The area of land around buildings should be formed so that any surface water in the immediate surroundings (extending at an absolute minimum of 0.5m (20") beyond the building) is directed away from the building. This can be done by sloping the land at at least 1 in 50/2%/1.15 degrees or more, or by having drainage channels around the perimeter. (Check local authority regulations.)
The water diverted away from the immediate surrounds of the building by slopes or drains then needs to be able to flow away further so that it does not back up to the building. Swales, drains and slopes can all achieve this.
A swale is a wide concave vegetated channel that allows slow surface flow of water and also allows the water to soak gradually into the soil, reducing the chance of a large peak flow of water, and recharging the water table. The vegetation must be maintained to ensure water can flow through the swale, and the swale will need to carry any water beyond the capacity it can immediately absorb to a stormwater system or waterway.
I don't think you want to do this! It could be accomplished with berms and swales to channel the water; but having the drainage go towards the house isn't done--is this house in Death Valley or something?
Some effective drainage solutions for yards include installing French drains, creating swales or berms, adding dry wells, and improving soil grading to direct water away from the property.

Both swells and swales can be plural nouns.Swells are large waves. Swales are dips or valleys in the ground.The word swells can also be a verb (to swell), meaning to grow in size or metaphorically so.Examples:Water can accumulate in roadside swales after a heavy rain.The ocean swells reached 22 feet in height.Swells of water overwhelmed the small sailboat.The skin often swells temporarily after a tattoo is done.My heart swells with pride when I think of my disabled son's accomplishments.
A combination of topographic analysis using digital elevation models (DEMs) and hydrological modeling can help identify natural drainage swales in the desert that are prone to flash flooding. DEMs can reveal the terrain's slope and elevation variations, while hydrological modeling can simulate water flow and identify areas where water is likely to accumulate during flash flooding events. Field verification may also be necessary to confirm the presence of natural drainage swales.

Some effective residential drainage solutions for managing water flow around a property include installing French drains, grading the land to direct water away from the house, using gutter systems to collect and divert rainwater, and creating swales or dry creek beds to channel water runoff.
To address a drainage problem effectively, steps can include identifying the cause of the issue, improving soil permeability, installing proper drainage systems such as French drains or swales, and regularly maintaining and cleaning the drainage system to prevent blockages. Consulting with a professional landscaper or engineer may also be helpful in finding the best solution for the specific drainage problem.
