Catchment and data assessment
Review of catchment boundaries, rainfall records and available data for the study scope.
Hydrological Studies and Flow Analysis
Hydrological studies for rainfall-runoff modelling, catchment characteristics and return-period flows. Discuss the data and reporting needs of your project.
Service scope and deliverables
Final deliverables, input data and project requirements are agreed during the quotation stage.
Return-period flow calculations
Flow calculations with a method selected for the catchment and data, including the calculation assumptions.
Hydrological study report
Data sources, methods and results presented within the agreed reporting scope.
What information is needed for a quote?
- Project location, study area and catchment boundary, if available.
- Available rainfall/flow records and topographic data.
- Project purpose, required return periods and any technical requirements from the reviewing authority.
If some data is not ready, share what you have so we can discuss how the gaps affect the study scope.
How the work progresses
- We review the location, project purpose and available data to define the scope.
- Methods, scenarios and technical outputs are defined in the quote.
- Analysis and reporting proceed within the agreed scope and data conditions.
Discuss your project scope
Share the location, project purpose, available data and required report. Scope and schedule are determined after the data review.
Expert Catchment Management
Hydrological science is the first step in understanding river behavior. Our process involves detailed spatial analysis of watersheds, historical rainfall data processing, and the application of synthetic unit hydrographs to predict future flood events.
We review the technical specifications applicable to the project and define the calculation methods, data sources and reporting scope accordingly.
Rational Method
Application for small catchments (< 2.5 km²) focusing on urban peak flow rates for local drainage systems.
SCS Mockus & Snyder
Utilizing synthetic unit hydrograph techniques for complex catchment response modeling in medium to large basins.
DSİ Sentetik Method
Implementation of the official DSİ synthetic unit hydrograph method specifically tailored for Turkish geographical conditions.
Intensity-Duration-Frequency
Processing historical rainfall data to generate IDF curves for infrastructure design return periods.
Frequently Asked Questions
It is a technical report that calculates the rainfall-runoff relationship, return period flood discharges (Q10, Q50, Q100, Q500), and the hydrological regime of a basin.
Rational Method, SCS Mockus, Snyder, and DSİ Synthetic Unit Hydrograph methods are used depending on the basin size.
The reviewing authority depends on the project location, type and application process. Technical requirements should be defined for the specific project.
