The channel dimensions are as follows :

Bottom width (B) = 5.5 cm

Top width = 4.075 m

Flow velocity (V) = 1.76 m/s

Side wall length = = 2.03 m

The peak discharge in channel using rational method,

Q = C i A / 360

where, C = runoff coefficient of Kentucky grass = 0.22

i = Rainfall intensity = 2 cm /hr or 20 mm/hr

A= Catchment Area in hectares = 100 ha

=> Q = 0.22 x 20 x 100 /360

=> Q = 1.22 m3/s

Now, We know, for a best hydraulic trapezoidal section, top width should be twice of side walls .

Top width of trapezoidal channel = B + 2 m D

Side wall of trapezoidal channel = 2 D (1 +m2)1/2

=> B + 2 m D = 2 D (1 +m2)1/2

where, B = Bottom width

D= Depth of water

m = side slope m :1

Given side slope = 6 : 1

=> m = 6

=> B + 2(6)D = 2 D (1 +62)1/2

=> B + 12 D = 12.165 D

=> B = 0.165 D........................(1)

Now, according to Manning equation,

Q = (A/ N) R2/3 S1/2

where, Q = discharge = 1.22 m3/s

A = Cross-sectional Area of trapezoidal channel = BD + mD2 = 0.165 D2 + 6 D2 = 6.165 D2

N = Manning Roughness coefficient = 0.03

R = Hydraulic depth

S = Bottom slope = 3% or 0.03

Also,Now, second condition for a most efficient hydraulic trapezoidal channel is that the hydraulic depth (R) should be half of flow depth (D)

=> R = 0.5 D

Putting values in Manning Formula ,

1.22 = ( 6.165 D2 / 0.03) (0.5 D)2/3 (0.03)1/2

=> 30 = 205.5 D2 x 0.52/3 x D2/3 x 0.173

=> 1.22 = 22.41 D8/3

=> D = 0.335 m or 33.5 cm

From equation 1, B = 0.165 x 0.335 = 0.055 m or 5.5 cm

Also, velocity (V) = Q /A = 1.22 / (6.165 x 0.3352) = 1.76 m/s

Hence, channel dimensions are as follows :

Bottom width (B) = 5.5 cm

Top width = 5.5 + 2(6)(33.5) = 407.5 cm or 4.075 m

Flow velocity (V) = 1.76 m/s

Side wall length = D (1 + m2)1/2 = 0.335 (1 + 62)1/2 = 2.03 m

Answer: Therefore, the annual depreciation for each year using the double-declining-balance method is $228,000 for the first three years, $194,000 for the fourth year, and $0 for the fifth year. The book value at the end of each year is as follows: $422,000 at the end of year 1, $194,000 at the end of year 2, $228,000 at the end of year 3, $0 at the end of year 4, and $80,000 at the end of year 5.

Explanation:  To calculate the annual depreciation using the double-declining-balance method, we first need to calculate the depreciation rate, which is double the straight-line depreciation rate. The straight-line depreciation rate is calculated as follows:

Depreciation rate = (Cost - Salvage value) / Useful life

Depreciation rate = ($650,000 - $80,000) / 5 years = $114,000 per year

Double-declining-balance depreciation rate = 2 x straight-line depreciation rate = 2 x $114,000 = $228,000 per year

Using this depreciation rate, we can calculate the annual depreciation and book value at the end of each year as follows:

Year 1:

Depreciation = $228,000

Book value = Cost - Depreciation = $650,000 - $228,000 = $422,000

Year 2:

Depreciation = $228,000

Book value = Cost - Depreciation = $650,000 - $228,000 - $228,000 = $194,000

Year 3:

Depreciation = $194,000

Book value = Cost - Depreciation = $650,000 - $228,000 - $194,000 = $228,000

Year 4:

Depreciation = $228,000

Book value = Cost - Depreciation = $650,000 - $228,000 - $194,000 - $228,000 = $0

Year 5:

Depreciation = $0

Book value = Salvage value = $80,000

The two types of primary memory are RAM (Random Access Memory) and ROM (Read Only Memory).

RAM  (Random Access Memory)  is volatile memory, meaning that it is temporary and is cleared when the computer is shut down. It is used for short-term storage of data and program instructions that the computer is currently using. RAM is divided into two categories: dynamic RAM (DRAM) and static RAM (SRAM). DRAM is the most common type of RAM and is used in most computers. It needs to be constantly refreshed to retain the data it holds. SRAM, on the other hand, is faster and more expensive than DRAM, but does not need to be refreshed.

ROM,  (Read Only Memory). on the other hand, is non-volatile memory, meaning that it retains its contents even when the computer is turned off. It stores the BIOS (Basic Input/Output System) firmware that is used to boot up the computer, as well as other firmware that is used by devices such as printers and scanners. ROM cannot be modified, which is why it is called "Read Only Memory." However, there are some types of ROM that can be modified, such as EEPROM (Electrically Erasable Programmable Read-Only Memory) and flash memory.

In summary, RAM is volatile memory that is used for short-term storage of data and program instructions, while ROM is non-volatile memory that stores firmware used for booting up the computer and other devices.

Security groups and role-based permissions management are both methods for controlling access to resources in a system, but they differ in their approach.

Security groups are a collection of users or entities that have the same level of access to a resource. They are typically created based on job function or department, and can be used to grant or revoke access to resources as needed. For example, a security group might be created for all employees in the finance department, and they would have access to specific financial systems and data.

Role-based permissions management, on the other hand, is a more granular approach to access control that assigns specific permissions to individual users based on their role or job function. This means that each user can have a unique set of permissions based on their specific needs. For example, a manager might have access to view and approve reports, while a regular employee might only have access to view their own reports.

In summary, security groups provide a broad level of access control based on job function or department, while role-based permissions management provides a more specific and individualized approach to access control based on user roles or job functions.
