Project Description

  Valenciano is a proposed dam on the Valenciano River in Puerto Rico with funding from FEMA intended for water supply and flood control. The design for the dam consists of four radial gates bound on the sides by a turbidity tower and obermeyer gate. 

The purpose of the physical model is to help guide design choices related to the stilling basin depth and length, spillway crest geometry, radial gates, baffle block configuration, obermeyer gate, and turbidity tower while comparing the results of the model against computer models. In addition, the physical model will be used to guide operational procedures for radial and obermeyer gates and turbidity tower. 

Upon completion of testing, an optimal design will be reached that performs sufficiently up to the probable maximum flood, while minimizing the length and depth of the stilling basin and extent of energy dissipation structures.

Testing will encompass measurements of water surface elevations and velocities in the reservoir, stilling basin, and exit channel to support quantitative analysis, along with video footage of different testing configurations for visual comparison.

Key Highlights

  • Construction consists of a bolted aluminum frame decked with plywood and overlayed by high-density milled foam spray coated with polyurethane spray. Acrylic panels form the turbidity tower and model walls.
  • Radial gates are manipulated by four electric actuators.
  • Data collection is completed using ultrasonic sensors, acoustic doppler velocimeters, and point gages.
  • The model is 1:24 scale.
