Jalapradanika Parva is the eighty fourth Upa parva included in the eleventh Maha parva named as Stri parva. Vaishampayana continued narration to Janamejaya in reply to his queries as follows.
What was the main difference between Shraddha and Jalapradanika Parvas?
The contents of Shraddha parva dealt with the dead bodies in the funerals using fire by only the male livings people of the kings and soldiers of the war. The contents of Jalapradanika parva described the offering of water oblations in honor of the dead, on the banks of river Ganga using the holy water, by all the livings people of the kings and soldiers of the war.
The fire flames usually show, burning upward, symbolizing the soul entering in to the heaven. The water oblations usually show, pouring downward, symbolizing the physical remains entering in to the permanent earth. Then, the heart and body get purified gradually.
On the side of the Kauravas army, who was alive and authorized to perform the water offering rituals after the war?
Yuyutsu was the youngest of the Kauravas alive after the Mahabharata war on the side of Kauravas and he was authorized for the water offering rituals. He was very sympathetic. He had protested Dushasana in the court, while the dice game was played between Duryodhana and Yudhistira. He supported righteousness, frequently referring the phrase ॥ यतो धर्मस्ततो जयः ॥.
Before the commencement of the war, an option to accept the sides was provided by Yudhishtira, and Yuyutsu had entered the side of the Pandavas army. Please refer Bhishma Patana parva of this website.
It was Yuyutsu who initially named Yudhishtira as Dharmaraja. Yuyutsu had later ruled in Indraprastha, and helped Yudhishitra with his Ashwamedha yaga also.

Who was the mother of Yuyutsu? What happened to the land he ruled later?
The maid servant of Gandhari, named as Sugadha, was the mother of Yuyutsu. Dritarashtra was his father. He had ruled Indraprastha and got natural death. He had lived for one hundred and twenty years of age and after his death, the land he ruled was amalgamated with the land of king Parikshit of Hastinavati.
