Project JYP-1104 SALT INTRUSION in GATUN LAKE a Major Qualifying
Project JYP-1104 SALT INTRUSION IN GATUN LAKE A Major Qualifying Project submitted to the Faculty of WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Bachelor of Science By Assel Akhmetova Cristina Crespo Edwin Muñiz March 11, 2012 Jeanine D. Plummer, Major Advisor Associate Professor, Civil and Environmental Engineering 1. Gatun Lake 2. Salt Intrusion 3. Panama Canal Abstract The expansion of the Panama Canal is adding another lock lane to the canal, allowing passage of larger ships. Increases in the number of transits and the size of the locks may displace more salt from the oceans into the freshwater lake, Gatun Lake, which is a drinking water source for Panama City. This project evaluated future salinity levels in Gatun Lake. Water quality and hydrometeorological data were input into a predictive hydrodynamic software package to project salinity levels in the lake after the new lock system is completed. Modeling results showed that salinity levels are expected to remain in the freshwater range. In the event that the lake becomes brackish, the team designed a water treatment plant using electrodialysis reversal for salt removal and UV light disinfection. ii Executive Summary The Panama Canal runs from the Pacific Ocean in the southeast to the Atlantic Ocean in the northwest over a watershed area containing the freshwater lake, Gatun Lake. The canal facilitates the transit of 36 ships daily using three sets of locks, which displace large volumes of water into and out of Gatun Lake. The displacement of water has the potential to cause salt intrusion into the freshwater Gatun Lake. -

HOW to POWER NAVIGATION LOCKS with ELECTRICITY by George Berman Alemán1
PIANC-World Congress Panama City, Panama 2018 HOW TO POWER NAVIGATION LOCKS WITH ELECTRICITY by George Berman Alemán1 1. WHY WE NEED AN “AIR LIFT LOCK” DEVICE? The need to power navigation locks with electricity is simply being able to operate the locks when hydropower is not available. This technology is developed considering Panama’s need for more revenues from the Canal and population’s need for more potable water. Panama’s water resources, primarily from Lake Gatun, are abundant but several droughts made the population aware of its limits. The record for most annual transits was set in 1971, 14,500 transits or nearly 40 transits per day. This number of transits is essentially the limit to Canal operations set by the availability of hydropower. The Panama Canal Authority has increased its revenues by increasing the size, not the number, of ships that transit the Canal daily. The Neo Panamax Locks increased the average ship size and revenues but has not increase the total number of transits. In 2017, the total transits were 13,549 or 37 transits per day. The technology to power navigation locks with electricity will allow Panama to exploit its principal resource, it’s geographic location, to its full potential without the limit imposed by the availability of water. It will eliminate draft restrictions on shipping through the Canal during droughts, and it will guarantee the population potable water without compromising canal operations. This technology is developed in Panama because water conservation has become one of our country’s greater needs. 2. DESCRIPTION OF DEVICE The device that powers navigation locks with electricity is described first, for the clarity of further explanations. -

Some Historical Aspects on the Hydraulic Design of the Gatun Spillway in the Panama Canal
8th IAHR ISHS 2020 Santiago, Chile, May 12th to 15th 2020 DOI: 10.14264/uql.2020.609 Some historical aspects on the hydraulic design of the Gatun Spillway in the Panama Canal A.V. Bal1, F. Re2, M.R. Lapetina2 & N. Badano2 1Panama Canal Authority Balboa, Panama 2Stantec Buenos Aires, Argentina E-mail: [email protected] ABSTRACT The Gatun spillway in the Panama Canal is built on top of the sea-level canal project, which was excavated between 1881 and 1887 by the Universal Company of the Interoceanic Canal, of France. The project was changed in October 1887 to a lock canal project. The design of the Gatun Spillway was developed between 1909 and 1911 by the Isthmian Canal Commission (ICC), an organization which reported directly to the United States Secretary of War, and which had the support of some of the best engineering minds working at the best universities, engineering companies and government institutions of the United States and Europe. A 1:32 scale physical model was used to aid in the spillway design. The spillway was completed in 1913 and the Panama Canal began operating on August 15th, 1914. This paper presents some engineering and historical aspects of the hydraulic design of the Gatun Spillway. The spillway design hydrograph and the methodology used to estimate the number of spillway gates required is contrasted to the current engineering practice. A detailed hydraulic engineering study was performed for the spillway between 2011 and 2013, in order to evaluate its hydraulic performance and to determine its discharge rating curve, using the OpenFoam CFD model and a physical model at a scale of 1:40.
