<br />search-. First year report to Office
<br />of Water Resources Research, U.S.

<br />.
<br />
<br />Key words: rainfall-runoff relation-
<br />ships; urbanisation; data collection;
<br />storm runoff: urban hydrology: urban
<br />drainage'.

<br />.
<br />
<br />The first year emphasis was on subjects
<br />reguiring earliest consideration, such
<br />as urban storm drainage. An assessment
<br />is given of the potentials, liabili-
<br />ties, and available knowledge of the
<br />rainfall-cunoft-water quality process,
<br />and model requirements for process sim-
<br />ulation are detailed. Immediate re-
<br />search needs with regard to damage eva-
<br />luation are given, and the utilisation
<br />of storage to ameliorate flooding is
<br />outlined. Th~ principal non-hydrologic
<br />aspects of urban water are listed, and
<br />include administration of works, eco-
<br />nomics of planning and operation, fi-
<br />nancing of systems, recreational facil-
<br />ities, planning and operation, and so-
<br />ciological problems. The report con-
<br />tains 11 appendices, each with techni-
<br />cal papers dealing with the appendix
<br />subject.

<br />This progress report includes brief
<br />discussions of the future impact of ur-
<br />banisation on hydrology in the United
<br />States, the factors directly contribut-
<br />ing to flooding in urban areas and the
<br />critical research work required in this
<br />field. The main part of the report is
<br />an annotated bibliography of urban hy-
<br />drology, and an appendix of current re-
<br />search projects in urban areas of the
<br />United States.

<br />Under the U.S.G.S. - sponsored portion
<br />of the program, an intensive study is
<br />being made: of the types of data need-
<br />ed for improved design of storm drain-
<br />age facilities, including both Quantity
<br />and quality of drainage flow: of needs
<br />for data collecting instrumentation:
<br />and of types of networks necessary to
<br />collect adequate data. The ultimate
<br />objective is to facilitate transfer of
<br />data findings between metropolitan re-
<br />gions.

<br />yields-. .1. Hydraul. Oivn., ProC'.
<br />ASCE, Vol.96(HY6); p1283-1329.
<br />
<br />Key words: channel erosion: erosion;
<br />erosion rates; sediment yield.
<br />
<br />Methods and procedures are ana lysed for
<br />det~rmining erosion rates, sediment
<br />yield, or deposition rates at locations
<br />downstream from the erosion source.
<br />Emphasis is given to th~ erosion types
<br />and processes which cause the most en-
<br />gineering problems, either by the large
<br />sediment quantities involved or by the
<br />locally severe damages. Accelerated
<br />erosion and deposition rates caused by
<br />man's activities are of special
<br />concern; these derive from she~t ero-
<br />sion processes on tilled lands and from
<br />such specialised activities as strip
<br />mining, urban development, consruction
<br />of highways and utilities, anq sheet
<br />erosion on any portion of the lan~ sur-
<br />face that is denuded or inadequately
<br />protected. Present bases for estim~t-
<br />ing these rates on both a storm and an
<br />average annual basis are given.

<br />Selected papers from the ASCE Irriga-

<br />conference, Fort Collins, Colorado;
<br />B00pp.
<br />
<br />Key words: urban drainage; weather
<br />modification; ground water resources.
<br />
<br />The conference objective was to explore
<br />many of the questions of the interne-
<br />pendencies betw~en urban and irrigation
<br />water use. The twelve broad subjects
<br />discussed were qround water, changing
<br />water use, weather modification, drain-
<br />age by pumping, operation and maintp.-
<br />nance, efficient irrigation., autt)matic
<br />controls, agricultural and urban consi-
<br />derations, suburban drainage, water
<br />utilisation, irrigation ~ater require-
<br />ments, and water quality.

<br />An International Workshop was held by
<br />IHD-UNESCO on the Hy1rological Effects
<br />of Urbanisation. The develooed coun-
<br />tries have already experienced the ef-
<br />fects of urbanis~tion on the hydroloqi-
<br />cal cycle, and u~banisation of areas is
<br />increasing with likelihood thst further
<br />damage will be none. There is also ev-
<br />idence that urbanisation will increase
<br />in the developing countries and that
<br />problems will arise tbere similar to
<br />those that have been encountered else-
<br />where. The ~ffects of water .pollution
