DamData.txt
This file contains dam properties for outlet lakes that operate as reservoirs (i.e. dams) and which do not use general parameters (so the term olake below refers to those olakes that are reservoirs/dams). Properties defined here override the properties and generic parameters given in GeoData.txt and par.txt. Dams defined in DamData.txt can not be included in LakeData.txt (with the exception of a LakeData.txt with only nutrient model parameters). Dam properties include physical characteristics, e.g. depth, and regulation routine parameters. In DamData.txt, four different dam types with different purposes may be used. These are irrigation dam, water supply dam, flood control dam and hydropower dam. Each typ has its own rules for regulation. Hydropower dams are regulated similar to the routines in LakeData.txt, but not totally.
DamData.txt can only be used for standard olake (ldtype=1 as defined for LakeData.txt), no lakebasins are allowed.
DamData.txt is a tab-separated file located in the modeldir folder. Lakes and lake basins are listed row-wise. The first row contains a column header with variable names. Variable names are not case-sensitive (max. 10 characters, no spaces). Columns with headings unknown to HYPE are skipped while reading the file, but must not longer than ten characters. Columns containing character strings, e.g. descriptive meta-data, must not exceed a length of 50 characters. The columns may be in any order. A value must exist for every column and row, i.e. empty cells are not allowed. Maximum 50 columns allowed.

The table below describes all LakeData.txt columns read by HYPE.
| Variable ID | Unit | Type | LdType | Description |
|---|---|---|---|---|
lakedataid | - | general | 1/3/4 | lake/lake basin ID (integer), used to connect lakes/lake basins to subbasins in GeoData.txt (mandatory) |
lakeid | - | general | 2/3/4 | lake ID (integer), used to connect lake basins to multi-basin lakes. Unique integer, 0 for simple outlet lakes (ldtype = 1) |
ldtype | - | general | all | code for lake data type (LdType), integer betwen 1 and 4 (mandatory): 1 - simple outlet lake 2 - multi-basin lake, i.e. covering several HYPE sub-basins, generic lake/outflow properties 3 - upstream lake basin of a multi-basin lake 4 - last/outlet lake basin of a multi-basin lake |
lake_depth | m | physical property | all | water depth below threshold for outlet lake (mean depth), can also be defined in GeoData.txt (must be > 0) |
area | m2 | physical property | all | lake or lake basin area, used for multi-basin lakes and to check which fraction of the sub-basin is covered by the outlet lake for simple outlet lakes (compared with SLC class fraction in GeoData.txt), mandatory for ldtype = 2 |
w0ref | m | general | 1/3/4 | reference water level to be added to simulated water level before print out, for lake outflow threshold |
deltaw0 | m | regulation | 1/3/4 | difference in lake threshold for regulation with two rating curves (m). Determines the lake threshold for regulation period 2 (w0=w0ref + deltaw0), see qprod1 and qprod2 |

datum1 | - | regulation | 1/3/4 | parameter for regulated olake, start of regulation period 1 (if not defined only one period is used) (4 character month-day string mmdd) |
datum2 | - | regulation | 1/3/4 | parameter for regulated olake, start of regulation period 2 (4 character month-day string mmdd) |
qamp | - | regulation | 1/3/4 | parameter for regulated olake, seasonally varying flow in regulated volume. Variation defined in form of a sinus wave with this amplitude (as fraction of current qprod), where the minimum of the sinus wave occurs for day number qpha |
qpha | - | regulation | 1/3/4 | parameter for regulated olake, seasonally varying flow below the threshold. day number for the minimum of the sinus wave. Default is qpha = 102. |
rate | m2/time step | regulation | 1/3/4 | parameter for specific rating curve of unregulated lakes or for spillway flow of regulated olakes above threshold (w0ref), equation q = rate (w - w0)^exp |
