USDA report on water and related land resources, Powder Drainage Basin, Oregon : based on a cooperative survey by the State Water Resources Board of Oregon and the United States Department of Agriculture : report

This report presents information concerning the water and related land resources of the Powder Drainage Basin. Its purpose is (1) to provide information on the past and present uses of water and related land resources; (2) to supply the production data from the use of these resources; (3) to assess the magnitude of water-related problems such as erosion, flooding, and drainage; (4) to indicate the probable direction of future use of water and land for agriculture and forestry in comparison to competing uses; and (5) to outline a general program for water and land resource management as a background for future detailed study and planning

An evaluation of urban flood estimation methodologies in Ireland

This paper summarises the findings of a study to evaluate the use in Ireland of the different flood estimation methodologies that can be applied to urban or urbanising catchments. The study, undertaken as part of the Office of Public Works‟ (OPW) Flood Studies Update programme, comprised both quantitative (posted questionnaires) and qualitative research (focus groups) targeting a range of organisations involved with planning and design issues pertaining to urban flooding. A total of 291 questionnaires was circulated. Of these, 100 were returned, equating to a response rate of 34%. Results indicate that formulae and methods for determining runoff rates in urban and urbanising catchments are being applied very generally without due consideration being given to the statistical foundation underlying the methods. The resulting inconsistencies in estimated runoff rates highlight the need for National Guidance for flow estimation in urban and urbanising catchments in Ireland.Other funderOffice of Public Work
