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

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.

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.
