Hydrologic characteristics of catchments / Lag time for natural catchments
Hydrological characteristics of catchments : The systematic description and classification of catchment characteristics has never been adequately treated in any hydrological text. This paper summarises available measures for the quantitative description of catchments and points to aspects of catchment mensuration where deficiencies occur. Measures and definitions of catchment characteristics which have appeared in hydrological literature are described in 5 groups, these being topographical characteristics, vegetation, soils, climatic characteristics, and human effects. The characteristics of a catchment such as the unit hydrograph which are contained in the streamflow record are noted, and areal and temporal variations in characteristics are briefly discussed. Abstract for second paper, Lag time in natural catchments : The development of a relationship for the variable lag of ungauged catchments. Pluviograph and runoff records for an experimental catchment were studied in detail. A procedure was developed for the computation of the lag to direct runoff and the weighted mean discharge for any number of floods. This procedure was written into the form of a computer programme and the records of five catchments were analysed with the use of a digital computers. The relationships effect of other factors was studied. Finally the form of the relationships and the parameters defining them were related to the characteristics of the catchment areas....

Soil loss in a high country catchment : an investigation using fractional acre runoff plots to predict soil loss from a mountain catchment Hayward, John A. (Lincoln College, University of Canterbury, 1969)For the last 100 years, the condition of the New Zealand south Island high country has been the subject of much controversy. Although there are very few records of the condition of this land the time of European occupation ...
