4.Preserve Nutrients
5.Preserve soil structure
Disadvantages of drip irrigation are:
1.Leads to water to logging out soil
2.Soil salinity
3.Drainage problems in villages
4.It can cause death of fish
5.Excessive AMOUNT of fertilisers leads to algal growth.
hope it helps you. plz follow me and mark as brainliest

Advantages:

1. Suited to complete range of topographies and field dimensions. 
2. High irrigation efficiency DUE to UNIFORM distribution of water.
3. Accurate and easy measurement of water applied. 
4. Land leveling is not essential. 
5. Soluble fertilizer, herbicides and FUNGICIDES can be applied in the irrigation water economically and with little extra equipment. 

Limitation:

1. It requires high initial investment. 
2. Power requirement is usually high since sprinklers operate with more than 0.5 kg/cm2 water pressure. 
3. Fine textured soils that have low INFILTRATION rate can not be irrigated efficiently in host windy area. 
4. Loss of water due to evaporation from the area during irrigation. 
5. The water must be clean and free of sand, debris and large amounts of dissolve salts. 

Rain GAUGE density is very crucial in order to quantify the RAINFALL amount over a region. The level of rainfall accuracy is highly dependent on density and DISTRIBUTION of rain gauge STATIONS over a region.

The evolute of a curve is the locus of all its CENTERS of curvature. That is to SAY that when the center of curvature of each point on a curve is DRAWN, the resultant shape will be the evoluteof that curve. The evolute of a circle is therefore a SINGLE point at its center.

Rock Properties Affecting Groundwater:

The portion of a rock or soil not occupied by solid mineral matter may be occupied by groundwater. These spaces are known as voids, interstices, pores or pore space. Perhaps the most effective aquifers are sand and GRAVEL deposits, SANDSTONE and carbonate rocks. The permeability of limestone is usually due to solution that has enlarged the fracture and bedding planes into PASSAGEWAYS. The fractured zones of some of the denser rocks such as GRANITE, basalt and gabbro ALSO act as aquifers, although the permeability of such zones decreases rapidly with depth. Clay, shale and most crystalline rocks are typically poor aquifers.

Floods impact on both individuals and communities, and have social, economic, and environmental consequences. The consequences of floods, both negative and positive, vary greatly depending on the location and extent of flooding, and the VULNERABILITY and value of the natural and constructed environments they affect.

The consequences of floods, both negative and positive, vary greatly depending on their location, duration, depth and speed, as well as the vulnerability and value of the affected natural and constructed environments. Floods impact both individuals and communities, and have social, economic, and environmental consequences (Table 1).

Floods have large social consequences for communities and individuals
As most people are well aware, the immediate impacts of flooding include loss of human life, damage to property, destruction of crops, loss of livestock, and deterioration of health conditions owing to waterborne diseases. As communication links and infrastructure such as power plants, roads and bridges are damaged and disrupted, some economic activities may come to a standstill, people are forced to leave their homes and normal life is disrupted.

Similarly, disruption to industry can lead to loss of LIVELIHOODS. Damage to infrastructure also causes long-term impacts, such as disruptions to supplies of clean water, wastewater treatment, electricity, transport, communication, education and health care. Loss of livelihoods, reduction in purchasing power and loss of land value in the floodplains can leave communities economically vulnerable.

Floods can also traumatise victims and their families for long periods of time. The loss of loved ones has deep impacts, especially on children. Displacement from one's home, loss of property and disruption to business and social affairs can cause continuing stress. For some people the psychological impacts can be long lasting.

In Australia floods are the most expensive natural disasters
In Australia, floods are the most expensive type of natural disaster with direct costs estimated over the period 1967-2005 averaging at $377 million per year (calculated in 2008 Australian dollars).

Until recently, the most costly year for floods in Australia was 1974, when floods affecting New South Wales, Victoria and Queensland resulted in a total cost of $2.9 billion. The Queensland Government estimates costs for the 2011 floods will EXCEED this FIGURE for Queensland alone; with the damage to local government infrastructure estimated at $2 billion, and the total damage to public infrastructure across the state at between $5 and $6 billion.

Practical APPLICATIONS of Hydrology - The Study of Water. Hydrology is the study of the properties, quality, DISTRIBUTION, and MOVEMENT of water at and NEAR the earth's surface.

Given,
TIME period of the clock pendulum = 2.04 s

The NUMBER of oscillations made by the pendulum in ONE day is calculated as
Nmber of seconds in one daytime period of pendulum in seconds=24×36002= 43200

In each oscillation, the clock GETS slower by (2.04 − 2.00) s, i.e., 0.04 s.
In one day, it is slowed by = 43200 × (0.04)
                                          = 28.8 min
Thus, the clock runs 28.8 MINUTES slow during 24 hours.

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and winding currents to generate force in the FORM of rotation. Electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles or rectifiers, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators. An electric generator is mechanically identical to an electric motor, but operates in the reverse direction, accepting mechanical energy (such as from FLOWING water) and converting this mechanical energy into electrical energy.

Electric motors may be classified by considerations such as power source type, internal construction, application and type of motion output. In addition to AC versus DC types, motors may be brushed or brushless, may be of VARIOUS phase (see single-phase,two-phase, or three-phase), and may be either air-cooled or liquid-cooled. General-purpose motors with standard dimensions and characteristics provide convenient mechanical power for industrial use. The largest electric motors are used for SHIP propulsion, pipeline compression andpumped-storage applications with ratings reaching 100 megawatts. Electric motors are found in industrial fans, blowers and pumps, machine tools, household appliances, power tools and disk drives. Small motors may be found in electric watches.

In certain applications, such as in regenerative braking with traction motors, electric motors can be used in reverse as generators to recover energy that might otherwise be lost as heat and friction.

Electric motors PRODUCE linear or rotary force (torque) and can be distinguished from devices such as magnetic solenoids and loudspeakers that convert electricity into motion but do not generate usable mechanical force, which are respectively referred to as actuators and transducers.

Webster's method of traffic signal design is an ANALYTICAL approach of determining the optimum signal cycle time, CORRESPONDING to minimum TOTAL delay to all the vehicles at the approach roads of the intersection.

Defects must be defined, UNDERSTOOD, and RECORDED in order to create an appropriate maintenance plan. Maintenance PLANNING is solving an optimisation problem and it can be predictive. ... There are four main objectives of highway maintenance: REPAIR of functional PAVEMENT defects.

The Marshall METHOD, like other mix design methods, uses SEVERAL trial aggregate-asphalt binder blends (TYPICALLY 5 blends with 3 samples each for a total of 15 specimens), each with a different asphalt binder content. ... Therefore, the first STEP in sample preparation is to ESTIMATE an optimum asphalt content.

Answer:60

Explanation:

For calculating GROUND state of an element we USE the formula 2n^2

THEREFORE..

For n = 1 , 2n^2=2.

Same for n= 2 , 8.

n = 3 , 18.

n = 4 , 32.

Therefore 2+8+18+32=60.

As n>4.

Overview. Classical THERMODYNAMICSDEALS with STATES of dynamicequilibrium. The state of a SYSTEM atthermodynamic EQUILIBRIUM is the one for which some thermodynamicpotential is minimized, or for which the ENTROPY (S) is maximized, for specified conditions.

The geometric design of roads is the branch of highway engineering concerned with the POSITIONING of the physical elements of the roadway according to standards and constraints. The basic objectives in geometric design are to optimize efficiency and safety while minimizing cost and environmental damage. Geometric design also affects an emerging fifth objective called "livability," which is defined as designing roads to foster broader community goals, including providing access to employment, schools, BUSINESSES and residences, ACCOMMODATE a range of travel modes such as walking, bicycling, transit, and automobiles, and minimizing fuel use, emissions and environmental damage.[1]

Geometric roadway design can be broken into three main parts: alignment, profile, and cross-section. Combined, they provide a three-dimensional layout for a roadway.

The alignment is the route of the road, defined as a series of horizontal tangents and curves.

The profile is the vertical aspect of the road, including crest and sag curves, and the STRAIGHT grade lines connecting them.

The cross section shows the position and NUMBER of vehicle and bicycle lanes and sidewalks, along with their cross slope or banking. Cross sections also show drainage features, pavement structure and other items outside the category of geometric design.

1.The PURPOSE of SURVEY is to provide information's do government or planners or business enterprises. 2. Many enquiries aim to explain phenomenon 3. Surveys may be designed to make comparison of DEMOGRAPHIC groups.

2.Interpretation is the act of explaining, reframing, or otherwise SHOWING your own understanding of something. A person who translates one language into another is CALLED an interpreter because they are explaining what a person is saying to someone who doesn't understand.

As the name implies, rigid pavements are rigid i.e, they do not flex much under loading like flexible pavements. They are constructed using cement concrete. In this case, the load carrying CAPACITY is mainly due to the rigidity ad high modulus of elasticity of the SLAB (slab action). H. M. Westergaard is considered the pioneer in PROVIDING the rational treatment of the rigid pavement ANALYSIS.
