The Culturable Command Area (CCA) for a canal is 10000 hectares. The base period for a crop in the CCA is 140 days. Watering depth for the crop is 40 cm. The outlet discharge (in m...

Width (in m) of a rectangular channel required to carry a discharge of 96 m³/s at a critical depth of 9.8 m is __________ (rounded off to two decimal places). Use acceleration due...

Two soils of permeabilities k₁ and k2 are placed in a horizontal flow apparatus, as shown in the figure. For Soil 1, L1 = 50 cm, and k₁ = 0.055 cm/s; for Soil 2, L2 = 30 cm, and k2...

A 60 cm diameter well completely penetrates a confined aquifer of permeability $5 \times 10^{-4} \mathrm{~m} / \mathrm{s}$. The length of the strainer (spanning the entire thicknes...

A canal supplies water to an area growing wheat over 100 hectares. The duration between the first and last watering is 120 days, and the total depth of water required by the crop i...

The cross-section of a small river is sub-divided into seven segments of width 1.5 m each. The average depth, and velocity at different depths were measured during a field campaign...

Two reservoirs are connected by two parallel pipes of equal length and of diameters 20 cm and 10 cm, as shown in the figure (not drawn to scale). When the difference in the water l...

Depth of water flowing in a 3 m wide rectangular channel is 2 m. The channel carries a discharge of 12 m³/s. Take g = 9.8 m/s². The bed width (in m) at contraction, which just caus...

A 1:50 model of a spillway is to be tested in the laboratory. The discharge in the prototype spillway is 1000 m³/s. The corresponding discharge (in m³/s, up to two decimal places)...

The intensity of irrigation for the Kharif season is 50% for an irrigation project with culturable command area of 50,000 hectares. The duty for the Kharif season is 1000 hectare/c...

In a 5 m wide rectangular channel, the velocity u distribution in the vertical direction y is given by $u=1.25y^{\frac{1}{6}}$. The distance y is measured from the channel bed. If...

A sluice gate used to control the flow in a horizontal channel of unit width is shown in the figure. It is observed that the depth of flow is 1.0 m upstream of the gate, while the...

In a laboratory, a flow experiment is performed over a hydraulic structure. The measured values of discharge and velocity are 0.05 m³/s and 0.25 m/s, respectively. If the full scal...

The culturable command area of a canal is 10,000 ha. The area grows only two crops-rice in the Kharif season and wheat in the Rabi season. The design discharge of the canal is base...

An outlet irrigates an area of 20 ha. The discharge (lit/sec) required at this outlet to meet the evapotranspiration requirement of 20mm occurring uniformly in 20 days neglecting o...

The culturable command area for a distributary channel is 20,000 hectares. Wheat grown in the entire area and the intensity of irrigation is 50%. The kor period for wheat is 30 day...
