Yeah. A little runoff.

leading to increased runoff and evaporation.

We've got some runoff from a sewage plant farm.

Naturally, when you divert water, there's a little runoff.

So every one of our schools has a rainwater collection system.

Very low cost three classrooms and rainwater collection is 5,000 dollars.

And it can collect six million gallons of rainwater in one season.

And all the rainwater that drops on the Mountain is actually accumulated.

Looks like he was washed down the entire length of the runoff channel.

Do they, for instance, capture rainwater so that we can reduce water use?

like petrochemicals and like fertilizer runoff into the price of a bag of chips.

There's irrigation in the valley, and there's always a little runoff after they do that.

Here's a design for harvesting rainwater that's super cheap and available to people in the developing world.

If we have four years of drought, we still have water on the campus, because we collect rainwater.

Their spending loads, loads, to channel that rainwater out into the ocean when it rains and floods as well.

Another important point of these sand banks is that when it rains, the rainwater soaks down into the soil.

We then dug a big hole to put in a rainwater catchment tank to take our yard water independent.

Barefoot technology this was 1986 no engineer, no architect thought of it but we are collecting rainwater from the roofs.

It's a river that carries with it all the things that rivers tend to carry these days chemical contaminants, pesticide runoff.

So this rainwater is flooding down the hillside, carrying with it sediments from the construction site, smothering the coral and killing it.

Economic expansion has resulted in increases in atmospheric nitrous oxide and methane, ozone depletion, increases in great floods, damage to ocean ecosystems, including nitrogen runoff,

The roofs not only temper urban heat island impact but they save energy, and therefore money, the emissions that cause climate change, and they also reduce stormwater runoff.

Or, if you want to paint, you can paint it blue throughout because every roof which you see in this picture collects rainwater drops and deposit in the rooms.

So, look at the beauty from the desert society who can harvest rainwater, and also create something through a tire from a jet plane, and used in a camel cart.

There's a company making a product called Lotusan, which mimics when the building facade paint dries, it mimics the bumps in a self cleaning leaf, and rainwater cleans the building.

Do they, perhaps, include green infrastructure, so that we can take runoff and water that's going out of our houses and clean it and filter it and grow urban street trees?

That the aerosols can at least in these models, simulations, or indicated by these simulations can offset most climate change in most places most of the time for both precipitation and runoff.

As evident in this slide from Lake Nabugabo in Uganda, the agricultural runoff from this crop, which goes into these buckets, is the sole source of drinking, cooking and bathing water for this village.

In addition to, I think, doing a beautiful adaptive reuse, they tore up some of the parking spaces, put in bioswales to collect and clean the runoff, put in a lot more sidewalks to connect to the neighborhoods.

Porous asphalt, a material that we use now in most of the highways in the Netherlands, it has pores and water can just rain through it, so all the rainwater will flow away to the sides, and you have a road that's easy to drive on, so no splash water anymore.
