STUDY OF HYDROLOGY

IMPORTANT RESEARCH. The International Union of Geodesy and Geophysics includes among its activities the .study of hydrology, and one of the constituent bodies of the Union is the International Association of Scientific Hydrology. At the last meeting of this Association, in Edinburgh, a list of important hydrological questions was agreed upon for discussion at the next meeting of the Association, which is to be helld at Washington in 1939. Briefly, the questions to be dealt with include a report on the present state of work on evaporation; the forecasting of floods; the conditions of 'transport of solid load in streams having a bed of loose sediment; a study of the temperature ruling in lakes and of the formation' and

dissipation of ice on lakes; the circulation of water and' water vapour; also the condensation of the tatter, between the surface of the ground and the zone of saturation; the definition of the various kinds of subterranean: waters; the permeability of snow and its retentive capacity; and the variations in the size of glaciers. The preparation of the British contributions to this discussion is being undertaken by the British National Committee of 'Geodesy and Geophysics, and the sub-committee on hydrology of this committee has arranged for the preparation of reports by some of its members. The Lieut.-Colonel E. Gold, D. 5.0., F.R.S., Meteorological Office, Air Ministry, Adastral House, Kingsway, London, who would like to bring to the notice of the sub-connnittee any relevant British investigation including investigations relating to colonies not likely to be directly represented in the International Union, are invited to communicate with him.
