摘要:

Based on the I.H.D. Resolution 1–12 the Commission of Snow and Ice of the I.A.S.H. prepared guide lines for the recording and mapping of the worldwide distribution, water equivalent and related data of 1) the total seasonal snow cover, 2) the sea, lake and river ice, and 3) the perennial ice and snow masses on and beneath the land surfaces. Using the glacier inventory as an example, the problems of standardization and presentation of data are discussed. The operation of a computer program written for a Univac 1108 and the use of its ‘control’ cards for the analysis of glacier inventory data from a test area in the Canadian Arctic (Axel Heiberg Island) is outlined. The program presently sorts according to characteristics and classification numbers. A range of variables may be chosen and any one variable is averaged, totalled or histogrammed as instructed by the control cards. A brief description of the program is included. The development of a second stage to the program is envisaged.

摘要:

Optimum utilisation of natural hydrologic system models, in water supply engineering problems, leads to successive approximation tactics and to alternate recourse in models and in natural hydrologic systems (examples quoted from the south-east of France).

摘要:

The effective porosity θefor partially penetrated aquifers was determined. The model basin sandy aquifer available in the Centre was used. The values obtained for θewere in good agreement with the adopted values.

摘要:

Near Buckeye, Arizona, saltcedar (Tamarix pentandra) was grown on a battery of evapotranspirometers under various conditions of plant density, soil salinity, and access to water. Growth and development of these plants declined sharply at the beginning of each July, although before that time rates of growth and development had been very high. It was initially postulated that carbon dioxide might have become the limiting factor. Measurements of CO2content of the air made at different heights inside and outside the evapotranspirometers, however, showed that this was not the case.

摘要:

In areas of accentuated relief, some of the basic assumptions made in the use of standard methods of assessing areal mean rainfall are often untenable. It is shown in this paper, that, not only does topography affect the actual rainfall distribution, but that the areal variability, measured as the correlation between any two points, is also dependent on the relief. Two methods are used to show this. Once method compares the areal variability of a flat area to one of accentuated relief, while the second method relates areal variability to topographic factors using a multiple regression technique.
