Here is a good link for you about water retention:

What Is Water Retention (Fluid Retention)? What Causes Water Retention?

http://www.medicalnewstoday.com/articles/187978.php

A couple of other thoughts:
1) Your water retention can be caused by chemo, but it can also be caused by other things such as heart or kidney disease. If this is persisting, I would get a good physical with my primary care provider.
2) After chemo, we are all usually whipped out. But being sedentary will make things worse. It can actually cause fluid retention, so you can get into a vicious cylcle. Try and get up and take short walks frequently. Build slowly each day.
3) If you really can't walk, move your arms and legs while sitting. Flex your calf muscles and wiggle your feet forward and back. Pretend step on your tiptoes and then put your foot flat again while sitting. The blood in your veins (especially in your legs) is not actively pumped--to get the blood back to your heart, your body depends on muscle contractions. Anotherwords, you have to move it to lose it ;-).
4) As Doris mentioned, use pillows to raise your arms and legs to help gravity assist your body.

And here are more tips from chemocare:

Things you can do to manage swelling:
•Elevate your feet as often as possible. (Either sitting in a chair with your feet on a stool with a pillow or in the bed or couch with feet up on two pillows)
•Do not stand for long periods of time.
•Avoid tight clothing (shoes, girdles, etc).
•Do not cross your legs.
•Reduce your salt intake if swelling is present. Avoid foods such as bouillon, potato chips, tomato juice, bacon, ham, canned soups, soy sauce, and table salt, for example.
•Try to eat a balanced diet (see eating well section).
•If your swelling is severe, consider wearing Jobst stockings or TED hose.
•Weigh yourself daily. Notify your doctor or health care provider if you have gained 5 pounds or more in a week.
•Take your medications exactly as prescribed.
