Hello there. I’ve been trying to run my simulation on Mike 21/3 Coupled Model, but I kept on running into errors. Also, I can’t find the output file. In fact, I don’t know what it is like. The error message I got was “abnormal run completed”
I’m quite confused about the whole simulation process. Can anyone help, please?
Thank you.
Hello everyone.
I'm doing an evaluation of microplastics in several coastal species tissue samples, and what I want to know is what is the volume ratio of solvent:tissue to be used in the digestion process. The articles I read (not all literature, my bad.. my bad) are somewhat cryptic about that. They did mention volumes of solvent mixtures to then put them on tissues, but I'm interested in knowing, for instance, how much volume of KOH or H2O2 is necessary for achieve the digestion of shrimp tissue (such as the abdomen). Some papers mention 10 ml of 10%KOH but seems like is too little, and I found another that mentioned 150 ml. So, is there a precise volume? or you just simply add the solvent until covering the tissue. Or, because the incubation period, even a small volume of solvent is enough for the digestion purpose. Thanks for your time and (hopefully) answers.
Best wishes.
Dear All,
I have an issue regarding a sediment transportation simulation. I have computed the sediment transport rate based on a 20 years wave climate, and simulated the sediment drift for the total time span and either by monthly filtering of the data, the monthly sediment transport is also computed. However there is a problem that the summation of monthly sediment transport is much more than what I have calculated for the total time span. Is it possible this happening? Is there any reason behind this?
I appreciate it if you could share your Idea with me.

- I am trying to use the DSAS tool (version 5) for both ArcMap 10.4.1. and ArcMap 10.8 in Windows 10. I am able to output the transects, but when it comes to trying to calculate the statistic. I get an error message telling me to reference the DSAS_log (photo attached) (which does not provide a clear solution of what the error is). I wonder how to solve this problem? I have tried to re-create the baseline multiple times and am getting the same error for both two versions of ArcMap (10.4 &10.8). Knwoing that I followed the Guide and I am using (English US and mm/dd/yyyy format).
Littoral zone is wider than coastal zone, while second is a physical concept, littoral is also understood as social and economic. Which criteria could we use to draw the limits of littoral zone?
I am trying to run a coupled model (HD and SW MIKE 21), for a one year period (8760 time steps; 3600 time step interval). However, after approx 200 time steps there is an Abnormal Run error, 'Blow-Up wave height too large'. What are some reasons that would cause this, and some solutions?
I want to predict shoreline change in the future by the results or data of DSAS software. Could you please give me any advice?
Thanks so much!
Coastal management is a topic that has been much debated around the world in the last two decades, in view of the need to organize our coastal areas. In view of this context, I ask if the countries of South America present governmental programs of Coastal Management.
I want to publish my review paper in any reputed journal, but the time duration is less. Are there any free journals available to publish with in 2 months? Otherwise can you list trustworthy paid journals?
Hello everyone,
I work with the digital shoreline analysis system (DSAS of USGS) to my thesis, in the process i have a error with the calculate change statistics. The program say: "Unable to find output file 'C:\Users\...DSASCore.out.xml'
Does anyone know what the solution is?
Thanks!
I am conducting an investigation on the impact of heavy sands mining on human rights.
A mining company in northern Mozambique started mining on coastal sand dunes. The sand dunes are located between the sea in the east and a wetland in the west. There is a rural community standing on the sand dunes. In other words, the community is sandwiched between the sea and the wetland. Besides sea fishing, the community depends on the wetland's ecological services for survival.
The mining company began to dump mine sands on the wetland. This practice blocked natural water channels in the wetland; blocked the natural water channel that connected the wetland to the sea; and filled up a large part of the wetland with mine sand (reducing the wetland's water carrying capacity). This continued until the mining operation were now adjacent to the community -- about 200 meters away from the community.
When the rains came, the water could no longer flow into the sea and instead became trapped in the wetland. Eventually the water opened a channel to the sea through the middle of the village, destroying houses and property in its way.
My questions are:
1. What are the industry standards for heavy sands mining and how would they be applicable in this case?
2. What are the health risks associate with heavy sands mining for adjacent communities.
Thank you,
David
Is there any research or innovation related to storm water drainage for coastal urban areas? Generally pumping is used for effective drainage of low-lying coastal areas/towns. Can there be any other way?
Currently we are working in this field, applying the model of evolution proposed by Hoyle (1989) in ports of Argentina and the south of Brazil, and also adapting the model of Ducruet (2005) for its validation in Argentine port-cities. Although we have found similar studies in ports of Asia and Europe, it's been difficult to find other experiences in the region. Also, published papers in portuguese would be appreciated.
I want to do a new research by using remote sensing and GIS with oil (identifying, detecting, or any other application?
does anybody know where i can collect infrastructure systems (power systems) recovery data (after extreme disaster)? such as power systems recovery process after cascading blackout
Much of the water originates around these Himalayan mountains on earth, a region often called “the third pole” because of its immense concentration of snow and ice, the largest outside the Arctic and Antarctic. Protecting these Himalayas surface water resources requires a diagnosis of threat over a broad range.
Can you please suggest me the main concern problems and how to develop strategies for their sustainable development and water security.
Several papers are published about the Blue Flag (BF) eco-label program. Many of them criticize it, mainly because BF reduce ecosystem health of beaches and dunes or because it is not really understood by tourist. At the other side, many researchers and the organizations promoting BF highlight its benefits to improve beach quality, with focus in water quality and environmental awareness.
Within these two perspectives, are Blue Flag eco-label god or bad for beach quality (sanitary, ecosystem and recreation)?
Two papers I recommend to read, in order to contextualize question:
Botero, C., Pereira, C., Tosic, M., Manjarrez, G. 2015. Design of an index for monitoring the environmental quality of tourist beaches from a holistic approach. Ocean & Coastal Management 108: 65-73 DOI 10.1016/j.ocecoaman.2014.07.017 ISSN 0964-5691
Zielinski, S. Botero, C. 2015. Are eco-labels sustainable? Beach certification schemes in Latin America and the Caribbean. Journal of Sustainable Tourism 23:(10) 1550-1572. DOI: 10.1080/09669582.2015.1047376
I am beginning research into examining anticipated changes to beach availability and sea lion habitat from climate change impacts that might assist in predictive coastal management to reduce human/animal conflicts and support rescue networks on the coast of California. I cannot find any published research on the various search engines and was wondering if there are studies that have happened but not published or happening concurrently.

Dear All
I am working on numerical simulation of morphological changes in behind submerged breakwaters. At the present stage I need a set of useful experimental or field data, which could be used for validating the numerical model (in my case, DELFT3D).However, in spite of extensive search for such data, I could not find anything except some studies on emerged breakwaters.
Does anybody know where can I find such data?
In case no such data is available, what is the best approach for model validation?
Kind Regards
Methodologies that I have encountered thus far are 1). Ultrasonic sensors, 2) Hi-Res sonar, 3) Optical backscatter arrays (e.g., Sedimeter) and photovoltaic arrays (PEEP sensor), 4) Green-laser altimeters, 5) Load cells.
Do you know of other novel techniques that can measure fine-scale sedimentation in the offshore environment? Any favorite commercially-available instruments?
Thanks!
Kite Aerial Photography (KAP) has so many advantages that they are at least as suitable as UAVs for monitoring coastal dynamics.
Think about it, kites are:
- less regulated, which means higher altitudes thus wider footprints
- extremely inexpensive and portable
- non-intrusive, licensing-free
- wind-friendly, the more wind the more payload, thus, more sensors (RGB camera, micro-Lidar, Multispectral sensors, IMUs, GPS)
- less stable than UAVs, which is good for Structure from Motion algorithms because the same point is seen in diferent angles and scales and more off-nadir images means less doming effect
Obviously zero wind means no kites.But coastal areas are windy by nature.
Moreover, if you set target points, record accurate location (dGPS), then use the targets network to orthorectify the KAP imagery, Structure from Motion algorithms produce DSMs and Orthoimages as good as UAVs.
One of the most important coastal issue that has been tackled with a KAP approach received international attention in the 2014, when it was used for the worldwide famous Dutch project “Zandmotor”.
The point is:
Help me find at least 5 robust arguments that can refrain kites from being the next coastal monitoring tool.
Especially in Least Developed Countries or in Pacific Coutries where low-lying atolls are drowning and UAVs or fine resolution satellite imagery are just too expensive to use.
Cheers,
Nic
Hello.
I want to calculate the CVI along a coast. I have all the data needed. What troubles me is how to calculate the slope near the coast. The easy way is just to create a DEM and then use this to assign a value to a polyline representing the coast with multiple segments.
However if i do this, i take into account only the nearest cell of the slope Raster to the coast..
If i have pixel size of 5 m since i am working with maps of 1:5000 scale i think this is too narrow and not that representive of the whole beach slope..
Maybe it is a better way if i just measure the distance to the contour of 1 or meters and then calculate the slope that will be assigned to the polyline representing the coast?
What do you think?
Bottom-up, Top-down, management, Hegarty (1997), lagoon management
Does bottom- up approach in coastal lagoon management ensure proper utilization and management of lagoon resources?
Are there any limitations existing for the coastal states in its appliance of domestic legal sources?
e.g: Is it possible for states to apply "ordinance",ect., in dealing with certain issues when "law and regulations" are absent for this?
I am doing a research on marine debris stranded on coastal beach in relation to shipborne garbage.. The only reference i obtain is by Horsman, 1982.
How much water level fluctuation can occur near coastal zone?
If the water level variation is nearer to 20 m what can be cause?
Integrated Coastal Management (ICM) is considered as a governance process by Olsen, Lowry and Tobey (1999) and by Olsen and Nickerson (2003). However I realize and support the criterion that “Integrated Coastal Zone Management” (ICZM) is limited to a management process, not specifically a governance one. Governance addresses the values, policies, laws and institutions by which a set of issues are addressed (Olsen, 2003).
As distinct from State/local council policy & guidelines & theoretical modelling for climate change and coastal recession,I am interested in looking at adaptive or barrier based models specific to identified "at risk" locations on the Western Victorian Coastline. Sandy beach front communities in particular with minimal land area for urban expansion.
I am trying to find information or examples of beach nourishment in macro tidal areas. Mainly, I want to have an idea of the challenges faced when dealing with these kind of designs.
In the areas I'm looking at (6 m tidal range, 5 - 50 km fetch, no swell, low gradient profile), medium to fine sand is found only in the subtidal and supratidal region, with the intertidal region composed mainly by gravel. This might point to the use of hard engineering methods as well.
Any help is appreciated.
The mangroves play a very important role in stabilizing the fragile coastal regions of our planet. What can be done to avoid the depletion of the precious mangroves?
Community based management
Co-management
Ecosystem based management
Explain briefly if you select an option
I'm trying to detect maximum run up occured during nigth from a coastal video monitoring system. Attached is typical image where soil moisture difference is quite obvious, some times is not that much.
Any suggestions are welcome
I am looking for as many case studies as possible which showcase government/community efforts to invest in marine and coastal ecosystems as economic infrastructure. In other words, spending financial resources to enhance or restore these ecosystems. Case studies from developing countries in particular would be much appreciated!
I am trying to assess the Socio-economic relationship with coastal sciences for better prediction and management of coastal zones.
The shore protection manual (USACE, 1984) recommends a value of K = 0.39 that was derived from the original field study by Komar and Inman (1970) using tracers. In recent studies, (Schoonees and Theron, 1993) and (Schoonees and Theron, 1996) the 46 most reliable of the 240 existing field measurements that have been compiled to determine a K-value of approximately 0.2 were re-examined. Is there any study for calculation of K carried out so for ?
Please compare the strengths as well as limitations of these two models. Also the answer should consider the recent advancement as far as possible in both the models.
I'm looking for methods to make measurements of sediments transport close to sea bottom along shore from different direction. I'm looking for simple sediment traps which are used to measure such horizontal transport.
In the coming year, are there any comference calling for abstracts focusing on ecosystem services, or coastal/marine planning and management?
Can anyone suggest some methods to be implemented for an indicator based monitoring of coastal ecosystems? Can anyone also suggest articles?
I have a series of depth-damage functions to estimate damages caused by river flooding. I would like to use these functions as proxy to assess coastal flood damages. We know that damages caused by salt-water will be higher (due to salt content, intrusive water, soil quality lost, etc.). I am looking for specific figures relating damages caused by river and coastal flooding.
