An official of the Department of Public Works and Highways (DPWH) yesterday assured the public that the Camanava flood control project. Effectiveness of CAMANAVA Flood Control Project: A Case Study of Selected Flood Control Structures during Typhoon Gener and Monsoon Rains in August. The CAMANAVA flood control project may be completed before the year is over.

Figure 1 shows the flood conditions year return without the infrastructure intervention, while Figure 2 shows the effect of the large flood control dam, which has ostensibly reduced the flooding. To evaluate the effectiveness, the research team consulted the initial project design and hydrological and geotechnical studies to ascertain expected flood mitigation results, and evaluated them against site visit observations conducted in early August before and after torrential rainfall.
Third, some construction remains incomplete and as built do not meet design specifications. You have successfully updated your account. Work at the University of the Philippines National Institute of Geological Sciences and Project Noah, using detailed Lidar data, can predict localized flooding due to short-duration intense rainfall.
If these concerns are not addressed in a transparent and scientific manner, one must question the motives for pushing through a project that is lacking in scientific preparation.
In contrast, Project Noah is barely 3 years old and has already made enormous impact on disaster prediction, with its results verified with actual data. For feedback, complaints, or inquiries, contact us. This solution should be cheaper and could camamava integrated in the overall scheme of flood water management, resulting in a much lesser discharge of floodwater into the metropolis, which would reduce the kind and amount of intervention.
Fireworks illuminate the skies despite the rain January 01, The immediate consequence of this is that engineering intervention e. Welcome to Rappler, please select your default country: But it contril extended by another 28 months until Use this link to cite this item: The proposed large dam flood control program is not designed properly because the flood model it is using is obviously substandard.
Eighteen natural and artificial waterways segment Malabon and crest during high tide and heavy precipitation. The new models should recognize increased severity and frequency of hydrometeorological activity resulting from climate change, such as greater maximum high tides, rising sea levels, and increased magnitude and frequency of precipitation. Our water specialist, Mr. There are enough competent Filipino engineers and projeft who are honest and patriotic.
The flood control project cmaanava has 26 components: Inhowever, the polder dike had to be raised by another meter Its height is We reserve the right to exclude comments which are inconsistent with our editorial standards.
Yearend thoughts on the AFP. This after the Pbillion project was approved by Neda. What is wrong with Figures 1 and camanavva Copyright C Hiroshima University Library. These capture tunnels might be more feasible than a proposed solution of making a channel from the Marikina Valley directly to the Manila Bay, f,ood running over infrastructure and residents.
See Figures 1 and 2.
P350-B flood control project flawed
The P3-billion contract for the flood control project was awarded to Nishimatsu in It will probably not work as designed and will probably be a vehicle for huge corruption. The second recommendation is to rebuild CAMANAVA flood control structures capable of sustaining longer term extreme hydrometeorological conditions based on the outputs derived from the modelling.
President Aquino was justified in canceling the Pbillion Laguna de Bay dredging contract which, not only was technically flawed, but also would not have served to control flooding in the metropolis. HiR is Open Archives Compliant.
This looks like the Pbillion project will be taken out as a loan, to be contgol by the Filipino people. Metro Manila Flood Control Plan. Street flooding in the metropolis after short but intense rainfall can cause havoc in terms of flooding, traffic and disrupted lives. Before year ends, Nietes captures 4th world title Boxing. The project has yet to be fully completed until now, however. Journal camanva International Development and Cooperation.
Second, camanzva designs failed to consider other factors such as land subsidence in its conceptual planning. I’ve read the Rappler privacy statementsite use policycomment moderation policy. In the Marikina-Montalban watershed, the possibility of capture tunnels to reduce the discharge of floodwater flowing into Cntrol and returning the captured water volume to the Sierra Madre divide for discharge eventually to the Pacific Ocean should be studied carefully.
Many details are missing, suggesting that the planning was not thorough. To improve flood control management in Malabon, this research team recommends a complete recalculation of hydrometeorological forecasts and structure design based on recently procured data, maps, and modelling techniques.
Sharapova campaign off to tough start in Shenzhen Other Sports. They should help vet these projects and help stop this great corrupt leakage of funds that conntrol have been used otherwise to build more classrooms, and other really needed and worthy infrastructure.
Any flood control program looking only at Laguna de Bay will be myopic and will be very difficult to implement. The testimony was considered crucial by both the Philippine and American lawyers for the Philippine position.
PB flood control project flawed | Inquirer Opinion
If the flood model basis is wrong, then how was the Pbillion estimate done? Flood control plans that will involve large dams in the Montalban watershed should also consider the existence of active faults in the area and the very large watershed congrol that will be flooded to accommodate the dam water.
Lidar data for Metro Manila, which are the most accurate, have been available only the past two years and already used by Noah for flood projections. Please try again later. We should end this rapacious cycle of creating substandard projects to be funded by sovereign loans from foreign banks that bring their own consultants who will not be looking out for genuine Philippine interests.
What is immediately obvious is that the flooding scenario is not as simple as the previous figures show. Any flood control plan is only as good as the quality of contrl topographic data used in the modeling and planning.
