Pilot Project Navigation with Nature®: a CoVadem application for the Chindwin River Myanmar
Deltares, together with Covadem B.V. and CDR international B.V. are partnering in a consortium to research the applicability of the Covadem Technology in unregulated rivers; unlike the context of the first application of Covadem in the regulated Rhine. This research will take place in a pilot project subsidised by the partners for water programme. The project “The Navigation with Nature approach - empowered by CoVadem” is a combination of a service and a
technology bringing four fields of expertise together: ICT for IWT, use of Big Data, river dynamics, water level forecasting, and the Geographical Information Systems (GIS); and also includes a business case. The ambition of this research is to provide an innovative, sustainable, affordable and efficient solution to the navigation problems in unregulated rivers, which can be scaled-up to become a knowledge-based commercial service. This research promotes the Building with Nature principles; supports the sustainable development goals (improves livelihood of people in remote and rural areas), and builds a knowledge-based niche position for the Dutch water sector.
Doel van het project
The main aim of this project is to further deepen broaden and integrate our knowledge and improve our tools (add-ons and coupling) for the situation of highly morphodynamic rivers to be able to link multiple sources of data with models in an operational mode.The data sources include:
depth data collect by vessels sailing along a given route via CoVadem Box
meteorological data from local stations and from open sources
discharge and water level data from measurement stations and
river planform from satellite images.
The models include:
Hydrological (rainfall run-off) model for discharge computation
hydrodynamic model for water level computation.
The tools and add-ons aim to:
generate bed level and consequently depth maps from scarce data (few ships equipped with CoVadem and low traffic intensity and
develop an approach that is suitable for morphodynamic active rivers.
The research component in this project focuses on the data-model integration data assimilation techniques and the development of tools.
Inland waterway transport is an excellent example of ecosystem services that benefit societies living around rivers. The dominant approach has been to adapt the river by means of river engineering measures to facilitate the navigation needs (viz. stable deep channel). However this approach disrupts the natural system and leads to long term impacts on the riverine environment. To minimise such impacts the concept of Building with Nature emerged.With the recent technological development in the digitalisation domain (e.g. connectivity and availability of large open source datasets) it is possible to take a step forward to enable an improved operational management approach of the fairway. Building on the CoVadem technology (www.covadem.org) that offers new opportunities to manage the navigation the shipping can be adapted to the changing river conditions rather than the river being adapted to the shipping needs this concept is called Navigation with Nature and will be piloted in the Chindwin river in Myanmar. The concept is particularly relevant for morphodynamic active rivers (e.g. Ayeyarwady Mekong Rio Magdalena etc.). These rivers share a common aspect of having a rather fast migration of the navigation channel which may shift hundreds of meters during a wet season. Consequently navigation may be hampered because of these changing conditions ultimately risking accidents by grounding vessels. Such an approach also supports navigation in a more sustainable way by reducing the dependency on hard interventions. (www.covadem.org) offers new opportunities to manage the inland waterwayDeltares with CoVadem Services and CDR international are aiming to build on the recent developments of CoVadem to offer solutions which are applicable for rivers other than the Rhine where the technology has been developed. In that there are new challenges that require improvement of our knowledge about data-model integration automated utilisation of data feeds from the ves
Within this project the following main activities will be carried out:
1- Modelling in data-scarce environment utilising earth observation datasets in combination with local measurements (Industrieel onderzoek)
1.1- Catchment modelling:We further develop adapt and utilise the recently developed rapid hydrological modelling approach (3 clicks to model) to build and utilise models for data scarce environment – upscaling to application in relation to CoVadem.
1.2- Hydrodynamic modelling one-dimensional modelling of long river reach in a data scarce environment.We further develop adapt and utilise the recently developed EO-Rivers toolbox which is rapid river model building python toolbox that is recently developed to function within Delta Shell – upscaling to application in relation to CoVadem.
2- Configuration of an operational navigation depth forecast system (using FEWS) based on CoVadem Technology (Industrieel onderzoek)
2.1- Transformation of the specific FEWS configuration for a more generic applicability.The CoVadem system has been developed for the specific settings of the Rhine in the Netherlands. The challenge here is to transform such configuration to suite generic cases and suitable for the international market.
2.2- API adaption to allow the system to function in the cloudSo far the forecasting system is run locally. The next step is to enable the operationalisiation of the system in its entirety in the cloud (Amazon cloud)
3- Waterway depth forecasting procedures - (Industrieel onderzoek):
3.1 - Develop a methodology to deal with planform changes
3.2- Develop an approach for depth map creation suitable for scarce data (suitable for few number of vessels and low frequency of traffic)
The CoVadem technology has been developed in the context of the Rhine River which is a trained river with a stable navigation channel. The navigation intensity and the number of vessels with the CoVadem box are sufficiently many such that high quality data can be obtained. And models are well developed for operational use. These conditions are not the same the Chindwin River which is morphologically active deep channel position changes over time with few ships using the CoVadem box. Innovation is needed to enable the utilisation of the CoVadem technology for these conditions which is prevailing in many rivers.We can list a number of challenges that require innovation as follows: Modelling in a data-scarce environment Integration of meteorological datasets from open source data or global models (e.g. GLOFFIS) with data from local sources to improve the quality of the predictions of discharge and subsequently water levels. Development of an approach to identify river planform changes and major shifts in the location of the deep channel and to enable the assimilation of such information in updating the navigation route and update the hydrodynamic model with the most recent dimensions. Assimilation of the scarce depth data coming from the few vessels equipped CoVadem box with pre-exiting bed level data to maximise the quality of the navigation depth prediction. Offering Cloud computing based services which involves running the entire system in the cloud.
