Novel Genetic Algorithm (GA) based hybrid machine learning-pedotransfer Function (ML-PTF) for prediction of spatial pattern of saturated hydraulic conductivity

نویسندگان

چکیده

Saturated hydraulic conductivity (Ks) is an important soil characteristic that controls water moves through the soil. On other hand, its measurement difficult, time-consuming, and expensive; hence Pedotransfer Functions (PTFs) are commonly used for estimation. Despite significant development over years, PTFs showed poor performance in predicting Ks. Using Genetic Algorithm (GA), two hybrid Machine Learning based (ML-PTF), i.e. a combination of GA with Multilayer Perceptron (MLP-GA) Support Vector (SVM-GA), were proposed this study. We compared performances four machine learning algorithms different sets predictors. The predictor containing sand, clay, Field Capacity, Wilting Point highest accuracy all ML-PTFs. Among ML-PTFs, SVM-GA algorithm outperformed rest PTFs. It was noticed PTF demonstrated higher efficiency than MLP-GA algorithm. reference model prediction selected as paired K-5 variables. 160 models from past literature. found advocated improvement these current would help efficient spatio-temporal using pre-available databases.

Scale-Dependent Pedotransfer Functions Reliability for Estimating Saturated Hydraulic Conductivity

Saturated hydraulic conductivity Ksat is a fundamental characteristic in modeling flow and contaminant transport in soils and sediments. Therefore, many models have been developed to estimate Ksat from easily measureable parameters, such as textural properties, bulk density, etc. However, Ksat is not only affected by textural and structural characteristics, but also by sample dimensions e.g., i...
