This document describes Green SAB Technology, which uses specially designed artificial units called SAB (Sediment Accumulator in Beach) units to protect soils from erosion in hydraulic environments like beaches, river banks, and around structures. The SAB units dissipate flow energy and allow sediments to accumulate around them, providing a buffer against scouring. The first project implementing this technology was in 2008 at Radisson Blu Temple Bay Beach Resort in India, which recovered the eroded beach. A second project in Gujarat, India was completed in 2015 and also accumulated sediments to develop an artificial beach using SAB units. The technology aims to provide scour protection with minimal disturbance to local environments and allows engineered green space development with trapped

(Pioneers of Soil Scour Protection in any Hydraulic Environments)
Green SAB Technology for Artificial Hydraulic Bed Development
(Indian Patent No : 268563 granted on 3rd September 2015)
Genre
This technology, in general, is a solution to Soil Scour and Sedimentation at the boundary of water and soil
in any Hydraulic Environments. This technology is commonly applicable at the boundaries of water and soil
in case of beaches, river banks, river beds, offshore seabed, scour protection of toe of river embankments,
breakwaters, seawalls, around any land and marine hydraulic structures, offshore wind energy towers and
bed scour protection for intake and exits of pump houses.
Concept
Erosion of soil in any hydraulic environment at the boundary of water and soil takes place primarily due to
hydraulic soil scour. This hydraulic scour takes place when pore pressure in the soil reaches beyond the
sustainable levels of soil stability by its weight due to adjacent water that is in dynamic random motion.
The dynamic motion of adjacent water causes the variations of pore pressures in the soil as part of natural
or artificial hydraulic processes. So, scour reduction is the basic principle of this technology. Scour
reduction in this technology is achieved by inducing flow energy dissipation using specially designed
artificial deadweight SAB units. Consequent to the use of this technology and its resultant relatively calm
flows, the accumulation and gravitational settlement of sediments around these artificial SAB units result
protection of anthropogenic developments including habitation adjacent to the erodible or scourable
boundaries of water and soil in any hydraulic environment. Existing methods of protection for soil erosion
on the beaches, river banks, etc. are like the game between the nature and humans with sword by the
nature and shield by the humans.
What is SAB?
(S)ediment (A)accumulator in (B)each of a coast, at (B)anks of enclosed water bodies like river, Lakes,
(B)eds of any hydraulic environments and (B)oundaries around any land, marine and offshore hydraulic
structure. “B” in the acronym represents the boundary between soil and water in all possible natural and
anthropogenic processes. So, it is called SAB Technology. These artificial sediment accumulator units are
called SAB Units.
How it is Green and Green SAB Technology?
Hydro-dynamically Green Resilience
In dynamic traffic systems, green signal is an indicator of “Go Ahead” to indicate that there is no
disturbance to moving vehicle. The artificial unit of this technology is like a Green Signal of dynamic
hydraulic environments. It does not disturb significantly the adjacent hydraulic environments of artificial
units. So, it is a Green Concept, while finding a solution to problem, based on the principles of all
dynamic systems are addressed without any significant disturbance or with no disturbance. In the present

case, the SAB unit disturbs the
local hydraulic environment such
that it induces siltation around it
and in turn it builds buffer
sediments against soil scour
initially and reinforced
sedimented bed to sustain against
soil scour on long-term period. It
is the synergy of SAB Units.
Soil-Eco Resilient Green
Space Development
The environment of accumulated
sediments/ soils can be
engineered to develop the Green
spaces to provide various kinds of
ecosystem service functions
around the location of soil scour
stabilized by the concept of SAB Technology.
So this concept is a twin-sharp-edged concept of hydraulic and soil environments with insignificant (Green)
disturbance to local natural and anthropogenic hydraulic processes and
development by humans in the artificially accumulated soils of this dynamicall
is known as Green SAB Technology.
