YHWH

Based on the writing style this part is likely a later addition:20And Noah began to be an husbandman, and he planted a vineyard:21And he drank of the wine, and was drunken; and he was uncovered within his tent.22And Ham, the father of Canaan, saw the nakedness of his father, and told his two brothers without.23And Shem and Japheth took a garment, and laid it upon both their shoulders, and went backward, and covered the nakedness of their father; and their faces were backward, and they saw not their father's nakedness.24And Noah awoke from his wine, and knew what his younger son had done unto him.25And he said, Cursed be Canaan; a servant of servants shall he be unto his brothers.26And he said, Blessed be Yahweh of Elohim of Shem; and Canaan shall be his servant.27God shall enlarge Japheth, and he shall dwell in the tents of Shem; and Canaan shall be his servant.

5And the waters decreased continually until the 10th month: in the 10th month, on the 1st day of the month, were the tops of the mountains seen.6And it came to pass at the end of 40 days, that Noah opened the window of the ark which he had made:7And he sent forth a raven, which moved around until the waters were dried up from off the earth.8Also he sent forth a dove from him, to see if the waters were abated from off the face of the ground;9But the dove found no rest for the sole of her foot, and she returned unto him into the ark, for the waters were on the face of the whole earth: then he put forth his hand, and took her, and pulled her in unto him into the ark.10And he stayed yet other 7 days; and again he sent forth the dove out of the ark;11And the dove came in to him in the evening; and, lo, in her mouth was an olive leaf pluckt off: so Noah knew that the waters were abated from off the earth.12And he stayed yet other 7 days; and sent forth the dove; which returned not again unto him any more.13And it came to pass 601 years, in the first month, the first day of the month, the waters were dried up from off the earth: and Noah removed the covering of the ark, and looked, and, behold, the face of the ground was dry.14And in the 2nd month, on the 27th day of the month, was the earth dried.15And God spake unto Noah, saying,16Go forth of the ark, you, and your wife, and your sons, and your sons' wives with you.17Bring forth with you every living thing that is with you, of all (pure?) flesh, both of fowl, and of cattle, and of every creeping thing that creepeth upon the earth; that they may breed abundantly in the earth, and be fruitful, and multiply upon the earth.18And Noah went forth, and his sons, and his wife, and his sons' wives with him:19Every beast, every creeping thing, and every fowl, and whatsoever creepeth upon the earth, after their kinds, went forth out of the ark.20And Noah builded an altar unto Yahweh Elohim; and took of every clean beast, and of every clean fowl, and offered burnt offerings on the altar.21And Yahwey Elohim smelled a sweet savour; and Yahwey Elohim said in his heart, I will not again curse the ground any more for man's sake; for the imagination of man's heart is evil from his youth; neither will I again smite any more every thing living, as I have done.22While the earth remaineth, seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease.

1And it came to pass, when human began to multiply on the face of the earth, and daughters were born unto them,2That the sons of the Elohim saw the daughters of human that they were fair; and they took them wives of all which they chose.3And Yahweh (or Enki) of Elohim said, My appearance shall not always strive with humans, for that he also is flesh: yet his days shall be limited to 120 years.4There were giants in the earth in those days; and also after that, when the sons of the Elohim came in unto the daughters of human, and they bare children to them, the same became mighty human which were of old, human of renown5And Elohim saw that the rebellion of humans was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.6And it repented the LORD that he had made humans on the earth, and it grieved him at his heart.7And the LORD said, I will destroy altered humans whom I have created from the face of the earth; both altered humans, and altered beast, and the altered creeping thing, and the altered fowls of the air; for it repenteth me that I have made them.8But Noah found grace in the eyes of the LORD.9These are the generations of Noah: Noah was a just altered human and perfect in his generations, and Noah walked with God.

29and he called his name Noah, saying, This same shall comfort us concerning our work and toil of our hands, because of the ground which Elohim YHWH hath cursed. 

In Genesis 2:4, YHWH Elohiym acquired the earth (En).

See Genesis 2: YHWH Created Hybrids in Mesopotamia

And in the day that the YHWH Elohiym acquired the earth and the atmosphere,

5the plants were not yet in cultivated fields in the land, and herbs were not yet grown under controlled conditions because the YHWH Elohiym had not caused it to rain on the land, and humans were not made servants to till the ground.

8And the YHWH Elohiym established an enclosed garden eastward in Eden; and there they put the humans whom they had predetermined.

9And among the land the YHWH Elohiym brought forth all the trees that were pleasant in appearance, and good for food; the trees that were alive.

Alternative translation:“And YHWH Elohim planted a protected space in Eden, from the origin, and placed there the human whom He had formed.”

Were instead of Elohim, God for English translations, changes to Yahweh (Elohim), the Lord God in English translations.
