Two crops with the following data ,for the first crop A1= 40 cm, B1= 160 day and the area - be irrigated= 6000 hectares. For the second crop A2= 100 cm, B2= 120 days, area to be rrigated= 4000 hectares. The required design discharge at * :outlet is

The gross commanded area for an irrigation canal is 15,000 hectares out of which 80 percent is cultural commanded area. The intensity of irrigation is 50 percent for rabi. If the kor period is 4 weeks for rabi, determine the (i) outlet discharge. The outlet factor for rabi may be assumed as 1800 hectares/cumec. (ii) also calculate the delta for rabi.

Problem- The command area of a canal grows only one crop. i.e., wheat. The base period of wheat is 120 days and its total water requirement, A. is 40 cm. If the canal discharge is 2 m³/s. the area, in hectares, rounded off to the nearest integer, which could be irrigated (neglecting all losses) is?

An outlet irrigates an area of 20 ha. The discharge (l/s) required at this outlet to meet the evapotranspiration requirement of 20 mm occurring uniformly in 20 days neglecting other field losses is?

Irrigation, civil.

There are currently 420 inhabitants in the small village of Pravino. The population is estimated to increase to 940 in thirty years. The current average peak flow is 1.2 L/s and is expected to increase to 2.14 L/s by 2050. The organic load is approximately 45 g BOD5/capita/day. The community is considering a free surface wetland or a lagoon to treat their wastewater.   1. Use the BOD loading to estimate the maximum surface area (in ha) required for a free surface wetland to serve the community by 2050 and remove BOD to 30 mg O2/L and TSS to 30 mg/L.

The culturable commanded area for a distributary is 2 x 10⁰ m². 82 m². The intensity of irrigation for a crop is 40%. If k or water depth and k or period for the crop are 14cm and 4 weeks, respectively, the peak demand discharge is

What is the design discharge.
