    For clean sands (less than 5% passing the No. 200 sieve), the classification is well-graded sand (SW) if C ≥ 6 and 1 Cc 3. Both of these criteria must be met for the soil to be SW, otherwise the classification is poorly graded sand (SP). Clean gravels (less than 5% passing the No. 200 sieve) are classified as well-graded gravel (GW) if
