MODERN TECHNOLOGIES IN HYDRO-METEOROLOGICAL INFORMATION SYSTEMS MARK HEGGLI, INNOVATIVE HYDROLOGY CONSULTING METEOROLOGIST/HYDROLOGIST TO THE WORLD BANK
AREAS OF TECHNOLOGY ADVANCEMENT RECENT TECHNOLOGY ADVANCEMENTS ALLOW MORE INFORMATION TO BE AUTOMATICALLY AND RELIABLY COLLECTED, PROCESSED, AND IN SOME CASES DELIVERED TO CONSUMERS. IF APPLIED PROPERLY, THE PROPER USE OF MODERN TECHNOLOGY INCREASES THE POSITIVE VISIBILITY OF A HYDROMET SERVICE AREAS THAT WILL BE PRESENTED MEASUREMENT AND COLLECTION PROCESSING & ANALYSIS SERVICE DELIVERY
DATA COLLECTION AND TRANSMISSION NON-CONTACT SURFACE WATER MEASUREMENT HAVE BECOME COMMON OVER THEY PAST 15 YEARS ULTRASONIC WATER LEVEL RADAR WATER LEVEL DOPPLER VELOCITY DISCHARGE SIMILARLY ACOUSTIC DOPPLER CURRENT PROFILERS (ADCP) HAVE BEEN INCREASING IN USE IN FAVOR OVER MECHANICAL STREAM GAUGING TECHNOLOGY

GROWING PROBLEM: PROPER CHOICE OF TECHNOLOGY FOR GIVEN SITUATION MISAPPLICATION OF SIDE-LOOKING ADCP S RIVERS THAT ARE BETTER SUITED FOR STAGE-DISCHARGE CALCULATION RIVERS WITH UNSTABLE BANKS MISAPPLICATION OF DOPPLER VELOCITY DISCHARGE SENSORS RIVERS THAT ARE BETTER SUITED FOR STAGE-DISCHARGE CALCULATION MISAPPLICATION OF LEVEL MEASUREMENT PLACED OVER RIVER ANOMALIES POOR CHOICE OF DATA TRANSMISSION METHOD
THE ROLE WEATHER RADAR IN HYDROLOGY INSTANTANEOUS RAINFALL RATE VOLUMETRIC MEASUREMENT OF RAINFALL RATE QUANTITATIVE PRECIPITATION ESTIMATE QUANTITATIVE PRECIPITATION FORECAST ABILITY TO DEVELOP AN EXTENSIVE VIRTUAL RAIN GAGE NETWORK ADDS LEAD TIME FOR FLASH FLOOD SINGLE ASSET TO MAINTAIN RATHER THAN NUMEROUS
GUIDING CONSIDERATIONS FOR WEATHER RADAR NETWORK DESIGN FOR WEATHER RADAR TO BE EFFECTIVE IN ESTIMATING RAINFALL THE RADAR BEAM MUST BE AS CLOSE AS POSSIBLE TO THE GROUND AS POSSIBLE, WITH THE RESULTS BEING OVERSHOOTING RAIN PRODUCING CLOUDS DECREASED REPRESENTATIVENESS ASSOCIATED WITH THE IMPACTS OF WINDS. THE FURTHER THE RAIN DROP MUST FALL, THE FURTHER IT WILL BE DISPLACED FROM THE PARENT CLOUD
MISREPRESENTATION OF RAINFALL
OPTIMUM RADAR SITING CONCEPT: FLOOR ANALYSIS
PROCESSING AND ANALYSIS BRINGING IT TOGETHER
DATA PROCESSING HAS COME A LONG WAY
Millions of pieces of information Transformed into products to support decisions Data Integration Early Warning Hydroelectric Scheduling River Forecasting Water Supply Forecasting Ag Central Decisions Asia Water Future Forum and Exposition

SUMMARY THERE ARE MANY NEW ROBUST, SUSTAINABLE MONITORING TECHNOLOGIES SOLUTIONS ARE OFTEN MISAPPLIED, WHICH RESULTS IN A WASTED INVESTMENT. A WELL THOUGHT OUT DESIGN IS NECESSARY WRONG TECHNOLOGY (ADVANCED SYSTEMS FOR SIMPLE MONITORING) TECHNOLOGY IS NOT SUSTAINABLE (IRIDIUM VS METEOSAT) HIGH SOFTWARE LICENSE FEES WHEN SUITABLE OPTIONS ARE AVAILABLE WITH FREE LICENSE SOME SOLUTIONS ARE NOT WORTH THE INVESTMENT, EVALUATE HOW YOU WILL USE THE INFORMATION FOR EACH PIECE OF EQUIPMET THE ACQUISITION AND APPLICATION OF MODERN TECHNOLOGY WILL BE LARGELY WASTED WITHOUT LIKE IMPROVEMENTS IN TARGET SERVICES
