BE CAREFUL WITH YOUR BIDS. HERE ARE THE INSTRUCTIONS. We have to calculate the irrigation needs and the risk of erosion by water, in a field of our option. We will use the Blaney-Criddle model and the USLE, respectively. We will use excel spreadsheets to carry out the calculations, by building the two models with the required equations and formulas. In this way, we will keep the two models for ever, ready-to-use in future problems. Below are some indicative steps to begin the assignment (general steps and the irrigation part -erosion part will follow): 1. Select a field in Google Earth. 2. Digitize the outline of it. 3. Enter some information: area, crop-cultivar, irrigation type, etc. 4. Save our project. 5. Assess the irrigation needs (for the hottest month in the area) with the Blaney-Criddle model: Find rainfall data [SOURCE: online weather data networks] Indicate C factor through slope measurement. Indicate t and p factors [SOURCE: online weather data networks for t; nomographs for p]. Built up the required formulas in excel; also, keep your notes, and provide justifications, and explanations in it. Convert mm of irrigation needs into water volume (in m3) for the whole field.
