Summer Course - Water Accounting Plus for Standardized Reporting of Water Resources in River Basins

Get an introduction to a new in-house developed international analytical framework in the field of water resources. This framework is rapidly expanding because various decision makers need to have independent and open access data that can be technically provided by Water Accounting Plus (WA+). 

For whom?

Summer courses at IHE Delft are for advanced students and professionals in the water and related sectors.

Learning objectives

Upon completion, the participant should be able to:
  1. Becoming familiar with the concept of Water Accounting, and specifically with the Water Accounting Plus framework
  2. Gain knowledge existing open access databases for (RS) water related data
  3. Being able to perform simple spatial calculations (using QGIS for Water Accounting)
  4. Learn how to compute water productivity
  5. Being able to understand (interpret) the WA+ accounting sheets. How can I use WA+ fact sheets to support IWRM?
  6. Being able to understand and use Water-Pix (pixel-based RS water balance tool)
  7. Learn how to separate evapotranspiration (ET) into green and blue ET

Programme

Day 1: FUNDAMENTAL CONCEPTS OF WATER ACCOUNTING PLUS (WA+)

Introduction to the need of an open access data. Discussion of the power of having verified information on water budgets for water policy negotiations and water management in general. Introduction to the Water Accounting Plus system. Fundamental concepts: water balance, green and blue water consumption, Budyko theory, explain coupled radiation - energy - water - carbon balances, consumptive and non-consumptive use, return flows, atmospheric moisture recycling. Theory and excel exercises (ET separation, water budget, green and blue water).

Day 2: ACCOUNTING SHEETS AND SPATIAL DATA

Group discussion on major challenges in water management. Computational steps of the Water Accounting Plus framework. Sheet 1,2 and 3: theory, exercise and group discussion. Discuss exploitable, available, utilized, non-utilized and utilizable flows in river basin. Introduction to earth observation science and the progress achieved on spatially identifying hydrological processes (rainfall, evapotranspiration, soil moisture, water levels, land use, net primary production) and water management (withdrawals, irrigation, drainage) from satellite measurements. Hands-on QGIS. DEMO on spatial data platform from where water resources related information can be collected. Introduction to the case study: Tonle Sap basin (Cambodia), QGIS exercise: coordinate reference system, basic statistics per land use using Remote Sensing Data

Day 3: ACCOUNTING SHEETS AND SPATIAL DATA (QGIS HANDS-ON)

Sheet 4, 5, 6, 7, and 8: theory, exercises and group discussion. Spatial data analysis: QGIS hands-on exercises (bias correction of Remote Sensing Precipitation, ET separation into green and blue water, ET partitioning into beneficial and non-beneficial, Remote Sensing vegetation data)

Day 4: WATER PRODUCTIVITY AND HYDROLOGICAL MODELING

Introduction to Water Productivity. Exercises on: Net Primary Production, accumulated biomass production and crop yield, biomass water productivity and crop water productivity (target values). Hydrological modelling of the earth systems with and without remote sensing assimilation. Exercise on soil moisture and surface runoff. Introduction to Water-Pix, pixel-based water balance, groundwater recharge and abstraction, exercises.

Day 5: CASE STUDY, DISCUSSION AND CLOSING REMARKS

Group work: prepare and discuss Sheet 1, Sheet 2 and Sheet 3 for the Tonle Sap basin, accounting sheets interpretation and scenario analysis. Discuss the services and benefits from water depletion, including agricultural and ecosystem services. Discuss sustainability of basin current and future conditions. Link these processes to water flows and fluxes. DEMO: water accounting software repository (GitHub). Closing remarks and final group discussion
