Hydromet networks: guidance for sustainability

Image
Having worked for 10 years within Hydromet Networks and Early Warning Systems, I recommend this World Bank recent guide ,  as key reference for modernization and maintenance prioritizing sustainability, based in experience from developing countries but practically valid elsewhere.  “Grimes, David R.; Rogers, David P.; Schumann, Andreas; Day, Brian F.. 2022.

Sentinel-3 altimetry

Image
A new set of Land-Hydrology altimeter data from Sentinel-3 is available in pilot phase SR_2_LAN_HY , with a 27 days revisit time, and the orbit footprint as displayed in Copernicus OAH ,  in order to track water surface elevation at reservoirs, the case of Paso de las Piedras in Buenos Aires province, with orbits pictured.    

Breaching patterns:

Following Pakistan August 2022 floods, due to extreme monsoon rains, a HQ image of a plume in lake Manchar  attracted comments around the world: see space.com , or newsweek.com . We added those free imagery sets to train the algorithm to track flow patterns result of levee breaching , as this  phenomenon is essential to identify and manage floods  in near real time. The display shows a shift to reds from Sentinel-2 MSI, using Google-Earth-Engine. Other former testing case was at Honduras, after devastating hurricanes Eta and Iota, November 2021, where we trained with SAR Sentinel-1 imagery.      

Visionary notes:

While refining Risk and Damage evaluation tools for big-data, on high demand by Natural Catastrophe (NatCat) services, this rentrĂ©e we pay tribute to a visionary and  paradigmatic independent scientist: James E. Lovelock , passed away this summer aged 103, his latest guidance  book "Novacene" provides a global perspective to deal with earth's heat threat.

This week Kuala Lumpur hosts the International Geoscience and Remote Sensing Symposium , where state of the art Earth-Observation (satellite imagery) data integration for Hydromet services and natural Hazards resilience, are discussed. Special attention to  Floods and Landslides for rapid-response systems, by online sessions: WE6.V20 : Remote Sensing for the Sustainable Development Goals: Methods and Applications. TH5.V18 : Advanced Flood Monitoring and Prediction for Disaster Risk Reduction and Resilient Infrastructure.

Summer quiz: Po and Ebro

Image
Several similarities: basin surface, drainage collector topology, deltas sinking into Mediterranean sea, beloved by Roma Antica civilization, essential axis for northern regions across Italy and Spain respectively, etc. The Po is suffering its worst drought in 70 years, but what about the Ebro, that´s the summer quiz, compare both basins ...
