Soil genesis and classification
a r t i c l e i n f o Keywords: Pedology Soil genesis Soil history Soil taxonomy Soil science in the USA The formation and classification of soils have been a key area of research in the soil science discipline. Major breakthroughs have been brought about since the mid 1800s and it has evolved from conceptual frameworks, to descriptive studies to more quantitative approaches. Some 50 years ago ...
متن کاملSoil Classification Using GATree
This paper details the application of a genetic programming framework for classification of decision tree of Soil data to classify soil texture. The database contains measurements of soil profile data. We have applied GATree for generating classification decision tree. GATree is a decision tree builder that is based on Genetic Algorithms (GAs). The idea behind it is rather simple but powerful. ...
متن کاملSoil Classification Through Penetration Tests
The Newcastle Dilatometer (NDMT) developed by Akbar in 2001 has a distinctive feature that it loads the soil with a rigid piston in place of flexible membrane as in the Marchetti Dilatometer (MDMT). Based on the previous research works carried out using the NDMT in normally consolidated soils, it has been found that the material and dilatometer indices from the NDMT data can be used to classify...
متن کاملPhysiography, Geology, and Soil Classification
Young’s Branch (YB), located on a portion of the Wayne National Forest in Lawrence County, is located on bedrocks belonging to the Allegheny group. By contrast, Bluegrass Ridge (BR), the other study area in Lawrence County, is underlain by sedimentary strata of the Connemaugh group. The bedrock complex includes a combination of sandstones, sandy shales (or siltstones), and clay shales (Denton e...
متن کاملReview and Classification of Modeling Approaches of Soil Hydrology Processes
To use soil hydrology processe (SHP) models, which have increasingly extended during the last years, comprehensive knowledge about these models and their modeling approaches seems to be necessary. The modeling approaches can be categorized as either classical or non-classical. Classical approaches mainly model the SHP through solving the general unsaturated flow (Richards) equation, numerically...
