Erosividade das chuvas em Uruguaiana, RS, determinada pelo índice EI30, com base no período de 1963 a 1991 Rainfall erosivity in Uruguaiana, Rio Grande do Sul, Brazil from 1963 to 1991 determined by the EI30 index

open access: yesRevista Brasileira de Ciência do Solo, 2008
A erosividade representa o potencial que as chuvas têm de provocar erosão hídrica no solo. O índice EI30 é um método de determinação dessa erosividade das chuvas e é calculado, para cada chuva individual e erosiva, pelo produto da energia cinética total ...

Exploring controls on rainfall–runoff events: spatial dynamics of event runoff coefficients in Iran

open access: yesHydrological Sciences Journal, 2023
This study investigates the controls that influence the spatial variability of event runoff coefficients (RCs) based on the comparative hydrology concept. We analysed 18 468 storm events in 963 Iranian catchments ranging in size from 101 to 8467 km2. The mean RCs vary spatially due to long-term hydro-climate conditions and other catchment descriptors ...

Effects of land uses and rainfall regimes on surface runoff and sediment yield in a nested watershed of the Loess Plateau, China

open access: yesJournal of Hydrology: Regional Studies, 2022
Study region: The Loess Plateau, China. Study focus: Land-use and rainfall characteristics are two crucial influencing factors that affect the surface runoff and soil loss process; however, less attention has been paid to nested watersheds in vulnerable ...

Correcting the radar rainfall forcing of a hydrological model with data assimilation: application to flood forecasting in the Lez Catchment in Southern France [PDF]

open access: yes, 2012
The present study explores the application of a data assimilation (DA) procedure to correct the radar rain- fall inputs of an event-based, distributed, parsimonious hy- drological model.

An Evaluation of the Accordance of Modified TRMM Satellite Precipitation Data with Observational Data in the Shapour Basin in the Fars Province [PDF]

open access: yesپژوهش‌های آبخیزداری, 2018
Precipitation is one of the main components of the hydrological cycle, and its data are required for the analysis of meteorological and hydrological models. Due to lack of rainfall data in spatial and temporal scales, this study was performed to evaluate

Evaluation and application of multi-source satellite rainfall product CHIRPS to assess spatio-temporal rainfall variability on data-sparse Western margins of Ethiopian Highlands [PDF]

open access: yes, 2019
The spatio-temporal characteristic of rainfall in the Beles Basin of Ethiopia is poorly understood, mainly due to lack of data. With recent advances in remote sensing, satellite derived rainfall products have become alternative sources of rainfall data ...

A variable storage coefficient model for rainfall—runoff computation / Modèle pluie—débit basé sur un coefficient de stockage variable [PDF]

open access: yesHydrological Sciences Journal, 2008
Abstract The study explores the suitability of a two-reservoir variable storage coefficient (2VSC) model with respect to the popular two-parameter gamma distribution (2PGD) model (Nash, 1957) for direct runoff hydrograph (DRH) derivation from a small test catchment.

Rainfall-Runoff Analysis using Runoff Coefficient and SCS-CN Methods under GIS Approach

open access: yesInternational Journal of Environment and Climate Change, 2021
Estimation of runoff in a watershed is very important to manage the water resources efficiently. In this regard, surface runoff quantification is an essential study. The main objective of this study is to quantify the surface runoff of the catchment area of a well located in AEC & RI, TNAU, Kumulur, Trichy District of Tamil Nadu State, India.

Predicting floods in a large karst river basin by coupling PERSIANN-CCS QPEs with a physically based distributed hydrological model [PDF]

open access: yes, 2019
In general, there are no long-term meteorological or hydrological data available for karst river basins. The lack of rainfall data is a great challenge that hinders the development of hydrological models. Quantitative precipitation estimates (QPEs) based
