Swash. Swash, or forewash in geography, is a turbulent layer of water that washes up on the beach after an incoming wave has broken. The swash action can move beach materials up and down the beach, which results in the cross-shore sediment exchange. [1]
Longshore drift is simply the sediment moved by the longshore current. This current and sediment movement occurs within the surf zone. The process is also known as littoral drift. [1] Beach sand is also moved on such oblique wind days, due to the swash and backwash of water on the beach. Breaking surf sends water up the coast (swash) at an ...
Since waves rarely break onto a shore at right angles, the upward movement of water onto the beach (swash) occurs at an oblique angle. However, the return of water (backwash) is at right angles to the beach, resulting in the net movement of beach material laterally. This movement is known as beach drift (Figure 3).
Swachh India Movement (Urban) aims to free urban India from open defecation and 100% scientific management of municipal solid waste in 4,000+ cities across the country. One of its targets is to construct 66 lakh Individual Household Latrines (IHHLs) by October 2, 2019. However, this target has been reduced to 59 lakh IHHLS by 2019.
The swash zone is alternately covered and exposed by wave run-up. The beach face is the sloping section below the berm that is exposed to the swash of the waves. The wrack line (not shown here) is the highest reach of the daily tide where organic and inorganic debris is deposited by wave action. May have sand dunes. [2]
After breaking in the surf zone, the waves (now reduced in height) continue to move in, and they run up onto the sloping front of the beach, forming an uprush of water called swash. The water then runs back again as backwash. The water in the surf zone is relatively shallow, depending on the height and period of the waves.
The Swadhyaya Movement or Swadhyaya Parivara started in mid 20th-century in the western states of India, particularly Maharashtra and Gujarat. [1] Founded by Pandurang Shastri Athavale (1920-2003), the movement emphasizes self-study (swadhyaya), selfless devotion and application of Indian scriptures such as the Upanishads and Bhagavad gita for spiritual, social and economic liberation.
