Philosophy and principles for estimating and analyzing radar rainfall data
Prepared by the Surface Water Hydrology Technical Committee of the Environmental and Water Resources Institute (EWRI) of the American Society of Civil Engineers (ASCE) and edited by Chandra S. Pathak, Ph.D., P.E., D.WRE and Ramesh S. V. Teegavarapu, P.E., Radar Rainfall Data Estimation and Use provides a detailed look at the basic philosophy and principles for estimating and analyzing radar rainfall data.
Rain gauges not cost effective in providing information about the spatial distribution of rainfall
As one of the many significant recent advances in hydrologic engineering and practice, radar-derived rainfall estimation serves as a valuable resource for engineering and construction (E&C) companies, and for weather enabled decision support solutions. The resource highlights how “…rain gauges provide point values of rainfall depth and intensity but are not cost effective in providing information about the spatial distribution of rainfall.”
A framework to develop radar rainfall data sets and analyze the data
On balance, radar-derived rainfall data provides a density of measurements which cannot be obtained only by rain gauge. However, Radar Rainfall Data Estimation and Use explains how integrating rainfall data sets both from rain gauges and from radar produces better rainfall estimates. In summary, the radar rainfall data resource provides a framework to develop radar rainfall data sets and analyze the data according to numerous goals and objectives.
In-depth technical information and detailed analysis on rainfall data estimation and use
Radar Rainfall Data Estimation and Use is ASCE Manuals of Practice (MOP) 139. “ASCE Manuals and Reports on Engineering Practice (Manuals of Practice, or MOPs) present in-depth technical information on a specific topic and provide detailed analysis of the limitations and applications of the described methods and technologies. The practical information contained in MOPs is useful to the typical civil engineer in everyday work.”
Further, MOP 139 and other Manuals of Practice must be prepared by committees under the direction of an ASCE division, council, or institute, such as the Surface Water Hydrology Technical Committee of the Environmental and Water Resources Institute (EWRI); undergo review and approval by a Blue Ribbon Panel of experts; and be approved by the appropriate executive committee.
