Landscape Irrigation Design and Management
- 160k Downloads
Landscape irrigation design begins with an owner interview, site survey, and determination of the municipal water pressure and flow rate. This chapter includes a landscape drip and bubbler irrigation design program. The procedure begins with the measurement of the canopy diameter and crop coefficient for each plant in the landscape. This is followed by a calculation of the water requirement of each plant. Based on the water requirement, the program calculates the number of emitters required by each plant. Based on the reference ET, the program recommends and irrigation schedule. The procedure is similar to the calculation of an agricultural schedule except that density of planting, variable sizes of plants, and exposure to heat sources such as roads and buildings are also considered. The program also estimates the percent wasted water due to nonuniformity of application. This chapter also includes a design program for the pipe connection between the city water main and the valve box.
