In hydrology, run-on refers to surface runoff from an external area that flows on to an area of interest.
 A portion of run-on can infiltrate once it reaches the area of interest.
 Run-on is common in arid and semi-arid areas with patchy vegetation cover and short but intense thunderstorms.
 In these environments, surface runoff is usually generated by a failure of rainfall to infiltrate into the ground quickly enough (this runoff is termed infiltration excess overland flow).
 This is more likely to occur on bare soil, with low infiltration capacity.
 As runoff flows downslope, it may run-on to ground with higher infiltration capacity (such as beneath vegetation) and then infiltrate.
Sycamore Alluvial Woodland is a rare open woodland plant community, or vegetation type, dominated by California sycamore "Platanus racemosa", existing only in small parts of California.
 It exists only in small areas of California in the foothills of the southern Sierra Nevada range and the California Coastal Range.
 It is rare as a plant community, even though California sycamore is a common component of other vegetation types where it is not dominant.
 It exists at the base of flat valleys having deep alluvial gravel, where water from the hills hit the flat valley floor having an intermittent stream and large seasonal fluctuations in the water table.
British NVC community MG2 (Arrhenatherum elatius- Filipendula ulmaria tall-herb grassland) is one of the mesotrophic grassland communities in the British National Vegetation Classification system.
The brush-tailed rock-wallaby or small-eared rock-wallaby ("Petrogale penicillata") is a kind of wallaby, one of several rock-wallabies in the genus "Petrogale".
 It inhabits rock piles and cliff lines along the Great Dividing Range from about 100 km north-west of Brisbane to northern Victoria, in vegetation ranging from rainforest to dry sclerophyl forests.
 Populations have declined seriously in the south and west of its range, but it remains locally common in northern New South Wales and southern Queensland.
Aloinopsis is a genus of ice plants from South Africa.
Desert dry wash is a North American desert vegetation type (or biome) occurring in the flat bottoms of canyons and drainages that lack water at or near the surface most of the year, and are subject to periodic severe flooding events.
 Desert dry wash is contrasted with desert riparian vegetation, which occurs in desert canyons and drainages where there is year-round water at or near the surface.
 Plants must either be able to survive the severe flooding conditions or be able to reestablish themselves before the next flooding event.
 Some of these plants have evolved so that in order for their seeds to germinate, the seeds must be scarified or abraded by tumbling sand, gravel, and rocks during the flooding event.
 They must then quickly send down roots deep enough to be able to tap into deep underground water reserves, in order to survive the dry period after the flooding.
 Common dominant species of the desert dry wash include smoke tree ("Psorothamnus spinosus"), desert willow ("Chilopsis linearis"), catclaw ("Senegalia greggii"), cheesebush ("Ambrosia salsola"), and waterweed ("Baccharis sergiloides").
Rondebosch Common is an open common of about 40 ha in Rondebosch, Cape Town in South Africa.
 A common is defined as "A piece of open land for public use, esp.
 in a village or town."
 It contains one of the only surviving pockets of the critically endangered “Cape Flats Sand Fynbos” vegetation type, which exists nowhere else in the world.
Desert riparian is a North American desert vegetation type (or biome) occurring in the bottoms of canyons and drainages that have water at or near the surface most of the year.
 It is contrasted with the desert dry wash vegetation type in which water at or near the surface is lacking most of the year.
 The visual character is of large, lush green trees surrounded by dry desert vegetation and soil coloration.
 The area may be in a patch surrounding a spring (oasis), or in a strand following the course of water flow.
 Over 80% of known desert wildlife species use desert riparian areas.
 Common dominant species include Fremont cottonwood ("Populus fremontii"), Arizona ash ("Fraxinus velutina"), arroyo willow ("Salix lasiolepis"), Goodding's willow ("Salix gooddingii"), red willow ("Salix laevigata"), California fan palm ("Washingtonia filifera"), and invasive species such as salt cedar ("Tamarix ramosissima"), giant reed ("Arundo donax"), and Russian olive ("Elaeagnus angustifolia").
 Salt cedar is particularly causing problems for this ecosystem because it is able to extract water more efficiently than cottonwoods and willows.
 Many noninvasive non-native species may also be found because springs and surface water areas in the desert often were old homesites where such species were intentionally planted, such as elm, black locust, and assorted fruit trees.
Filipendula is a genus of 12 species of perennial herbaceous flowering plants in the family Rosaceae, native to the temperate regions of the Northern Hemisphere.
 Well-known species include meadowsweet ("Filipendula ulmaria") and dropwort ("Filipendula vulgaris"), both native to Europe, and queen-of-the-forest ("Filipendula occidentalis") and queen-of-the-prairie ("Filipendula rubra"), native to North America.
Istarske Toplice (Terme Istriane, o Bagni di Santo Stefano), a thermal health resort in the central part of Istria, Croatia.
 It's located in the village of Livade, 11 km southwest of Buzet (Pinguente).
 It is located in the canyon part of the Mirna river (Fiume Quieto), surrounded by lush vegetation.
 The surrounding, once much bigger, common oak forest - the only of that kind on the Croatian coast - is known as Motovunska Šuma (Foresta di Montona).
