Abstract The paper presents the possibility of using data mining tools — artificial neural networks in prediction hydrometer reading after 24 h order to limit duration test 4 h. authors analysed a database 693 granulometric composition analysis results genetically different soils with use radial basis function network (RBF) and multilayer perceptron (MLP). calculations performed showed that it ...

Several empirical methods for flood flow rate estimation have been presented. In this study,eight new empirical runoff estimation method including Dredge & Burge, Bourges, Inglis, Faning, Hyderabad, Burkli Ziegler, Cramar and Possenti were calculated in Bakhtegan watershed which is located in Fars province. After studying empirical methods for annual flood flow rate estimation and comparing the...

Abstract Ecosystem services do not exist independently from human perceptions and recognition. They are socially, culturally, economically, environmentally scale- context-dependent. Socio-cultural tend to be difficult evaluate invisible policymakers conservation practitioners. Based on six years’ qualitative analysis of a floodplain fishery in the Pantanal wetland, Brazil, we bring an in-depth ...

Abstract This study presents a method to determine the operation of measuring equipment by analyzing metrological quality and degradation accuracy, depending on accumulated volume installation time. Different types counters at three flow rates were tested assess evolution relative error average curves rate deterioration. The apparent losses caused inaccuracies meters was also calculated. result...

Simulation of the runoff-rainfall process in forest lands is essential for land management. In this research, a hydrologic modelling system (HEC-HMS) and artificial neural network (ANN) were applied to simulate rainfall-runoff (RRP) Kasilian watershed with an area 68 square kilometres. The HMS model was performed using secondary data rainfall discharge at climatology hydrometric stations, Soil ...

This article presents six probability distributions from the gamma family with three parameters for flood frequency analysis in hydrology. The choice of statistical was driven by its frequent use In Faculty Hydrotechnics, improvement estimation maximum flows, including methodological bases realization a regionalization study linear moments method corrected parameters, researched and is an eleme...

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...
