The Material Properties dialog allows for the description of the material under consideration. The primary purpose of the Material Dialog is to store the original properties of the material.

 

General Tab

The General tab contains information specific to the in situ state of the soil. General information such as the land use as well as specific fields relating to the soil strata from which the soil was sampled can be entered. The depth from which the sample was taken is also relevant to determining the location of the current soil sample.

 

Material Name:The Material Name field displays the name of the soil.

 

Sample Date:The Sample Date field allows the user to enter the date when the soil sample was taken.

 

Classification:The Classification field allows the user to select the soil classification system to be used.

 

Units:The Units field shows the system of measurements being used. The system of units for the soil cannot be changed once it has been selected.

 

Saturated only analysis:The Saturated only analysis checkbox allows the user to select whether or not the soil was in saturated state when sampled. If the soil was sampled in an unsaturated state, then additional options will appear for determining unsaturated properties.

 

Soil Feature:Select Compacted, Remoulded or Undisturbed. Compaction refers to the process of driving air from the soil when the water content is near to the plastic limit of the soil. Remoulding refers to the process of “reworking” the soil near to its liquid limit for its original state prior to testing.

 

Sampling Depth:The Sampling Depth field allows the user to enter the depth below ground surface from which the soil sample was taken.

 

Specific Gravity:The Specific Gravity field allows the user to enter the specific gravity of the soil sample.

 

Volume-Mass State:Details on the Volume-Mass state can be found here.

 

Description Tab

The Description Tab is used to provide a description of the soil.

 

Project and Station Tab

The Project and Station tab is used to describe the location from which the soil sample was taken. The fields are intended to describe a general location. A specific location (referenced to a GIS system) can be entered when the New Station button is selected. The default project ID and name is shown in their respective fields.

 

To add information on the sample station, select New Station.

 

Publisher Tab

The Publisher tab contains fields necessary for identifying the publication in which the current soil originated. Many of the soils included in the SVSOILS database have been digitized from data presented in conference and journal publications. Where possible, the reference information has been included in the SVSOILS database. The publisher information is useful because it allows the user to search for data relating to a certain publication.

 

Constants Tab

The Constants tab lists global constants which default to standard values. The user can adjust these global constants for unusual cases but the default values are adequate for most analysis.
