The Davo River, an affluent of the Sassandra like other rivers in Côte d’Ivoire, is subject to anthropogenic activities likely deteriorate its quality which could affect use as drinking water and also health aquatic organisms. This study aims at monitoring temporal evolution physico-chemical waters River Dakpadou hydrometric station. Twelve monthly field missions were carried out sample water, ...

This study investigates the applicability of Satellite Precipitation Products (SPPs) in near real-time for simulation sub-daily runoff Vilcanota River basin, located southeastern Andes Peru. The data from rain gauge stations are used to evaluate quality Integrated Multi-satellite Retrievals GPM–Early (IMERG-E), Global Mapping Precipitation–Near Real-Time (GSMaP-NRT), Climate Prediction Center M...

The purpose of this study is to assess the ability of the artificial neural network (ANN) models in estimating river ice thickness using easy available climate data. A site specific ANN models were developed for two hydrometric stations at two rivers in Alberta (Canada). The ANN models were found to adequately estimate ice thickness. Ways to improve the performances of the ANN models are proposed.

This study used the standardized precipitation index (SPI) and runoff (SRI) to analyze dry humid conditions in hill-country catchment area of Laborec River (Slovakia) over a period 50 years (1970–2019). Analysis SPI SRI various time scales showed occurrence wet periods (index > 1.0) that were associated with exceeding long-term norm, below −1.0), which result small amounts precipitation. cor...

In Algeria, only the transport of suspended sediment is measured, rate bedload in global solids estimated, approximately. Measures bed load field are very costly, due to flow disturbances. As a result, evaluations this type difficult carry out absence databases. article, we tried quantify mode at wadi El-Hammam using formula Meyer-Peter and Müller. Formula that seems best adapted physical chara...

Constructing of control structures, like dams, change temporal and spatial unequal distribution of water ,and also play an effective role in reduce or eliminate of damage that caused by floods. So reservoir dam’s effect on floods discharges reduction must be determined. In this study the rain Information and flood hydrographs were used to check the flood routing for previous period of Maroon da...

in this study, several data-driven techniques including system identification, adaptive neuro-fuzzy inference system (anfis), artificial neural network (ann) and wavelet-artificial neural network (wavelet-ann) models were applied to model rainfall-runoff (rr) relationship. for this purpose, the daily stream flow time series of hydrometric station of hajighoshan on gorgan river and the daily rai...
