Finding dependencies on a SPECIFIC COLUMN (modern way, without using sysdepends)
Here is an AdventureWorks example on viewing column dependencies.

SELECT ReferencingObject = SCHEMA_NAME(o1.schema_id) + '.' + o1.name,
       ReferencedObject = SCHEMA_NAME(o2.schema_id) + '.'
                          + ed.referenced_entity_name,
       ColumnName = c.name,
       ReferencedObjectType = o2.type,
       ReferencingObjecType = o1.type
FROM   AdventureWorks2012.sys.sql_expression_dependencies ed
       INNER JOIN AdventureWorks2012.sys.objects o1
               ON ed.referencing_id = o1.object_id
       INNER JOIN AdventureWorks2012.sys.objects o2
               ON ed.referenced_id = o2.object_id
       INNER JOIN AdventureWorks2012.sys.sql_dependencies d
               ON ed.referencing_id = d.object_id
                  AND d.referenced_major_id = ed.referenced_id
       INNER JOIN sys.columns c
               ON c.object_id = ed.referenced_id
                  AND d.referenced_minor_id = c.column_id
WHERE  SCHEMA_NAME(o1.schema_id) + '.' + o1.name = 'HumanResources.vEmployee' AND c.name = 'JobTitle'
ORDER  BY ReferencedObject,
          c.column_id;
