Technical Architecture:
This software is developed in C# within the .NET Framework environment, designed with a multi-layer architecture, and utilizes local databases.

Operational Logic:

The ِDischarge – Stage Software is a specialized tool in the field of hydrometry and water resources management, designed to calculate river and canal flow discharge based on water level (stage) data. Its foundation lies in one of the most widely applied empirical methods in hydrology—the Stage–Discharge Curve. This curve establishes the relationship between water stage and flow discharge, allowing users to estimate instantaneous or daily flow rates at a station from observed stage levels.

The software provides a wide range of features, including manual entry or Excel-based import of water stage data, definition of stage–discharge curves for individual stations, generation of analytical charts, calibration of curves using field measurements, and preparation of detailed analytical reports. Developed with the aim of enhancing accuracy, speed, and data consistency, the software serves as a reliable replacement for manual calculations or fragmented spreadsheets.

Why Discharge – Stage?

Recording and processing discharge and stage data: Receiving and separating daily and hourly data, as well as flood and non-flood conditions.

Defining and managing stage–discharge curves: The ability to define multiple curves for different time periods.

Daily and peak discharge calculation: Accurate calculation of discharge using curves.

Drawing cross-sectional and longitudinal profiles: For analyzing flow and river conditions.

Data quality monitoring: Checking data accuracy and issuing error alerts.

Advanced reporting: Outputs in numerical, graphical, and rating table formats.

Manual and automatic interpolation: Filling missing data with precise methods.

User access management: Defining access levels to ensure data security.
