The CERCHAR abrasivity test is very popular for determination of rock abrasivity. An accurate estimation of the CERCHAR abrasivity index (CAI) is useful for excavation operation costs. This paper presents a model to calculate CAI based on the gene expression programming (GEP) approach. This model is trained and tested based on a database collected from the experimental results available in the ...

The detailed distribution of Gammarus duebeni in freshwater habitats is discussed by Hynes (1954) and Sutcliffe (1967a). It occurs in a number of isolated coastal localities situated on the western sea-boards of Britain, including the Isle of Man, and on the Shetlands, the Faroes, Iceland, Norway and Brittany. In most of these localities the amphipod is restricted to only a few of the streams a...

The construction of bridges and other structures across the river will affect flood discharge capacity local water potential river.Based on navier-Stokes equation MIKE21FM hydrodynamic module, this paper carries out two-dimensional numerical simulation part Shixi River. By optimizing grid near piers to reduce difference brought by terrain generalized real river, it simulates analyzes length cur...

This article outlines the participation of the Documents and Linguistic Technology (DLT) Group in the Cross Language French-English Question Answering Task of the Cross Language Evaluation Forum (CLEF). Following our experiences last year (Sutcliffe, Gabbay and O'Gorman, 2003), our aim was to improve the system particularly in the early stages of processing, and to make further refinements to o...

Suspended sediment load (SSL) prediction study is critical to water resource management. This paper presents studies related the of SSL using machine learning (ML) algorithms over last 13 years. research gives a survey current that are used techniques predict on several rivers in different reign. Also, it aims find performance model SSL. done by making comparisons between time scales. Several m...
