Integrated Hydroclimatic Analysis with ETP Variations

This workflow aims to enhance water resource management by combining temporal precipitation and temperature data from various sources. It performs essential hydroclimatic calculations, including potential evapotranspiration (ETP), useful rainfall (LLU), runoff (ESC), and infiltration (INF). Using data integration and interactive HTML graph generation, the workflow provides dynamic visual representations of precipitation trends, ETP dynamics, and correlations between temperature and precipitation. This comprehensive approach facilitates a deeper understanding of hydroclimatic patterns and supports effective water management decisions.

Background

Water resource management necessitates a comprehensive understanding of hydroclimatic patterns. This series of workflows addresses the amalgamation of temporal precipitation and temperature data from distinct sources to facilitate an integrated analysis. By unifying these datasets, the workflows perform initial processing and calculations, including the determination of potential evapotranspiration (ETP), useful rainfall (LLU), runoff (ESC), and infiltration (INF). The subsequent components generate interactive HTML graphs, providing valuable insights into hydroclimatic dynamics.

Introduction

Effective water resource management hinges on the ability to synthesize disparate datasets into a cohesive analysis. This series of workflows not only consolidates temporal precipitation and temperature data from various locations but also performs essential calculations to derive key hydroclimatic parameters. The resulting interactive graphs offer a dynamic visual representation of the cumulative deviation from the mean precipitation, temporal trends in precipitation (including ESC, INF, LLU, and total precipitation), ETP, daily and cumulative precipitation, temperature (maximum and minimum), and monthly precipitation.

Aims

The primary objectives of this workflow are tailored to address specific challenges and goals inherent in the analysis of ETP:

∙Data Integration: Unify temporal precipitation and temperature data from various sources into a coherent dataset for subsequent analysis.

∙Hydroclimatic Calculations: Calculate potential evapotranspiration (ETP), useful rainfall (LLU), runoff (ESC), and infiltration (INF) based on the integrated dataset. Note: ETP is calculated using formulas from different authors, including Hargreaves, Hamon, Jensen–Haise, Makkink, Taylor, Hydro Quebec, Oudin, and Papadakis.

∙Interactive Graph Generation: Utilize HTML to create interactive graphs representing cumulative deviation from the mean precipitation, temporal trends in precipitation (including ESC, INF, LLU, and total precipitation), ETP, daily and cumulative precipitation, temperature (maximum and minimum), and monthly precipitation.

Scientific questions

This workflow addresses critical scientific questions related to ETP analysis:

∙Temporal Precipitation Trends: Are there discernible patterns in the temporal trends of precipitation, and how do they relate to runoff, infiltration, and useful rainfall?

∙Potential Evapotranspiration (ETP) Dynamics: How does ETP vary over time using different authors' methods, and what are the implications for potential water loss?

∙Relationship Between Precipitation and Temperature: Are there significant correlations between variations in temperature (maximum and minimum) and the quantity and type of precipitation?

∙Seasonal Distribution of Precipitation: How is precipitation distributed across months, and are there seasonal patterns that may influence water management?
