Rivers of the Silk Roads: how water shaped societies and empires in Central Asia 

(Leverhulme Trust funded project) 

 

36 month PDRA (£34,304 starting salary) with expertise in remote sensing and hydraulic modelling required from September 1^st, 2022 to work with Professor Mark Macklin (University of Lincoln, UK) and Dr Willem Toonen (Vrije Universiteit Amsterdam, Netherlands)  

 

Project summary and PDRA role: The importance of Central Asia’s Silk Roads to world history is well known. But what is not understood is the role that rivers in the region played in the development of nomadic and urban societies, and empires, particularly irrigation-based agriculture but also as water-rich corridors for pastoralists and travellers. Rivers of the Silk Roads is a novel and ambitious interdisciplinary project which uses state-of-the-art dating, hydraulic modelling and satellite imaging techniques, combined with archaeological investigations of ancient canal systems, to provide the first multi-millennial length reconstructions of changing water resources and water hazards along Central Asia’s Silk Roads. The PDRA will facilitate process-based connections between short- and long-term hydroclimatic change and the dynamics of regional flood-irrigation networks in each study area. Site based reconstructions will be made of flood regime changes in order to infer water availability for irrigation. Combined with a functional analysis of irrigation-canal networks, based on remote sensing and field investigations, agricultural yield will be modelled. The PDRA, supervised by Professor Macklin and Dr Toonen, will undertake two work packages.

 

WP1. Remote sensing and mapping of irrigation infrastructure, palaeochannels and canals, alongside ancient settlement distribution. Using high-resolution, gridded dataset of Earth’s floodplains generated from Shuttle Radar Topography Mission, and declassified CORONA satellite images, the PDRA will map (GIS-aided visual interpretation) and then digitise canal networks and associated field systems. CORONA images (1960-1972; KH-4B) are easily accessible from the USGS EROS Archive, have high spatial resolution (1.8-2.7 m) and because these are amongst the earliest imagery available across Central Asia, they predate the considerable damage and loss of archaeological sites (including ancient canals and field systems) that has happened over the last 40 years as a result of agricultural and urban development. All data, including new and recorded archaeological sites, will be mapped and archived using ArcGIS with the intention of developing an open-access GIS that would be made available to researchers and heritage managers in both Central Asia and more widely. From these analyses the PDRA will establish the form and phases of irrigation infrastructure in each of the study areas, including quantitative information on canal system length and dimensions, as well as the total area of irrigated fields and how these developed and changed over time.

WP2. Hydraulic modelling of canal systems to assess the likely population size they could sustain based on irrigation-supported agricultural yield, and how this may have changed over time. The cross sectional area and slopes of canals for each phase of irrigation development will be surveyed and, using an appropriate roughness value derived from Manning’s equation, their maximum flow carrying capacity calculated. To evaluate the performance of canal networks for different time periods, with respect the volume of flow and the areas of irrigated land that they could support, the PDRA will use the US Corps of Engineers Hydrologic Engineering Center’s (2009) HEC-GeoRAS model. Average spring and summer flows from the feeder river systems based on

gauged, tree ring and palaeohydrological estimates (determined from the dimensions of feeder channels contemporary with the phase of irrigation being modelled will be numerically routed through the canal system to evaluate the performance of the canal network. This will include determining if the feeder canal was able to supply all of the secondary canals simultaneously or if it was necessary to create a schedule of rotating water delivery. The PDRA will use the United Nations FAO “CROPWAT” software, to calculate the amount of water to grow staple cereal crops and vegetables that require irrigation, and compare this with estimated flows in canal systems for each time period.

 

For further information please email Professor Mark Macklin (mmacklin@lincoln.ac.uk) or Dr Willem Toonen (w.h.j.toonen@vu.nl). The successful applicant should be available to start this post on September 1^st 2022, or very shortly after this date. 

 

On 16 and 17 June the recurrent Ems-Scheldt Symposium will be held in Wageningen, where scientists and practitioners gather to focus on (bio)physical processes and the associated ecosystem services in the Ems and the Scheldt estuaries. All interested are invited to participate. If you intend to give a presentation during this German-Dutch-Belgian symposium, then a short abstract is required (https://event.wur.nl/ems-scheldt2022/subscribe)

The NCR DAYS 2022 Book of Abstracts is now available for download from our publication portal.

The abstract submission deadline for NCR Days 2022, “Anthropogenic Rivers” has been extended to March 8, 2020!

We invite you to submit a two-page abstract about your work to the 2022 NCR DAYS at Delft University of Technology. More information can be found on the event website.

Delft University of Technology is proud to host the NCR DAYS 2022 “Anthropogenic Rivers” on April 13-14. For more information, see the event page.

Dear all,

We are happy to announce that, as an alternative to our biennial River, Coastal and Estuarine Morphodynamics (RCEM) Meeting, we will host three virtual RCEM Zoom sessions this year:

• 30 Nov 2021 (16:00-19:00 CET) “System response to anthropogenic impact and climate change” Astrid Blom, Laura Stancanelli & Shelby Marie Ahrendt, contact astrid.blom@tudelft.nl
• 2 Dec 2021 (8:30-12:00 CET)  “Ecomorphodynamics” Nunzio Siviglia, Stefano Lanzoni & Guido Zolezzi, contact annunziato.siviglia@unitn.it
• 9 Dec 2021 (16:00-19:00 CET)  “Morphodynamics and sediment transport”Volker Weitbrecht & Cristina Rachelly, contact (Volker) wv@ethz.ch

The goal is to provide a cross-cutting forum for scientific discussion in the spirit of RCEM (i.e., using combinations of theoretical, observational, experimental and modelling approaches), especially targeted at young researchers (graduate, PhD students, early-career post docs).

We have different time slots between sessions to allow people from different parts of the globe to attend. The sessions will be recorded, unless a speaker requests otherwise. This will allow folks who are in time zones that don’t permit live attendance to view talks post session. Each session comprises one keynote presentation (to be announced) and a limited number of shorter presentations.

ABSTRACT SUBMISSION.

Please express your interest in giving a short presentation by sending a max 200-word abstract through this form: https://forms.gle/5A5fTACCdK8wf8Cg7. In the selection of presentations, we will aim for diversity in the speaker list and a balanced contribution from the major RCEM research fields (river – coast – estuary). The deadline for abstract submission is Monday 8 November 2021.

REGISTRATION.

Please register to attend the sessions here: https://forms.gle/HJLB4nRVKmiaZ6mFA. You will receive a calendar invite with a Zoom link (and password). The full program for the 3 sessions will be announced around 20 November, 2021.

We hope you will be able to join!

All the best, the RCEM team

The next edition of the annual meeting of the Netherlands Centre for River Studies (the NCR Days) will be organized by Rijkswaterstaat and will take place on February 13 and 14, 2020.

The program will based upon the main river functions that Rijkswaterstaat works on – water safety, clean and healthy water, fast and safe water-borne transport, and water availability. Rijkswaterstaat contributes to The Integral River Management (IRM) program, one of the main programs of the Dutch Ministry of Infrastructure and Watermanagement. The key task of IRM is to support those functions in a sustainable  and efficient way, and do so under the changing physical an social conditions. The central theme of the NCR days is therefore titled “Managing Changing Rivers”.
