ...
Combined use of isotopic and hydrometric data to conceptualize ecohydrological processes in a high-elevation tropical ecosystem
(JOHN WILEY AND SONS LTD, 2016-08-15)
Few high-elevation tropical catchments worldwide are gauged, and even fewer are studied using combined hydrometric and isotopic data. Consequently, we lack information needed to understand processes governing rainfall–runoff ...
Water quantity investigation of simulated green roofs in a tropical climate: influence of vegetation composition
(Universidade Federal de Mato Grosso, 2019)
Analysis of the behavior of abstractions in two urban micro-basins of the city of Cuenca (Ecuador), through an aggregate model
(2021)
Several cities in developing countries are challenging the permanent process of urbanization. This generates a great disturbance on the hydrological response of the urbanized area during rainfall events, which can cause ...
Perdas de água e sedimento em bacias pareadas de ordem zero sob plantio direto com e sem terraço
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2015-07-28)
Tillage is a conservation technique for soil management, whose principles are avoiding soil
disturbance, straw maintenance on the surface and crop rotation. Currently, negligence in its
use leads to situations of land ...
Runoff measurement and prediction for a watershed under natural vegetation in central BrazilMedição e simulação do escoamento superficial para uma microbacia hidrográfica sob vegetação natural localizada no centro-oeste brasileiro
(Sociedade Brasileira de Ciência do Solo, 1999)
This work aimed to measure and analyze total rainfall (P), rainfall intensity and five-day antecedent rainfall effects on runoff (R); to compare measured and simulated R values using the Soil Conservation Service Curve ...
Spatial distribution of runoff depth from a watershed located in a cuesta relief area of São Paulo State, Brazil
(2014)
This study was undertaken in a 1566 ha drainage basin situated in an area with cuesta relief in the state of São Paulo, Brazil. The objectives were: 1) to map the maximum potential soil water retention capacity, and 2) to ...
