TLM
This tool is designed to assess hydrological drought and flood events. Threshold level or sequence peak algorithm methods can be used to evaluate extreme conditions. Segments with extreme conditions can be statistically processed and visualized.

TLM is prepared for the hydrological drought or flood analysis
using the threshold level method and method of sequent peak algorithm.
Into the program you can import time-series of daily discharges. For threshold
level definition is in prepared a comprehensive tool, where you can
threshold define and calculate.
Threshold level in program can be defined as:
- Annually constant threshold level
- Monthly constant threshold level
- N-daily constant threshold level
- Daily threshold level
- Seasonal (1-4 seasons) threshold level
- Explicitly defined threshold level
The following values can be set as the threshold level:
- Average values
- Median values
- Selected percentile values
- Directly specified values
After the threshold level definition and calculation you can use it for
analysis. Although the program was created for the purpose of
hydrological drought analysis, is possible also to analyse extremely
high values in time-series.
For the analysis of these extreme values you can use classic
threshold level method or sequent peak algorithm. Program calculates
new time-series of deficits (or reserves). Additionally, program
allows you to directly generate statistical table of individual deficit or flood events.
Results can be exported from application in table or graphical form.
