A numeric
counter for each data set within the database [ 869 sets ] |
| (2) |
The name of the
river upon which the measurement site is located |
| (3) |
The name of the
measurement site at which the tabulated data was collected |
| (4) |
Numeric code
for each individual river name within the database [ 569 rivers ]. Many
of these rivers are themselves tributaries of others. |
| (5) |
Number of
monitoring stations on each of the rivers in Column (4) |
| (6) |
Number of
different data sets obtained at the same monitoring site |
| (7) |
Name of the
river that has lowest order i.e. that flows into the sea or into inland
pans or depressions |
| (8) |
Names of the
rivers which are tributaries of those in (7) |
| (9) |
Names of the
rivers which are tributaries of those in (8) |
| (10) |
Names
of the rivers which are tributaries of those in (9)
Note : The river upon which monitoring has taken place
is provided in the highest order column of (7), (8), (9) or (10). If a
monitored river is unknown or is a tributary but of an unknown river,
'UNKNOWN' has been entered in the appropriate column (7), (8), or (9) |
| (11) |
Details the
rivers on which measurements are have been made, i.e. where it flows to,
whether it is dammed etc. |
| (12) |
The name of the
country in which the measurements have been made |
| (13) |
The name of the
continent in which the measurements have been made : Africa, Asia,
Europe, North America, South America or Pacific. The authors have made
judgements about the appropriate continent to place some rivers, such as
those in Papua New Guinea which have been included in Asia rather than
Pacific |
| (14) |
The Latitude of
the measurement site, where known |
| (15) |
The Longitude
of the measurement site, where known |
| (16) |
The catchment
area upstream of the measurement site |
| (17) |
The year in
which a given set of data at a site was begun |
| (18) |
The year in
which a given set of data at a site ended |
| (19) |
The mean annual
rainfall occurring in the area upstream of the measurement site for the
period given in (17) and (18) |
| (20) |
The mean annual
runoff occurring at the measurement site for the period given in (17)
and (18) |
| (21) |
The mean
sediment load recorded for the monitored time period when the influence
of dams or human and/or natural changes are NOT known |
| (22) |
The mean
sediment load recorded PRIOR TO the construction of an upstream dam.
Uncertainty exists over the exact dates monitored |
| (23) |
The mean
sediment load recorded AFTER the construction of an upstream dam.
Uncertainty exists over the exact dates monitored |
| (24) |
The mean annual
sediment yield at the measurement site for the period monitored. The
method of measurement can influence this. Limited details, where known,
are provided in columns (25) and (30) |
| (25) |
The word
'Reservoir' when the data measured has been derived from reservoir
survey data. The yield column (24) has been modified where possible by
use of Brunes curves to take account of trapping efficiency |
| (26) |
The volume of
the reservoir in the INITIAL year of monitoring used to derive yield |
| (27) |
The volume of
the reservoir in the FINAL year of monitoring used to derive yield |
| (28) |
Provides a code
for the reference source(s) from which the
authors obtain the data used in compiling this database |
| (29) |
Provides
details of the source referenced by the references used in column (28) |
| (30) |
Provides
details pertaining to data entry, method of measurement when known,
conversions used and other information relevant to information
consistency |
