Research Project: Development of a Three-dimensional Hydrodynamic Model of the Irrigation Canals at Tipon, Peru

Location: Watershed Physical Processes Research

Project Number: 6060-13000-026-19-N
Project Type: Non-Funded Cooperative Agreement

Start Date: Mar 1, 2016
End Date: Feb 28, 2018

Objective:
The overall objective is to develop improved understanding of irrigation canal design in very steep, confined Peruvian mountain environments. Specific subobjectives are: 1) Develop relations between discharge and planimetric and altimetric profiles and cross-sectional shape of the existing irrigation canals at Tipon, Peru; 2) Evaluate energy dissipation locations; 3) Enhance the USDA-ARS capabilities to reconstruct ground surface from a combination of surveying technologies; and 4) Conduct a hydrodynamic analysis of the irrigation canal network at Tipon, Peru.

Approach:
Improved understanding of irrigation canal design in very steep mountain environments will be developed from the existing irrigation canal complex at Tipon, Peru. High-resolution topographic data will be collected and analyzed using USDA-ARS surveying and surface reconstruction technology to obtain highly accurate cross-sectional, longitudinal, and planimetric information of the irrigation canal complex. These data and the TELEMAC software from Electricity of France, which was recently enhanced by ARS, will be used to develop a three-dimensional computer model to study the hydrodynamics of the complex. The model outcome will then be analyzed to determine: a) relationships between irrigation canal geometry and discharge, and b) energy dissipation locations.
