Inventory of Shared Water Resources in Western Asia

image of Inventory of Shared Water Resources in Western Asia
This publication is the first UN-led effort to make a comprehensive assessment of the state of transboundary surface and groundwater resources in the Middle East. It follows a standardized structure, with eight surface water chapters and 19 groundwater chapters that systematically address hydrology, hydrogeology, water resources development and use, international water agreements and transboundary water management efforts. The chapters cover all rivers and groundwater resources shared between Arab countries in the Middle East and include data on water resources that are shared with Iran, Israel and Turkey. Boasting over 50 new maps and 200 figures, tables and boxes with recent, comprehensive data series, the Inventory provides an up-to-date view of the state and evolution of shared water resources in the region.



Overview & methodology: Surface water

Part I of the Inventory provides a comprehensive overview of shared (transboundary) surface water basins in Western Asia. This chapter presents the methodology and approaches used to identify, delineate, characterize and describe these shared water resources in the Inventory. After defining the terminology used in the surface water chapters, all shared surface water resources in the region are listed together with the list of chapters for Part I of the Inventory. The section also explains why certain shared tributaries were covered in a single chapter and why some river basins were dealt with in separate chapters. The second part of the chapter outlines the Inventory’s approach to basin delineation, describes the structure of the surface water basin chapters and explains how the content of basin chapters was prepared and collated in a structured and unified way.
