Inadequate road design or maintenance leads to which type of accident?
View Answer Explanation
Rough crossing angle and sharp angle crossing are the causes of which type of accident?
The lowest portion of the capacity-elevation curve of a proposed irrigation reservoir draining 20 km2 of catchment is represented by the following data: i. The rate of silting for the catchment = 300 m3 / km2 / year ii. Life of the reservoir = 50 years iii. Dead storage = 30 iv. The FSD of the canal at the head = 80 cm v. The crop water requirement = 250 ha.m vi. Dependable yield of the catchment = 0.29 m Calculate the gross capacity of the reservoir.
As the height of a proposed dam is increased, the cost per unit of storage initially increases and then decreases.
The economical height of a dam is that height for which the ____________________
If 20% of the reservoir capacity is earmarked for dead storage in a storage reservoir of 30 M.cum and the average annual silt deposition in the reservoir is 0.1 M cum, then the useful life of the reservoir will start reducing after ____________
According to the Central Water Commission, the average annual evaporation loss is estimated to be _____________
Windbreakers, Integrated operation of reservoirs and Use of underground storage are all methods of ______________________
Reverse curve is a combination of two simple curves.
