What is drainage in golf?
Drainage is a fundamental piece of golf course architecture. If a course doesn’t drain well it will rarely play well. Therefore, figuring out how to move water off the golf course is a golf course architect’s primary worry. There are two ways that an architect can move water; the natural land or through manmade drainage systems.
What type of soil is best for a golf course?
The best soil to build a golf course on is the sandy variety. Sandy soil allows shapers and construction crews to easily move and contour the ground to their desired specs. The sand also plays a pivotal role in drainage and playing conditions. Sandy soil drains better, allowing a golf course to play firm and fast on a more regular basis.

Why use a drainage basin?
One issue that arises with using drainage systems is the water tends to settle around the drain. This will create a softer area where grass doesn’t grow as quickly and firm conditions cease to exist.
What are the common scenarios for bunker sand?
Common Scenarios. 1. Selecting bunker sand for a wet climate. There is a paradox between selecting bunker sands that have a high enough infiltration rate to handle heavy rain events yet remain firm enough to encourage inbound golf balls to bounce from the impact point.
What is the difference between set up and crusting?
Calcareous sands – those that contain calcium carbonate – and bunker sand containing a combination of silt and clay that exceed 3% are more prone to crusting or set-up. Crusting is a thin layer of hardened sand that forms at the sand surface, while set-up is a layer of hardened sand beneath the surface, both of which may develop during drying cycles. The crusting potential test is performed by spreading a thin layer of sand in a tray, adding a small amount of water, allowing the sand to dry, then inserting a thin spatula in the sand and lifting to observe if a crusted layer formed during the drying process. The set-up test is slightly different and involves scraping off the surface layer of the sand and observing if a cemented layer has formed on the bottom of the tray.
What are the characteristics of bunker sand?
There are nine key bunker sand characteristics that can be tested in a laboratory: particle size distribution, particle shape, coefficient of uniformity , angle of repose, penetrometer reading, infiltration rate, crusting potential, chemical reaction and color. The soil moisture release curve (SMRC) and moisture column tests will also be discussed. The following text will summarize these characteristics and how they are tested, and offer new perspectives based on current challenges observed in the field.
How many bunker sands were collected in 1985?
1. Particle size. In 1985 and 1986, USGA agronomists cooperated with golf courses across the United States to assess bunker sand quality and collected a total of 42 bunker sands for laboratory testing.
How much infiltration is needed for bunker sand?
The physical soil testing laboratory community has suggested that the minimum infiltration rate for bunker sand is 20 inches per hour, which was based on the 20-24 inch per hour infiltration rate guideline in the 1993 USGA Recommendations for a Method of Putting Green Construction. However, in my experience testing bunker sands on golf courses, I’ve seen that infiltration rates often decrease significantly – e.g., from 22.8 to only 7.5 inches per hour – in just two to three years! Silt and clay from wind-blown dust, organic debris from clippings, leaves from trees or shrubs, algae growth and soil contamination all can decrease infiltration rates. Bunker sands that initially drain from 30-100 inches per hour should work well, depending on the climate and site conditions.

How does core cultivation help with water infiltration?
Core cultivation (aeration) can resolve some waterinfiltration problems by reducing soil compaction,managing thatch, and creating openings in the turfsurface that aid in water infiltration . A reduction insoil bulk density of severely compacted soil willenhance water retention (storage) and encouragedeeper rooting, thus increasing the carrying capacityof the soil.
What are growth regulators?
Growth regulators reduce the need for mowing andmay be useful in reducing the need for irrigation.Greenhouse research has shown that some growthregulators (i.e., melfluidide, ethephon, andtrinexapacethyl) lower evapotranspiration, whichpotentially would extend the carrying capacity ofthe soil presuming adverse effects on root growthdo not occur with use of a growth regulator. Re-search has shown that growth regulators, other thanmelfluidide, can reduce rooting.
What is the term for the loss of water through evaporation from the soil surface?
Evapotranspiration (ET) is the term used to describethe loss of water through evaporation from the soilsurface and transpiration of water through plants.The rate of evapotranspiration (amount of water lostper day) is one of several factors that determine therequired frequency of irrigation for a given soil andplant system.
What time of day is the best time to water?
The most efficient time of day to water is late eveningthrough early morning (between 10 p.m. and 8 a.m.).Nighttime is generally less windy, cooler and morehumid, resulting in less evaporation and a moreefficient application of water. Water pressure is alsousually better at night resulting in a more uniformapplication of water through sprinklers. Contrary topopular belief, irrigating during this period does notstimulate disease development.
