bedload transport predictions based on field measurement data by combination of artificial neural network and genetic programming

چکیده
bedload transport is an essential component of river dynamics and estimation of its rate is important to many aspects of river management. in this study, measured bedload by helley- smith sampler was used to estimate the bedload transport of kurau river in malaysia. an artificial neural network, genetic programming and a combination of genetic programming and a neural network were used to estimate the bedload carried in kurau river, based on bedload transport measurement data and hydraulic variables. a statistical analysis was carried out to validate methods by computing rmse, mare and inequality ratio (u). in general, the ability of the artificial neural network combined with genetic programming with r2 equal to 0.95, rmse equal to 0.1 as a precipitation predictive tool for predicting the bedload transport rate was observed as being acceptable.

today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...
Estimating Efficiency of Bank Branches by Dynamic Network Data Envelopment Analysis and Artificial Neural Network
Network data envelopment analysis models assess efficiency of decision-making unit and its sections using historical data but fail to measure efficiency of its units and their internal stages in the future. In this paper we aim to measure efficiency of stages of bank branches and obtain efficiency trend of stages during the time, then to estimate their efficiency in the future therefore we can ...
