07/18/08 We have a 15 x 30 foot pool, approximately 17,000 gallons. Had green algae on the steps, bottom and sides after being away for about 2 weeks. The water was still clear but had some green slime floating also. Ugh!!! I did some online research and then took a sample to my local pool store (they provide a water container for samples). Take in about 2 cups, fill it about 1 foot down from the top of pool. To clear it up this is what the local pool store sold to me and told me what to do, along with some hints I got online, and it worked: They sold me two gallons of murietic acid and 2 packets of superchlorinator. I only used 3/4 of a gallon of the acid, and I used both packets of the superchlorinator. 1. Sweep the pool, sides, bottom, steps, etc to loosen the algae. Remove the vacuum cleaner - I was told the the algaeside will scar/eat away at the wheel runners. 2. Turn the filter on - keep it on throughout the whole process - 24 hours. 3. Add the algaecide (muriatic acid) 4 cups every three hours for a total of three times. I started at 7 am - do this during the day, not at night. So at 7 am, 11 am and 3 pm I added 4 cups each time of the myuretic acid - BE EXTREMELY CAREFUL WITH THIS STUFF - IT IS POISON - IT SMOKES AS YOU POUR IT - DON'T BREATH THE FUMES - WITH THE CAP OFF I WALKED THRU A CLOUD OF IT WHILE I WAS POURING IT INTO THE POOL - IT BURNS, READ THE DIRECTIONS BEFORE YOU START - ITS NASTY DANGEROUS STUFF. I used a paper cup to pour it in so I could throw it away. 4. Four hours after the last pour of the algaecide, I opened the two bags of the superchlorinator they gave me (it appeared to be a chlorine powder), the bags were about 2 cups each, poured these into a bucket of water (some online directions said NEVER ADD WATER TO THE CHLORINATOR, ALWAYS ADD THE CHLORINATOR TO WATER.) 5. Empty the bucket of water with the chlorinator into the pool. 6. Keep the filter running the entire time you do all this - 24 hours so the stuff can circulate throughout your pool. 7. After another four to six hours, put your vacuum back into the pool and start vacuuming. 8. Check and clean the filter every once in awhile. It's now about 8 am the day after I started, I just plugged the vacuum in and got it going. A lot of the algae is gone, WOW! It looks like I'll need to sweep it a couple more times just to stir up the dead algae so the filter can suck it out. But it worked great! Online info says we can use the pool anytime now (it's been 24 hours since I started). But I think I'll wait another 24 hours. Maybe other people have better ways to clean up the algae - this was kind of scary because of the murietic acid, but it worked. Good luck - you can do it!
Minnows can be carried into a dry ditch after it rains when the rainwater floods the surrounding area, allowing them to swim into the ditch. They may also be transported there by birds or other animals that can carry them in their feathers or fur from other water sources.
A canion.
Waterbar : a shallow ditch excavated across a road at an angle to prevent excesssurface flow down the road surface and subsequent erosion of road surface materials. Asmall excavation across a road to collect and divert roadway surface water flow.
To fix erosion in a ditch, you can plant erosion-resistant plants, install erosion control materials like geotextiles or riprap, or shape the ditch with stone or vegetation to slow down water flow and prevent further erosion. Regularly maintaining these erosion control measures is crucial to ensure long-term effectiveness. Consider seeking advice from a landscaping professional for a tailored solution.
Another word for a hole in the ground is a pit or a cavity.
Not if it is a drainage ditch that affects anyone else but you, or if it is a designated wetland area.
you can drink it, but it depend if it is clear.
A steel grate cover for a drainage ditch can be found at an industrial supply store. They are generally purchased by contractors for maintenance and installation jobs.
a drainage ditch, and aquaduct, i think.

That's highly unlikely unless the well is very shallow.
The Purpose of a Drainage Ditch was the bottom of the trenches where the soil turned very muddy. It held the muddy water, rubbish and occasionally excretement and stopped the soldiers from stepping on it with Duckboards.
One word that fits this definition is ditch.
Anything, and i know what i'm saying, i'm portuguese. That word seems german.
A gully is a water-worn ravine or small valley, often caused by erosion from heavy rain or flooding. A ditch, on the other hand, is a man-made trench dug to channel water or provide drainage. While both can be used to manage water flow, gullies typically form naturally, whereas ditches are constructed by people.
" Step 1 Dig out the drainage ditch. Broaden the ditch to roughly twice the width of the culvert and angle the sides of the ditch. Dig about six inches out of the bottom, for the entire length of the culvert. Step 2 Fill the bottom six inches with gravel, maintaining the original level of the drainage ditch. The gravel will allow the culvert to settle evenly and allow for better drainage in the event that water flows around the culvert. Step 3 Place the culvert in the ditch, centering it in the gravel. There should be about one foot of excess length on each end of the culvert. Step 4 Fill in the sides next to the culvert with dirt, tamping the dirt down at regular intervals. Keep the culvert centered in the ditch while doing this; a crooked culvert will cause erosion on the walls of the ditch. Step 5 Cover the top of the culvert. Cover with at least 12 inches of dirt and tamp down well. Cover this with gravel to avoid erosion. Step 6 Tamp the sides of the fill down tightly, making sure they are angled in towards the top. Regular maintenance will be needed to keep the walls from eroding away." and that how u install it
Many highway departments use crown vetch along steep hillsides.
